Marfan syndrome is a genetic disease, presenting with dysfunction of connective tissues leading to lesions in the cardiovascular and skeletal muscle system. Within these symptoms, the most typical is weakness of the connective tissue in the aorta, manifesting as aortic dilatation (aneurysm). This could, in turn, become annuloaortic ectasia, or life-threatening dissection. As a result, life-saving and preventative cardiac surgical interventions are frequent among Marfan syndrome patients. Aortic aneurysm could turn into annuloaortic ectasia or life-threatening dissection, thus life-saving and preventive cardiac surgical interventions are frequent among patients with Marfan syndrome. We hypothesized that patients with Marfan syndrome have different level of anxiety, depression and satisfaction with life compared to that of the non-clinical patient population. Patients diagnosed with Marfan syndrome were divided into 3 groups: those scheduled for prophylactic surgery, those needing acute surgery, and those without need for surgery (n = 9, 19, 17, respectively). To examine the psychological features of the patients, Spielberger's anxiety (STAI) test, Beck's Depression questionnaire (BDI), the Berne Questionnaire of Subjective Well-being, and the Satisfaction with Life scale were applied. A significant difference was found in trait anxiety between healthy individuals and patients with Marfan syndrome after acute life-saving surgery (p Marfan syndrome patients was 48.56 (standard deviation (SD): 5.8) as compared to the STAI population mean score of 43.72 (SD: 8.53). No difference was found between groups on the BDI (p > 0.1). Finally, a significant, medium size effect was found between patient groups on the Joy in Living scale (F (2.39) = 3.51, p = 0.040, η 2  = 0.15). Involving psychiatric and mental-health care, in addition to existing surgical treatment interventions, is essential for more successful recovery of patients with Marfan syndrome.

1998-01-01

To evaluate the effectiveness of pars plana vitreolensectomy in the management of subluxed lenses associated with Marfan's syndrome and to assess the need for intraoperative retinal photocoagulation to prevent post-operative retinal detachment. A retrospective review was carried out of 40 eyes of patients with Marfan's syndrome who underwent pars plana vitreolensectomy for subluxed lenses. All patients demonstrated stable or improved visual acuity following surgery with a low incidence of complications. Pars plana vitreolensectomy is a safe and effective treatment for subluxed lenses in patients with Marfan's syndrome. It appears that intraoperative prophylactic laser treatment need only be applied to areas of lattice degeneration to limit the incidence of post-operative retinal detachment.

Purpose To evaluate corneal air-puff deformation responses and ocular geometry as predictors of Marfan syndrome. Design Prospective observational clinical study Methods Sixteen investigator-derived, 4 standard Ocular Response Analyzer (ORA), and geometric variables from corneal tomography and optical biometry using Oculus Pentacam and IOL Master were assessed for discriminative value in Marfan syndrome, measuring right eyes of 24 control and 13 Marfan syndrome subjects. Area under the receiver operating characteristic (AUROC) curve was assessed in univariate and multivariate analyses Results Six investigator-derived ORA variables successfully discriminated Marfan syndrome. The best lone disease predictor was Concavity Min (Marfan syndrome 47.5 ± 20, control 69 ± 14, p = 0.003; AUROC = 0.80). Corneal hysteresis and corneal resistance factor were decreased (Marfan syndrome CH 9.45 ± 1.62, control CH 11.24 ± 1.21, p = 0.01; Marfan syndrome CRF 9.77 ± 1.65, control CRF 11.03 ± 1.72, p = 0.01) and corneas were flatter in Marfan syndrome (Marfan syndrome Kmean 41.25 ± 2.09 D, control Kmean 42.70 ± 1.81 D, p = 0.046). No significant differences were observed in central corneal thickness, axial eye length, or intraocular pressure. A multivariate regression model incorporating corneal curvature and hysteresis loop area (HLA) provided the best predictive value for Marfan syndrome (AUROC = 0.85). Conclusions This study describes novel biodynamic features of corneal deformation responses in Marfan syndrome, including increased deformation, decreased bending resistance, and decreased energy dissipation capacity. A predictive model incorporating HLA and corneal curvature shows greatest potential for non-invasive clinical diagnosis of Marfan syndrome. PMID:26432567

Marfan syndrome (MFS) is a pleiotropic connective tissue disease inherited as an autosomal dominant trait, due to mutations in the FBN1 gene encoding fibrillin 1. It is an important protein of the extracellular matrix that contributes to the final structure of a microfibril. Few cases displaying an autosomal recessive transmission are reported in the world. The FBN1 gene, which is made of 66 exons, is located on chromosome 15q21.1. This review, after an introduction on the clinical manifestations that leads to the diagnosis of MFS, focuses on cardiovascular manifestations, pharmacological and surgical therapies of thoracic aortic aneurysm and/or dissection (TAAD), mechanisms underlying the progression of aneurysm or of acute dissection, and biomarkers associated with progression of TAADs. A Dutch group compared treatment with losartan, an angiotensin II receptor-1 blocker, vs no other additional treatment (COMPARE clinical trial). They observed that losartan reduces the aortic dilatation rate in patients with Marfan syndrome. Later on, they also reported that losartan exerts a beneficial effect on patients with Marfan syndrome carrying an FBN1 mutation that causes haploinsufficiency (quantitative mutation), while it has no significant effect on patients displaying dominant negative (qualitative) mutations. Moreover, a French group in a 3-year trial compared the administration of losartan vs placebo in patients with Marfan syndrome under treatment with beta-receptor blockers. They observed that losartan decreases blood pressure but has no effect on aortic diameter progression. Thus, beta-receptor blockers remain the gold standard therapy in patients with Marfan syndrome. Three potential biochemical markers are mentioned in this review: total homocysteine, serum transforming growth factor beta, and lysyl oxidase. Moreover, markers of oxidative stress measured in plasma, previously correlated with clinical features of Marfan syndrome, may be explored as potential

To study ocular manifestations of Marfan syndrome in children and adolescents. Retrospective comparative cohort study on consecutive patients up to age 17 years, presenting to the interdisciplinary Marfan clinic of Charité-University Medicine Berlin over a period of 4 years. A total of 52 Marfan syndrome patients and 73 controls were enrolled. In Marfan syndrome eyes, the cornea was flatter (mean keratometry, 40.86 ± 2.13 vs 42.55 ± 1.55 diopters in control eyes, p Marfan syndrome eyes (537.35 ± 40.64 vs 552.95 ± 38.57 μm, p = 0.007) and Marfan syndrome eyes were more myopic than control eyes (spherical equivalent, -2.77 ± 4.77 vs -0.64 ± 1.92 diopters, p Marfan syndrome eyes. Iris transillumination defects were more common in Marfan syndrome eyes (19.6% vs 4.3% in control eyes, odds ratio for Marfan syndrome in the presence of iris transillumination defects = 7.2). Ectopia lentis was only found in Marfan syndrome eyes (25 Marfan syndrome patients, 49% with available data, bilateral in 68%). Iris transillumination defects and ectopia lentis are characteristic ocular findings in children and adolescents with Marfan syndrome. Myopia is more common and corneal curvature, central corneal thickness, and visual acuity are reduced in Marfan syndrome eyes. Children with Marfan syndrome need regular comprehensive eye examinations to identify potential complications.

Facial and Ocular Features of Marfan Syndrome

2014-10-01

Full Text Available Marfan syndrome is the most common inherited disorder of connective tissue affecting multiple organ systems. Identification of the facial, ocular and skeletal features should prompt referral for aortic imaging since sudden death by aortic dissection and rupture remains a major cause of death in patients with unrecognized Marfan syndrome. Echocardiography is recommended as the initial imaging test, and once a dilated aortic root is identified magnetic resonance or computed tomography should be done to assess the entire aorta. Prophylactic aortic root replacement is safe and has been demonstrated to improve life expectancy in patients with Marfan syndrome. Medical therapy for Marfan syndrome includes the use of beta blockers in older children and adults with an enlarged aorta. Addition of angiotensin receptor antagonists has been shown to slow the progression of aortic root dilation compared to beta blockers alone. Lifelong and regular follow up in a center for specialized care is important for patients with Marfan syndrome. We present a case of a patient with clinical features of Marfan syndrome and discuss possible therapeutic interventions for her dilated aorta.

Full Text Available Marfan syndrome is a disorder of the connective tissue (fibrillins and elastins. It is an autosomal dominant disease associated with a defect of chromosome 15 which encodes fibrillin-1. The syndrome is characterised by a varying extent of connective tissue disorders. A mutation in the gene encoding connective tissue can be manifested in all organs irrespective of the patient’s age. This disorder is characterised by multiple symptoms manifested mainly in the cardiovascular and skeletal systems as well as in the organ of vision. Ghent criteria are commonly recognised in the diagnosis of Marfan syndrome. Moreover, clinical symptoms reported by patients should also be considered. Patients presenting at the office of a general practitioner with symptoms resembling Marfan-like syndromes should undergo a detailed medical interview for the presence of cardiovascular diseases in the family. A general practitioner should examine the patient, drawing particular attention to organs that are frequently affected by disorders of connective tissue encoding (chest, oral cavity and general body stature. The family of a patient with Marfan syndrome should be referred to a genetic clinic to conduct tests for the presence of gene mutation. The diagnosis of Marfan syndrome in neonates is complex since not all symptoms of the syndrome are clinically manifested. In female patients with Marfan syndrome, pregnancy is contraindicated if the size of the aorta exceeds 50 mm. In other cases, women must be informed about possible risks and monitored for a change in the width of the aorta. Sometimes, procedures of prophylactic aortic replacement on its entire course are conducted prior to a planned pregnancy. Regular echocardiographic check-ups (every 4–7 weeks as well as cooperation of a gynaecologist and cardiologist are necessary. A general practitioner should inform the patient’s family about any sudden conditions that

Medical therapy with angiotensin II receptor blockers/angiotensin-converting enzyme inhibitors and/or beta-blockers was reported to reduce aortic root dilatation rates in pediatric patients with Marfan syndrome. No data are available in the literature on losartan effects after 3 years of therapy. The aim of our study was to establish whether losartan reduces aortic root dilatation rates in pediatric patients with Marfan syndrome in the mid and long term. This is a retrospective analysis of 38 pediatric patients with Marfan syndrome followed at the Marfan Clinic of S. Orsola-Malpighi Hospital of the University of Bologna (Italy). Aortic diameters were measured at sinuses of Valsalva and proximal ascending aorta with transthoracic echocardiography. After a mean follow-up of 4.5 ± 2.5 years (range 2-9 years), aortic root z score at sinuses of Valsalva and proximal ascending aorta remained stable. The average annual rate of change in aortic root z score was -0.1 ± 0.4 and 0 ± 0.3 at sinuses of Valsalva and proximal ascending aorta, respectively. The mean dose of losartan was 0.7 ± 0.3 mg/kg/day. Three patients were non-responders, probably because of late beginning or low dose of therapy. Eight patients underwent cardiac surgery (aortic root surgery in 5 and mitral valve repair in 3), all of them started losartan later in life. Despite the retrospective design of the study and the small sample size, a beneficial effect of losartan therapy was observed in pediatric patients with Marfan syndrome in the mid and long term. Late beginning or low doses of losartan can turn off the effects of therapy.

To evaluate the evolution of surgical management in a large population of patients with Marfan syndrome. This is a retrospective study of patients fulfilling the Ghent criteria for Marfan syndrome, who visited the Centre de référence national pour le syndrome de Marfan et apparentés and underwent a surgical event before or during follow-up in the centre. One thousand and ninety-seven patients with Marfan syndrome, according to international criteria, came to the clinic between 1996 and 2010. Aortic surgery was performed in 249 patients (22.7%; 20 children and 229 adults), including the Bentall procedure in 140 patients (56%) and valve-sparing surgery in 88 patients (35%); a supracoronary graft was performed in 19 patients (7.6%), usually for aortic dissection. During the past 20 years, the predominant reason for aortic surgery has switched from aortic dissection to aortic dilatation, while age at surgery has tended to increase (from 32.4 ± 11.9 years to 35.2 ± 12.4 years; P=0.075). Mitral valve surgery was performed in 61 patients (5.6%; six children and 55 adults), including 37 valvuloplasties (60.6%) and 18 mitral valve replacements (29.5%). No significant difference was observed when comparing mitral valve surgery before and after 2000. Surgery performed in patients with Marfan syndrome has switched from emergency surgery for aortic dissection to elective surgery for aortic dilatation; this is associated with surgery performed at an older age despite the indication for surgery having decreased from 60mm to 50mm. No significant evolution was observed for mitral valve surgery. Copyright © 2012 Elsevier Masson SAS. All rights reserved.

Marfan's syndrome is a rare inborn error of metabolism. Marfan patients are prone to aneurysms of the ascending aorta and run a high risk of rupture of the aortic arch. The diameter of the aneurysm is the most important predictor of the risk and therefore the leading point for surgical interventions. IV and IA-DSA according to our experiences are simple and effective methods in pre- and postoperative evaluation of patients with the syndrome.

Marfan syndrome is one of the collagen vascular diseases that theoretically predisposes patients to excessive radiation-induced fibrosis yet there is minimal published literature regarding this clinical scenario. We present a patient with a history of Marfan syndrome requiring radiation for a diagnosis of a right brachial plexus malignant nerve sheath tumor. It has been suggested that plasma transforming growth factor beta 1 (TGF-beta1) can be monitored as a predictor of subsequent fibrosis in this population of high risk patients. We therefore monitored the patient's TGF-beta1 level during and after treatment. Despite maintaining stable levels of plasma TGF-beta1, our patient still developed extensive fibrosis resulting in impaired range of motion. Our case reports presents a review of the literature of patients with Marfan syndrome requiring radiation therapy and the limitations of serum markers on predicting long-term toxicity.

The aim of this study is to describe a total endovascular aortic repair with branched and fenestrated endografts in a young patient with Marfan syndrome and a chronic aortic dissection. Open surgery is the gold standard to treat aortic dissections in patients with aortic disease and Marfan syndrome. In 2000, a 38-year-old man with Marfan syndrome underwent open ascending aorta repair for an acute type A aortic dissection. One year later, a redo sternotomy was performed for aortic valve replacement. In 2013, the patient presented with endocarditis and pulmonary infection, which necessitated tracheostomy and temporary dialysis. In 2014, the first stage of the endovascular repair was performed using an inner branched endograft to exclude a 77-mm distal arch and descending thoracic aortic aneurysm. In 2015, a 63-mm thoracoabdominal aortic aneurysm was excluded by implantation of a 4-fenestrated endograft. Follow-up after both endovascular repairs was uneventful. Total aortic endovascular repair was successfully performed to treat a patient with arch and thoraco-abdominal aortic aneurysm associated with chronic aortic dissection and Marfan syndrome. The postoperative images confirmed patency of the endograft and its branches, and complete exclusion of the aortic false lumen. Endovascular repair is a treatment option in patients with connective tissue disease who are not candidates for open surgery. Long-term follow-up is required to confirm these favorable early outcomes. Copyright © 2016 Elsevier Inc. All rights reserved.

Marfan syndrome (MFS) is an autosomal dominant connective tissue disorder typically involving the ocular, skeletal and cardiovascular systems, and aortic aneurysms/dissection mainly contributes to its mortality. Here, we performed genetic testing of the FBN1 gene in 39 Chinese probands with Marfan/Marfan-like syndrome and their related family members by Sanger sequencing. In total, 29 pathogenic/likely pathogenic FBN1 mutations, including 17 novel ones, were identified. In addition, most MFS patients with aortic disease (62%) had a truncating or splicing mutation. These results expand the FBN1 mutation spectrum and enrich our knowledge of genotype-phenotype correlations. Genetic testing for MFS and its related aortic diseases is increasingly important for early intervention and treatment. Copyright © 2016 Elsevier B.V. All rights reserved.

Endovascular surgery in Marfan syndrome: CON.

The frequency of endovascular stent grafting procedures to treat various conditions of the thoracic aorta has increased dramatically over the past three decades. Stent grafting has been applied on a limited basis in patients with Marfan syndrome and other connective tissue disorders, despite recommendations from current guidelines and expert consensus statements against its use in this setting. A review of publications reporting outcomes after stent grafting of the descending thoracic aorta in Marfan patients with acute or chronic aortic dissection indicates that these procedures can be accomplished with rates of early mortality, stroke and spinal cord ischemic injury that are comparable to those observed in patients who do not have Marfan syndrome. However, the rates of primary treatment failure (principally endoleak), secondary treatment failure, need for open repair and late death among the Marfan patients are substantially higher than those observed in patients without this condition. In addition, the rates of retrograde aortic dissection and development of stent-graft induced new entry (SINE), are also greater among patients with Marfan syndrome. All of these findings argue strongly against the routine use of endovascular grafts in Marfan patients with type B or residual type A dissection. Few data are available to assess the role of endografting in Marfan patients with aneurysmal disease, but the progressive aortic dilatation noted in these patients argues strongly against its use in this setting as well. At present, the available data indicate that there is no justification for elective stent grafting in Marfan patients with aortic dissection or aneurysm. The only reasonable indications for primary aortic stent grafting are in the setting of acute aortic dissection or rupture, where the intervention is considered life-saving and rarely, considering the relatively young age of these patients, where the risk of open operation is considered to be prohibitive.

Aim: Dural ectasia is a major diagnostic criterion for Marfan syndrome using the Ghent nosology. Our aim was to evaluate the efficacy of three different radiological methods previously proposed for the assessment of dural sac diameter in Marfan syndrome. Methods: Marfan syndrome was diagnosed in our study using the Ghent criteria, disregarding dural ectasia as a criterion. Three proposed radiological methods were applied to measure dural sac diameter, examined for 41 patients (18 patients with and 23 without Marfan syndrome) by computed tomography or magnetic resonance imaging. Results: Using Oosterhof's method, 94% of the patients with and 44% of the patients without Marfan syndrome fulfilled the criteria of dural ectasia. According to Villeirs, dural ectasia was diagnosed in 18% of the patients with and in none of the patients without Marfan syndrome. With Ahn's method, dural ectasia was found in 72% of the patients with and in 44% of the patients without Marfan syndrome. In only two patients with Marfan syndrome was dural ectasia diagnosed by all three methods. Conclusion: Our results reveal overt discrepancy between the three methods of assessing dural ectasia. Considering the key role played by dural ectasia in reinforcing the diagnosis of Marfan syndrome according to the Ghent nosology, a standardized and reliable method should be sought

Defective collagen biosynthesis in Marfan syndrome predisposes to dural defects such as dural ectasia, meningocele, and pseudomeningocele; thus, an increased index of suspicion for these conditions should be present in the clinical setting of Marfan syndrome. The authors describe a young woman with Marfan syndrome who was being treated with anticoagulants for a prosthetic heart valve and who presented with a spontaneous retroperitoneal hemorrhage requiring surgical evacuation. No CSF leak was encountered at surgery, but she developed progressively more severe positional headaches over the following year. She then experienced the sudden onset of acute urinary obstruction, at which time CT revealed a 17 × 15 × 13-cm presacral pseudomeningocele communicating with the thecal sac through a sacral bone defect. An anterior surgical approach was used for drainage of the pseudomeningocele as well as for primary closure of the dural defect with a bovine pericardial patch and autologous subcutaneous fat graft. After a short period of lumbar subarachnoid drainage of the CSF, the patient was able to resume normal activity without recurrent symptoms. To the authors' knowledge, such a pseudomeningocele in a patient with Marfan syndrome has been reported only twice, and this case features the largest pseudomeningocele to date. They also review the pertinent literature regarding presentation, diagnosis, and management of these lesions.

We assessed the surgical outcome of descending thoracic aortic aneurysm repair (DTAA) and thoracoabdominal aortic aneurym (TAAA) repair in patients with Marfan syndrome. During a six year period, 206 patients underwent DTAA and TAAA repair. In 22 patients, Marfan syndrome was confirmed. The median age was 40 years with a range between 18 and 57 years. The extend of the aneurysms included 6 DTAA (1 with total arch, 2 with distal hemi-arch), 11 type II TAAA (2 with total arch, 3 with distal hemi-arch), 4 type III and one type IV TAAA. All patients suffered from previous type A (n=6) or type B (n=16) aortic dissection and 15 already underwent aortic procedures like Bentall (n=7) and ascending aortic replacement (n=8). All patients were operated on according to the standard protocol with cerebrospinal fluid drainage, distal aortic and selective organ perfusion and monitoring motor evoked potentials. In patients undergoing simultaneous arch replacement (via left thoracotomy), transcranial Doppler and EEG assessed cerebral physiology during antegrade brain perfusion. In four patients circulatory arrest under moderate hypothermia was required. In-hospital mortality did not occur. Major postoperative complications like paraplegia, renal failure, stroke and myocardial infarction were not encountered. Mean pre-operative creatinine level was 125mmol/L, which peaked to a mean maximal level of 130 and returned to 92mmol/L at discharge. Median intubation time was 1.5 days (range 0.33-30 days). Other complications included bleeding requiring surgical intervention (n=1), arrhythmia (n=2), pneumonia (n=2) and respiratory distress syndrome (n=1). At a median follow-up of 38 months all patients were alive. Using CT surveillance, new or false aneurysms were not detected, except in one patient who developed a visceral patch aneurysm six years after open type II repair. Surgical repair of descending and thoracoabdominal aortic aneurysms provides excellent short- and mid-term results in

[Valve-sparing aortic root replacement for young female patients with Marfan syndrome].

Annuloaortic ectasia is frequently related with Marfan syndrome, and Bentall procedure or aortic root replacement with valved conduit has been the conventional standard operation for this disease. Recently, some institutes have adopted valve-sparing aortic root replacement (VSARR) instead of Bentall procedure. Young female patients with Marfan syndrome who wishes for childbearing seem to be a group of good candidates of this type of operation, because it let them free from morbidities after artificial valve implantation. Valve-sparing operation should be taken into consideration when the size of Valsalva sinus reaches 45 mm for patients with Marfan syndrome and when it reaches 40 mm for patients with past histories or family histories of aortic dissection or aortic rupture. Since pregnancy is one of the most serious risk factors for aortic events, Valsalva sinus of 40 mm or larger could be the new standard for surgical indication if VSARR is applicable.

To create a follow-up protocol for pregnant patients with Marfan syndrome. We retrospectively reviewed the charts of patients who delivered in the Jeanne de Flandre University Hospital between June 1996 and June 1999. Four pregnant patients with Marfan syndrome were identified. Three of these patients had Bentall procedure. One of them had vaginal delivery and the two others underwent cesarean section. One of these two patients developed aortic valve thrombus at 14 weeks of amenorrhea. The fourth patient did not have surgery and had two vaginal deliveries. According to our results and after reviewing literature pregnant patients with Marfan syndrome were divided into two groups. The 1st group was comprised of patients who underwent Bentall procedure. The 2nd one was comprised of patients who did not undergo any surgical procedure. The possibility of vaginal delivery for patients who underwent Bentall procedure (one case) and the interest of Propanolol and anticoagulant treatment are emphasized. The multivariant approach of pregnant patients with Marfan syndrome is stressed out with special reference to the potential complications of this syndrome such as aortic dissection and to the problems related to the anticoagulant treatment.

To characterize the incidence, severity, quality, and treatment of pain in a large cohort of Marfan patients. A web-based survey was distributed to all individuals on the Marfan Foundation listserv. Respondents who endorsed a diagnosis of Marfan syndrome were queried as to the presence, frequency, severity, location, and quality of their pain and were asked to describe the specific treatments used to manage pain. The primary outcome was the presence of pain symptoms in respondents during the 7-day period preceding completion of the survey. Of the 993 patients with a verified diagnosis of Marfan syndrome, 67% (95% confidence interval, 64%-69%) reported pain in the preceding 7 days. Median (interquartile range) "average daily pain" was 4 (3 to 5) on the numeric rating scale; "worst pain" was 7 (5 to 8). "Worst pain experienced" was ≥4 in 93% of respondents. Analgesic use to control pain related to Marfan syndrome was reported in 56% of respondents with 55% reporting Marfan patients are underestimated and likely undertreated. We propose a need for improved patient and medical provider awareness of pain management options in this population, including the development of effective algorithms to treat pain in Marfan patients.

Marfan syndrome is a genetic disorder with considerable morbidity and mortality. Presently, clinicians use the 2010 revised Ghent nosology, which includes optional genetic sequencing of the FBN1 gene, to diagnose patients. So far, only a few studies based on older diagnostic criteria have reported a wide range of prevalence and incidence. Our aim was to study prevalence, incidence, and age at diagnosis in patients with Marfan syndrome. Using unique Danish patient-registries, we identified all possible Marfan syndrome patients recorded by the Danish healthcare system (1977-2014). Following, we confirmed or rejected the diagnosis according to the 2010 revised Ghent nosology. We identified a total of 1628 persons with possible Marfan syndrome. We confirmed the diagnosis in 412, whereof 46 were deceased, yielding a maximum prevalence of 6.5/100,000 at the end of 2014. The annual median incidence was 0.19/100,000 (range: 0.0-0.7) which increased significantly with an incidence rate ratio of 1.03 (95% CI: 1.02-1.04, p Marfan syndrome during the study period is possibly due to build-up of a registry. Since early diagnosis is essential in preventing aortic events, diagnosing Marfan syndrome remains a task for both pediatricians and physicians caring for adults.

Marfan syndrome is an autosomal dominant heritable disorder of the connective tissue, caused by mutations of the gene FBN1, which encodes fibrillin-1, a major component of the microfibrils of the extracellular matrix. Fibrillin-1 interacts with transforming growth factor-β (TGF-β), and dysregulated TGF-β signaling plays a major role in the development of connective tissue disease and familial aortic aneurysm and dissection, including Marfan syndrome. Losartan, an angiotensin II blocker, has the potential to reduce TGF-β signaling and is expected to be an additional therapeutic option. Clinical diagnosis is made using the Ghent nosology, which requires comprehensive patient assessment and has been proven to work well, but evaluation of some of the diagnostic criteria by a single physician is difficult and time-consuming. A Marfan clinic was established at the University of Tokyo Hospital in 2005, together with cardiologists, cardiac surgeons, pediatricians, orthopedists, and ophthalmologists in one place, for the purpose of speedy and accurate evaluation and diagnosis of Marfan syndrome. In this review, we discuss the recent progress in diagnosis and treatment of Marfan syndrome, and the characteristics of Japanese patients with Marfan syndrome. © 2014 Japan Pediatric Society.

Marfan's syndrome is characterized by the formation of ascending aortic aneurysms resulting from altered assembly of extracellular matrix microfibrils and chronic tissue growth factor (TGF)-β signaling. TGF-β is a potent regulator of the vascular smooth muscle cell (VSMC) phenotype. We hypothesized that as a result of the chronic TGF-β signaling, VSMC would alter their basal differentiation phenotype, which could facilitate the formation of aneurysms. This study explores whether Marfan's syndrome entails phenotypic alterations of VSMC and possible mechanisms at the subcellular level. Immunohistochemical and Western blotting analyses of dilated aortas from Marfan patients showed overexpression of contractile protein markers (α-smooth muscle actin, smoothelin, smooth muscle protein 22 alpha, and calponin-1) and collagen I in comparison with healthy aortas. VSMC explanted from Marfan aortic aneurysms showed increased in vitro expression of these phenotypic markers and also of myocardin, a transcription factor essential for VSMC-specific differentiation. These alterations were generally reduced after pharmacological inhibition of the TGF-β pathway. Marfan VSMC in culture showed more robust actin stress fibers and enhanced RhoA-GTP levels, which was accompanied by increased focal adhesion components and higher nuclear localization of myosin-related transcription factor A. Marfan VSMC and extracellular matrix measured by atomic force microscopy were both stiffer than their respective controls. In Marfan VSMC, both in tissue and in culture, there are variable TGF-β-dependent phenotypic changes affecting contractile proteins and collagen I, leading to greater cellular and extracellular matrix stiffness. Altogether, these alterations may contribute to the known aortic rigidity that precedes or accompanies Marfan's syndrome aneurysm formation. © 2015 American Heart Association, Inc.

Abdominal Aortic Dissection with Acute Mesenteric Ischemia in a Patient with Marfan Syndrome

Directory of Open Access Journals (Sweden)

Chii-Shyan Lay

2006-07-01

Full Text Available Marfan syndrome is an autosomal dominant inherited disorder of connective tissue, with various complications manifested primarily in the cardiovascular system. It potentially leads to aortic dissection and rupture, these being the major causes of death. We report a patient who complained of acute abdominal pain, which presented as acute mesenteric ischemia combined with abdominal aortic dissection. Echocardiography showed enlargement of the aortic root and mitral valve prolapse. Abdominal computed tomography scan revealed acute mesenteric ischemia due to abdominal aortic dissection. Finally, the patient underwent surgery of aortic root replacement and had a successful outcome. Therefore, we suggest that for optimal risk assessment and monitoring of patients with Marfan syndrome, both aortic stiffness and the diameter of the superior mesenteric vein compared with that of the superior mesenteric artery are useful screening methods to detect acute mesenteric ischemia secondary to abdominal aortic dissection. Early diagnosis and early treatment can decrease the high mortality rate of patients with Marfan syndrome.

We report a case of acute coronary syndrome in a patient with suspect Marfan syndrome, 25 days after emergent modified Bentall-De Bono intervention for acute type I peripartum aortic dissection. She was admitted to our intensive care unit because of unstable angina, caused by critical blood flow reduction in a large portion of the myocardium, according to the severity of the symptoms and the electrocardiographic alterations. Coronary angiography showed a sub-occlusive stenosis of the left main coronary artery as a result of the dissection extension to the coronary ostium. Because of the high risk related to heart surgery, the patient was successfully treated by unprotected angioplasty and drug-eluting stent positioning. Short- and mid-term outcomes were favourable. Subsequent tests confirmed the diagnosis of Marfan syndrome. After 2 years of follow-up, the patient remains asymptomatic and in good health. To our knowledge, this is the first report of a successful percutaneous intervention of the left main coronary artery in a patient with Marfan syndrome who had already undergone ascending aortic root and valve replacement by the Bentall-De Bono procedure for acute dissection.

Bicuspid aortic valves are associated with valve dysfunction, ascending aortic aneurysm and dissection. Management of the ascending aorta at the time of aortic valve replacement (AVR) in these patients is controversial and has been extrapolated from experience with Marfan syndrome, despite the absence of comparative long-term outcome data. This study sought to assess whether the natural history of thoracic aortopathy after AVR in patients with bicuspid aortic valve disease is substantially different from that seen in patients with Marfan syndrome. In this retrospective comparison, outcomes of 13,205 adults (2,079 with bicuspid aortic valves, 73 with Marfan syndrome, and 11,053 control patients with acquired aortic valve disease) who underwent primary AVR without replacement of the ascending aorta in New York State between 1995 and 2010 were compared. The median follow-up time was 6.6 years. The long-term incidence of thoracic aortic dissection was significantly higher in patients with Marfan syndrome (5.5 ± 2.7%) compared with those with bicuspid valves (0.55 ± 0.21%) and control group patients (0.41 ± 0.08%, p Marfan syndrome (10.8 ± 4.4%) compared with those with bicuspid valves (4.8 ± 0.8%) and control group patients (1.4 ± 0.2%) (p Marfan syndrome were significantly more likely to undergo thoracic aortic surgery in late follow-up (10.4 ± 4.3%) compared with those with bicuspid valves (2.5 ± 0.6%) and control group patients (0.50 ± 0.09%) (p Marfan syndrome compared with those with bicuspid aortic valves confirm that operative management of patients with bicuspid aortic valves should not be extrapolated from Marfan syndrome and support discrete treatment algorithms for these different clinical entities.

We report a case of partial lobectomy in a patient with Marfan syndrome. A 56-year-old woman with Marfan syndrome was scheduled for partial lobectomy for suspected lung cancer under general anesthesia. She underwent a Bentall operation and mitral valve replacement 10 months before and strict blood pressure management was required. After induction of general anesthesia with propofol and fentanyl, topical intratracheal lidocaine anesthesia was performed using the Pentax-AWS Airwayscope (AWS) for visualization, allowing for the Soft-tipped Tube Exchanger (TE-Soft) to be inserted into the trachea. Next, a double-lumen tracheal tube was uneventfully intubated via the TE-Soft with minimal change in vital signs. During the operation, pressure-controlled ventilation was performed to minimize the risk of pneumothorax. After the operation, under continuous administration of landiorol and dexmedetomidine, the double-lumen tracheal tube was extubated uneventfully. Strict airway and circulation management is needed for lung or vessel preservation in patients whose conditions are complicated by Marfan syndrome.

Marfan syndrome is a multisystem connective tissue disorder, with primary involvement of the cardiovascular, ocular, and skeletal systems. This autosomal heritable disease is mainly attributable to a defect in the FBN1 gene. Clinical diagnosis of Marfan syndrome has been based on the Ghent criteria since 1996. In 2010, these criteria were updated, and the revised guidelines place more emphasis on aortic root dilation, ectopia lentis, and FBN1 mutation testing in the diagnostic assessment of Marfan syndrome. Among its many different clinical manifestations, cardiovascular involvement deserves special consideration, owing to its impact on prognosis. Recent molecular, surgical, and clinical research has yielded profound new insights into the pathological mechanisms that ultimately lead to tissue degradation and weakening of the aortic wall, which has led to exciting new treatment strategies. Furthermore, with the increasing life expectancy of patients with Marfan syndrome, there has been a subtle shift in the spectrum of medical problems. Consequently, this article focuses on recent advances to highlight their potential impact on future concepts of patient care from a clinical, surgical, and anesthetic perspective. © The Author(s) 2013.

Marfan syndrome is associated with morbidity and mortality due to aortic dilatation and dissection. Preventive aortic root replacement has been the standard treatment in Marfan syndrome patients with aortic dilatation. In this study, we present aortic event data from a nationwide Marfan syndrome cohort. The nationwide cohort of Danish Marfan syndrome patients was established from the Danish National Patient Registry and the Cause of Death Register, where we retrieved information about aortic surgery and dissections. We associated aortic events with age, sex, and Marfan syndrome diagnosis prior or after the first aortic event. From the total cohort of 412 patients, 150 (36.4 %) had an aortic event. Fifty percent were event free at age 49.6. Eighty patients (53.3 %) had prophylactic surgery and seventy patients (46.7 %) a dissection. The yearly event rate was 0.02 events/year/patient in the period 1994-2014. Male patients had a significant higher risk of an aortic event at a younger age with a hazard ratio of 1.75 (CI 1.26-2.42, p = 0.001) compared with women. Fifty-three patients (12.9 %) were diagnosed with MFS after their first aortic event which primarily was aortic dissection [n = 44 (83.0 %)]. More than a third of MFS patients experienced an aortic event and male patients had significantly more aortic events than females. More than half of the total number of dissections was in patients undiagnosed with MFS at the time of their event. This emphasizes that diagnosing MFS is lifesaving and improves mortality risk by reducing the risk of aorta dissection.

We report our experience with aortic valve-sparing procedures in patients with Marfan syndrome and aortic root aneurysm. Between August 2003 and July 2007, we performed aortic valve-sparing procedures in 20 patients with aortic root aneurysm resulting from Marfan syndrome. Mean age was 28 +/- 10 years (range, 10 to 57 years), and there were 9 females and 11 males. A reimplantation technique was used in 9 cases, a remodeling technique in 8 and a patch technique in 3 cases. Additional procedures included total aorta replacement in 1 patient, and aortic arch replacement plus stented elephant trunk in 2 patients. The mean follow-up time was 46 +/- 16 months (range, 17 to 64 months). No in-hospital or late death occurred. Reexploration for bleeding was required in one case on postoperative day 1. No valve-related complications occurred during the follow-up period. At the end of follow-up, trivial or no aortic regurgitation was demonstrated in 14 patients, mild in 4 patients, moderate in 1 and severe in 1. Two patients with moderate and severe aortic regurgitation required reoperation. The early and mid-term results of the valve-sparing operations were favorable, and the durability of the preserved valve should encourage use of this technique in patients with Marfan syndrome.

A case of persistent bilateral perilunate dislocation unrelated to trauma in a patient with Marfan syndrome is discussed. This finding is believed to be a manifestation of the generalized ligamentous laxity occurring in this disorder. Radiographs of eight additional Marfan syndrome patients failed to demonstrate similar carpal instability. Because some carpal derangements are dynamic events, stress views or wrist fluoroscopy may be necessary to demonstrate unsuspected carpal instability in Marfan patients.

The appropriateness of aortic valve-sparing operations in patients with Marfan syndrome has been questioned. This study examines the long-term results of these operations in patients with Marfan syndrome. From 1988 to 2006, 103 consecutive patients with Marfan syndrome (mean age, 37 +/- 12 years) and aortic root aneurysm had aortic valve-sparing operations. Emergency surgery was performed in 11 patients: 8 for acute type A aortic dissection and 3 for unexplained persistent chest pain. Fourteen patients also had mitral valve surgery. The technique of aortic valve reimplantation was used in 77 patients, and aortic root remodeling was used in 26 patients. Patients were followed prospectively and underwent annual echocardiographic studies. The mean follow-up was 7.3 +/- 4.2 years and 100% complete. There was 1 operative death and 5 late deaths. Four of the 6 deaths were due to complications of aortic dissections. The patients' survival at 15 years was 87.2% compared with 95.6% for the general population of Ontario matched for age and sex. Seven patients had important aortic insufficiency: 4 mild to moderate, 2 moderate, and 1 moderate to severe. Freedom from greater than mild aortic insufficiency at 15 years was 79.2%. Three patients, all after aortic root remodeling, had aortic valve replacement, 2 for aortic insufficiency and 1 for endocarditis. At the most recent follow-up, 97 patients were alive: 86 were in functional class I, and 11 were in functional class II. Aortic valve-sparing operations provided excellent clinical outcomes in this series of patients with Marfan syndrome. Postoperatively, complications of aortic dissections were the leading cause of death.

Marfan syndrome is the most common inherited connective tissue disorder, affecting approximately 1 in 10,000 live births. The cardinal features of Marfan syndrome are the abnormalities of the skeleton (tall stature, arachnodactyly, and joint hyperelasticity), eye (lens subluxation), and aorta (root aneurysm with proclivity toward rupture and dissection). Aortic catastrophe accounts for most of the premature mortality among Marfan patients, a risk that climbs steeply during adolescence and results in death of half of Marfan patients by the age of 40 years. Most of the improvement in life expectancy that has been achieved in Marfan syndrome is attributable to early recognition of aortic root aneurysms and prophylactic replacement with composite grafts (mechanical valve prostheses within Dacron conduits) before rupture or dissection occurs. Despite the excellent early and late results with composite grafts, there has been growing interest in operative procedures that replace the sinuses but preserve the aortic valve leaflets, to avoid anticoagulation and minimize the risk of prosthesis-related endocarditis. These procedures are still in evolution and late results are not yet known, but as with mitral repair in the setting of myxomatous disease, valve-sparing procedures in Marfan syndrome have weathered a storm of initial criticism and skepticism and are steadily gaining acceptance.

History  A 30-year-old man presented with a history of progressive muscle weakness, difficulty in concentrating, and a slender habitus since early childhood. Marfan syndrome was suspected since the age of 14. Examinations  13 years later he was examined by Marfan experts and by genetic testing and Marfan syndrome could not be confirmed. Further neurological examination revealed the suspected diagnosis of myotonic dystrophy type 1, which was confirmed by genetic testing. Treatment and course  Similar to Marfan syndrome, myotonic dystrophy is a multisystemic disorder with the risk of cardiac arrythmias. It is necessary to provide an interdisciplinary care by neurologists, internists, ophthalmologists, speech therapists, and physiotherapists. Conclusion  It is not enough to take the habitus as the principle sign to diagnose Marfan syndrome. Furthermore, it is essential to consider symptoms that are not typical for Marfan syndrome, such as cognitive deficiencies or progressive paresis. © Georg Thieme Verlag KG Stuttgart · New York.

1986-01-01

Gated MR imaging was used to evaluate the thoracic aorta in 11 with Marfan syndrome, eight patients with aneurysm of the ascending aorta, and 20 healthy subjects. The aortic diameter was measured on transverse and sagittal images at the levels of the sinuses of Valsalva, the caudal portion of the ascending aorta, the prearch region, the middle arch, and the descending aorta. The sinus of Valsalva-prearch region aortic diameter ratio in patients with Marfan syndrome was significantly greater than in the two other groups, indicating the characteristic shape of the Maranoid aorta. MR imaging allows definitive measurements' of aortic dimensions and is a valuable noninvasive method for monitoring the course of aortic enlargement

Marfan syndrome (MS) is a connective tissue disorder that affects thousands of adolescents [Population Reference Bureau, 2013]. Some adolescent patients with MS may use social media to express their experiences and emotions, but little is known about what patients choose to share online. To investigate social media content related to Marfan syndrome we used search terms "Marfan syndrome" and "Marfans" on six different social media sites. The top five recent and popular posts for each site were collected and coded weekly for five weeks. Posts were excluded if they were reshared content or not in English. A codebook was developed using an iterative process to categorize posts and comments. Out of 300 posts collected 147 posts (49.0%) were included for evaluation. Categories of displayed content included personal pictures, memes and pictures featuring symptoms of MS (41.5%) and personal MS experiences (27.1% of posts). One quarter of the posts specifically mentioned a positive experience or how thankful the profile owner was for their life. A unique category of posts (13.7%) referenced Austin Carlile, a celebrity singer with MS, as a role model. Physicians and healthcare providers may consider using social media to understand common MS concerns and to place future health education materials. © 2015 Wiley Periodicals, Inc.

A case of persistent bilateral perilunate dislocation unrelated to trauma in a patient with Marfan syndrome is discussed. This finding is believed to be a manifestation of the generalized ligamentous laxity occurring in this disorder. Radiographs of eight additional Marfan syndrome patients failed to demonstrate similar carpal instability. Because some carpal derangements are dynamic events, stress views or wrist fluoroscopy may be necessary to demonstrate unsuspected carpal instability in Marfan patients. (orig.)

As the shortcomings of the Bentall operation and its variants in the Marfan syndrome have become apparent, the recent cusp-sparing techniques (remodeling or reimplantation) bear promise of better mid-term and long-term outcomes. To examine the results of aortic root surgery in patients with Marfan syndrome. During the period March 1994 to September 2007, 220 patients underwent aortic valve-sparing surgery; 20 were Marfan patients (group 1) who were compared with another 20 Marfan patients undergoing composite aortic root replacement (group 2). Fourteen patients had aortic dissection and 26 had thoracic aortic aneurysm. There were 31 males and 9 females with a mean age of 37.9 +/- 13.8 years. In group 1, reimplantation was used in 13 patients, remodeling in 4, and aortic valve repair with sinotubular junction replacement in 3. In group 2, a mechanical valve conduit was used. Mean logistic Euroscore was 12.27 +/- 14.6% for the whole group, five of whom were emergent cases Group 2 had more previous cardiac procedures compared to group 1 (9 vs. 2, P = 0.03) and shorter cross-clamp time (122 +/- 27.1 vs. 153.9 +/- 23.7 minutes, P = 0.0004). Overall mortality was 10%. Early mortality was 10% in group 2 and 5% in group 1 (NS). Mean follow-up time was 25 months for group 2 and 53 months for group 1. Three patients were reoperated; all had undergone the remodeling. Five year freedom from reoperation and death was 86% and 90% in group 2 and 70% and 95% in group 1 (P = 0.6, P = 0.6), respectively. Late survival of patients with Marfan syndrome was similar in both groups. Root reconstruction tends towards a higher incidence of late reoperations if the remodeling technique is used. We now prefer to use the reimplantation technique.

Without treatment, the life expectancy of patients with Marfan syndrome is reduced by the associated cardiovascular abnormalities. In this study, we reviewed our experience of the patients with Marfan syndrome who required multiple surgical interventions to identify the optimal treatment for these patients. Between January 1986 and December 2000, 44 patients with Marfan syndrome were operated on at Shizuoka City Hospital (SCH). Among them, 10 patients (22.7%) underwent multiple surgical interventions. There were 5 male and 5 female patients with a mean age of 40.6 +/- 16.1 years at the initial surgery. Only one patient was operated on at another hospital for his first, second, and third operations. His fourth operation was carried out at SCH. The remaining 9 patients underwent a total of 14 additional surgical procedures at SCH. Computed tomography (CT) scans were taken every 6 months postoperatively, and aortic diameter greater than 60 mm was considered as the indication for the additional surgery. There were no early death and one late death. The causes of additional surgery were enlargement of true aneurysm in 6, enlargement of residual dissection in 4, new dissection in 4, false aneurysm at the coronary anastomosis of Bentall procedure in 1. In 9 patients, both ascending and descending aorta were replaced. Among these 9 patients, only 3 patients underwent total arch replacement, and remaining 6 patients had their arch left in place with or without dissection. Our current strategy of the treatment of Marfan patients with acute type A dissection is total arch replacement with an elephant trunk at the initial emergent surgery.

A well-established association exists between acute aortic dissection and pregnancy, particularly in women with Marfan syndrome. However, there is debate regarding appropriate management guidelines. In particular, there are differing opinions regarding when prophylactic aortic root repair should be recommended as well as the efficacy of beta blockers in this clinical scenario. The current study evaluated 10 years of published literature (2005-2015) in the PubMed/Medline database. Fifty articles, describing 72 cases of women who presented with aortic dissection in the antepartum or postpartum period were identified. Comparisons on demographic variables and clinical outcomes between cases of women with Marfan syndrome (n = 36) and without Marfan syndrome (n = 36) were conducted. There were no significant differences in demographics (age, gravidity, parity) between the Marfan and non-Marfan cases. Marfan patients presented with antepartum dissections significantly earlier in pregnancy than those without Marfan syndrome (P = .002). However, there were no significant difference between the 2 groups in maternal mortality, fetal mortality, or obstetric outcomes (mode of delivery and gestational age at delivery). Eight cases described events in Marfan women with an aortic root diameter ≤40 mm. Six events occurred in Marfan women who were managed with beta blockers. Current guidelines rely on aortic root diameter for stratification of Marfan women into risk categories, but we identified several cases that would be missed by these guidelines. Specifically, the existing literature suggest that women with Marfan syndrome should take precautions throughout pregnancy, rather than the third trimester. © 2017 Wiley Periodicals, Inc.

Spontaneous pneumothorax and apical bulla are included in minor criteria of the diagnosis of Marfan's syndrome. We evaluated the frequency of radiological abnormal findings of the lung in Marfan's syndrome. Lungs could be assessed with CT in 38 cases that were selected from 50 cases in Marfan's syndrome with a cardiovascular disease or the valvular disease. Eleven cases (22%) in 50 cases had the past history of spontaneous pneumothorax. Chest CT scan in 38 cases showed emphysematous bullae in 12 cases, apical scar in eight cases, centrilobular emphysema in three cases, and bronchiectasis in one case. CT manifestations of the lung in Marfan's syndrome were mainly spontaneous pneumothorax and apical bullae as were previously reported. (author)

This study examines pedicle widths, laminar thicknesses, and scalloping values for lumbosacral spine elements in Marfan volunteers. Comparisons were made between these measurements and norms as well as measurements between Marfan patients with and without dural ectasia. To determine if the lumbosacral vertebral elements are altered in the patient with Marfan syndrome. Several abnormalities have been noted in Marfan lumbar spine, including pedicular attenuation and widened interpediculate distances. This may be due to abnormalities of growth or presence of dural ectasia. Given the large numbers of Marfan patients requiring spinal surgery and the high postoperative failure rate, better understanding of the bony anatomy of Marfan lumbar spine is necessary, especially if use of instrumentation is anticipated. Thirty-two volunteers with Marfan syndrome based on the Ghent criteria underwent spiral computed tomography of the lumbosacral spine. Images were evaluated for dural ectasia, and measurements of pedicle width, laminar thickness, and vertebral scalloping were made. Pedicle widths and laminar thicknesses were significantly smaller in Marfan patients at all levels (Plaminar thickness from L5-S2 and pedicle widths at all lumbar levels were significantly reduced (Plaminar thickness are significantly reduced in Marfan individuals. Those with dural ectasia demonstrate increased bony erosion of anterior and posterior elements of lumbosacral spine. Preoperative planning and routine computed tomography scans are recommended when operating on Marfan lumbosacral spine.

The involvement of the musculoskeletal system with other mild pleiotropic manifestations represents a clinical criterion, called "systemic features," to d iagnose Marfan's syndrome. We aimed to investigate the features of the hands and feet redressable contractures present in a group of Marfan patients. In 13 patients with previously diagnosed Marfan's syndrome, an accurate clinical examination was performed. In particular the characterization of the musculoskeletal system by visual analogic scale to measure muscle pain (VAS) and muscle strength (MRC system) was carried out; the Beighton scale score was used to evaluate the articular hypermobility. Ultrasound examination (US) was performed to detect deep-superficial flexor tendons and extensor tendons of both hands, and the short and long flexor and extensor tendons of the fingers and toes in static and dynamic positions. The ImageJ program was adopted to measure a profile of tendon echo-intensity. A reduction of the thickness of all tendons was detected by US in our patients; the VAS and Beighton scale scores were in normal ranges. The profile of tendon echo-intensity showed different textural details in all Marfan patients. This study provides evidence for other contractures' localization, and for altered findings of the tendons in patients with Marfan syndrome and finger/toe contractures. These changes may be associated with structural modifications in connective tissue.

Marfan syndrome is an inherited disorder characterized by genetic abnormality of microfibrillar connective tissue proteins. Endothelial dysfunction is thought to cause aortic dilation in subjects with a bicuspid aortic valve; however, the role of endothelial dysfunction and endothelial damaging factors has not been elucidated in Marfan syndrome. Flow-mediated dilation, a noninvasive measurement of endothelial function, was evaluated in 39 patients with Marfan syndrome. Aortic diameter was measured at the aortic annulus, aortic root at the sinus of Valsalva, sinotubular junction and ascending aorta by echocardiography, and adjusted for body surface area (BSA). The mean value of flow-mediated dilation was 6.5 ± 2.4 %. Flow-mediated dilation had a negative correlation with the diameter of the ascending thoracic aorta (AscAd)/BSA (R = -0.39, p = 0.020) and multivariate analysis revealed that flow-mediated dilation was an independent factor predicting AscAd/BSA, whereas other segments of the aorta had no association. Furthermore, Brinkman index had a somewhat greater influence on flow-mediated dilation (R = -0.42, p = 0.008). Although subjects who smoked tended to have a larger AscAd compared with non-smokers (AscA/BSA: 17.3 ± 1.8 versus 15.2 ± 3.0 mm/m(2), p = 0.013), there was no significant change in flow-mediated dilation, suggesting that smoking might affect aortic dilation via an independent pathway. Common atherogenic risks, such as impairment of flow-mediated dilation and smoking status, affected aortic dilation in subjects with Marfan syndrome.

Marfan syndrome has a pleomorphic phenotype. Those affected have abnormalities in the eyes and in the nervous, cardiovascular and musculoskeletal systems. Among these abnormalities are many reported aneurysms, involving the ascending, descending thoracic and abdominal aorta, the sinus of Valsalva, and the internal carotid artery. We report a left internal mammary artery (LIMA) aneurysm in a patient with Marfan syndrome and no other known predisposition to such an aneurysm. No other case of LIMA aneurysm in Marfan syndrome has, to our knowledge, been reported. (author)

The Florida sleeve (FS) procedure was developed as a simplified approach for repair of functional type I aortic insufficiency secondary to aortic root aneurysm. We evaluated postoperative aortic valve function, long-term survival, and freedom from reoperation in Marfan syndrome patients who underwent the FS procedure at our center. All Marfan syndrome patients undergoing FS procedure from May 2002 to December 2014 were included. Echocardiography assessment included left ventricular end-diastolic diameter (LVEDD), left ventricular end-systolic diameter (LVESD), ejection fraction, and degree of aortic insufficiency (none = 0, minimal = 1, mild = 2, moderate = 3, severe = 4). Social Security Death Index and primary care physicians' report were used for long-term follow-up. Thirty-seven Marfan syndrome patients, 21 (56.8%) men and 16 (43%) women with mean age of 35.08 ± 13.45 years underwent FL repair at our center. There was no in-hospital or 30-day death or stroke. Two patients required reoperation due to bleeding. Patients' survival rate was 94% at 1 to 8 years. Freedom from reoperation was 100% at 8 years. Twenty-five patients had postoperative follow-up echocardiography at 1 week. Aortic insufficiency grade significantly decreased after the procedure (preoperative mean ± SD: 1.76 ± 1.2 versus 1-week postoperative mean ± SD: 0.48 ± 0.71, p Marfan syndrome patients with immediate improvement in aortic valve function. Long-term survival and freedom from reoperation rates are encouraging. Copyright © 2017 The Society of Thoracic Surgeons. Published by Elsevier Inc. All rights reserved.

Patients with Marfan syndrome require repeated imaging for monitoring of aortic root aneurysms. Therefore, we evaluated the agreement and reproducibility of cine-MRI and echocardiography measurements of the sinuses of Valsalva in patients with suspected Marfan syndrome. 51 consecutive patients with suspected Marfan syndrome were prospectively examined using cine-MRI and echocardiography. Two readers independently measured aortic root diameters at the level of the sinuses of Valsalva in both cine-MRI and echocardiography. Statistics included intraclass correlation coefficient, Pearson correlation coefficient, Bland-Altman analysis, and two-sided t-test. In 38 of the 51 individuals (74.5 %), the diagnosis of Marfan syndrome was established according to the criteria of the Ghent-2 nosology.

Aortic disease is the main cause of death among patients with Marfan syndrome. Before the development of open surgery, most patients died in the fourth decade of life. Improvements in surgical techniques have facilitated prophylactic surgery and have dramatically changed the life expectancy of patients with Marfan syndrome. Valve-sparing techniques are becoming the standard surgical treatment for these patients, since the operative and long-term results are comparable with those obtained with the Bentall and De Bono procedure and their theoretical advantages over the Bentall and De Bono procedure are attractive for young patients. Distal aortic complications still cause substantial morbidity in patients who have undergone surgery. On the other hand, several medical approaches have appeared as alternatives or adjuncts to the standard treatment with beta-blockers. Mouse models of the disease have shown that the angiotensin II receptor blocker losartan can rescue the phenotype. Among female patients, pregnancy deserves special consideration. Aortic dissection occurs mainly in the third trimester of gestation and in patients with dilated aortas. As aortic dissection carries a high risk of maternal mortality and fetal demise, prophylactic aortic surgery is recommended before attempting pregnancy for those women with an aortic diameter exceeding 40 mm.

Full Text Available Marfan syndrome is an autosomal dominantly inherited disorder of connective tissue with prominent skeletal, ocular, and cardiovascular manifestations. Aortic aneurysm and dissection are the major determinants of premature death in untreated patients. In previous work, we showed that extracts of aortic tissues from the mgR mouse model of Marfan syndrome showed increased chemotactic stimulatory activity related to the elastin-binding protein. Aortic samples were collected from 6 patients with Marfan syndrome and 8 with isolated aneurysms of the ascending aorta. Control samples were obtained from 11 organ donors without known vascular or connective tissue diseases. Soluble proteins extracted from the aortic samples of the two patient groups were compared against buffer controls and against the aortic samples from controls with respect to the ability to induce macrophage chemotaxis as measured using a modified Boyden chamber, as well as the reactivity to a monoclonal antibody BA4 against bioactive elastin peptides using ELISA. Samples from Marfan patients displayed a statistically significant increase in chemotactic inductive activity compared to control samples. Additionally, reactivity to BA4 was significantly increased. Similar statistically significant increases were identified for the samples from patients with idiopathic thoracic aortic aneurysm. There was a significant correlation between the chemotactic index and BA4 reactivity, and the increases in chemotactic activity of extracts from Marfan patients could be inhibited by pretreatment with lactose, VGVAPG peptides, or BA4, which indicates the involvement of EBP in mediating the effects. Our results demonstrate that aortic extracts of patients with Marfan syndrome can elicit macrophage chemotaxis, similar to our previous study on aortic extracts of the mgR mouse model of Marfan syndrome (Guo et al., Circulation 2006; 114:1855-62.

Marfan syndrome is a multisystemic genetic condition affecting connective tissue. It carries a reduced life expectancy, largely dependent on cardiovascular complications. More common cardiac manifestations such as aortic dissection and aortic valve incompetence have been widely documented in the literature. Mitral valve prolapse (MVP), however, has remained poorly documented.

The cooccurrence of Marfan syndrome and psychiatric disorders has been reported for many years. Furthermore, neuropsychological deficits have been shown to be associated with Marfan syndrome. The aim of the present article is to summarize findings from the sparse studies and case reports available. The results hold clinical and therapeutic implications and suggest that psychological and neuropsychological domains in Marfan syndrome patients should be carefully assessed. In particular, some patients may require specific rehabilitation programs. On this basis, a multidisciplinary approach to Marfan syndrome treatment seems mandatory. © The Author(s) 2015.

Patients with Marfan syndrome are at risk for ascending aortic dilation and dissection at the level of the aortic sinuses, making aortic root and valve replacement common. Patients undergoing an aortic root replacement with concomitant replacement of the aortic valve with a bioprosthesis (Bio-Bentall) are predisposed to bioprosthesis failure. Transcatheter aortic valve implantation (TAVI) has become an option for aortic valve replacement, avoiding cardiopulmonary bypass and/or median sternotomy. We present the first 2 reported patients with Marfan syndrome who underwent a valve-in-valve TAVI in the setting of a prior Bio-Bentall. © 2014 S. Karger AG, Basel.

Marfan syndrome is a systemic disorder of connective tissue, caused by mutations in the FBN1, TGFBR1 or TGFBR2 genes. This syndrome is characterized by involvement of three major systems, skeletal, ocular, and cardiovascular. The continuing improvements in molecular biology and increasing availability of molecular diagnosis in clinical practice allow recognition of Marfan syndrome in patients with incomplete phenotypes. Additionally, molecular analyses could also be used for preimplantation genetic diagnosis. The identification of a mutation allows for early diagnosis, prognosis, genetic counseling, preventive management of carriers and reassurance for unaffected relatives. The importance of knowing in advance the location of the putative family mutation is highlighted by its straightforward application to prenatal and postnatal screening.

The outcome of aortic valve-sparing root reconstruction in Marfan syndrome was reviewed. Thirteen patients with Marfan syndrome underwent aortic valve-sparing root reconstruction for annuloaortic ectasia or aortic root dissection between 1994 and 1999. The grade of preoperative aortic regurgitation was I in 4, II in 2, III in 5, IV in 2 patients. The procedures of aortic valve-sparing were reimplantation in 7 and remodeling in 5 patients. There was no hospital and late death. Recurrence of aortic regurgitation greater than moderate grade developed in 1 patient immediately after the surgery and in the other 4 patients in the late stage. One patient of them required aortic valve replacement for it. Aortic valve-sparing root reconstruction is applicable in Marfan patients, although the indication should be cautious. Close observation is needed for recurrence of aortic regurgitation.

Aortic dissections involving the descending aorta are a major clinical problem in patients with Marfan syndrome. The purpose of this study was to identify clinical parameters associated with type B aortic dissection and to develop a risk model to predict type B aortic dissection in patients with Marfan syndrome. Patients with the diagnosis of Marfan syndrome and magnetic resonance imaging or computed tomographic imaging of the aorta were followed for a median of 6 years for the occurrence of type B dissection or the combined end point of type B aortic dissection, distal aortic surgery, and death. A model using various clinical parameters as well as genotyping was developed to predict the risk for type B dissection in patients with Marfan syndrome. Between 1998 and 2013, 54 type B aortic dissections occurred in 600 patients with Marfan syndrome (mean age 36 ± 14 years, 52% male). Independent variables associated with type B aortic dissection were prior prophylactic aortic surgery (hazard ratio: 2.1; 95% confidence interval: 1.2 to 3.8; p = 0.010) and a proximal descending aorta diameter ≥27 mm (hazard ratio: 2.2; 95% confidence interval: 1.1 to 4.3; p = 0.020). In the risk model, the 10-year occurrence of type B aortic dissection in low-, moderate-, and high-risk patients was 6%, 19%, and 34%, respectively. Angiotensin II receptor blocker therapy was associated with fewer type B aortic dissections (hazard ratio: 0.3; 95% confidence interval: 0.1 to 0.9; p = 0.030). Patients with Marfan syndrome with prior prophylactic aortic surgery are at substantial risk for type B aortic dissection, even when the descending aorta is only slightly dilated. Angiotensin II receptor blocker therapy may be protective in the prevention of type B aortic dissections. Copyright © 2015 American College of Cardiology Foundation. Published by Elsevier Inc.

Neonatal Marfan syndrome is a rare and severe phenotype of this disease. A poor prognosis is anticipated due to the high probability of congestive heart failure, and mitral and tricuspid regurgitations with suboptimal response to medical therapy and difficulties in surgical management at an early age. We present two consecutive patients with this disease who are the first reported cases from Iran to the best of our knowledge. Unfortunately both of them died shortly after diagnosis. Neonatal Marfan syndrome is reported from Iran and has a poor prognosis like the patients reported from elsewhere.

Cardiac manifestations of Marfan syndrome include aortic root dilation and mitral valve prolapse (MVP). Only scant data exist describing MVP in patients with Marfan syndrome undergoing aortic root replacement. We retrospectively analyzed data from 166 MFS patients with MVP who were enrolled in a prospective multicenter registry of patients who underwent aortic root aneurysm repair. Of these 166 patients, 9% had mitral regurgitation (MR) grade >2, and 10% had MR grade 2. The severity of MVP and MR was evaluated by echocardiography preoperatively and ≤ 3 years postoperatively. Forty-one patients (25%) underwent composite graft aortic valve replacement, and 125 patients (75%) underwent aortic valve-sparing procedures; both groups had similar prevalences of MR grade >2 (P=0.7). Thirty-three patients (20%) underwent concomitant mitral valve (MV) intervention (repair, n=29; replacement, n=4), including all 15 patients with MR grade >2. Only 1 patient required MV reintervention during follow-up (mean clinical follow-up, 31 ± 10 months). Echocardiography performed 21 ± 13 months postoperatively revealed MR >2 in only 3 patients (2%). One early death and 2 late deaths occurred. Although the majority of patients with Marfan syndrome who undergo elective aortic root replacement have MVP, only 20% have concomitant MV procedures. These concomitant procedures do not seem to increase operative risk. In patients with MR grade ≤ 2 who do not undergo a concomitant MV procedure, the short-term incidence of progressive MR is low; however, more follow-up is needed to determine whether patients with MVP and MR grade ≤ 2 would benefit from prophylactic MV intervention.

Marfan syndrome is a heritable, systemic disorder of the connective tissue with a high penetrance, named after Dr. Antoine Marfan. The most clinically important manifestations of this syndrome are cardiovascular pathologies which cause life-threatening events, such as acute aortic dissections, aortic rupture and regurgitation of the aortic valve or other artrioventricular valves leading to heart failure. These events play important roles in the life expectancy of patients with this disorder, especially prior to the development of effective surgical approaches for proximal ascending aortic disease. To prevent such catastrophic aortic events, a lower threshold has been recommended for prophylactic interventions on the aortic root. After prophylactic root replacement, disease in the aorta beyond the root and distal to the arch remains a cause for concern. Multiple surgeries are required throughout a patient's lifetime that can be problematic due to distal lesions complicated by dissection. Many controversies in surgical strategies remain, such as endovascular repair, to manage such complex cases. This review examines the trends in surgical strategies for the treatment of cardiovascular disease in patients with Marfan syndrome, and current perspectives in this field.

This study was undertaken to assess the frequency and outcome of cardiovascular surgery in children with Marfan or Loeys-Dietz syndrome. A retrospective review from 2 regional Marfan subspecialty clinics was performed. Between 1997 and 2007, 204 children with Marfan syndrome and 17 children with Loeys-Dietz syndrome were followed serially. Of these patients, 35 were identified who had undergone cardiovascular surgery at 18 years of age or less. Demographic, echocardiographic, and surgical data were collected. Surgery was performed at a median of 3 years (0-15 years) after diagnosis and a mean age of 11.5 +/- 6.2 years. Aortic root replacement was the initial surgery in 30 patients, and mitral valve surgery was the initial surgery in 8 patients, with 3 patients undergoing both. Aortic root replacement was performed using a composite root replacement in 9 patients and valve-sparing techniques in 21 patients (remodeling in 8 patients and reimplantation in 13 patients). Eight patients underwent reoperation at a mean of 4.7 +/- 3.0 years after aortic surgery: 3 for aortic insufficiency, 2 for dissection, 2 for valve thrombosis, and 1 for a distal aneurysm. Adverse outcomes included reoperation in 8 patients, aneurysm in 1 patient, and death due to dissection or stroke in 3 patients. Variables associated with an adverse outcome included preoperative aortic insufficiency, valve replacement, and absence of angiotensin-converting enzyme inhibitor therapy. Patients with Marfan or Loeys-Dietz syndrome requiring surgery during childhood have a favorable long-term outcome. Those undergoing valve-sparing root replacement or mitral valve repair have a low risk for reoperation. Postoperative angiotensin-converting enzyme inhibitor therapy confers clinical benefit.

Marfan syndrome is a rare multisystem disease of the connective tissue, which affects multiple organ systems. advances in healthcare have doubled the life-expectancy of patients over the past three decades. to date, there is no comprehensive review that consolidates economic considerations and care for marfan patients. Areas covered: Present research suggests that there may be a link between treatment pattern, disease progression and economic costs of Marfan syndrome. It indicates that an early detection of the disease and preventive interventions achieve a dual aim. From a patient perspective, it may reduce the amount of emergency surgery or intervention, and inpatient stays. In addition, it slows disease progression, lowers lifestyle restrictions, reduces psychological stress, and improves health-related quality of life. Expert commentary: Early detection and preventive measures are likely to achieve a dual aim by simultaneously containing costs and reducing the number and length of inpatient stays.

Full Text Available Background: Mitral regurgitation is one of the leading causes of cardiovascular morbidity in pediatric patients with Marfan syndrome. The purpose of this study was to contribute to determining the appropriate surgical strategy for these patients. Methods: From January 1992 to May 2013, six patients with Marfan syndrome underwent surgery for mitral regurgitation in infancy or early childhood. Results: The median age at the time of surgery was 47 months (range, 3 to 140 months and the median follow-up period was 3.6 years (range, 1.3 to 15.5 years. Mitral valve repair was performed in two patients and four patients underwent mitral valve replacement with a mechanical prosthesis. There was one reoperation requiring valve replacement for aggravated mitral regurgitation two months after repair. The four patients who underwent mitral valve replacement did not experience any complications related to the prosthetic valve. One late death occurred due to progressive emphysema and tricuspid regurgitation. Conclusion: Although repair can be an option for some patients, it may not be durable in infantile-onset Marfan syndrome patients who require surgical management during infancy or childhood. Mitral valve replacement is a feasible treatment option for these patients.

This retrospective study attempted to establish the prevalence of multiple-valve involvement in Marfan syndrome and to compare echocardiographic with histopathologic findings in Marfan patients undergoing valvular or aortic surgery. We reviewed echocardiograms of 73 Marfan patients who underwent cardiovascular surgery from January 2004 through October 2009. Tissue histology was available for comparison in 29 patients. Among the 73 patients, 66 underwent aortic valve replacement or the Bentall procedure. Histologic findings were available in 29 patients, all of whom had myxomatous degeneration. Of 63 patients with moderate or severe aortic regurgitation as determined by echocardiography, 4 had thickened aortic valves. The echocardiographic findings in 18 patients with mitral involvement included mitral prolapse in 15. Of 11 patients with moderate or severe mitral regurgitation as determined by echocardiography, 4 underwent mitral valve repair and 7 mitral valve replacement. Histologic findings among mitral valve replacement patients showed thickened valve tissue and myxomatous degeneration. Tricuspid involvement was seen echocardiographically in 8 patients, all of whom had tricuspid prolapse. Two patients had severe tricuspid regurgitation, and both underwent repair. Both mitral and tricuspid involvement were seen echocardiographically in 7 patients. Among the 73 patients undergoing cardiac surgery for Marfan syndrome, 66 had moderate or severe aortic regurgitation, although their valves manifested few histologic changes. Eighteen patients had mitral involvement (moderate or severe mitral regurgitation, prolapse, or both), and 8 had tricuspid involvement. Mitral valves were most frequently found to have histologic changes, but the tricuspid valve was invariably involved.

Marfan syndrome patients present important cardiac structural changes, ventricular dysfunction, and electrocardiographic changes. An abnormal heart rate response during or after exercise is an independent predictor of mortality and autonomic dysfunction. The aim of the present study was to compare heart rate recovery and chronotropic response obtained by cardiac reserve in patients with Marfan syndrome subjected to submaximal exercise. A total of 12 patients on β-blocker therapy and 13 off β-blocker therapy were compared with 12 healthy controls. They were subjected to submaximal exercise with lactate measurements. The heart rate recovery was obtained in the first minute of recovery and corrected for cardiac reserve and peak lactate concentration. Peak heart rate (141±16 versus 155±17 versus 174±8 bpm; p=0.001), heart rate reserve (58.7±9.4 versus 67.6±14.3 versus 82.6±4.8 bpm; p=0.001), heart rate recovery (22±6 versus 22±8 versus 34±9 bpm; p=0.001), and heart rate recovery/lactate (3±1 versus 3±1 versus 5±1 bpm/mmol/L; p=0.003) were different between Marfan groups and controls, respectively. All the patients with Marfan syndrome had heart rate recovery values below the mean observed in the control group. The absolute values of heart rate recovery were strongly correlated with the heart rate reserve (r=0.76; p=0.001). Marfan syndrome patients have reduced heart rate recovery and chronotropic deficit after submaximal exercise, and the chronotropic deficit is a strong determinant of heart rate recovery. These changes are suggestive of autonomic dysfunction.

The clinical manifestations of Marfan syndrome frequently cause pain. This study aimed to characterize pain in a cohort of adults with Marfan syndrome and investigate demographic, physical, and psychological factors associated with pain and pain-related disability. Two hundred and forty-five participants (73% female, 89% non-Hispanic white, 90% North American) completed an online questionnaire assessing clinical features of Marfan syndrome, pain severity, pain-related disability, physical and mental health, depressive symptoms, pain catastrophizing, and insomnia. Eighty-nine percent of respondents reported having pain with 28% of individuals reporting pain as a presenting symptom of Marfan syndrome. Almost half of individuals reported that pain has spread from its initial site. Participants in our study reported poor physical and mental health functioning, moderate pain-related disability, and mild levels of depressive symptoms, sleep disturbances, and pain catastrophizing. Those who identified pain as an initial symptom of Marfan syndrome and those who reported that pain had spread from its initial site reported greater psychological burden compared with those without pain as an initial symptom or pain spreading. Physical health is the largest predictor of pain severity and pain-related disability. While pain catastrophizing and worse mental health functioning are significant correlates of pain severity and pain-related disability, respectively. Pain is a significant and persistent problem in Marfan syndrome and is associated with profound disability and psychological burden. Further studies are indicated to better characterize the directionality of pain, pain-related disability, and psychological burden in Marfan syndrome. © 2016 Wiley Periodicals, Inc. © 2016 Wiley Periodicals, Inc.

In many cardiac units, aortic valve-sparing operations have become the preferred surgical procedure to treat aortic root aneurysm in patients with Marfan syndrome, based on relatively short-term outcomes. This study examined the long-term outcomes of aortic valve-sparing operations in patients with Marfan syndrome. All patients with Marfan syndrome operated on for aortic root aneurysm from 1988 through 2012 were followed prospectively for a median of 10 years. Follow-up was 100% complete. Time-to-event analyses were calculated using the Kaplan-Meier method with log-rank test for comparisons. A total of 146 patients with Marfan syndrome had aortic valve-sparing operations. Reimplantation of the aortic valve was performed in 121 and remodeling of the aortic root was performed in 25 patients. Mean age was 35.7 ± 11.4 years and two-thirds were men. Nine patients had acute, 2 had chronic type A, and 3 had chronic type B aortic dissections before surgery. There were 1 operative and 6 late deaths, 5 caused by complications of dissections. Mortality rate at 15 years was 6.8 ± 2.9%, higher than the general population matched for age and sex. Five patients required reoperation on the aortic valve: 2 for endocarditis and 3 for aortic insufficiency. Three patients developed severe, 4 moderate, and 3 mild-to-moderate aortic insufficiency. Rate of aortic insufficiency at 15 years was 7.9 ± 3.3%, lower after reimplantation than remodeling. Nine patients developed new distal aortic dissections during follow-up. Rate of dissection at 15 years was 16.5 ± 3.4%. Aortic valve-sparing operations in patients with Marfan syndrome were associated with low rates of valve-related complications in long-term follow-up. Residual and new aortic dissections were the leading cause of death. Copyright © 2015 American College of Cardiology Foundation. Published by Elsevier Inc. All rights reserved.

Aortic aneurysm formation leading eventually to aortic rupture or dissection in early adult life is a fatal outcome of Marfan syndrome (MFS). Advances in the treatment of the syndrome have improved prognosis, but the long-term reoperation rate is still high. It remains unknown which factors influence the long-term prognosis, including the reoperation and mortality rates, in surgically treated Chinese patients with MFS. The authors studied 125 such patients to investigate factors influencing prognosis after aortic surgery. A retrospective clinical investigation. An academic medical center. One hundred twenty-five Marfan patients who had undergone aortic surgery. None. The indications for aortic surgery were aortic aneurysm and/or dissection in the 125 Marfan patients. The most commonly performed procedure was the Bentall in 92 patients. Sixteen patients underwent total arch replacement combined with stented elephant trunk implantation. Ten patients underwent the David procedure. Overall in-hospital and 30-day mortality rate was 1.6%. The survival rate was 97.5%, 91.4%, and 74.2% at 1, 5, and 10 years after surgery, respectively. The reoperation rate was 2.5%, 12.9%, and 32.9% at 1, 5, and 10 years after surgery, respectively. Multivariate analysis revealed that increased systolic blood pressure (Sys BP) was the predictor of death (p < 0.05), and body mass index and smoking were significant predictors of reoperation (p < 0.05). The present findings report the factors influencing the prognosis of Chinese patients with MFS after aortic surgical procedures. Managing these risk factors may enable health care professionals to improve the prognosis of MFS patients after aortic surgical procedures. Copyright © 2011 Elsevier Inc. All rights reserved.

The aim of this work is the investigation of measures of ambulatory brachial and aortic blood pressure and indices of arterial stiffness and aortic wave reflection in Marfan patients. A case-control study was conducted including patients with diagnosed Marfan syndrome following Ghent2 nosology and healthy controls matched for sex, age and daytime brachial systolic blood pressure. For each subject a 24 h ambulatory blood pressure and 24 h pulse wave analysis measurement was performed. All parameters showed a circadian pattern whereby pressure dipping was more pronounced in Marfan patients. During daytime only Marfan patients with aortic root surgery showed increased pulse wave velocity. In contrast, various nighttime measurements, wave reflection determinants and circadian patterns showed a significant difference. The findings of our study provide evidence that ambulatory measurement of arterial stiffness parameters is feasible and that these determinants are significantly different in Marfan syndrome patients compared to controls in particular at nighttime. Further investigation is therefore indicated.

Recent Clinical Drug Trials Evidence in Marfan Syndrome and Clinical Implications.

Singh, Michael N; Lacro, Ronald V

Marfan syndrome is a genetic disorder of connective tissue with principal manifestations in the cardiovascular, ocular, and skeletal systems. Cardiovascular disease, mainly progressive aortic root dilation and aortic dissection, is the leading cause of morbidity and mortality. The primary aims of this report were to examine the evidence related to medical therapy for Marfan syndrome, including recently completed randomized clinical trials on the efficacy of β-blockers and angiotensin II receptor blockers for the prophylactic treatment of aortic enlargement in Marfan syndrome, and to provide recommendations for medical therapy on the basis of available evidence. Medical therapy for Marfan syndrome should be individualized according to patient tolerance and risk factors such as age, aortic size, and family history of aortic dissection. The Pediatric Heart Network trial showed that atenolol and losartan each reduced the rate of aortic dilation. All patients with known or suspected Marfan syndrome and aortic root dilation should receive medical therapy with adequate doses of either β-blocker or angiotensin receptor blocker. The Pediatric Heart Network trial also showed that atenolol and losartan are more effective at reduction of aortic root z score in younger subjects, which suggests that medical therapy should be prescribed even in the youngest children with aortic dilation. For patients with Marfan syndrome without aortic dilation, the available evidence is less clear. If aortic dilation is severe and/or progressive, therapy with a combination of β-blocker and angiotensin receptor blocker should be considered, although trial results are mixed with respect to the efficacy of combination therapy vs monotherapy.

Preservation of the aortic valve using the technique described by David has been shown to be as effective as the Bentall-De Bono procedure. It avoids both the need for long-term anticoagulation and the complications associated with mechanical prostheses. We report our initial experience using this technique in patients with Marfan syndrome. Between April 2004 and April 2006, we used the David reimplantation technique in 40 patients with an aortic root aneurysm. Eighteen patients had Marfan syndrome. Their median age was 29 years (13-55 years). Echocardiography showed that the median diameter of the aortic sinus was 53 mm (46-59 mm). In 17 patients, aortic valve preservation was possible. No patient died during hospitalization and there were no significant complications. On echocardiography at discharge, no patient had greater than grade-II aortic regurgitation. During a median follow-up period of 8 months (1-24 months), one patient died due to rupture of an abdominal aneurysm. The others are all in New York Heart Association class I. Preservation of the aortic valve by means of valve reimplantation produced excellent results. It avoided both the thromboembolic and hemorrhagic complications associated with prostheses and the need for long-term anticoagulation. If reimplanted valves continue to function adequately over the long term, this technique should become the treatment of choice for aneurysms of the ascending aorta in patients with Marfan syndrome.

Losartan in combination with propranolol slows the aortic root dilatation in neonatal Marfan syndrome

Lu-Hang Liu

2018-04-01

Full Text Available Neonatal Marfan syndrome, in contrast to classical Marfan syndrome, is characterized by rapidly progressive multi-valvular cardiac disease and death from congestive heart failure, typically within the first year of life. Due to the rarity of this condition, treatment for neonatal Marfan syndrome has not been well studied. In this report, a combination of losartan and propranolol reduced the aortic root dilatation rate after three months of losartan therapy. Genetic analysis in this patient revealed a mutation in exon 25 of the FBN1 gene, which typically results in a shorter life expectancy. However, the patient's heart failure was controlled by losartan, propranolol and other anti-congestive medications, which may have prolonged his survival.

Marfan syndrome: clinical diagnosis and management.

Dean, John C S

2007-07-01

Marfan syndrome is a multisystem connective tissue disorder usually associated with mutation in fibrillin, and occasionally with mutation in TGFBR1 or 2. The clinical diagnosis is made using the Ghent nosology, which will unequivocally diagnose or exclude Marfan syndrome in 86% of cases. Use of a care pathway can help implementation of the nosology in the clinic. The penetrance of some features is age dependent, so the nosology must be used with caution in children. Molecular testing may be helpful in this context. The nosology cannot be used in families with isolated aortic dissection, or with related conditions such as Loeys-Dietz syndrome, although it may help identify families for further diagnostic evaluation because they do not fulfill the nosology, despite a history of aneurysm. Prophylactic medical (eg beta-blockade) and surgical intervention is important in reducing the cardiovascular complications of Marfan syndrome. Musculoskeletal symptoms are common, although the pathophysiology is less clear--for example, the correlation between dural ectasia and back pain is uncertain. Symptoms in other systems require specialist review such as ophthalmology assessment of refractive errors and ectopia lentis. Pregnancy is a time of increased cardiovascular risk for women with Marfan syndrome, particularly if the aortic root exceeds 4 cm at the start of pregnancy. High-intensity static exercise should be discouraged although low-moderate intensity dynamic exercise may be beneficial. The diagnosis and management of Marfan syndrome requires a multidisciplinary team approach, in view of its multisystem effects and phenotypic variability.

Patients with Marfan syndrome require repeated imaging for monitoring of aortic root aneurysms. Therefore, we evaluated the agreement and reproducibility of cine-MRI and echocardiography measurements of the sinuses of Valsalva in patients with suspected Marfan syndrome. 51 consecutive patients with suspected Marfan syndrome were prospectively examined using cine-MRI and echocardiography. Two readers independently measured aortic root diameters at the level of the sinuses of Valsalva in both cine-MRI and echocardiography. Statistics included intraclass correlation coefficient, Pearson correlation coefficient, Bland-Altman analysis, and two-sided t-test. In 38 of the 51 individuals (74.5 %), the diagnosis of Marfan syndrome was established according to the criteria of the Ghent-2 nosology. Cine-MRI measurements of the sinuses of Valsalva revealed a strong correlation with echocardiography (r=0.929), but a statistically significant bias of -1.0 mm (p<0.001). The mean absolute diameter for sinuses of Valsalva obtained by cine-MRI was 32.3 ± 5.8 mm as compared to 33.4 ± 5.4 mm obtained by echocardiography. Interobserver agreement of measurements of the sinuses of Valsalva was higher for cine-MRI than for echocardiography (p=0.029). Despite small, but statistically significant differences in terms of agreement and reproducibility, cine-MRI and echocardiographic measurements of aortic root diameters provide comparable results without a significant clinical difference. Therefore both techniques may be used for monitoring of the aortic root in patients with Marfan syndrome.

Engineered mutations in fibrillin-1 leading to Marfan syndrome act at the protein, cellular and organismal levels.

Science.gov (United States)

Zeyer, Karina A; Reinhardt, Dieter P

Fibrillins are the major components of microfibrils in the extracellular matrix of elastic and non-elastic tissues. They are multi-domain proteins, containing primarily calcium binding epidermal growth factor-like (cbEGF) domains and 8-cysteine/transforming growth factor-beta binding protein-like (TB) domains. Mutations in the fibrillin-1 gene give rise to Marfan syndrome, a connective tissue disorder with clinical complications in the cardiovascular, skeletal, ocular and other organ systems. Here, we review the consequences of engineered Marfan syndrome mutations in fibrillin-1 at the protein, cellular and organismal levels. Representative point mutations associated with Marfan syndrome in affected individuals have been introduced and analyzed in recombinant fibrillin-1 fragments. Those mutations affect fibrillin-1 on a structural and functional level. Mutations which impair folding of cbEGF domains can affect protein trafficking. Protein folding disrupted by some mutations can lead to defective secretion in mutant fibrillin-1 fragments, whereas fragments with other Marfan mutations are secreted normally. Many Marfan mutations render fibrillin-1 more susceptible to proteolysis. There is also evidence that some mutations affect heparin binding. Few mutations have been further analyzed in mouse models. An extensively studied mouse model of Marfan syndrome expresses mouse fibrillin-1 with a missense mutation (p.C1039G). The mice display similar characteristics to human patients with Marfan syndrome. Overall, the analyses of engineered mutations leading to Marfan syndrome provide important insights into the pathogenic molecular mechanisms exerted by mutated fibrillin-1.

Because diagnosis of Marfan syndrome is difficult during infancy, we used a large cohort of children to describe the evolution of the Marfan syndrome phenotype with age. Two hundred and fifty-nine children carrying an FBN1 gene mutation and fulfilling Ghent criteria were compared with 474 non-Marfan syndrome children. Prevalence of skeletal features changed with aging: prevalence of pectus deformity increased from 43% at 0-6 years to 62% at 15-17 years, wrist signs increased from 28 to 67%, and scoliosis increased from 16 to 59%. Hypermobility decreased from 67 to 47% and pes planus decreased from 73 to 65%. Striae increased from 2 to 84%. Prevalence of ectopia lentis remained stable, varying from 66 to 72%, similar to aortic root dilatation (varying from 75 to 80%). Aortic root dilatation remained stable during follow-up in this population receiving β-blocker therapy. When comparing Marfan syndrome children with non-Marfan syndrome children, height appeared to be a simple and discriminant criterion when it was >3.3 SD above the mean. Ectopia lentis and aortic dilatation were both similarly discriminating. Ectopia lentis and aortic dilatation are the best-discriminating features, but height remains a simple discriminating variable for general practitioners when >3.3 SD above the mean. Mean aortic dilatation remains stable in infancy when children receive a β-blocker.

Metacarpal index in Marfan's syndrome and in constitutional tall stature.

The metacarpal index (MCI) in 54 children with constitutional tall stature was mean (SD) 8.65 (0.8) and in 55 with Marfan's syndrome 9.15 (0.9). Indices in both groups showed arachnodactyly and differed from those found in normal individuals (< 7.9). Because the MCI is a poor discriminator patients with tall stature or clinical signs of arachnodactyly should be examined for additional signs of Marfan's syndrome or other hereditary disorders of connective tissue.

Full Text Available Marfan syndrome is an autosomal dominant disorder of the connective tissues, resulting in abnormalities of the musculoskeletal system, cardiovascular system and eyes. It has a prevalence of 1 in 100,000 population and occurs in all ethnic groups. It may be familial or due to new mutation (30%, in the fibrillin gene on arm of chromosome 15. It is estimated that one person in every 3000 to 5000 has Marfan′s syndrome may have cardiovascular abnormalities and may be complicated by infective endocarditis. About 90% of Marfan patients will develop cardiac complications.

Marfan syndrome is a hereditary disease with a prevalence of 2-3 in 10,000 births, leading to a fibrillin connective tissue disorder with manifestations in the skeleton, eye, skin, dura mater and in particular the cardiovascular system. Since other syndromes demonstrate similar vascular manifestations, but therapy may differ significantly, diagnosis should be established using the revised Ghent nosology in combination with genotypic analysis in specialized Marfan centres. The formation of aortic root aneurysms with the subsequent risk of acute aortic dissection type A (AADA) or aortic rupture limits life expectancy in patients with Marfan syndrome. Therefore, prophylactic replacement of the aortic root needs to be performed before the catastrophic event of AADA can occur. The goal of surgery is the complete resection of pathological aortic tissue. This can be achieved with excellent results by using a (mechanically) valved conduit that replaces both the aortic valve and the aortic root (Bentall operation). However, the need for lifelong anticoagulation with Coumadin can be avoided using the aortic valve sparing reimplantation technique according to David. The long-term durability of the reconstructed valve is favourable, and further technical improvements may improve longevity. Although results of prospective randomised long-term studies comparing surgical techniques are lacking, the David operation has become the surgical method of choice for aortic root aneurysms, not only at the Heidelberg Marfan Centre. Replacement of the aneurysmal dilated aortic arch is performed under moderate hypothermic circulatory arrest combined with antegrade cerebral perfusion using a heart-lung machine, which we also use in thoracic or thoracoabdominal aneurysms. Close post-operative follow-up in a Marfan centre is pivotal for the early detection of pathological changes on the diseased aorta.

The present study determines the effect of surgical treatment of cardiovascular manifestations of Marfan syndrome in 72 patients by 114 operations, during 34-year period. This therapy resulted in aortic root repair, aortic arch replacement, or both in 78, mitral valve repair in 9, descending thoracic aortic replacement in 14, thoracoabdominal aortic replacement in 10, and abdominal aortic replacement in 6, including total aortic replacement in 4 and nearly total aortic replacement in 4 patients. Fusiform aneurysms were present in the the ascending aorta in 37, the aortic arch in 2, the thoracoabdominal aorta in 2, and the abdominal aorta in 6 patients. Aortic dissection occurred in 40 (55.6%), including type A aortic dissection in 29 patients. Aortic root repair included separate valve-graft in 8, Bentall composite valve-graft in 25, composite valve-graft with button technique in 26, composite valve-graft with interposition graft technique in 10, and valve sparing procedure in 5 patients. The overall early (30-day) mortality was 7.9%. The early survival was 75% in separate valve-graft procedure and 99.2% in composite valve-graft procedure. Late coronary dehiscence did not occur in the patients with Bentall technique in which the reattachments of coronary ostia were performed in 2 layers, but occurred in 50% of patients with the coronary anastomoses in 1 layer. Aortic valve regurgitation relapsed in 2 of the 5 patients with valve sparing procedure. Event free rate for the patients with composite valve-graft using button technique was 81.1% at 10 years. There were 14 late deaths; dissection or rupture of the residual aorta, composite graft endocarditis and cardiac failure were the principle causes of late deaths. In conclusion, Marfan patients with cardiovascular diseases can undergo surgical treatment with a low operative risk and low morbidity. Although late endocarditis remains a serious problem, we believe that Marfan syndrome is a contraindication for valve

The Marfan syndrome is a systemic connective tissue disorder with autosomal dominant inheritance. A mutation of the fibrillin-1 gene, a glycoprotein which is the main constituent of the extracellular matrix, is the cause of the disease. The cardinal features involve the skeletal, ocular and cardiovascular systems. The expression of the Marfan syndrome varies from the severe neonatal presentation to the classical manifestations of the child and young adult, but also comprises isolated features. In children, phenotypical manifestations are age dependent. For these reasons, the diagnosis of Marfan syndrome might be lately revealed by its cardiovascular complications. We report the case of 2 siblings: it illustrates the phenotypic variability that might be observed in a same family, the phenotype evolution with age and the diagnosis challenge in childhood.

When treating dissecting aneurysm of the thoracoabdominal aorta surgically in patients with Marfan syndrome, we have usually performed graft replacement- including the entire thoracoabdominal aorta and reconstruction of all visceral branches, even if dilatation is mild in some segments-to avoid further aortic operations in the follow-up period. From October 1999 through July 2011, 20 consecutive patients with Marfan syndrome underwent repair of dissecting aneurysm of the thoracoabdominal aorta (median age, 45 years; range, 19-65 years). All patients underwent surgical intervention with cerebrospinal fluid (CSF) drainage and distal aortic and selective organ perfusion. Deep hypothermia was used in 13 patients for spinal cord protection. No in-hospital mortality was observed. One patient had temporary spinal cord ischemia but was fully recovered by discharge. Other complications included exploration for bleeding (n=1), prolonged ventilation (n=1), and graft infection (n=1). At a mean follow-up of 54 months (range, 9-129 months), 1 patient had died of interstitial pneumonia at 38 months postoperatively. Survival at 8% years was 91.2±9.0%. Two patients required additional aortic procedures (total arch replacement and aortic valve-sparing surgery). Actuarial rate of freedom from aortic operations at 8 years was 83.9%±10.5%, but no patient needed required repeated thoracotomy for an aortic procedure. Neither false nor patch aneurysms were observed using computed tomography (CT) during follow-up surveillance. Graft replacement for dissecting aneurysm of the thoracoabdominal aorta in Marfan syndrome offers good early and long-term results. We believe total aortic replacement including the entire thoracoabdominal aorta and reconstruction of all visceral arteries should be recommended for selected patients with Marfan syndrome.

Sex-related differences as well as the adverse effect of pregnancy on aortic disease outcome are well-established phenomena in humans with Marfan syndrome (MFS). The underlying mechanisms of these observations are largely unknown. In an initial (pilot) step we aimed to confirm the differences between male and female MFS patients as well as between females with and without previous pregnancy. We then sought to evaluate whether these findings are recapitulated in a pre-clinical model and performed in-depth cardiovascular phenotyping of mutant male and both nulliparous and multiparous female Marfan mice. The effect of 17β-estradiol on fibrillin-1 protein synthesis was compared in vitro using human aortic smooth muscle cells and fibroblasts. Our small retrospective study of aortic dimensions in a cohort of 10 men and 20 women with MFS (10 pregnant and 10 non-pregnant) confirmed that aortic root growth was significantly increased in the pregnant group compared to the non-pregnant group (0.64mm/year vs. 0.12mm/year, p = 0.018). Male MFS patients had significantly larger aortic root diameters compared to the non-pregnant and pregnant females at baseline and follow-up (p = 0.002 and p = 0.007, respectively), but no significant increase in aortic root growth was observed compared to the females after follow-up (p = 0.559 and p = 0.352). In the GT-8/+ MFS mouse model, multiparous female Marfan mice showed increased aortic diameters when compared to nulliparous females. Aortic dilatation in multiparous females was comparable to Marfan male mice. Moreover, increased aortic diameters were associated with more severe fragmentation of the elastic lamellae. In addition, 17β-estradiol was found to promote fibrillin-1 production by human aortic smooth muscle cells. Pregnancy-related changes influence aortic disease severity in otherwise protected female MFS mice and patients. There may be a role for estrogen in the female sex protective effect.

Twenty-five patients with Marfan, syndrome underwent both CT and MR imaging. MR imaging were interpreted in blinded fashion and then compared with CT scans MR imaging was found to be equivalent to CT in the detection of aortic, dural, and hip abnormalities in patients not operated on. MR imaging was superior to CT in the evaluation of postoperative patients because the artifact produced by Bjork-Shirley or St. Jude valves precludes adequate evaluation of the aortic root on CT while producing only a small inferior field distortion (a ''pseudo-ventricular septal defect'') on MR imaging. The absence of radiation exposure is another major advantage of MR imaging in this relatively young population requiring serial studies. The authors conclude that MR imaging is the modality of choice for the evaluation and follow-up of patients with Marfan syndrome and offers an appropriate means of screening their kindred

Marfan syndrome is an autosomal dominant genetic disorder caused by a connective tissue defect. A nine-year-old girl was referred to our pediatric endocrinology clinic for tall stature. Physical examination revealed a lens dislocation with strabismus, high palate, positive wrist and thumb signs, joint hypermobility, and pes planus. Transthoracic echocardiography revealed dilatation of the aortic root. She was diagnosed with Marfan syndrome based on the revised Ghent diagnostic criteria. Molecular investigation identified a heterozygous c.2810G >A variation in the FBN1 gene in the patient, but not in her parents. To our knowledge, this sequence variant has been reported as a polymorphism (rs113602180), but it is the first report identifying it as the genetic cause of Marfan syndrome. We hypothesize that this de novo novel missense FBN1 mutation disrupts fibrillin-1 function and is probably involved in the development of Marfan syndrome in this patient. © 2017 by the Association of Clinical Scientists, Inc.

Marfan syndrome is rarely diagnosed in the neonatal period because of variable expression and age-dependent appearance of clinical signs. The prognosis is usually poor due to high probability of congestive heart failure, mitral and tricuspid regurgitations with suboptimal response to medical therapy and difficulties in surgical management. The authors have studied two cases of Marfan syndrome in the newborn period. Two cases of neonatal Marfan syndrome, one male and one female, were diagnosed by characteristic physical appearance. Both infants had significant cardiovascular abnormalities diagnosed by ultrasonography. Genetic DNA analysis in the second case confirmed the mutations in the fibrillin-1 gene located on chromosome 15q21 which is responsible for the development of Marfan syndrome. The boy died at six weeks of age with signs of rapidly progressive left ventricular failure associated with pneumonia. The second infant was having only mild signs of congestive heart failure and has been treated with beta blockers. At the age of 4 years her symptoms of congestive heart failure had worsened due to progression of mitral and tricuspid insufficiency and development of significant cardiomegaly. Mitral and tricuspid valvuloplasy had to be done at that time. Early diagnosis of Marfan syndrome in the newborn period can allow treatment in the early stages of cardiovascular abnormalities and may improve the prognosis. It also helps to explain to the family the serious health problem of their child.

We reviewed our experience with aortic valve-sparing operations in Marfan syndrome during last 5 years. Between March 2004 and June 2009, 94 patients with aortic root aneurysms underwent valve-sparing operations. Of these, 37 (68% male) were diagnosed with Marfan syndrome, according to the Ghent diagnostic criteria. Mean age was 30 +/- 10 years (range, 11 to 59 years). Moderate/severe aortic regurgitation was present in 13%, and the mean diameter of the Valsalva sinuses was 50 +/- 4 mm (range, 42 to 62 mm). The David V modification was performed in the last 28 patients. Additional procedures were mitral valve repair in 6, tricuspid valve repair in 3, closure of septal atrial defect in 2, and closure of a patent foramen ovale in 13. Mean follow-up was 27 +/- 16 months (range, 1 to 61 months). There were no in-hospital deaths and no major adverse outcomes. One patient required implantation of a mechanical prosthesis during the same procedure because of moderate aortic regurgitation. One late death occurred. No patients required reoperation. In the last follow-up, 23 patients did not have aortic regurgitation, 12 had grade I, and 1 had grade II. No thromboembolic complications have been documented, and 97% of the patients are free from anticoagulation. Short-term and midterm results with the reimplantation technique for aortic root aneurysms in Marfan patients are excellent. If long-term results are similar, this technique could be the treatment of choice for these patients. 2010 The Society of Thoracic Surgeons. Published by Elsevier Inc. All rights reserved.

Pseudoaneurysms of the ascending aorta after the original inclusion/wrap technique of the Bentall procedure present a difficult surgical management problem and are associated with substantial morbidity and mortality. Patients with Marfan syndrome frequently develop aneurysms and dissections that involve multiple aortic segments. We present the case of a Marfan patient who successfully underwent repair of a giant ascending aortic pseudoaneurysm and concomitant repair of an abdominal aortic aneurysm. An aggressive surgical strategy followed by life-long cardiovascular monitoring is warranted in order to prolong the survival of these patients. (Tex Heart Inst J 2003;30:233–5) PMID:12959210

Doctor Antoine Marfan described the first case of Marfan syndrome in 1896. It was over 50 years later that the development of aortic aneurysms and subsequent rupture was appreciated as the most life-threatening component of the syndrome. Doctor Vincent Gott, at our institution, performed the first Bentall procedure for an aneurysm of the ascending aorta in 1976. Since that time, the aortic root has been replaced in 231 Marfan patients. Of this group, 218 patients had a composite graft repair, 11 had an aortic root replacement with a homograft, and 2 patients had valve sparing procedures. There were 168 males and 63 females. Of the total 231 patients, 150 were operated on by Dr Gott. The remaining 81 patients were operated on by 10 other Hopkins surgeons. The average diameter of the ascending aorta was 6.8 cm, with a range from 4.5 to 10. The average aortic diameter of 43 patients who had an ascending aortic dissection was 7.3 cm. Fourteen of these patients had dissection with an aortic diameter of 6.5 cm or less. Among the 198 patients who underwent elective repair, there was no 30-day mortality. Thirty-three patients underwent urgent repair with 2 deaths, yielding a 30-day mortality of 6.1%. The mortality for the entire group of patients was 0.9%. Complications associated with this series of patients included 8 with endocarditis, 7 with thromboembolism, and 4 late coronary dehiscences. Actuarial survival was 88% at 5 years, 81% at 10 years, and 75% at 20 years. Multivariate analysis revealed New York Heart Association classification, male gender and urgent surgery as independent risk factors for mortality. Marfan patients with aortic aneurysms can undergo elective surgery with a low operative risk and excellent long-term survival with low morbidity. We feel that elective resection of an aneurysm in a Marfan patient should occur when it approaches a diameter of 5.5 cm. It is essential that a timely diagnosis be made in this group of young patients.

To evaluate corneal air-puff deformation responses and ocular geometry as predictors of Marfan syndrome. Prospective observational clinical study. Sixteen investigator-derived, 4 standard Ocular Response Analyzer (ORA), and geometric variables from corneal tomography and optical biometry using Oculus Pentacam and IOL Master were assessed for discriminative value in Marfan syndrome, measuring right eyes of 24 control and 13 Marfan syndrome subjects. Area under the receiver operating characteristic (AUROC) curve was assessed in univariate and multivariate analyses. Six investigator-derived ORA variables successfully discriminated Marfan syndrome. The best lone disease predictor was Concavity Min (Marfan syndrome 47.5 ± 20, control 69 ± 14, P = .003; AUROC = 0.80). Corneal hysteresis (CH) and corneal resistance factor (CRF) were decreased (Marfan syndrome CH 9.45 ± 1.62, control CH 11.24 ± 1.21, P = .01; Marfan syndrome CRF 9.77 ± 1.65, control CRF 11.03 ± 1.72, P = .01) and corneas were flatter in Marfan syndrome (Marfan syndrome Kmean 41.25 ± 2.09 diopter, control Kmean 42.70 ± 1.81 diopter, P = .046). No significant differences were observed in central corneal thickness, axial eye length, or intraocular pressure. A multivariate regression model incorporating corneal curvature and hysteresis loop area (HLA) provided the best predictive value for Marfan syndrome (AUROC = 0.85). This study describes novel biodynamic features of corneal deformation responses in Marfan syndrome, including increased deformation, decreased bending resistance, and decreased energy dissipation capacity. A predictive model incorporating HLA and corneal curvature shows greatest potential for noninvasive clinical diagnosis of Marfan syndrome. Copyright © 2016 Elsevier Inc. All rights reserved.

Marfan syndrome is an autosomal dominant genetic disorder characterized by an abnormal fibrillin-1 synthesis. Aortic root dilation and dissection are the main problems affecting patients prognosis in these patients. Their pharmacological prophylaxis with losartan or with a beta-blocker counteracts the aortic root dilation, but a close follow-up is required to assess therapeutic response rate and to identify non-responders. Unfortunately genotype-phenotype studies do not allow to determine the exact risk profile in these patients and there is no reliable method to accurately predict their risk of aortic dissection. Aim of this study was to evaluate non-invasive markers for identification of Marfan patients at higher risk of aortic complications. We studied 187 Marfan patients (identified according to 2010 Revised Ghent Criteria and positive genetic analysis), age 32.3 ± 16.5 yrs (mean ± SD). 52 patients (27.8%) had undergone surgical ascending aorta replacement (David or Bentall procedure). Central pressure curves were recorded by PulsePen tonometer, and the aortic viscoelastic aortic properties were studied by determination of carotid-femoral pulse wave velocity (PWV). With reference to the age related distribution of PWV values in a normal population, defined according to Arterial-Stiffness-Collaboration, PWV mean values in Marfan patients corresponded to 60th percentile in non- operated patients and to the 67th percentile in those operated. Adult Marfan patients (n = 146) generally displayed a low blood pressure, because of the pharmacological prophylaxis, and were compared with a population of 189 adult healthy subjects (81 males), matched by age (38 ± 13 vs 38 ± 16 yrs.), heart rate (64 ± 9 bpm vs 64 ± 11 bpm) and blood pressure (mean BP = 78 ± 9 mmHg vs 79 ± 4 mmHg) values. Average PWV value was higher than in healthy controls (PWV = 7.0 ± 1.7) both in not operated (PWV = 7.6 ± 1.6; p = 0

There is no study concerning safety and accuracy of pedicle screw placement in Marfan syndrome. The objective of this study is to investigate accuracy and safety of pedicle screw placement in scoliosis associated with Marfan syndrome. CT scanning was performed to analyze accuracy of pedicle screw placement. Pedicle perforations were classified as medial, lateral or anterior and categorized to four grades: ≤ 2 mm as Grade 1, 2.1-4.0 mm as Grade 2, 4.1-6.0 mm as Grade 3, ≥6.1 mm as Grade 4. Fully contained screws or with medial wall perforation ≤ 2 mm or with lateral wall perforation ≤ 6 mm and without injury of visceral organs were considered acceptable, otherwise were unacceptable. 976 pedicle screws were placed, 713 screws (73.1%) were fully contained within the cortical boundaries of the pedicle. 924 (94.7%) screws were considered as acceptable, and 52 (5.3%) as unacceptable. The perforation rate was higher using free-hand technique than O-arm navigation technique (30.8% VS. 11.4%, P Marfan syndrome is accuracy and safe. O-arm navigation was an effective modality to ensure the safety and accuracy of screw placement. Special attention should be paid when screws were placed at the lumber spine and the concave side of spine deformity to avoid the higher rate of complications.

Marfan syndrome is a connective-tissue disorder affecting cardiovascular, skeletal, and ocular systems. The major Marfan locus has been identified as the FBN1 gene on chromosome 15; this codes for the extracellular-matrix protein fibrillin, a 350-kD constituent of the 8-10-nm elastin-associated microfibrils. The authors identified five MFS patients who were heterozygous for an RsaI restriction-site dimorphism in the 3{prime} UTR of the FBN1 gene. This expressed variation was used to distinguish the mRNA output from each of the two FBN1 alleles in fibroblast cultures from these five patients. Three of the patients were shown to produce <5% of the normal level of FBN1 transcripts from one of their alleles. This null-allele phenotype was not observed in 10 nonmarfanoid fibroblast cell lines. 26 refs., 4 figs.

In 1896, in the Bulletin of the Medical Society of Paris, Antoine Marfan described a five-year-old girl with arachnodactyly. It took almost 50 years to fully elucidate this syndrome including aneurysm of the ascending aorta. It is critical to make an early diagnosis of Marfan aneurysm because there is a high frequency of dissection and rupture once the aortic diameter reaches 6 cm. Before the availability of the Bentall composite graft procedure in 1968, the operative results were very poor. The Bentall operation now carries a 30-day mortality rate of less than 5% at major cardiac surgical centers. Two hundred and thirty-one Marfan patients underwent aortic root replacement at The Johns Hopkins Hospital between September 1976 and December 1997. The 30-day mortality for 198 patients undergoing elective aortic root replacement was 0%. Two of 33 patients undergoing urgent surgery died in the first 30 days after surgery; both of these patients arrived in the operating room with ruptured aortas. The actuarial survival for the 231 patients undergoing aortic root replacement was 88% at five years, 81% at ten years, and 75% at 20 years. Clearly, the outlook for Marfan patients undergoing elective aortic root replacement has been excellent. Accompanying the steadily improving surgical results have been spectacular developments in understanding the genetic role in Marfan families. Since 1991, over 150 mutations have been discovered in the gene that is critical in the production of the structural protein fibrillin. The identification of mutations in the fibrillin gene has enabled the diagnosis of Marfan disease in some patients before they become symptomatic; prenatal diagnosis has been achieved in some patients. The ultimate hope for Marfan families is to eliminate the disease by genetic manipulation; however, this may be years away.

This study evaluated the efficacy of a stepwise regimen of estradiol valerate for height control in girls with Marfan syndrome. Eight girls with Marfan syndrome who had completed estrogen treatment for height control were included. Estradiol valerate was started at a dose of 2 mg/day, and then was increased. The projected final height was estimated using the initial height percentile (on a disease-specific growth curve for Korean Marfan syndrome [gcPFHt]), and the initial bone age (baPFHt). After the estrogen treatment, the projected final height was compared to the actual final height (FHt). The median baseline chronological and bone age were 10.0 and 10.5 years, respectively. After a median of 36.5 months of treatment, the median FHt (172.6 cm) was shorter than the median gcPFHt (181.0 cm) and baPFHt (175.9 cm). In the six patients who started treatment before the age of 11 years, the median FHt (171.8 cm) was shorter than the median gcPFHt (181.5 cm) and baPFHt (177.4 cm) after treatment. The median differences between the FHt and gcPFHt and baPFHt were 9.2 and 8.3 cm, respectively. In two patients started treatment after the age of 11, the differences between FHt and gcPFHt, and baPFHt after treatment were -4 and 1.4 cm, and -1.2 and 0 cm for each case, respectively. A stepwise increasing regimen of estradiol valerate may be an effective treatment for height control in girls with Marfan syndrome, especially when started under 11 years old.

Marfan syndrome is characterized by aortic root dilation, beginning in childhood. Data about aortic pulsatile hemodynamics and stiffness in pediatric age are currently lacking. In 51 young patients with Marfan syndrome (12.0±3.3 years), carotid tonometry was performed for the measurement of central pulse pressure, pulse pressure amplification, and aortic stiffness (carotid-femoral pulse wave velocity). Patients underwent an echocardiogram at baseline and at 1 year follow-up and a genetic evaluation. Pathogenetic fibrillin-1 mutations were classified between "dominant negative" and "haploinsufficient." The hemodynamic parameters of patients were compared with those of 80 sex, age, blood pressure, and heart-rate matched controls. Central pulse pressure was significantly higher (38.3±12.3 versus 33.6±7.8 mm Hg; P =0.009), and pulse pressure amplification was significantly reduced in Marfan than controls (17.9±15.3% versus 32.3±17.4%; P Marfan and controls (4.98±1.00 versus 4.75±0.67 m/s). In the Marfan group, central pulse pressure and pulse pressure amplification were independently associated with aortic diameter at the sinuses of Valsalva (respectively, β=0.371, P =0.010; β=-0.271, P =0.026). No significant difference in hemodynamic parameters was found according to fibrillin-1 genotype. Patients who increased aortic Z-scores at 1-year follow-up presented a higher central pulse pressure than the remaining (42.7±14.2 versus 32.3±5.9 mm Hg; P =0.004). Central pulse pressure and pulse pressure amplification were impaired in pediatric Marfan syndrome, and associated with aortic root diameters, whereas aortic pulse wave velocity was similar to that of a general pediatric population. An increased central pulse pressure was present among patients whose aortic dilatation worsened at 1-year follow-up. © 2017 The Authors.

Neonatal Marfan syndrome, in contrast to classical Marfan syndrome, is characterized by rapidly progressive multi-valvular cardiac disease and death from congestive heart failure, typically within the first year of life. Due to the rarity of this condition, treatment for neonatal Marfan syndrome has not been well studied. In this report, a combination of losartan and propranolol reduced the aortic root dilatation rate after three months of losartan therapy. Genetic analysis in this patient revealed a mutation in exon 25 of the FBN1 gene, which typically results in a shorter life expectancy. However, the patient's heart failure was controlled by losartan, propranolol and other anti-congestive medications, which may have prolonged his survival. Copyright © 2017.

Marfan syndrome commonly affects the skeletal, ocular, and cardiovascular systems. Involvement of the gastrointestinal system is known but uncommon. Intervention depends upon the system involved and the severity of symptoms. Special awareness is required for the diagnosis and management of gastrointestinal involvement in these patients. We report a rare case of simultaneous surgical repair of an ascending aortic aneurysm and a type IV hiatal hernia in a 35-year-old man with Marfan syndrome.

In a mouse model of Marfan syndrome, conventional Verhoeff-Van Gieson staining displays severe fragmentation, disorganization and loss of the aortic elastic fiber integrity. However, this method involves chemical fixatives and staining, which may alter the native morphology of elastin and collagen. Thus far, quantitative analysis of fiber damage in aorta and skin in Marfan syndrome has not yet been explored. In this study, we have used an advanced noninvasive and label-free imaging technique, multiphoton microscopy to quantify fiber fragmentation, disorganization, and total volumetric density of aortic and cutaneous elastin and collagen in a mouse model of Marfan syndrome. Aorta and skin samples were harvested from Marfan and control mice aged 3-, 6- and 9-month. Elastin and collagen were identified based on two-photon excitation fluorescence and second-harmonic-generation signals, respectively, without exogenous label. Measurement of fiber length indicated significant fragmentation in Marfan vs. control. Fast Fourier transform algorithm analysis demonstrated markedly lower fiber organization in Marfan mice. Significantly reduced volumetric density of elastin and collagen and thinner skin dermis were observed in Marfan mice. Cutaneous content of elastic fibers and thickness of dermis in 3-month Marfan resembled those in the oldest control mice. Our findings of early signs of fiber degradation and thinning of skin dermis support the potential development of a novel non-invasive approach for early diagnosis of Marfan syndrome.

We undertook a retrospective study of the pattern of reoperations in surgical patients with Marfan disease. Between 1985 and 2008, 83 Marfan patients (60 males, 23 females) underwent 155 aortic operations in our institution. Twenty-eight patients had acute dissection (22 type A, 6 type B), and two had aortic rupture. Mean age at initial operation was 32±13 years. Operations included valve-sparing or Bentall aortic root repair, and ascending aorta, arch, descending thoracic, thoracoabdominal aorta, and infrarenal aortic replacement. Sixty-one patients whose initial operation was elective (Group I) were compared with 22 patients with initial emergency surgery (Group II). Overall, 81/83 patients ultimately underwent root/ascending repair: 64% initially and 36% at reoperation. Operative mortality in Group I was 1.6% for both initial operations and reoperations vs 9.0% and 0% in Group II. Significant differences between Group I and Group II patients included: total reoperations (1 vs 3, p=0.05); arch operations (0 vs 1, p=0.003); descending thoracic aortic operations (0 vs 0.5, p=0.003); and total aortic segments replaced (1.6±1.0 vs 2.4±1.1, p=0.001). Survival at 5 and 10 years did not differ between Group I and II patients (87% and 71% vs 82% and 56%, p=0.19). Although reoperation occurs in about half of surgical Marfan patients, reoperative mortality is low. Patients with initial elective procedures fare better than those with initial emergency surgery: they have fewer subsequent operations, fewer aortic segments replaced, and trend toward improved survival. Elective root replacement should be seriously considered in any Marfan patient with significant root dilatation. Copyright © 2012 The Society of Thoracic Surgeons. Published by Elsevier Inc.

Marfan syndrome is an autosomal dominant disorder of connective tissue caused by mutations in the gene encoding fibrillin-1 (FBN1), a matrix component of microfibrils. Dural ectasia, i.e. enlargement of the neural canal mainly located in the lower lumbar and sacral region, frequently occurs in Marfan patients. The aim of our study was to investigate the role of dural ectasia in raising the diagnosis of Marfan syndrome and its association with FBN1 mutations. We studied 40 unrelated patients suspected for MFS, who underwent magnetic resonance imaging searching for dural ectasia. In all of them FBN1 gene analysis was also performed. Thirty-seven patients resulted affected by Marfan syndrome according to the '96 Ghent criteria; in 30 of them the diagnosis was confirmed when revaluated by the recently revised criteria (2010). Thirty-six patients resulted positive for dural ectasia. The degree of dural ectasia was grade 1 in 19 patients, grade 2 in 11 patients, and grade 3 in 6 patients. In 7 (24%) patients, the presence of dural ectasia allowed to reach a positive score for systemic feature criterion. Twenty-four patients carried an FBN1 mutation, that were represented by 13 missense (54%), and 11 (46%) mutations generating a premature termination codon (PTC, frameshifts and stop codons). No mutation was detected in the remaining 16 (6 patients with MFS and 10 with related disorders according to revised Ghent criteria). The prevalence of severe (grade 2 and grade 3) involvement of dura mater was higher in patients harbouring premature termination codon (PTC) mutations than those carrying missense-mutations (8/11 vs 2/13, P = 0.0111). Our data emphasizes the importance of dural ectasia screening to reach the diagnosis of Marfan syndrome especially when it is uncertain and indicates an association between PTC mutations and severe dural ectasia in Marfan patients.

Calcium channel blockers (CCBs) are prescribed to patients with Marfan syndrome for prophylaxis against aortic aneurysm progression, despite limited evidence for their efficacy and safety in the disorder. Unexpectedly, Marfan mice treated with CCBs show accelerated aneurysm expansion, rupture, and premature lethality. This effect is both extracellular signal-regulated kinase (ERK1/2) dependent and angiotensin-II type 1 receptor (AT1R) dependent. We have identified protein kinase C beta (PKCβ) as a critical mediator of this pathway and demonstrate that the PKCβ inhibitor enzastaurin, and the clinically available anti-hypertensive agent hydralazine, both normalize aortic growth in Marfan mice, in association with reduced PKCβ and ERK1/2 activation. Furthermore, patients with Marfan syndrome and other forms of inherited thoracic aortic aneurysm taking CCBs display increased risk of aortic dissection and need for aortic surgery, compared to patients on other antihypertensive agents.

The study objective was to evaluate patients with Marfan syndrome and mitral valve regurgitation undergoing valve repair or replacement and to compare them with patients undergoing repair for myxomatous mitral valve disease. We reviewed the medical records of consecutive patients with Marfan syndrome treated surgically between March 17, 1960, and September 12, 2011, for mitral regurgitation and performed a subanalysis of those with repairs compared with case-matched patients with myxomatous mitral valve disease who had repairs (March 14, 1995, to July 5, 2013). Of 61 consecutive patients, 40 underwent mitral repair and 21 underwent mitral replacement (mean [standard deviation] age, 40 [18] vs 31 [19] years; P = .09). Concomitant aortic surgery was performed to a similar extent (repair, 45% [18/40] vs replacement, 43% [9/21]; P = .87). Ten-year survival was significantly better in patients with Marfan syndrome with mitral repair than in those with replacement (80% vs 41%; P = .01). Mitral reintervention did not differ between mitral repair and replacement (cumulative risk of reoperation, 27% vs 15%; P = .64). In the matched cohort, 10-year survival after repair was similar for patients with Marfan syndrome and myxomatous mitral disease (84% vs 78%; P = .63), as was cumulative risk of reoperation (17% vs 12%; P = .61). Patients with Marfan syndrome and mitral regurgitation have better survival with repair than with replacement. Survival and risk of reoperation for patients with Marfan syndrome were similar to those for patients with myxomatous mitral disease. These results support the use of mitral valve repair in patients with Marfan syndrome and moderate or more mitral regurgitation, including those having composite replacement of the aortic root.

The acronym LEOPARD stands for a syndromic association of Lentigines, Eletrocardiographic changes, Ocular hypertelorism, Pulmonic stenosis, Abnormal genitalia, Retardation of growth and sensorineural Deafness. Inheritance is autosomal dominant with high penetrance and variable expressivity. In 1990 Torok et al. reported on the association of LEOPARD and Marfan syndrome. In addition a clinical similarity (cardiac and cutaneous involvement) exists with the Watson syndrome (neurofibromatosis and pulmonic stenosis) which is linked to the marker D17S33 on chromosome 17. We studied possible linkage of LEOPARD syndrome to the Marfan syndrome locus on chromosome 15 (D15S1, MF13, and (TAAAA)n repeats) and to the NF-1 locus on chromosome 17 in a family with 9 cases of LEOPARD syndrome. Close linkage between LEOPARD syndrome and both the Marfan locus on chromosome 15 and the NF-1 locus on chromosome 17 was excluded (lod score <-2.0 through {theta} = 0.1).

Full Text Available Marfan syndrome (MFS is an autosomal dominant disorder of connective tissue, while Duane retraction syndrome (DRS is a congenital cranial dysinnervation disorder (CCDD which can be transmitted as autosomal dominant disorder in 5–10% of patients. In this paper, we present an 8-year-old girl who presented with left eye DRS and bilateral subluxation of the lens associated with MFS in absence of familial involvement. To our knowledge this is the first case report of DRS with MFS. The occurrence of these syndromes together is very rare and appears to be coincidental.

The translational path from pharmacological insight to effective therapy can be a long one. We aim to describe the management of Marfan syndrome as a case-example of how pharmacological and genomic insights can contribute to improved therapy. We undertook a literature search for studies of Marfan syndrome, to identify milestones in description, understanding and therapy of the syndrome. From the studies retrieved we then weaved an evidence-based description of progress. Marfan syndrome shows considerable heterogeneity in clinical presentation. It relies on defined clinical criteria with confirmation based on FBN1 mutation testing. Surgical advances have prolonged life in Marfan syndrome. First-line prophylaxis of complications with β-adrenoceptor blockers became established on the basis that reduction of aortic pressure and heart rate would help. Over-activity of proteinases, first suggested in 1980, has since been confirmed by evidence of over-expression of matrix metalloproteinases (MMP), notably MMP-2 and MMP-9. The search for MMP inhibitors led to the evaluation of doxycycline, and both animal studies and small trials, provided early evidence that this widely used antimicrobial agent was useful. Identification of the importance of TGF-β led to evaluation of angiotensin II type I receptor (AT1R) blockers with highly promising results. Combination prophylactic therapy would appear rational. Pharmacological and genomic research has provided good evidence that therapy with losartan and doxycycline would prevent the aortic complications of Marfan syndrome. If on-going well designed trials confirm their efficacy, the outlook for Marfan syndrome patients would be improved considerably. PMID:21276043

Regular low-impact physical activity is generally allowed in patients with Marfan syndrome, a connective tissue disorder caused by heterozygous mutations in the fibrillin-1 gene. However, being above average in height encourages young adults with this syndrome to engage in high-intensity contact sports, which unfortunately increases the risk for aortic aneurysm and rupture, the leading cause of death in Marfan syndrome. In this study, we investigated the effects of voluntary (cage-wheel) or forced (treadmill) aerobic exercise at different intensities on aortic function and structure in a mouse model of Marfan syndrome. Four-week-old Marfan and wild-type mice were subjected to voluntary and forced exercise regimens or sedentary lifestyle for 5 mo. Thoracic aortic tissue was isolated and subjected to structural and functional studies. Our data showed that exercise improved aortic wall structure and function in Marfan mice and that the beneficial effect was biphasic, with an optimum at low intensity exercise (55-65% V̇o 2max ) and tapering off at a higher intensity of exercise (85% V̇o 2max ). The mechanism underlying the reduced elastin fragmentation in Marfan mice involved reduction of the expression of matrix metalloproteinases 2 and 9 within the aortic wall. These findings present the first evidence of potential beneficial effects of mild exercise on the structural integrity of the aortic wall in Marfan syndrome associated aneurysm. Our finding that moderate, but not strenuous, exercise protects aortic structure and function in a mouse model of Marfan syndrome could have important implications for the medical care of young Marfan patients. NEW & NOTEWORTHY The present study provides conclusive scientific evidence that daily exercise can improve aortic health in a mouse model of Marfan syndrome associated aortic aneurysm, and it establishes the threshold for the exercise intensity beyond which exercise may not be as protective. These findings establish a platform

Prophylactic aortic root replacement improves survival in patients with Marfan syndrome with aortic root aneurysms, but the optimal procedure remains undefined. Adult patients with Marfan syndrome who had Bentall or aortic valve-sparing root replacement (VSRR) procedures between 1997 and 2013 were identified. Comprehensive follow-up information was obtained from hospital charts and telephone contact. One hundred sixty-five adult patients with Marfan syndrome (aged > 20 years) had either VSRR (n = 98; 69 reimplantation, 29 remodeling) or Bentall (n = 67) procedures. Patients undergoing Bentall procedure were older (median, 37 vs 36 years; P = .03), had larger median preoperative sinus diameter (5.5 cm vs 5.0 cm; P = .003), more aortic dissections (25.4% vs 4.1%; P Marfan syndrome, patients undergoing Bentall and valve-sparing procedures have similar late survival, freedom from root reoperation, and freedom from endocarditis. However, valve-sparing procedures result in significantly fewer thromboembolic and hemorrhagic events. Copyright © 2016 The American Association for Thoracic Surgery. Published by Elsevier Inc.

No patients died in the initial operation. Fate of false lumen on the stent graft border was expressed by CT scan follow-up that were patent in 0, thrombosis in 5 and absorption in 3 patients. One patient who had new aortic dissection 8 years after initial surgery required the Crawford V operation. Ten-years-survival rate was 100% and ten years-event free rate was 67%. Frozen elephant trunk technique was feasible for Marfan syndrome with acute aortic dissection and might become alternative prophylactic treatment to the downstream aorta for acute aortic dissection.

BACKGROUND: Patients with Marfan syndrome characteristically have an asthenic body habitus and are considered to be exempt from the obesity epidemic. OBJECTIVE: To examine the prevalence and clinical impact of obesity in a cohort of adults with Marfan syndrome. METHODS: Fifty outpatients (30 female) with a mean (± SD) age of 38±13 years were studied. Demographic variables including previously identified risk factors for aortic dissection were recorded. Body mass index (BMI) was determined and patients were classified as normal (BMI less than 25 kg/m2), overweight (BMI 25 kg/m2 to 29.9 kg/m2) or obese (BMI 30 kg/m2 or greater). Other cardiovascular risk factors were examined. An adverse clinical outcome was defined as either the attainment of surgical criteria for aortic root replacement or the presence of aortic dissection. RESULTS: A family history of aortic dissection was present in 13 (26%) patients. In 23 (46%) patients, there was no known family history of Marfan syndrome. Mean BMI was 25.4±7.4 kg/m2, with 18 (36%) patients having an elevated BMI. Positive smoking status was present in 15 (30%), hypertension in 13 (26%) and hyperlipidemia in 19 (38%) patients. Adverse clinical outcome was present in 27 (54%) patients. Logistic regression analysis revealed only index case (OR 44; PMarfan syndrome and is associated with an increased risk of aortic complications. PMID:20386774

To review our experience with crystalline lens extraction and iris claw Artisan IOL implantation in patients with lens subluxation secondary to Marfan syndrome. A retrospective analysis of 12 eyes of 9 patients with lens subluxation due to Marfan syndrome who underwent crystalline lens removal and Artisan IOL (Ophtec, Groningen, Netherlands) implantation. A questionnaire of pre- and post-operative data, including demographics, pre- and postoperative comorbidities and complications was completed. Patients were evaluated for visual outcome and occurrence of complications. Uncorrected visual acuity (UCVA), best-corrected visual acuity (BCVA), and spherical equivalents (SE) were compared before and after lens extraction and IOL insertion. The mean age of the participants was 30.03 ± 15.02 years, and mean post-operative follow-up time was 44.5 ± 16.4 months. Mean BCVA also showed a significant improvement from 0.5 ± 0.3 at the baseline to 0.2 ± 0.2 post-operatively (P = 0.006). SE changed significantly from -11.38 ± 1.99 preoperatively to -0.45 ± 1.65 post-operatively (P = 0.003). All eyes had the IOL implanted at desired position. Post-operative complications were retinal detachment in one case and IOL dislocation in another patient. No other complication such as ocular hypertension, angle abnormalities, clinical cystoids macular edema, and corneal decompensation was observed during the follow-up period. Artisan IOL implantation after lens extraction appears to be an attractive alternative for optical correction in cases of Marfan syndrome with ectopia lentis. It confers a significant improvement in visual acuity with reasonable risk profile.

The cardiovascular manifestation with aortic root dilatation, aortic valve regurgitation, and aortic dissection has a prevalence of 60% to 90% and determines the premature death of these patients. Thirty-four percent of the patients with Marfan syndrome will have serious cardiovascular complications requiring surgery in the first 10 years after diagnosis. Before aortic surgery became available, the majority of the patients died by the age of 32 years. Introduction in the aortic surgery techniques caused an increase of the 10 year survival rate up to 97%. The purpose of this article is to give an overview about the feasibility and outcome of stent-graft placement in the descending thoracic aorta in Marfan patients with previous aortic surgery.Keywords: Marfan syndrome, aortic dissection, root replacement, stent-graft, previous aortic surgery

We have previously described the experience, rationale, and development of a valve preserving technique, but its role in patients with Marfan syndrome has not previously been defined. Here, we attempt to determine the early and long-term results, timing, and determinants of outcome of this operation in patients with Marfan syndrome. Since 1979, 82 patients (73.2% of all patients with Marfan syndrome undergoing resection of aneurysm of the ascending aorta) were operated on using this technique. Ages ranged from 2 to 69 years (mean, 33.9 years). In all, there were 4 early deaths (4.9%), 2 with acute dissection and 2 with chronic aneurysm operated on as emergencies. There were no early deaths in 67 patients operated on electively. Actuarial survival for patients operated for chronic aneurysm was 94.2%, 94.2%, and 94.2% at 1, 5, and 10 years, respectively; that for acute dissection was 72.7%, 63. 6%, and 63.6%; and that for chronic dissection was 100%, 85.7%, and 75.0%. The probability of needing reoperation was 5.7%, 17.3%, and 17.3% at 1, 5, and 10 years. There were no instances of infective endocarditis or thromboembolic complications except in 2 patients operated on early in the series who had cusp extension. At the end of the follow-up, trivial or no aortic regurgitation was demonstrated in 33.3%, mild in 45.6%, moderate in 21.1%, and severe in 0. Valve-sparing operations are feasible in most patients with Marfan syndrome; they are applicable to patients with both dissection and chronic aneurysm. The early and long-term results are encouraging. Results are better in the absence of dissection, and prophylactic operation is warranted in some cases.

We compared results of the Bentall procedure with valve-sparing aortic root replacement (VSRR) for aortic root aneurysm in Marfan syndrome. Marfan syndrome patients who had the Bentall procedure or VSRR at our institution between April 1997 and September 2006 were identified. Follow-up information was obtained from hospital charts and contact with patients or their physicians. Kaplan-Meier survival and propensity score analyses were performed. One hundred forty Marfan syndrome patients had either the Bentall procedure (n = 56) or VSRR (n = 84; 40 remodeling and 44 reimplantation). Bentall patients were older than VSRR patients (38 versus 29 years; p = 0.0001) and had more aortic dissections (16% versus 1%; p = 0.0012); more urgent/emergent surgery (20% versus 2%; p = 0.0008); larger preoperative sinus diameter (5.7 versus 5.1 cm; p = 0.0004); and more preoperative 3+/4+ aortic insufficiency (59% versus 10%; p valve replacement was 90% for VSRR patients. Eight-year survival was 90% for Bentall and 100% for VSRR patients (p = 0.01). Propensity-adjusted regression showed that the Bentall procedure did not predict mortality (p = 1.00) and did not protect from reoperation (odds ratio = 0.28; 95% confidence interval: 0.01 to 4.33; p = 0.36). The Bentall procedure and VSRR have similar operative results in Marfan syndrome. The procedures are distinguished by higher rates of thromboembolism among Bentall patients and higher rates of reoperation among VSRR patients. Lower late survival among Bentall patients probably reflects the preferential use of the Bentall procedure for higher risk patients.

Cardiovascular surgery in the setting of chest wall deformities is a clinical challenge. Pectus excavatum, for example, can cause heart displacement to the left thoracic cavity, following the poor operative field. This report highlights a case in which a successful aortic valve-sparing operation via conventional median sternotomy after correction of the heart displacement due to pectus excavatum using Nuss procedure in Marfan syndrome. This technique can be one surgical option in Marfan syndrome patients with pectus excavatum and thoracic aortic aneurysm under close follow up.

This meta-analysis was performed to analyze the effect of preserving the native aortic valve on short- and long-term prognosis post aortic root reconstruction surgery for patients with Marfan syndrome. Database including Pubmed,Embase, Cochrane library, CNKI, Wanfang,VIP and CBM were searched to collect studies comparing clinical results of valve sparing surgery with composite valve graft surgery for patients with Marfan syndrome. Study quality was assessed by Newcastle-Ottawa Scale and publication bias was assessed by visual inspection of the funnel plot together with Egger test. Clinical outcomes data was extracted from the manuscripts and analyzed with Revman 5.0 supplied by Cochrane collaboration. Seven clinical trials with 690 patients were included. Meta- analysis demonstrated that valve sparing surgery was associated with a lower incidence of re-exploration (RR = 0.51, 95%CI:0.29- 0.90, P 0.05). Valve sparing aortic root reconstruction surgery is a superior procedure to composite valve graft surgery in term of improving the short- and long-term prognosis for patients with Marfan syndrome.

Colobomata are etiologically heterogeneous and may occur as an isolated defect or as a feature of a variety of single-gene disorders, chromosomal syndromes, or malformation syndromes. Although not classically associated with Marfan syndrome, colobomata have been described in several reports of Marfan syndrome, typically involving the lens and rarely involving other ocular structures. While colobomata of the lens have been described in Marfan syndrome, there are very few reports of coloboma involving other ocular structures. We report a newborn boy presenting with coloboma of the iris, lens, retina, and optic disk who was subsequently diagnosed with Marfan syndrome. Marfan syndrome is a disorder of increased TGFβ signaling, and recent work in the mouse model suggests a role for TGFβ signaling in eye development and coloboma formation, suggesting a causal association between Marfan syndrome and coloboma.

The dislocation of the crystalline lens is a common finding in patients with Marfan syndrome (MFS). Scleral intraocular lens (IOL) fixation is an accepted treatment method of this complication. To now, no long-term data on scleral IOL fixation in MFS exist. We present a retrospective study of 27 eyes of 17 MFS patients that underwent scleral lens fixation at our clinic between 1999 and 2012. These patients are compared to an age- and surgeon-matched group of 31 eyes of 27 patients who underwent the same procedure for reasons other than MFS. The median age in the MFS group was 35.4 years versus 35.6 years in the non-MFS group. The median follow-up was 4 years for MFS and 3 years for non-MFS. In the MFS group, significantly more IOL-dislocations occurred than compared to the non-MFS group (30% vs. 6.5%, p = 0.02). Retinal detachment occurred in four MFS-eyes compared to three eyes in the non-MFS group. Biometry prediction error was 1.11 diopters (D) for MFS and 1.33 D for non-MFS (p = 0.11). Median BCVA (best-corrected visual acuity, logMAR) was 0.1 in the MFS group versus 0.3 in non-MFS patients. Scleral lens fixation in MFS patients achieves satisfying visual and refractive outcomes. Our data shows a significantly higher rate of IOL dislocations in patients with MFS. We therefore recommend addressing this complication preoperatively.

Marfan syndrome is an autosomal dominantly inherited connective tissue disorder characterized by defects in the cardiovascular, skeletal and ocular systems. A patient was first examined in 1992 having survived an acute sortic dissection with subsequent composite repair and insertion of a prosthetic aortic valve. Clinical examination revealed arachnodactyly, narrow, high arched palate with dental crowding, an arm span exceeding her height by 10.5 cm, joint laxity and bilateral lens subluxation. Analysis of the family showed affected members in three generations and the fibrillin gene, FBN1, was shown to segregate with the disease when using polymorphic markers including an RsaI polymorphism in the 3{prime}-untranslated region of the gene. Analysis of patient mRNA for this RsaI polymorphism by RT-PCR (reverse transcriptase-PCR) amplification and restriction enzyme digestion of the PCR products showed that the copy of the gene segregating with the disease was not transcribed. No low level expression of this allele was observed despite RT-PCR amplification incorporating radioactively labelled dCTP, thus revealing a null allele phenotype. Western blotting analysis of fibrillin secreted by the patient`s dermal fibroblasts using fibrillin-specific antibodies showed only normal sized fibrillin protein. However, immunohistochemical studies of the patient`s tissue and fibroblasts showed markedly lowered levels in staining of microfibrillar structures compared with age-matched controls. This low level of expression of the protein affected in Marfan syndrome in a patient with such severe clinical manifestations is surprising since current understanding would suggest that this molecular phenotype should lead to a mild clinical disorder.

The study objective was to assess the midterm outcomes and aortic remodeling in patients with Marfan syndrome with complicated acute type B aortic dissection treated with stent-assisted, balloon-induced intimal disruption and relamination. We reviewed all patients treated with stent-assisted, balloon-induced intimal disruption and relamination for a complicated acute type B aortic dissection associated with Marfan syndrome according to the revised Ghent criteria. Between 2015 and November 2017, 7 patients with Marfan syndrome underwent stent-assisted, balloon-induced intimal disruption and relamination for a complicated acute type B aortic dissection. The median age of patients was 47 years (range, 23-70). Four patients had a history of aortic root replacement. Technical success was achieved in 100%. Three patients required an adjunctive procedure for renal artery stenting (n = 2) and iliac artery stenting (n = 1). There was no in-hospital death, 30-day postoperative stroke, spinal cord ischemia, ischemic colitis, or renal failure requiring dialysis. At a median follow-up of 15 months (range, 7-28), 1 patient required aortic arch replacement for aneurysmal degeneration associated with a type Ia endoleak at 2 years, giving a late reintervention rate of 14%. There was no other secondary endoleak. The primary visceral patency rate was 100%. There were no all-cause deaths reported. At last computed tomography scan, all patients had complete aortic remodeling of the treated thoracoabdominal aorta. Distally, at the nonstented infrarenal aortoiliac level, 6 patients had persistent false lumen flow with stable aorto-iliac diameter in 5. One patient had iliac diameter growth (27 mm diameter at last computed tomography scan). Stent-assisted, balloon-induced intimal disruption and relamination of aortic dissection in patients with Marfan syndrome is feasible, safe, and associated with an immediate and midterm persisting thoracoabdominal aortic remodeling.

A prospective, international registry study was initiated to provide contemporary comparative data on short-term clinical outcomes after aortic valve-sparing and aortic valve-replacing root operations in patients with Marfan syndrome. The purpose of this initial report is to describe the study design and to compare early outcomes in the first 151 enrolled patients. We assessed 30-day outcomes in 151 patients who met strict Ghent diagnostic criteria for Marfan syndrome and underwent aortic root replacement with either valve-replacing (n = 46) or valve-sparing techniques (n = 105) at one of 18 participating centers. In the valve replacement group, a mechanical composite valve graft was used in 39 (85%) patients and a bioprosthetic valve in 7 (15%). In the valve-sparing group, David V procedures were performed in 57 (54%) patients, David I in 38 (36%), David IV in 8 (8%), Florida sleeve in 1 (1%), and Yacoub remodeling in 1 (1%). No in-hospital or 30-day deaths occurred. Despite longer crossclamp and cardiopulmonary bypass times in the valve-sparing group, there were no significant between-group differences in postoperative complications. Thirty-day valve-related complications occurred in 2 (4%) patients undergoing valve replacement and in 3 (3%) undergoing valve-sparing procedures (P = .6). The analysis of early outcomes revealed that valve-sparing techniques were the most common approach to root replacement in patients with Marfan syndrome in these centers. The complexity of valve-sparing root replacement did not translate into any demonstrable adverse early outcomes. Subsequent analysis will compare the 3-year durability of these two surgical approaches.

Marfan syndrome (MFS), a relatively common autosomal dominant hereditary disorder of connective tissue with prominent manifestations in the skeletal, ocular, and cardiovascular systems, is caused by mutations in the glycoprotein gene fibrillin-1 (FBN1). Aortic root dilation and mitral valve prolapse are the main presentations among the cardiovascular malformations of MFS. The revised Ghent diagnostics nosology of Marfan syndrome is established in accordance with a combination of major and minor clinical manifestations in various organ systems and the family history. The pathogenesis of Marfan syndrome has not been fully elucidated. However, fibrillin-1 gene mutations are believed to exert a dominant negative effect. The treatment includes prophylactic β-blockers and angiotensin II-receptor blockers in order to slow down the dilation of the ascending aorta and prophylactic aortic surgery. Importantly, β-blocker therapy may reduce TGF-β activation, which has been recognized as a contributory factor in MFS. The identification of a mutation allows for early diagnosis, prognosis, genetic counseling, preventive management of carriers and reassurance for unaffected relatives. The importance of knowing in advance the location of the putative family mutation is highlighted by its straightforward application to prenatal and postnatal screening. The present article aims to provide an overview of this rare hereditary disorder. PMID:25606393

Most patients (75%) with Marfan syndrome present with aortic root dilatation that may require surgical intervention. However, associated cardiovascular disorders are not limited to the aortic root. These patients frequently require consecutive operations on the remaining thoracic aorta or the heart valves. Our intent was to characterize the spectrum of such procedures. Data from all patients with Marfan syndrome undergoing aortic root surgery at our centre between 1988 and 2016 were analysed retrospectively. Overall, 73 patients (26 women) were selected for the study. The median age at 1st operation was 30 years (3-68 years). Indications for aortic root surgery were aneurysm (78%) and dissection (22%). Initially, 33 Bentall procedures and 40 valve-sparing root replacement procedures were performed, with a 97% rate of follow-up completion. The median follow up was 8 years (0-28 years). Survival at 1, 10 and 15 years was 100%, 85% and 82%, respectively. During follow-up monitoring, 48 subsequent procedures were performed in 33 patients (aorta, 23; aortic valve, 11; mitral valve, 7 and combined procedures, 7). The 30-day mortality rate after subsequent procedures was 4.2%. Freedom from subsequent operation and death (combined end-point) after 5, 10 and 15 years was 70%, 53% and 34%, respectively. After the initial surgery, subsequent procedures required in the setting of Marfan syndrome most often involve the remaining native aorta, followed by the aortic and mitral valves. The continued need for additional operative procedures remains high, even decades after the initial surgeries are undertaken. Therefore, long-term patient monitoring at specialized centres is imperative.

We describe concomitant Marfan syndrome and Takayasu's arteritis complicating a pseudoaneurysm of the left ventricular outflow that developed after aortic root reconstruction. A patient was admitted with a high fever four months after initial root reconstruction that included valve sparing (reimplantation) as well as coronary artery reconstruction using a Carrel's button technique. Computed tomography revealed a pseudoaneurysm at the posterior side of the aortic root. We applied a modified Bentall procedure including coronary artery reconstruction using the Piehler technique. Pathological assessment of a specimen of the aorta revealed no central medial necrosis, but significant lymphocytic infiltration and thick fibrous adventitia indicating Takayasu's arteritis. This case was unique in terms of having simultaneous Takayasu's arteritis and cardiovascular manifestations of Marfan syndrome that were surgically treated.

We report an acute aortic dissection type Stanford A extending down to both iliac arteries affecting a 32-year-old woman suspected to have Marfan syndrome during week 37 of pregnancy. In a multidisciplinary approach, and emergency Cesarean section was performed followed by an abdominal hysterectomy and a valve-sparing aortic root replacement using a reimplantation technique. The aorta was replaced up to the hemi arch. Because of the high suspicion of visceral ischemia as confirmed ex juvantibus, an endovascular stent graft was implanted. Molecular testing revealed a frameshift mutation and confirmed the diagnosis of Marfan syndrome. Both the patient and her healthy child underwent an uneventful recovery.

propranolol (N = 32) or no treatment (N = 38) for an average duration of 9.3 years in the control group and 10.7 years in the treatment group. The initial dose of propranolol was 10 mg four times daily and the optimal dose was reached when the heart rate remained below 100 beats per minute during exercise or the systolic time interval increased by 30%. The mean (± standard error (SE)) optimal dose of propranolol was 212 ± 68 mg given in four divided doses daily.Beta-blocker therapy did not reduce the incidence of all-cause mortality (RR 0.24, 95% CI 0.01 to 4.75; participants = 70; low-quality evidence). Mortality attributed to Marfan syndrome was not reported. Non-fatal serious adverse events were also not reported. However, study authors report on pre-defined, non-fatal clinical endpoints, which include aortic dissection, aortic regurgitation, cardiovascular surgery and congestive heart failure. Their analysis showed no difference between the treatment and control groups in these outcomes (RR 0.79, 95% CI 0.37 to 1.69; participants = 70; low-quality evidence).Beta-blocker therapy did not reduce the incidence of aortic dissection (RR 0.59, 95% CI 0.12 to 3.03), aortic regurgitation (RR 1.19, 95% CI 0.18 to 7.96), congestive heart failure (RR 1.19, 95% CI 0.18 to 7.96) or cardiovascular surgery, (RR 0.59, 95% CI 0.12 to 3.03); participants = 70; low-quality evidence.The study reports a reduced rate of aortic dilatation measured by M-mode echocardiography in the treatment group (aortic ratio mean slope: 0.084 (control) vs 0.023 (treatment), P Marfan syndrome, we could draw no definitive conclusions for clinical practice. High-quality, randomised trials are needed to evaluate the long-term efficacy of beta-blocker treatment in people with Marfan syndrome. Future trials should report on all clinically relevant end points and adverse events to evaluate benefit versus harm of therapy.

Marfan syndrome (MFS) is a genetic connective tissue disorder caused by mis folding of the protein fibrillin-1 (coded by the gene FBN1) and alterations in TGFß signalling pathway within the extracellular matrix. Estimates indicate about one in 3,000 to 5,000 individuals have MFS. Patients with MFS have various cardiovascular, skeletal and ocular symptoms: grow to above-average height, dolichostenomelia, arachnodactyly, dolichocephaly and specific facial stigmatisation, abnormal joint flexibility, scoliosis, pectus excavatum/carinatum, limited range of motion in the hips. The most dangerous complication is acute dissection of the ascending aorta, result of a slowly progressive aortic dilatation. Additionally, it may affect the lungs, eyes (lens dislocation) or spinal cord. On the Department of Medical Genetics in Ostrava were between 2002 – 2013 altogether n = 150 individuals examined for possible Marfan syndrome. Complete physical, cardiovascular, ophtamic, orthopaedic examinations and molecular genetic analysis of FBN1, TGFBR1/TGFBR2 were given. N = 51 patients (38 with mutation in FBN1, 75 %) resulted affected by MFS according to the revised Ghent criteria, n = 37 as potential MFS. The diagnosis remains sometimes difficult particularly during childhood, because of the great variability of expression and of the signs evolution with age, but this is a crucial point in order to prevent multiple organ complications. Therapeutic strategies focus on the prevention of aortic dilatation/dissection, currently researches suggest the angiotensin II receptor antagonist Losartan appears to block TGF-beta activity and can slow or halt the formation of aortic aneurysms in MFS.

The diagnosis and surgical treatment of patients with Marfan syndrome remain controversial. It is of utmost importance to identify patients at risk for acute aortic events to establish the correct surgical timing and the appropriate surgical treatment. From May 2008 to December 2012, 500 patients were screened at the Marfan Presidium of the Tor Vergata University Hospital of Rome (Italy). Patients were evaluated by a cardiac surgeon, including echocardiographic, orthopedic, ophthalmologic and dental examinations. All patients received genetic counseling, and genetic sampling was performed if appropriate. The diagnosis of Marfan syndrome was confirmed in 146 patients (29.2%). Fifty-four patients (37%) underwent cardiac surgery on the aortic root, 4 patients had surgery on the mitral valve, 13 patients had combined surgery; 11 cases were emergent surgery for acute aortic dissection. Twenty-eight patients (52%) were operated on at our Division: 13 underwent valve-sparing aortic root replacement (David procedure), 1 underwent Yacoub remodeling procedure and 14 underwent Bentall procedure. Following the establishment of the Marfan Center, the David aortic valve-sparing operation was the most frequently performed procedure compared to the previous period of surgical activity (63 vs 22%, psyndromes. Early surgical treatment is recommended in these patients to achieve optimal results of valve-sparing procedures and life-saving management, especially for patients who live far away from a cardiac surgery center.

Abdominal aortic aneurysms (AAAs) are very rare in Marfan syndrome. We present a case with a young nonsmoking and normotensive male with Marfan syndrome, who developed an infrarenal AAA that presented with rupture to the retroperitoneal cavity causing life-threatening bleeding shock. The patient had acute aortic surgery and survived. Five months before this incident, the patient had uneventful elective aortic root replacement (ad modum David) due to an enlarged aortic root. At that time, his abdominal aorta was assessed with a routine ultrasound scan that showed a normal-sized abdominal aorta. This documents that the aneurysm had evolved very rapidly despite young age and absence of risk factors. Copyright © 2018 Elsevier Inc. All rights reserved.

To review the experience of surgical treatment of aortic root aneurysm of Marfan syndrome. We The clinical data of 84 Marfan syndrome patients, 61 males and 23 females, aged 35 +/- 12 (5 - 62), 41 cases presenting with aortic dissection (Debakey type I in 32 cases and type II in 9), 52 cases with moderate to severe aortic regurgitation, and 9 cases with moderate to severe mitral regurgitation, 43 cases with cardiac function of class I - II, 30 with class III and 11 with class IV according the New York Heart Association (NYHA) standard, who underwent surgical treatment for aortic root aneurysm with a mean diameter of 68 mm +/- 14 mm, were analyzed. Bentall procedure was performed in 68 cases, Wheat procedure in 6, Cabrol procedure in 5, and aortic valve replacement and aortoplasty in 5. Concomitant procedures included mitral value replacement and mitral valvuoplasty in 3 cases respectively. Urgent surgery was conducted in 28 cases, and elective operation in 56 cases. There were 3 in-hospital deaths (3.57%). 76 cases were followed up for a mean duration of 55 +/- 31 months. Three patients underwent reoperation. The cardiac function returned to class I - II except for 2 cases that remained at the class III. Bentall procedure should be the first choice of the surgery for aortic root aneurysm of Marfan syndrome with a low mortality and a good late outcome.

Full Text Available Over the last decades, improvement of medical and surgical therapy has increased life expectancy in Marfan patients. Consequently, the number of such patients requiring secondary interventions on the descending thoracic aorta due to new or residual dissections, and distal aneurysm formation has substantially enlarged. Surgical and endovascular procedures represent two valuable options of treatment, both associated with advantages and drawbacks. The aim of the present manuscript was to review endovascular outcomes in Marfan syndrome and to assess the potential role of Thoracic Endovascular Aortic Repair (TEVAR in this subset of patients.

Marfan syndrome is caused by mutations in the fibrillin-1 gene (FBN1). The most important features affect the cardiovascular system, eyes, and skeleton. The aim of this study was to report the most frequent musculoskeletal alterations observed in 146 patients affected by Marfan syndrome. Fifty-four patients (37%) underwent cardiac surgery and 11 of them received emergent surgery for acute aortic dissection. Ectopia lentis was found in 68 patients (47%) whereas myopia above 3D occurred in 46 patients (32%). Musculoskeletal anomalies were observed in all patients with Marfan syndrome. In 88 patients (60.2%), the associated “wrist and thumb sign” was present; in 58 patients (39.7%), pectus carinatum deformity; in 44 patients (30.1%), pectus excavatum; in 49 patients (33.5%), severe flatfoot; in 31 patients (21.2%), hindfoot deformity; in 54 patients (36.9%), reduced US/LS ratio or increased arm span-height ratio; in 37 patients (25.3%), scoliosis or thoracolumbar kyphosis; in 22 patients (15%), reduced elbow extension (170° or less). Acetabular protrusion was ascertained on radiographs in 27 patients (18.4%). Orthopaedic aspects of the disease are very important for an early diagnosis; however, we have not observed definite correlations between the extent of orthopaedic involvement and aortic complications.

Aortic dilatation and dissection are severe complications during pregnancy that can be fatal to both the mother and the fetus. The risks of these complications are especially high in pregnant patients with Marfan syndrome; however, incidents of descending aortic dissection are very rare. This case report involves a successful Bentall procedure for and recovery from a rare aortic dissection in a pregnant Marfan patient who developed acute type II aortic dissection with severe aortic regurgitation and chronic descending aortic dissection immediately after Cesarean section. Regular follow-up will be needed to monitor the descending aortic dissection.

Data on outcomes after Stanford type A aortic dissection in patients with Marfan syndrome are limited. We investigated the primary surgery and long-term results in patients with Marfan syndrome who suffered aortic dissection. Among 1324 consecutive patients with aortic dissection type A, 74 with Marfan syndrome (58% men; median age, 37 years [first and third quartiles, 29 and 48 years]) underwent surgical repair (85% acute dissections; 68% DeBakey I; 55% composite valved graft, 30% supracoronary ascending replacement, 15% valve-sparing aortic root replacement; 12% total arch replacement; 3% in-hospital mortality) at 2 tertiary centers in the United States and Europe over the past 25 years. The rate of aortic reintervention with resternotomy was 24% (18 of 74) and of descending aorta (thoracic+abdominal) intervention was 30% (22 of 74) at a median follow-up of 8.4 years (first and third quartiles, 2.2 and 12.7 years). Freedom from need for aortic root reoperation in patients who underwent primarily a composite valved graft or valve-sparing aortic root replacement procedure was 95±3%, 88±5%, and 79±5% and in patients who underwent supracoronary ascending replacement was 83±9%, 60±13%, 20±16% at 5, 10, and 20 years. Secondary aortic arch surgery was necessary only in patients with initial hemi-arch replacement. Emergency surgery for type A dissection in patients with Marfan syndrome is associated with low in-hospital mortality. Failure to extend the primary surgery to aortic root or arch repair leads to a highly complex clinical course. Aortic root replacement or repair is highly recommended because supracoronary ascending replacement is associated with a high need (>40%) for root reintervention.

Re-interventions on the thoracic and thoracoabdominal aorta in patients with Marfan syndrome.

Schoenhoff, Florian S; Carrel, Thierry P

2017-11-01

The advent of multi-gene panel genetic testing and the discovery of new syndromic and non-syndromic forms of connective tissue disorders have established thoracic aortic aneurysms as a genetically mediated disease. Surgical results in patients with Marfan syndrome (MFS) provide an important benchmark for this patient population. Prophylactic aortic root surgery prevents acute dissection and has contributed to the improved survival of MFS patients. In the majority of patients, re-interventions are driven by a history of dissection. Patients undergoing elective root repair have a low risk for re-interventions on the root itself. Experienced centers have results after valve-sparing procedures at 10 years comparable with those seen after a modified Bentall procedure. In patients where only the ascending aorta was replaced during the initial surgery, re-intervention rates are high as the root continues to dilate. The fate of the aortic arch in MFS patients presenting with dissection is strongly correlated with the extent of the initial surgery. Not replacing the entire ascending aorta and proximal aortic arch results in a high rate of re-interventions. Nevertheless, the additional burden of replacing the entire aortic arch during emergent proximal repair is not very well defined and makes comparisons with patients undergoing elective arch replacement difficult. Interestingly, replacing the entire aortic arch during initial surgery for acute dissection does not protect from re-interventions on downstream aortic segments. MFS patients suffering from type B dissection have a high risk for re-interventions ultimately leading up to replacement of the entire thoracoabdominal aorta even if the dissection was deemed uncomplicated by conventional criteria. While current guidelines do not recommend the implantation of stent grafts in MFS patients, implantation of a frozen-elephant-trunk to create a stable proximal landing zone for future endovascular or open procedures has

We conducted a randomized, double-blind trial of losartan (100 mg QD) versus atenolol (50 mg QD) for 6 months in adults with Marfan syndrome. Carotid-femoral pulse wave velocity (PWV), central augmentation index (AIx), aortic diameter and left ventricular (LV) function were assessed with arterial tonometry and echocardiography. Thirty-four subjects (18 female; median age 35 years, IQR 27, 45) were randomized. Central systolic and diastolic blood pressure decreased comparably with atenolol and losartan (p = 0.64 and 0.31, respectively); heart rate decreased with atenolol (p = 0.02), but not with losartan. PWV decreased in patients treated with atenolol (-1.15 ± 1.68 m/s; p = 0.01), but not in those treated with losartan (-0.22 ± 0.59 m/s; p = 0.15; between-group difference p = 0.04). In contrast, AIx decreased in the losartan group (-9.6 ± 8.6%; p Marfan syndrome, 6 months of treatment with atenolol improves PWV, whereas losartan reduces the AIx. By improving vascular stiffness via distinct mechanisms of action, there is physiologic value to considering the use of both medications in individuals with Marfan syndrome. © The Author(s) 2015.

Marfan syndrome is an autosomal dominant connective tissue disorder that affects multiple systems, including the skeletal, ligamentous, oculofacial, pulmonary, abdominal, neurological, and cardiovascular systems. Cardiovascular complications, which involve the aorta and aortic valve, contribute most significantly to patient morbidity and mortality. A literature review was conducted on pathophysiology of the disease and recommendations for early diagnosis and treatment. Diagnosis largely relies on clinical features and a thorough history. Echocardiogram is used for monitoring aortic abnormalities and disease progression. Aortic valve-sparing surgery is indicated in any valvular abnormality and in patients with a murmur. Aortic root replacement is indicated prophylactically in women who want to give birth with diameters greater than 40 mm, anyone with a diameter greater than 50 mm, and progressive dilatation of greater than 5 mm per year. Medical management involves antihypertensive therapy. It is imperative for all health care providers to understand the clinical features, progression, and management of Marfan syndrome to appropriately care for their patients. Ensuring regular follow-up and adherence to medical and surgical prophylaxis is essential to patient well-being.

We assessed the outcome in patients with Marfan syndrome operated on exclusively with the aortic valve-sparing reimplantation technique for aortic root aneurysms during more than a decade. Between July 1993 and April 2005, the aortic valve-sparing reimplantation technique (David I) was used in 325 patients. In 59 patients with clinical evidence of Marfan syndrome, procedures were done for aortic root aneurysm (n = 55) or aortic dissection type A (n = 4). Their mean age was 30 +/- 12 years (range, 9 to 62 years), and 37 (63%) were male. Additional procedures were arch replacement in 4 patients, coronary artery bypass grafting in 1, mitral valve surgery in 9, and closure of atrial septal defect in 3. Mean follow-up was 54 +/- 37 months (range, 0 to 139 months). No patient died during the first 30 days postoperatively. Mean bypass time was 163 +/- 34 minutes (range, 99 to 248 minutes), and mean aortic cross clamp time was 126 +/- 28 minutes (range, 78 to 202 minutes). Four patients (6.8%) required rethoracotomy for postoperative bleeding. Five late deaths (8.5%) occurred during follow-up. Reoperation of the reconstructed valve was required in 7 patients. Freedom from reoperation was 88% +/- 5% at 5 years and 80% +/- 9% at 10 years. Mean grade of aortic insufficiency was 1.81 preoperatively compared with 0.20 early postoperatively (p valve should encourage use of this technique in patients with Marfan syndrome.

The objective of this article is to attract the attention of clinical physicians to the rare but extremely relevant clinical pathology of mesenchymal dysplasias (Marfan syndrome, Ehlers-Danlos syndrome, hereditary hemorrhagic telangiectasia) and especially specific characteristics of such diseases during pregnancy. Connective tissue pathology can cover different organs and systems, symptoms of the same disease can vary in different patients thus making diagnostics significantly difficult. Here clinical diagnostic criteria and methods of molecular diagnostics of diseases are described. The pathogenesis of mesenchymal dysplasias is not currently well understood. For the patients with mesenchymal dysplasias pregnancy is fraught with high risk of life-threatening complications. The preferred delivery method for such patients is caesarean section.

We describe concomitant Marfan syndrome and Takayasu’s arteritis complicating a pseudoaneurysm of the left ventricular outflow that developed after aortic root reconstruction. A patient was admitted with a high fever four months after initial root reconstruction that included valve sparing (reimplantation) as well as coronary artery reconstruction using a Carrel’s button technique. Computed tomography revealed a pseudoaneurysm at the posterior side of the aortic root. We applied a modified Bentall procedure including coronary artery reconstruction using the Piehler technique. Pathological assessment of a specimen of the aorta revealed no central medial necrosis, but significant lymphocytic infiltration and thick fibrous adventitia indicating Takayasu’s arteritis. This case was unique in terms of having simultaneous Takayasu’s arteritis and cardiovascular manifestations of Marfan syndrome that were surgically treated. PMID:23555475

Inflammation aggravates disease severity in Marfan syndrome patients.

Full Text Available BACKGROUND: Marfan syndrome (MFS is a pleiotropic genetic disorder with major features in cardiovascular, ocular and skeletal systems, associated with large clinical variability. Numerous studies reveal an involvement of TGF-β signaling. However, the contribution of tissue inflammation is not addressed so far. METHODOLOGY/PRINCIPAL FINDINGS: Here we showed that both TGF-β and inflammation are up-regulated in patients with MFS. We analyzed transcriptome-wide gene expression in 55 MFS patients using Affymetrix Human Exon 1.0 ST Array and levels of TGF-β and various cytokines in their plasma. Within our MFS population, increased plasma levels of TGF-β were found especially in MFS patients with aortic root dilatation (124 pg/ml, when compared to MFS patients with normal aorta (10 pg/ml; p = 8×10(-6, 95% CI: 70-159 pg/ml. Interestingly, our microarray data show that increased expression of inflammatory genes was associated with major clinical features within the MFS patients group; namely severity of the aortic root dilatation (HLA-DRB1 and HLA-DRB5 genes; r = 0.56 for both; False Discovery Rate(FDR = 0%, ocular lens dislocation (RAET1L, CCL19 and HLA-DQB2; Fold Change (FC = 1.8; 1.4; 1.5, FDR = 0% and specific skeletal features (HLA-DRB1, HLA-DRB5, GZMK; FC = 8.8, 7.1, 1.3; FDR = 0%. Patients with progressive aortic disease had higher levels of Macrophage Colony Stimulating Factor (M-CSF in blood. When comparing MFS aortic root vessel wall with non-MFS aortic root, increased numbers of CD4+ T-cells were found in the media (p = 0.02 and increased number of CD8+ T-cells (p = 0.003 in the adventitia of the MFS patients. CONCLUSION/SIGNIFICANCE: In conclusion, our results imply a modifying role of inflammation in MFS. Inflammation might be a novel therapeutic target in these patients.

In patients with Marfan syndrome (MFS), valve reimplantation has been proposed as superior to root remodeling. In the present study, both forms of valve-preserving root repair were applied and mid-term results analyzed in MFS patients compared to a propensity score-matched cohort. Among 604 patients who underwent valve-preserving aortic root surgery between 1995 and 2011 at the authors' institution, 33 MFS patients (16 males, 17 females; mean age 31 +/- 12 years) underwent either remodeling (n=21) or reimplantation (n=12). All patients were followed up echocardiographically, and the outcome with regard to late aortic valve regurgitation (AR) grade EII and reoperation on the aortic valve was compared between MFS patients and the matched cohort (n=33). Baseline characteristics and operative data were similar between the groups. Actuarial freedom from AR > or = II at seven years was 86 +/- 8% in MFS patients and 90 +/- 10% in matched non-MFS patients (p = 0.94). Actuarial freedom from reoperation at seven years was 90 +/- 7% in MFS patients and 100% in non-MFS patients (p = 0.79). In Cox's proportional hazard's model, no independent risk factor, including MFS, was found for recurrent AR or reoperation. Within the MFS patients, remodeling and reimplantation provided an almost identical freedom from late AR > or = II and reoperation up to five years postoperatively (p = 0.55 and 0.99, respectively). The stability of valve-preserving aortic root repair was comparable between patients with or without MFS. Both forms of valve-preserving root repair can provide similar mid-term results for MFS patients, primarily according to their root geometry. However, additional long-term follow up data based on a larger number of patients are required to confirm the evidence obtained to date.

Full Text Available Cardiovascular comorbidities to the Marfan syndrome may induce hemodynamic instability especially in the parturients during labor or delivery. For anesthesiologists, it is challenging to maintain hemodynamic stability during Cesarean section in those patients with Marfan syndrome. Remifentanil is an ultra-short-acting opioid with rapid onset and offset of action which provides cardiovascular stability during surgery. Together with remifentanil, the use of a laryngeal mask airway can reduce the risk of hypertensive response followed by tracheal intubation. We describe the successful administration of remifentanil and application of laryngeal mask airway for emergent Cesarean section performed under general anesthesia in a patient with Marfan syndrome complicated by ascending aortic aneurysm and heart failure. The use of remifentanil (loading dose of 1 μg/kg for 1 min, 2 min before induction; thereafter continuous infusion dose of 0.1 μg/kg/min was useful to maintain hemodynamic stability of the parturient throughout the surgery without neonatal respiratory depression.

This study aims to investigate how fatigue affects adults with verified Marfan syndrome (MFS) in their daily lives, by examining fatigue levels and prevalence of severe fatigue compared to the general Norwegian population and individuals with other comparable chronic conditions. We investigated associations between socio-demographic characteristics, Marfan-related health problems, pain and fatigue. A cross-sectional study was conducted, using a postal questionnaire including the Fatigue Severity Scale (FSS) and questions on socio-demographic characteristics, Marfan-related health problems and pain. One hundred seventeen persons with MFS were invited to participate, 73 answered (62%). Participants reported significantly higher FSS scores and prevalence of severe fatigue compared to the general Norwegian population and patients with rheumatoid arthritis (RA), but lower than for other chronic conditions. Participants with chronic pain reported higher fatigue scores than those without chronic pain. Participants on disability benefits reported higher fatigue scores than participants who were working or enrolled in higher education. Marfan-related health problems like aortic dissection and use of blood pressure medication were not significantly associated with fatigue. In multivariable regression analyses chronic pain and employment status were significantly associated with fatigue. The final multivariable model explained 24% of the variance in fatigue scores. Our results show that fatigue is common in MFS patients and that it interferes with their daily lives. Chronic pain and employment status show significant associations to fatigue. This implies that fatigue is important to address when meeting MFS patients in clinical practice. There is need for more research on fatigue in Marfan syndrome. © 2014 Wiley Periodicals, Inc.

Fibrillin mutations in the Marfan syndrome

Energy Technology Data Exchange (ETDEWEB)

Price, C.E.; Wang, M.; Wang, J.; Godfrey, M. [Univ. of Nebraska Medical Center, Omaha, NE (United States)

1994-09-01

The Marfan syndrome (MFS) is an autosomal dominant heritable disorder of connective tissue manifested by variable and pleiotropic defect in the skeletal, ocular, and cardiovascular systems. We have recently begun to use intron-specific primers that have become available through the International Marfan Syndrome Consortium to screen for fibrillin mutations in MFS patients. Using the genomic PCR-based approach in addition to RT-PCR methodologies, we have identified several novel mutations. A single base insertion was identified in all affected individuals of one family. The insertion of an {open_quote}A{close_quote} at position 1891 in exon 15 causes a premature stop codon and thus a truncated polypeptide. The truncated protein of 617 amino acids has an expected molecular weight of 63 kD. Metabolic labeling and immunoprecipitation studies are in progress. A C{r_arrow}T transition at position 1634 in exon 12 causing a 5th position Cys to Phe substitution in an EGF-like motif was observed in another MFS patient. Finally, we have identified a G{r_arrow}A transition at the +1 position of the donor splice site that causes the deletion of fibrillin exon 32 in a patient with the neonatal form of MFS. Exon 32 is a precursor EGF-like calcium binding motif that is located in a single stretch of 12 similar domains. We had previously identified the skipping of this exon due to an A{r_arrow}T transversion at the -2 position of the consensus acceptor splice site in another patient with neonatal MFS. The reason that the skipping of exon 32 causes a neonatal lethal MFS phenotype is presently unclear. These studies will help elucidate the role of diverse regions of fibrillin.

Marfan syndrome (MFS) is a disorder of autosomal dominant inheritance, in which aortic root dilation is the main cause of morbidity and mortality. Fibrillin-1 (FBN-1) gene mutations are found in more than 90% of MFS cases. The aim of our study was to summarise variants in FBN-1 and establish the genotype-phenotype correlation, with particular interest in the onset of aortic events, in a broad population of patients with an initial clinical suspicion of MFS. This single centre prospective cohort study included all patients presenting variants in the FBN-1 gene who visited a Hereditary Aortopathy clinic between September 2010 and October 2016. The study included 90 patients with FBN-1 variants corresponding to 58 non-interrelated families. Of the 57 FBN-1 variants found, 25 (43.9%) had previously been described, 23 of which had been identified as associated with MFS, while the the remainder are described for the first time. For 84 patients (93.3%), it was possible to give a definite diagnosis of Marfan syndrome in accordance with Ghent criteria. 44 of them had missense mutations, 6 of whom had suffered an aortic event (with either prophylactic surgery for aneurysm or dissection), whereas 20 of the 35 patients with truncating mutations had suffered an event (13.6% vs. 57.1%, p importance not only in the diagnosis, but also in risk stratification and clinical management of patients with suspected MFS.

Dilation of the ascending aorta and aortic dissections are often seen in Marfan syndrome; however, true aneurysms of the subclavian and axillary arteries rarely seem to develop in patients who have this disease. We present the case of a 58-year-old man with Marfan syndrome who had undergone a Bentall procedure and thoracoabdominal aortic repair for an aortic dissection and who later developed multiple aneurysmal dilations of his right subclavian and axillary arteries. The aneurysms were succe...

The authors retrospectively analyzed early and late results of surgical treatment for 79 Marfan patients with aneurysms and dissection of the proximal aorta. From September 1979 to February 1996, 79 patients with Marfan syndrome underwent aortic root replacement using composite grafts (n=68, Bentall-technique 63, button-technique 5), and ascending aortic replacement with a valve-sparing procedure (n=11). There were 12 patients (15.2%) who simultaneously received partial or total arch replacement. 55 patients (69.6%) were male, and 24 female (30.4%). The average age was 33.8 years. Forty-one patient (51.9%) had non-dissecting aneurysms while the remaining 38 patients suffered from either acute (24.0%) or chronic aortic dissection (24.0%). The aortic valve was involved in 97.5% of all cases. The total early mortality (valve-sparing operation and in those with chronic aortic dissection. The follow-up rate was 98.7%. During a mean follow-up of 68+/-25 months 10 patients (13.3%) died and cardiac complications were a common cause of the late deaths. There was no late mortality in the valve-sparing operations during a mean follow-up period of 8+/-6 months, however, 1 required valve replacement. 19 (25.3%) of the 75 patients surviving late have undergone 25 secondary operations on the cardiovascular system. Reoperations at aortic sites distant from the original were much more frequent after primary repair for acute and chronic dissection when compared to non-dissecting aneurysms (pMarfan-patients with non-dissecting and dissecting aneurysms of the aortic root. Our early experience in 11 patients with valve-sparing procedures indicated that this,variant may be the better choice in selected patients.

An Overlap Syndrome of Pigment Dispersion and Pigmentary Glaucoma accompanied by Marfan Syndrome: Case Report with Literature Review.

'Overlap syndrome' describes the situation in which two or more 'independent' conditions are present, either one of which could cause a particular finding. This current presentation reports a case with bilateral pigment dispersion syndrome (PDS), advanced pigmentary glaucoma (PG), and the Marfan syndrome, with bilateral subluxation of the lenses, and large short-term and long-term fluctuations of intraocular pressure. It is interesting to consider whether the associated advanced glaucomatous nerve damage could be a manifestation of just the PDS, just the Marfan syndrome, or rather a combination of these two overlapping independent conditions.

To evaluate the mid-term outcomes, and the aortic remodeling in Marfan syndrome (MFS) patients with type B dissection that were treated with endovascular repair. MFS is a relative contraindication to thoracic endovascular aortic repair (TEVAR). Mid-term aortic outcomes data in MFS after TEVAR are limited, and the occurrence of late events remains unclear. Of 89 patients that underwent TEVAR between September 2002 and February 2011, 10 patients with mid-term follow-up fulfilled the Ghent criteria for MFS and complicated type B dissection. High risk for open surgery was documented in 90%. The mean age was 35.1 ± 9.4 years and all patients presented with acute aortic syndrome complicating a chronic type B dissection (DeBakey type IIIb). Five patients underwent a Bentall surgical procedure previous to endovascular repair, and in four patients initial TEVAR was followed by surgery of the ascending aorta. Treatment was limited to endovascular repair in only one patient. In-hospital mortality was 10%. At a mean follow-up of 59.6 ± 38.9 months, the cumulated mortality was of 20% and late mortality 11.1%. The rate of secondary endoleak was 44.4%, and late reintervention of 33.3%. Survival freedom from cardiovascular death at 8 years was 80.0%, and positive remodeling was documented in 37.5% of patients. Our results suggest that TEVAR is feasible, safe, and associated with a high reintervention rate and reduced rate of positive aortic remodeling in patients with Marfan syndrome. Survival at 8 years was comparable to contemporary series of open repair. Copyright © 2013 Wiley Periodicals, Inc.

The aim was to investigate birth characteristics, obstetric and neonatal outcomes of the first childbirth in women with Marfan syndrome by use of Swedish national registers since pregnancy-related outcomes in women with Marfan syndrome have only been sparsely investigated. In this national population-based cohort study and matched case-control study of Swedish women born 1973-1993, women with Marfan syndrome (n=273) were compared to women without the condition (n=1 017 265). The study population was followed until 2013. A total of 364 553 mother-firstborn-offspring pairs were analyzed. Sixty-one women with Marfan syndrome became mothers. Women with Marfan syndrome were also compared to 543 healthy controls. Women with Marfan syndrome were more often born preterm (pMarfan syndrome had no increased risk of giving birth by cesarean section (p=0.079). No increased neonatal risks in their children were found. Women with Marfan syndrome were less likely to give birth than those without (pMarfan syndrome were more likely to be born preterm, SGA and by cesarean section. These increased risks of preterm birth and SGA babies were not found in connection with their own first childbirth. Pregnancies with known fetal Marfan syndrome have to be carefully monitored. The results are important for obstetricians giving preconception counseling and treating women with Marfan syndrome. Further studies are needed to evaluate risks during pregnancy and long-term effects of pregnancy on the cardiovascular status of women with Marfan syndrome. Copyright © 2017 Elsevier B.V.

The objective of this study was to compare the results of aortic valve-sparing reimplantation and aortic root replacement with mechanical valve conduits in patients with Marfan syndrome undergoing operation for aortic root aneurysms. Patients and methods Between March 1979 and April 2002, 119 patients with clinical evidence of Marfan syndrome underwent composite graft replacement with mechanical valve conduits (n = 74) or aortic valve-sparing reimplantation according to David (n = 45). The underlying causes were aortic dissection type A (43 patients) and aneurysms (76 patients). Patients undergoing aortic valve reimplantation were younger compared with patients undergoing composite grafting (28 vs 35 years, P =.002) and had longer intraoperative aortic crossclamp times (125 vs 78 minutes, P valve reimplantation (P =.15). Mean follow-up was 30 months for patients undergoing aortic valve reimplantation and 114 months for patients undergoing composite grafting. Freedom from reoperation and death after 5 years postoperatively was 92% and 89% in patients undergoing composite grafting and 84% and 96% in patients undergoing aortic valve reimplantation (P =.31; P =.54), respectively. Thromboembolic complications or late postoperative bleeding occurred in 17 patients undergoing composite grafting, and an early postoperative event occurred in 1 patient undergoing aortic valve reimplantation. The results of aortic valve reimplantation and composite grafting of the aortic valve and ascending aorta with mechanical valve conduits are similar with regard to early and mid-term postoperative mortality and to the incidence of late reoperations in patients with Marfan syndrome. The low risk of thromboembolic or bleeding complications favors aortic valve reimplantation in these patients.

Full Text Available BACKGROUND: Although periodontitis is a risk factor for cardiovascular disease (CVD, the influence of periodontitis on Marfan syndrome (MFS with CVD is unclear. The aim of this study was to assess the relationship between periodontal bacterial burden and MSF with CVD. METHODS AND RESULTS: The subjects were patients with MFS with CVD (n = 47; age and gender matched non-MFS CVD patients (n = 48 were employed as controls. Full-mouth clinical measurements, including number of teeth, probing of pocket depth (PD, bleeding on probing (BOP and community periodontal index (CPI were recorded. We also evaluated the existence of three periodontal pathogens, Porphyromonas gingivalis, Aggregatibacter actinomycetemcomitans, and Prevotella intermedia using polymerase chain reaction assays. Serum antibody titers against the pathogens were also measured. We revealed that MFS with CVD patients had periodontitis more frequently than the age and gender matched non-MFS CVD control subjects. MFS with CVD patients had significantly severer periodontitis, fewer remaining teeth and deeper PD compared to the non-MFS CVD controls. Furthermore, the serum antibody titer level against Prevotella intermedia was significantly lower in MFS plus CVD patients compared to the non-MFS CVD patients. CONCLUSION: Periodontitis may influence the pathophysiology of cardiovascular complications in MFS patients. A specific periodontal pathogen might be a crucial therapeutic target to prevent CVD development.

Cardiovascular complications in Marfan syndrome (MFS) make all its seriousness. Taking as a basis the Ghent criteria, we conducted a family screening from an index case. The objective was to describe the clinical characteristics of MFS anomalies and to detect cardiovascular complications in our patients. Six subjects were evaluated. Patients had to be in the same uterine siblings of the index case or be a descendant. The objective was to search for MFS based on the diagnostic criteria of Ghent and, subsequently, detecting cardiovascular damage. The average age was 24 years. The examination revealed three cases of sudden death in a context of chest pain. Five subjects had systemic involvement with a score ≥ 7 that allowed to the diagnosis of MFS. Two patients had simultaneously ectopia lentis and myopia. In terms of cardiovascular damage, there were three cases of dilatation of the aortic root, two cases of aortic dissection of Stanford's type A with severe aortic regurgitation in one case and moderate in the other. There were three patients with moderate mitral regurgitation with a case by valve prolapse. The family screening is crucial in Marfan syndrome. It revealed serious cardiovascular complications including sudden death and aortic dissection.

Purpose: To compare the aortic compliance of the normal-sized aorta of adolescents with Marfan syndrome and healthy controls using MR measurements of the aortic distensibility and pulse wave velocity. Materials and Methods: Fourteen patients (median age: 15 [9-21] years) and 11 healthy subjects (23 [12-32] years) were examined at 1.5 T. The MR protocol included 2D steady-state free precession (SSFP)-CINE MRI of the aortic distensibility and PC-MRI of the pulse wave velocity. All measurements were positioned perpendicular to the descending aorta at the level of the diaphragm for assessing the changes in the aortic cross-sectional areas and additionally above and below this plane for assessing the pulse wave velocity. In addition contrast-enhanced 3D-MR angiography was performed in adolescents with Marfan syndrome to exclude morphologic changes and to prove normal-sized aorta. Results: Compared with control subjects, adolescents with Marfan syndrome had significantly decreased distensibility and significantly increased pulse wave velocity ({chi}{sup 2}-test, p = 0.0002) using an age-related non-linear regression analysis. The related aortic compliance was significantly decreased ({chi}{sup 2}-test, p = 0.0002). There was a good correlation between the two methods (r = 0.86). A low intraobserver variability was found for both methods ({<=} 2 %). (orig.)

Full Text Available Disorders of lipid metabolism can cause variable clinical presentations, often involving skeletal muscle, alone or together with other tissues. A 19-year-old boy presented with a 2-year history of muscle pain, cramps, exercise intolerance and progressive weakness of proximal lower limbs. Examination revealed skeletal markers of Marfan syndrome in the form of increased arm span compared with height, Kyphoscoliois, moderate pectus excavatum, high arched palate and wrist sign. He also had mild neck flexor weakness and proximal lower limb weakness with areflexia. Pathologic findings revealed lipid-laden fine vacuoles in the muscle fibers. Possibility of carnitine deficiency myopathy was considered and the patient was started on carnitine and Co Q. The patient made remarkable clinical improvement over the next 2 months. This case is reported for rarity of the association of clinical markers of Marfan syndrome and lipid storage myopathy and sparse literature on lipid storage myopathy in the Indian context.

Neonatal Marfan syndrome caused by an exon 25 mutation of the Fibrillin-1 gene: We describe a male infant with severe arachnodactyly, hypermobility of the fingers, flexion contractures of elbows, wrists, hips, and knees, microretrognathia, crumpled ears, rockerbottom feet, loose redundant skin, and lens dislocations. Cardiac valve insufficiency and aortic dilatation resulted in cardiac failure, decompensated with digitalisation and death occurred at the age of 4 months. This case represents the severe end of the clinical spectrum of Marfan syndrome, namely neonatal Marfan syndrome. Molecular diagnostic analyses confirmed a de novo exon 25 mutation in the FBN1 gene.

Objective. To determine how well conventional radiographic findings can predict the presence of dural ectasia in Marfan patients.Design and patients. Twelve Marfan patients without dural ectasia and 21 Marfan patients with dural ectasia were included in the study. Five radiographic measurements were made of the lumbosacral spine: interpediculate distance, scalloping value, sagittal canal diameter, vertebral body width, and transverse process width.Results. The following measurements were significantly larger in patients with dural ectasia: interpediculate distances at L3-L4 levels (P 38.0 mm, sagittal diameter at S1 >18.0 mm, or scalloping value at L5 >5.5 mm.Conclusion. Dural ectasia in Marfan syndrome is commonly associated with several osseous changes that are observable on conventional radiographs of the lumbosacral spine. Conventional radiography can detect dural ectasia in patients with Marfan syndrome with a very high specificity (91.7%) but a low sensitivity (57.1%). (orig.)

Marfan's syndrome is a hereditary connective tissue disease, in which cardiovascular abnormalities (especially aortic root dilatation) are the most important cause of morbidity and mortality. In this report, we describe two 24-year-old twins, with a history of surgery for lens subluxation and severe cardiovascular manifestations secondary to Marfan's syndrome. One of the twins suffered a type A aortic dissection, which required replacement of the ascending aorta, and the other twin had an aneurysmal dilatation of the ascending aorta (46mm) and was prescribed medical treatment with atenolol and periodic controls to detect the presence of a critical diameter (50mm) that would indicate the need for prophylactic surgery.

In Marfan syndrome, the most common cardiovascular abnormalities are dilatation of the aorta and aortic valve regurgitation in adult patients. Mitral valve dysfunction is the most common cause of morbidity and mortality in infants and children with Marfan syndrome, and is not frequently operated on in adult Marfan patients who undergo surgery for diseases of the aortic root and total aorta. This report describes a successfully three-staged operation for a 24 year-old man with Marfan syndrome who underwent an emergent Bentall operation and aortic arch replacement, total aortic replacement and mitral valve replacement over 2 years. Mitral valve regurgitation was mild but increased after the second operation. The graft was tightly adhesive and invasive to the sternum. Endoscopic view was helpful to avoid graft damage at resternotomy. The postoperative course was uneventful in each operation. Microscopic examination of the mitral valve leaflets showed abnormal increase of mucopolysaccharides, and disruption and fragmentation of elastic fibers.

To evaluate the clinical characteristics of aortic dissection in pregnant patients with Marfan syndrome and the maternal and fetal outcomes in cardiovascular surgery. Seven pregnant women with Marfan syndrome with aortic dissection were identified, who were treated in Beijing Anzhen Hospital Affiliated to Capital Medical University between January 2012 and September 2014. Patient charts were reviewed for cardiovascular surgery, occurrence of complications, clinical features and the maternal and fetal outcomes. (1) Among 7 patients, 4 cases were diagnosed as type A aortic dissection and 3 were cases diagnosed as type B aortic dissection. The diagnosis mainly depends on CT angiography. New York Heart Association (NYHA) classify into 5 of level II, 1 of level III, 1 of leveI IV. Except for 1 patient with cardiac tamponade lead to heart failure, the remaining 6 cases had no complications. (2) Three patients underwent heart surgery with cardiopulmonary bypass in second trimester and two patients underwent heart surgery in third trimester. Two patients terminated pregnancy before heart surgery (one of whom underwent artificial abortion, one of whom underwent cesarean section in second trimester). (3) The methods of cardiovascular surgeries were as follow: 3 of Bentall+Sun', 1 of Bentall+Sun'+ right coronary artery bypass grafting, 1 of Bentall, 1 of the whole chest aorta replacement surgery, and 1 of femoral artery catheter chest aorta with membrane mesh stent implantation. The diameter of aortic roots measured during operation were 5 cm in 2 cases, 7 cm in 2 cases and 10 cm in 2 cases respectively. Among the 7 cases, 3 were conducted cesarean sections during cardiovascular surgery, 1 was terminated pregnancy due to intrauterine fetal death after cardiovascular surgery, and 1 was conducted cesarean section due to severe early-onset preeclampsia at 30 weeks of pregnancy after cardiovascular surgery. (4) Among the 7 cases, 3 were conducted cesarean sections during

Marfan syndrome (MFS) is a connective tissue disorder that is often associated with the fibrillin-1 (Fbn1) gene mutation and characterized by cardiovascular alterations, predominantly ascending aortic aneurysms. Although neurovascular complications are uncommon in MFS, the improvement in Marfan patients' life expectancy is revealing other secondary alterations, potentially including neurovascular disorders. However, little is known about small-vessel pathophysiology in MFS. MFS is associated with hyperactivated transforming growth factor (TGF)-β signaling, which among numerous other downstream effectors, induces the NADPH oxidase 4 (Nox4) isoform of NADPH oxidase, a strong enzymatic source of H2O2 We hypothesized that MFS induces middle cerebral artery (MCA) alterations and that Nox4 contributes to them. MCA properties from 3-, 6-, or 9-mo-old Marfan (Fbn1(C1039G/+)) mice were compared with those from age/sex-matched wild-type littermates. At 6 mo, Marfan compared with wild-type mice developed higher MCA wall/lumen (wild-type: 0.081 ± 0.004; Marfan: 0.093 ± 0.002; 60 mmHg; P Marfan mice with Nox4 deficiency (Nox4(-/-)). Strikingly, Nox4 deletion in Marfan mice aggravated MCA wall thickening (cross-sectional area; Marfan: 6,660 ± 363 μm(2); Marfan Nox4(-/-): 8,795 ± 824 μm(2); 60 mmHg; P < 0.05), accompanied by decreased TGF-β expression and increased collagen deposition and Nox1 expression. These findings provide the first evidence that Nox4 mitigates cerebral artery structural changes in a murine model of MFS. Copyright © 2016 the American Physiological Society.

Severe neonatal Marfan syndrome has features of the Marfan syndrome and congenital contractural arachnodactyly present at birth, along with unique features such as loose, redundant skin and pulmonary emphysema. Since the Marfan syndrome and congenital contractural arachnodactyly are due to mutations in different genes, it has been uncertain whether neonatal Marfan syndrome is due to mutations in the fibrillin gene on chromosome 15 or in another gene. The authors studied an infant with severe neonatal Marfan syndrome. Dermal fibroblasts were metabolically labeled and found to secrete fibrillin inefficiently when compared with control cells. Reverse transcription and amplification of the proband's fibroblast RNA was used to identify a 3-bp insertion between nucleotides 480-481 or 481-482 of the fibrillin cDNA. The insertion maintains the reading frame of the protein and inserts a cysteine between amino acids 160 and 161 in an epidermal growth-factor-like motif of fibrillin. This 3-bp insertion was not found in the fibrillin gene in 70 unrelated, unaffected individuals and 11 unrelated individuals with the Maran syndrome. The authors conclude that neonatal Marfan syndrome is the result of mutations in the fibrillin gene on chromosome 15 and is part of the Marfan syndrome spectrum. 32 refs., 3 figs.

Pregnancy in patients with Marfan's syndrome (MFS) carries an increased risk of cardiovascular complications, resulting in increased maternal and fetal mortality and morbidity. Literature on MFS pregnant patients is relatively sparse, and there has yet to be a concrete consensus on the management of this unique patient population. The purpose of our paper is to provide a literature review of case reports and studies on MFS during pregnancy (published between 2005 and 2015) and to explore cardiovascular outcomes of patients with MFS. Of the 852 women in our review, there were 1112 pregnancies, with an aortic dissection rate of 7.9% and mortality of 1.2%. Data demonstrated a trend that patients whose aortic diameter ≥40 mm had a greater rate of dissection than MFS patients whose aortic diameter pregnancy or currently pregnant should be carefully counseled about the maternal and fetal risks throughout pregnancy. MFS patients whose aortic diameters ≥40 mm should be advised to ideally await pregnancy until prophylactic aortic surgery. As MFS varies in its phenotypic expression, each patient's risk of adverse cardiac events should be assessed individually through a joint Maternal Fetal Medicine and Cardiology Center. © 2017 Wiley Periodicals, Inc.

We reviewed the evolution of practice and late results of aortic root replacement (ARR) in Marfan syndrome patients at our institution. A retrospective clinical review of Marfan patients undergoing ARR at our institution was performed. Follow-up data were obtained from hospital and office records and from telephone contact with patients or their physicians. Between September 1976 and September 2006, 372 Marfan syndrome patients underwent ARR: 269 had a Bentall composite graft, 85 had valve-sparing ARR, 16 had ARR with homografts, and 2 had ARR with porcine xenografts. In the first 24 years of the study, 85% received a Bentall graft; during the last 8 years, 61% had a valve-sparing procedure. There was no operative or hospital mortality among the 327 patients who underwent elective repair; there were 2 deaths among the 45 patients (4.4%) who underwent emergent or urgent operative repair. There were 74 late deaths (70 Bentalls, 2 homograft, and 2 valve-sparing ARRs). The most frequent causes of late death were dissection or rupture of the residual aorta (10 of 74) and arrhythmia (9 of 74). Of the 85 patients who had a valve-sparing procedure, 40 had a David II remodeling operation; there was 1 late death in this group, and 5 patients required late aortic valve replacement for aortic insufficiency. A David I reimplantation procedure using the De Paulis Valsalva graft has been used exclusively since May 2002. All 44 patients in this last group have 0 to 1+ aortic insufficiency. Prophylactic surgical replacement of the ascending aorta in patients with Marfan syndrome has low operative risk and can prevent aortic catastrophe in most patients. Valve-sparing procedures, particularly using the reimplantation technique with the Valsalva graft, show promise but have not yet proven as durable as the Bentall.

Previous studies demonstrated that patients with different FBN1 mutations often present more considerable phenotypic variation compared to different members of the related family carrying a same mutation. The purpose of our study was to identify pathogenic mutation and provide more information about genotype-phenotypic correlations in a large Chinese family with Marfan syndrome. 15 related family members from a Chinese 4-generation pedigree with Marfan syndrome underwent physical, ophthalmologic, radiological and cardiovascular examinations. The propositus has De Bakey III aortic dissection and didn't fulfill the revised Ghent criteria for Marfan syndrome. Nine family members have ectopia lentis and their echocardiogram was normal. Five other family members have no evidence of Marfan syndrome. Genomic DNA was isolated from blood leukocytes. The exome sequencing was employed on the propositus, then the Sanger sequencing was conducted for mutation verification in other 14 participants of this family. The causative mutation in FBN1 discovered in the propositus was a known heterozygous missense mutation, c.1633T>G (p.R545C), in exon 14 (NM 000138). This same mutation was also identified in all 9 ectopia lentis patients and one unaffected 8-year-old girl. However, the same mutation was not discovered in other 4 unaffected family members. Our data enhance the information of genotype-phenotype correlation owing to FBN1 mutations. To our current knowledge, we firstly reported that the same FBN1 mutation, c. 1633C>T (Arg545Cys), was detected simultaneously in three different cardinal phenotypes (ectopia lentis, aortic dissection and unaffected) within one family. The unaffected girl with FBN1 mutation may presumably represent a rare case of nonpenetrance. Copyright © 2016 Elsevier B.V. All rights reserved.

Dilation of the ascending aorta and aortic dissections are often seen in Marfan syndrome; however, true aneurysms of the subclavian and axillary arteries rarely seem to develop in patients who have this disease. We present the case of a 58-year-old man with Marfan syndrome who had undergone a Bentall procedure and thoracoabdominal aortic repair for an aortic dissection and who later developed multiple aneurysmal dilations of his right subclavian and axillary arteries. The aneurysms were successfully repaired by means of a surgical bypass technique in which a Dacron graft was placed between the carotid and brachial arteries. We also discuss our strategy for determining the optimal surgical approach in these patients.

Marfan syndrome (MFS) is a rare, severe, chronic, life-threatening disease with multiorgan involvement that requires optimal multidisciplinary care to normalize both prognosis and quality of life. In this article, each key team member of all the medical disciplines of a multidisciplinary health care team at the Hamburg Marfan center gives a personal account of his or her contribution in the management of patients with MFS. The authors show how, with the support of health care managers, key team members organize themselves in an organizational structure to create a common meaning, to maximize therapeutic success for patients with MFS. First, we show how the initiative and collaboration of patient representatives, scientists, and physicians resulted in the foundation of Marfan centers, initially in the US and later in Germany, and how and why such centers evolved over time. Then, we elucidate the three main structural elements; a team of coordinators, core disciplines, and auxiliary disciplines of health care. Moreover, we explain how a multidisciplinary health care team integrates into many other health care structures of a university medical center, including external quality assurance; quality management system; clinical risk management; center for rare diseases; aorta center; health care teams for pregnancy, for neonates, and for rehabilitation; and in structures for patient centeredness. We provide accounts of medical goals and standards for each core discipline, including pediatricians, pediatric cardiologists, cardiologists, human geneticists, heart surgeons, vascular surgeons, vascular interventionists, orthopedic surgeons, ophthalmologists, and nurses; and of auxiliary disciplines including forensic pathologists, radiologists, rhythmologists, pulmonologists, sleep specialists, orthodontists, dentists, neurologists, obstetric surgeons, psychiatrist/psychologist, and rehabilitation specialists. We conclude that a multidisciplinary health care team is a means

A patient with Marfan syndrome with previous Bentall operation for mitral and tricuspid valve repair, required orthotopic cardiac transplantation for end stage cardiomyopathy. Postoperatively he suffered type-B aortic dissection, despite normal aortic diameters. Following sudden increase of aortic diameters, two years later, he underwent successful stent graft implantation. In patients with Marfan syndrome, post transplantation morbidity is high, with a 40% incidence of thoracic aortic dissection. This case highlights the potential of endovascular approach for treating post-transplantation aortic dissection.

Marfan syndrome is a systemic disorder of the connective tissue inherited as an autosomal dominant trait. The disorder imparts significant morbidity and martality. The etiology of the disorder remains elusive. A recent study localized the gene for Marfan syndrome on chromosome 15. The authors present data showing that marker D15S48 is genetically linked to Marfan syndrome. Pairwise linkage analysis gave a maximum lod (logarithm of odds) score of Z = 11.78 at {theta} = 0.02. Furthermore our data suggest that the Marfan syndrome locus is possibly flanked on either side by D15S48 and D15S49.

Marfan syndrome (MFS) is a disorder of the connective tissues. Alterations of the elastic fibers may manifest in different tissues especially in the skeletal, cardiovascular and ocular system. Oral manifestations like orthodontic or skeletal anomalies and fragility of the temporomandibular joint have been well described by various authors. However, no data are available regarding a possible periodontal involvement of MFS. Hence, the aim of the present study was to investigate for the first time if MFS may increase the susceptibility to periodontitis. A comprehensive periodontal examination including documentation of probing pocket depth, gingival recession, clinical attachment level, and bleeding on probing was conducted in all patients. In addition, dental conditions were assessed by determining the Index for Decayed, Missing and Filled Teeth (DMFT) and a self-administered questionnaire was filled out by patients. For statistical analysis, the unpaired t-Test was applied (level of significance: p endocarditis.

Marfan syndrome gene search intensifies following identification of basic defect

Somewhere, quite possible along chromosomes 8 and/or 15, the gene(s) for Marfan syndrome will be found. The search is intensifying following a report that faulty scaffolding in the body's connective tissue appears to be the long sought after defect behind the syndrome, and inherited disorder that has caused the premature death of young, healthy-looking individuals. Finding that something in the living masonry of the human body has proven to be a 30-year inquisition of nearly two dozen molecules that has engaged investigators worldwide. Historically, researchers have searched for a structural flaw in one of the collagen molecules to explain the cause of Marfan Syndrome. Using monoclonal antibodies, researchers have implicated microfibrils, the extracellular filaments that provide a matrix for the deposit of elastin during embryonic development.

Objective. To determine how well conventional radiographic findings can predict the presence of dural ectasia in Marfan patients.Design and patients. Twelve Marfan patients without dural ectasia and 21 Marfan patients with dural ectasia were included in the study. Five radiographic measurements were made of the lumbosacral spine: interpediculate distance, scalloping value, sagittal canal diameter, vertebral body width, and transverse process width.Results. The following measurements were significantly larger in patients with dural ectasia: interpediculate distances at L3-L4 levels (P<0.03); scalloping values at the L1 and L5 levels (P<0.05); sagittal diameters of the vertebral canal at L5-S1 (P<0.03); transverse process to width ratios at L2 (P<0.03). Criteria were developed for diagnosis of dural ectasia in Marfan patients. These included presence of one of the following: interpediculate distance at L4 >38.0 mm, sagittal diameter at S1 >18.0 mm, or scalloping value at L5 >5.5 mm.Conclusion. Dural ectasia in Marfan syndrome is commonly associated with several osseous changes that are observable on conventional radiographs of the lumbosacral spine. Conventional radiography can detect dural ectasia in patients with Marfan syndrome with a very high specificity (91.7%) but a low sensitivity (57.1%). (orig.)

Full Text Available Nearly 100 years ago, Antoine Marfan first described a recurrent systemic disorder of connective tissue characterized by overgrowth of the long bones (1. It took an additional 50 years before ocular and cardiovascular manifestations were associated with this disorder, now termed Marfan syndrome (MFS. MFS is an inherited connective tissue disorder transmitted as an autosomal dominant trait. This relatively common genetic condition affects approximately 2 to 3 per 10,000 individuals, without a particular gender, racial, geographic, or ethnic predilection (2. The disorder results from mutations in the fibrillin-1 (FBN1 gene located on chromosome 15q21.1(3. Approximately 15% of cases occur in the absence of a family history, representing new mutations; infact to date, over 550 mutations have been identified in patients with MFS and related connective tissue diseases. However, about a half of MFS cases do not possess mutations in the FBN1 gene...

We report a 33-year-old woman who had a 60-mm thoracic aneurysm of the ascending aorta with Marfan syndrome and effort angina due to compression of the right coronary artery (RCA) by the aneurysm. Surgery was performed using the Bentall procedure and a coronary artery bypass graft to the RCA. Postoperatively, coronary angiography showed that the coronary flow of the RCA was restored by removing the aneurysmal compression. The patient was discharged without angina on postoperative day 21.

We reviewed 50 patients with Marfan syndrome who underwent surgery for aortic root pathologies comprising a root aneurysm without (n = 25; group A) and with (n = 25; group B) dissection. Aortic root repair included Bentall (n = 37) and valve-sparing (n = 13) procedures. Hospital mortality was 4.0%. Twenty-two patients required 36 repeat surgeries on the distal aorta. The main indication for re-intervention was the dilation of the false lumen. In group A, the distal aorta was stable for up to 7 years, but new dissection developed in 5 (33.3%) of the 15 patients who were followed up for >7 years after the root repair. Actuarial survival including operative mortality was 88.1 and 65.0% at 10 and 20 years, respectively; groups A and B did not significantly differ. Rates of freedom from all-cause death, new dissection or repeated aortic surgery were 60.1, 44.5 and 26.0% at 5, 10 and 15 years, respectively. Group A was significantly better than group B. Prophylactic aortic root repair apparently reduces the likelihood of overall adverse events, but it cannot guarantee the prevention of further aortic dissection. A multidisciplinary approach is needed for patients with Marfan syndrome.

2012-01-01

Full Text Available Abstract Background The majority of Marfan syndrome (MFS cases is caused by mutations in the fibrillin-1 gene (FBN1, mapped to chromosome 15q21.1. Only few reports on deletions including the whole FBN1 gene, detected by molecular cytogenetic techniques, were found in literature. Results We report here on a female patient with clinical symptoms of the MFS spectrum plus craniostenosis, hypothyroidism and intellectual deficiency who presents a 1.9 Mb deletion, including the FBN1 gene and a complex rearrangement with eight breakpoints involving chromosomes 6, 12 and 15. Discussion This is the first report of MFS with a complex chromosome rearrangement involving a deletion of FBN1 and contiguous genes. In addition to the typical clinical findings of the Marfan syndrome due to FBN1 gene haploinsufficiency, the patient presents features which may be due to the other gene deletions and possibly to the complex chromosome rearrangement.

2007-01-01

Purpose: To compare the aortic compliance of the normal-sized aorta of adolescents with Marfan syndrome and healthy controls using MR measurements of the aortic distensibility and pulse wave velocity. Materials and Methods: Fourteen patients (median age: 15 [9-21] years) and 11 healthy subjects (23 [12-32] years) were examined at 1.5 T. The MR protocol included 2D steady-state free precession (SSFP)-CINE MRI of the aortic distensibility and PC-MRI of the pulse wave velocity. All measurements were positioned perpendicular to the descending aorta at the level of the diaphragm for assessing the changes in the aortic cross-sectional areas and additionally above and below this plane for assessing the pulse wave velocity. In addition contrast-enhanced 3D-MR angiography was performed in adolescents with Marfan syndrome to exclude morphologic changes and to prove normal-sized aorta. Results: Compared with control subjects, adolescents with Marfan syndrome had significantly decreased distensibility and significantly increased pulse wave velocity (χ 2 -test, p = 0.0002) using an age-related non-linear regression analysis. The related aortic compliance was significantly decreased (χ 2 -test, p = 0.0002). There was a good correlation between the two methods (r = 0.86). A low intraobserver variability was found for both methods (≤ 2 %). (orig.)

Moreover, VTE related to mutations in exons 24-32 (P = .021. Kaplan-Meier analysis corroborated an association of VTE with increased NT-proBNP (P<.001 and with mutations in exons 24-32 (P<.001.Marfan syndrome with causative FBN1 mutations is associated with an increased risk for arrhythmia, and affected persons may require life-long monitoring. Ventricular arrhythmia on electrocardiography, signs of myocardial dysfunction and mutations in exons 24-32 may be risk factors of VTE.

Non-cardiac manifestations of Marfan syndrome

Science.gov (United States)

2017-01-01

Because of the widespread distribution of fibrillin 1 in the body, Marfan syndrome (MFS) affects virtually every system. The expression of this single dominantly inherited gene is variable within a family, and between families. There is some genotype-phenotype correlation which is helpful in guiding long-term prognosis, and management. In general gene mutations have been reported in clusters, with those having mainly ocular manifestations occurring in exons 1 to 15 of this 65-exon gene; those causing cardiac problems often involving cysteine replacement in a calcium binding EGF-like sequence; the most severe mutations occurring in exons 25–32, causing neonatal MFS diagnosed at birth, and severe enough to cause death frequently before the age of 2. Other correlations will certainly be found in future. This condition is progressive, and the manifestations unfold according to age. For example, if the lens is going to dislocate this usually occurs by age 10; scoliosis usually presents itself between the ages of 8 and 15; height should be monitored carefully between the onset of puberty and cessation of growth approximately age 17 or 18. Holistic care should be offered by one doctor who oversees the patient’s welfare. This should be a paediatrician, paediatric cardiologist, or general practitioner in the case of an affected child. Thereafter, the physician in charge of the most seriously affected system should be aware that other systems need to be managed through a referral network. PMID:29270372

The Marfan syndrome, an autosomal dominant connective tissue disorder, is manifested by abnormalities in the cardiovascular, skeletal, and ocular systems. Recently, fibrillin, an elastic-associated microfibrillar glycoprotein, has been linked to the Marfan syndrome, and fibrillin mutations in affected individuals have been documented. In this study, genetic linkage analysis with fibrillin-specific markers was used to establish the prenatal diagnosis in an 11-wk-gestation fetus in a four-generation Marfan kindred. At birth, skeletal changes suggestive of the Marfan syndrome were observed. Reverse transcription-PCR amplification of the fibrillin gene mRNA detected a deletion of 123 bp in one allele in affected relatives. This deletion corresponds to an exon encoding an epidermal growth factor-like motif. Examination of genomic DNA showed a G[yields]C transversion at the +1 consensus donor splice site. 45 refs., 7 figs.

After 3.2 mm clear cornea incision and continuous curvilinear capsulorhexis (CCC), 2 - 4 disposable nylon iris hooks were inserted through the stab incisions and placed in the capsulorhexis to support the capsule and enlarged the CCC. Following irrigation/aspiration, a MCTR with suture in its eyelet was placed in the capsule bag. After tightening and tying the suture of MCTR, the capsular bag was centered and fixed. A foldable AcrySof one-piece intraocular lens (IOL) was then placed in the capsule bag. Twelve months after the operation, the best corrected visual acuity was >/= 0.8 in six eyes and 0.7 in one eye. The scheimpflug images obtained from the Pentacam demonstrated that the IOL were well centered. UBM showed that all the MCTR and the haptics of the IOL were in the capsule bag, the eyelet of the MCTR was rested stably between the capsulorhexis margin and the iris. The retroillumination photograph indicated that only one eye had obvious posterior capsular opacification. No intraoperative and postoperative complications such as prolapse of vitreous and retina detachment was occurred. The iris hooks can provide excellent intraoperative capsule-lens stability and facilitate the manipulation during operation. MCTR allows additional suture fixation to the eye wall without damaging the capsular bag and maintains the long-term stability of the intraocular lens. Furthermore, MCTR is helpful for avoiding dislocation of the IOL due to progressive weakening of the zonular fibers in some patients and provides long-term safety.

The main cardiovascular alteration in Marfan syndrome (MFS) is the formation of aortic aneurysms in which augmented TGF-β signaling is reported. However, the primary role of TGF-β signaling as a molecular link between the genetic mutation of fibrillin-1 and disease onset is controversial. The compartmentalization of TGF-β endocytic trafficking has been shown to determine a signaling response in which clathrin-dependent internalization leads to TGF-β signal propagation, and caveolin-1 (CAV-1) associated internalization leads to signal abrogation. We here studied the contribution of endocytic trafficking compartmentalization to increased TGF-β signaling in vascular smooth muscle cells (VSMC) from MFS patients. We examined molecular components involved in clathrin- (SARA, SMAD2) and caveolin-1- (SMAD7, SMURF2) dependent endocytosis. Marfan VSMC showed higher recruitment of SARA and SMAD2 to membranes and their increased interaction with TGF-β receptor II, as well as higher colocalization of SARA with the early endosome marker EEA1. We assessed TGF-β internalization using a biotinylated ligand (b-TGF-β), which colocalized equally with either EEA1 or CAV-1 in VSMC from Marfan patients and controls. However, in Marfan cells, colocalization of b-TGF-β with SARA and EEA1 was increased and accompanied by decreased colocalization with CAV-1 at EEA1-positive endosomes. Moreover, Marfan VSMC showed higher transcriptional levels and membrane enrichment of RAB5. Our results indicate that increased RAB5-associated SARA localization to early endosomes facilitates its TGF-β receptor binding and phosphorylation of signaling mediator SMAD2 in Marfan VSMC. This is accompanied by a reduction of TGF-β sorting into multifunctional vesicles containing cargo from both internalization pathways. Copyright © 2017 Elsevier B.V. All rights reserved.

Rupture and dissection of aortic root aneurysms remain the leading causes of death in patients with the Marfan syndrome, a hereditary connective tissue disorder that affects 1 in 5000 individuals worldwide. In the present study, we use a Marfan mouse model (Fbn1(C1039G/+)) to investigate the biological importance of apoptosis during aneurysm development in Marfan syndrome. Using in vivo single-photon emission computed tomographic-imaging and ex vivo autoradiography for Tc99m-annexin, we discovered increased apoptosis in the Fbn1(C1039G/+) ascending aorta during early aneurysm development peaking at 4 weeks. Immunofluorescence colocalization studies identified smooth muscle cells (SMCs) as the apoptotic cell population. As biological proof of concept that early aortic wall apoptosis plays a role in aneurysm development in Marfan syndrome, Fbn1(C1039G/+) mice were treated daily from 2 to 6 weeks with either (1) a pan-caspase inhibitor, Q-VD-OPh (20 mg/kg), or (2) vehicle control intraperitoneally. Q-VD-OPh treatment led to a significant reduction in aneurysm size and decreased extracellular matrix degradation in the aortic wall compared with control mice. In vitro studies using Fbn1(C1039G/+) ascending SMCs showed that apoptotic SMCs have increased elastolytic potential compared with viable cells, mostly because of caspase activity. Moreover, in vitro (1) cell membrane isolation, (2) immunofluorescence staining, and (3) scanning electron microscopy studies illustrate that caspases are expressed on the exterior cell surface of apoptotic SMCs. Caspase inhibition attenuates aneurysm development in an Fbn1(C1039G/+) Marfan mouse model. Mechanistically, during apoptosis, caspases are expressed on the cell surface of SMCs and likely contribute to elastin degradation and aneurysm development in Marfan syndrome. © 2014 American Heart Association, Inc.

Full Text Available Marfan syndrome (MFS is a systemic hereditable disorder of the connective tissue with mainly cardiovascular manifestations, such as aortic dilatation and dissection. We describe a case of a 32-year-old Caucasian woman, clinically asymptomatic with MFS who presented for genetic consultation to prevent the transmission of disease to her offspring. She underwent controlled ovarian stimulation (COH, in vitro fertilization (IVF combined with preimplantation genetic diagnosis (PGD, and a singleton pregnancy with positive fetal heart rate was revealed. At 34 weeks’ gestation she delivered vaginally a healthy premature male infant weighting 2440 gr. The patient remained asymptomatic during pregnancy, delivery, and 3 months postpartum. It is has to be mentioned that the availability of PGD is essential to prevent the transmission of disease to the next generation.

Rationale A number of randomized trials are underway, which will address the effects of angiotensin receptor blockers (ARBs) on aortic root enlargement and a range of other end points in patients with Marfan syndrome. If individual participant data from these trials were to be combined, a meta-analysis of the resulting data, totaling approximately 2,300 patients, would allow estimation across a number of trials of the treatment effects both of ARB therapy and of β-blockade. Such an analysis would also allow estimation of treatment effects in particular subgroups of patients on a range of end points of interest and would allow a more powerful estimate of the effects of these treatments on a composite end point of several clinical outcomes than would be available from any individual trial. Design A prospective, collaborative meta-analysis based on individual patient data from all randomized trials in Marfan syndrome of (i) ARBs versus placebo (or open-label control) and (ii) ARBs versus β-blockers will be performed. A prospective study design, in which the principal hypotheses, trial eligibility criteria, analyses, and methods are specified in advance of the unblinding of the component trials, will help to limit bias owing to data-dependent emphasis on the results of particular trials. The use of individual patient data will allow for analysis of the effects of ARBs in particular patient subgroups and for time-to-event analysis for clinical outcomes. The meta-analysis protocol summarized in this report was written on behalf of the Marfan Treatment Trialists' Collaboration and finalized in late 2012, without foreknowledge of the results of any component trial, and will be made available online (http://www.ctsu.ox.ac.uk/research/meta-trials).

Aortic dilatation in Marfan syndrome (MFS) is progressive. It is associated with oxidative stress and endothelial dysfunction that contribute to the early acute dissection of the vessel and can result in rupture of the aorta and sudden death. We evaluated the participation of the glutathione (GSH) system, which could be involved in the mechanisms that promote the formation and progression of the aortic aneurysms in MFS patients. Aortic aneurysm tissue was obtained during chest surgery from eight control subjects and 14 MFS patients. Spectrophotometrical determination of activity of glutathione peroxidase (GPx), glutathione-S-transferase (GST), glutathione reductase (GR), lipid peroxidation (LPO) index, carbonylation, total antioxidant capacity (TAC), and concentration of reduced and oxidized glutathione (GSH and GSSG respectively), was performed in the homogenate from aortic aneurysm tissue. LPO index, carbonylation, TGF-β1, and GR activity were increased in MFS patients (p < 0.04), while TAC, GSH/GSSG ratio, GPx, and GST activity were significantly decreased (p < 0.04). The depletion of GSH, in spite of the elevated activity of GR, not only diminished the activity of GSH-depend GST and GPx, but increased LPO, carbonylation and decreased TAC. These changes could promote the structural and functional alterations in the thoracic aorta of MFS patients.

We report a child and her mother affected by Marfan syndrome. The child presented with a phenotype of neonatal Marfan syndrome, revealed by acute and refractory heart failure, finally leading to death within the first 4 months of life. Her mother had a common clinical presentation. Genetic analysis revealed an inherited FBN1 mutation. This intronic mutation (c.6163+3_6163+6del), undescribed to date, leads to exon 49 skipping, corresponding to in-frame deletion of 42 amino acids (p.Ile2014_Asp2055del). FBN1 next-generation sequencing did not show any argument for mosaicism. Association in the same family of severe neonatal and classical Marfan syndrome illustrates the intrafamilial phenotype variability.

To investigate surgical outcomes and complications of scoliosis associated with Marfan syndrome. Inclusion criteria were patients who were 10-20 years of age, had a diagnosis of Marfan syndrome by the Ghent nosology, had scoliosis and had undergone spinal fusion, and had at least 2 years of postoperative follow-up. The medical records of all patients were reviewed for age at the time of surgery, surgical procedures performed, instrumentation type, estimated blood loss (EBL) during surgery, operation time and complications related to surgery. Health-related quality-of-life measures (obtained with the SRS-22 Questionnaire before operation and at the last clinical follow-up) were also recorded. Patients were analyzed as two different groups, Group 1 and Group 2, according to the different approaches employed. Patients receiving combined anterior and posterior surgery were assigned to Group 1 and those who received posterior-only surgery to Group 2. Group 1 consisted of 30 patients (14 males, 16 females) with a mean age at surgery of 16.8 years (range: 10-20 years). Complications in Group 1 included two cases of instrumentation loosening with one removed, one case of instrumentation breakage and one case of chylothorax and hemothorax during video assisted thoracoscopic release. 66 patients (28 males, 38 females) with a mean age at surgery of years 16.4 years (range: 10-20 years) were included in Group 2. Complications in Group 2 included six cases of cerebro-spinal fluid leak, one case of deep wound infection secondary to cerebro-spinal fluid leak, one case of leg weakness and one case of pleural rupture cause by misplacement of pedicle screw. There is no difference of age at surgery, preoperative Cobb angles, and SRS-22 total scores (3.0 vs. 3.1) between the two groups (P > 0.05). Group 1 yielded larger correction rate than Group 2 for both thoracic (62.5 % vs. 56.2 %) and lumbar scoliosis (68.3 % vs. 62.7 %). Loss of correction was similar between the two

To report the distribution of macular and optic nerve topography in the eyes of individuals with Marfan syndrome aged 8-56 years using spectral domain optical coherence tomography (SD-OCT). Thirty-three patients with Marfan syndrome underwent a full eye examination including slit-lamp biomicroscopy, indirect ophthalmoscopy, and axial length measurement; and SD-OCT measurements of the retinal nerve fiber layer (RNFL) and macular thickness. For patients between the ages of 8 and 12 years, the average RNFL thickness is 98 ± 9 μm, the vertical cup to disc (C:D) ratio is 0.50 ± 0.10, the central subfield thickness (CST) is 274 ± 38 μm, and the macular volume is 10.3 ± 0.6 mm 3 . For patients between the ages of 13 and 17 years, the average RNFL is 86 ± 16 μm, the vertical C:D ratio is 0.35 ± 0.20, the CST is 259 ± 15 μm, and the macular volume is 10.1 ± 0.5 mm 3 . For patients 18 years or older, the average RNFL is 89 ± 12 μm, the vertical C:D ratio is 0.46 ± 0.18, the CST is 262 ± 20 μm, and the macular volume is 10.2 ± 0.4 mm 3 . When the average RNFL data are compared to a normative, age-adjusted database, 6 of 33 (18%) were thinner than the 5% limit. This study reports the distribution of SD-OCT data for patients with Marfan syndrome. Compared to a normative database, 18% of eyes with Marfan syndrome had RNFL thickness < 5% of the population.

health care team at the Hamburg Marfan center gives a personal account of his or her contribution in the management of patients with MFS. The authors show how, with the support of health care managers, key team members organize themselves in an organizational structure to create a common meaning, to maximize therapeutic success for patients with MFS. First, we show how the initiative and collaboration of patient representatives, scientists, and physicians resulted in the foundation of Marfan centers, initially in the US and later in Germany, and how and why such centers evolved over time. Then, we elucidate the three main structural elements; a team of coordinators, core disciplines, and auxiliary disciplines of health care. Moreover, we explain how a multidisciplinary health care team integrates into many other health care structures of a university medical center, including external quality assurance; quality management system; clinical risk management; center for rare diseases; aorta center; health care teams for pregnancy, for neonates, and for rehabilitation; and in structures for patient centeredness. We provide accounts of medical goals and standards for each core discipline, including pediatricians, pediatric cardiologists, cardiologists, human geneticists, heart surgeons, vascular surgeons, vascular interventionists, orthopedic surgeons, ophthalmologists, and nurses; and of auxiliary disciplines including forensic pathologists, radiologists, rhythmologists, pulmonologists, sleep specialists, orthodontists, dentists, neurologists, obstetric surgeons, psychiatrist/psychologist, and rehabilitation specialists. We conclude that a multidisciplinary health care team is a means to maximize therapeutic success. Keywords: multidisciplinary, Marfan syndrome, health care, team, profession, sociology, management

To describe the clinical cardiac manifestations and temporal evolution of Marfan syndrome in children; to estimate the incidence of annuloaortic ectasia and mitral valve prolapse; and to evaluate tolerability and efficacy of beta-blockers in these patients. During one year, 21 children with Marfan syndrome underwent serial clinical and echocardiographic examinations. Echocardiograms assessed: the presence of mitral valve prolapse, aortic root diameter, mitral and aortic valves regurgitation, and aortic enlargement during beta-blocker therapy. Eleven patients had two measurements of the aortic root taken one year apart. The children were asymptomatic throughout the study. Mitral prolapse was found in 11 (52%) children. Annuloaortic ectasia occurred in 16 (76%) patients and found to be mild in 42.8%, moderate in 9.5%, and severe in 23.8%. One of these patients underwent aortic valve replacement and repair of the ascending aorta by the Bentall-De Bono technique, with good results. Heart rate decreased by 13.6% (from 85 to 73 bpm; p < 0.009) with the use of beta-blockers; however, aortic root diameter increased by 1.4 mm/year (p < 0.02). One child could not be given beta-blockers due to bronchial asthma, and no significant side effects were observed in the remaining children, including one who also had bronchial asthma. The children remained asymptomatic throughout the study, the use of beta-blockers led to a significant decrease in heart rate, and no significant adverse effects were observed. Contrary to the literature, incidence of annuloaortic ectasia was high among the study population, greater than that of mitral valve prolapse, even during beta-blocker therapy.

The authors report on the assessment of an anthropogenic mummy of a young man from the Capuchin Catacombs of Palermo, Sicily, tentatively dated from the mid- to late 19 th century AD. The mummy was investigated by full-body CT examination. CT images clearly showed aortic dissection classified as Stanford-A. Due to the relation of aortic dissection to inherited connective tissue diseases in young people, such as Marfan syndrome, conspicuous and pathological findings possibly indicating the presence of underlying Marfan syndrome were assessed. Several systemic features were scored that supported the presence of underlying Marfan syndrome in this mummy. These findings were: pectus carinatum and chest asymmetry, dural ectasia, protrusio acetabuli, dolichocephaly, down-slanting palpebral fissures, malar hypoplasia and (probable) reduced elbow extension. Aortic dissection, a cardinal feature of Marfan syndrome, turned out to be the diagnostic key for the paleoradiological diagnosis of this disease. The demonstrated CT findings contribute to the spectrum of cardiovascular diseases and inherited connective tissue disease in the fields of paleopathology and paleoradiology.

Technical variations of the David reimplantation valve-sparing aortic root replacement (V-SARR) procedure have been proposed to be advantageous in patients with connective tissue disease, such as the Marfan syndrome (MFS). We report results of a Marfan cohort treated exclusively with the non-modified David I procedure. Forty-eight Marfan patients (25 males, mean age 33 ± 12 years, range 15-62 years) underwent the original variant of the David V-SARR (David I) between 1997 and 2013. Forty-two operations (88%) were performed as elective procedures for aortic root aneurysms and six for acute dissections (12%). Seventeen had aortic regurgitation (AR) grades ≥2+ preoperatively, and 3 had AR >2+. No patients with severe AR (4+) were selected for V-SARR. Three full or hemi-arch replacements were performed. Patients who were operated on using a variation of the David I or David II procedure were excluded. Mean prosthesis size was 28 ± 3 mm (18-30 mm). Mean clinical and echocardiographic follow-up (98% complete) was 3.8 ± 3.7 years with a cumulative follow-up of 178 patient-years. The early mortality rate was 2% (one hospital death). The survival rate was 98% (95% confidence 84-99%) at 4 years and 90% (57-98%) at 8 years with 5 patients at risk at 10 years. The rate of freedom from root or valve reoperation was 97% (79-99%) and 97% (79-99%) at 4 and 8 years, respectively. Only one patient required mechanical aortic valve replacement for progression of AR. Despite potential theoretical drawbacks of the David I V-SARR technique without neo-sinuses or a neo-sinotubular junction, it results in a favourable mid-term outcome in Marfan patients and compares well with reported results of different modifications of David V-SARR. © The Author 2014.

[Sudden death and cardiovascular complications in Marfan syndrome: impact of surgical intervention].

Science.gov (United States)

Ohtsubo, Satoshi; Itoh, Tsuyoshi

2005-07-01

Marfan syndrome is an autosomal dominant disorder of connective tissue characterized by abnormalities involving the skeletal, ocular, and cardiovascular systems. The cardiovascular complications of the syndrome lead to a reduced life expectancy for affected individuals if left untreated. Major cause of death include acute aortic dissection, aortic rupture, and sudden death, which resulted from congenital vascular fragility. Such life-threatening complications in Marfan syndrome can be managed effectively, by routine aortic imaging, beta-adrenergic blockade, and prophylactic replacement of the aortic root before the diameter exceeds 5.0 to 5.5 mm. Valve preserving aortic root reconstruction yielded improved postoperative quality of life compared with Bentall operation, by reducing late complications related to anticoagulants. It should be carried out before onset of aortic regurgitation for long-term native valve durability.

The study aim was to compare long-term results of Marfan syndrome (MFS) patients affected by aortic root disease undergoing aortic root replacement with the Bentall or David operation. Since 1994, a total of 59 patients has been followed at the authors' Marfan Center, having undergone either a Bentall operation (Bentall group, n = 30) or a David operation (David group, n = 29). No operative mortality was recorded. After 20 years (mean follow up 97 ± 82 months; range 1 to 369 months) no prosthesis-related major bleeding or thromboembolic events had been observed; the 20-year survival was 94 ± 6% in the Bentall group, and 100% in the David group (p = 0.32). Freedom from reintervention for aortic valve dysfunction was 100% in the Bentall group, and 75 ± 13% in the David group (p = 0.04). This inter-group difference became relevant after the first eight-year period of follow-up, and was mainly associated with a particular familiar genetic phenotype involving three out of four reoperated patients. Freedom from all-cause death, myocardial infarction, stroke, prosthetic valve-related complications, and reintervention on any aortic segment was 69 ± 12% in the Bentall group, and 67 ± 14% in the David group (p = 0.33). The Bentall and David operations are both associated with satisfactory long-term results in MFS patients. The low rate of valve prosthesis-related complications suggested that the Bentall operation would continue to be a standard surgical treatment. The reimplantation technique, adopted for less-dilated aortas, provides satisfactory freedom from reoperation. Careful attention should be paid to the reimplantation technique in patients affected by a serious familiar genetic phenotype.

Introduced by DePaulis in 2000, the Gelweave Valsalva graft (Sulzer Vascutek, Refrewshire, Scotland) is a modified Dacron conduit (DuPont, Wilmington, DE), with prefashioned sinuses of Valsalva. The aim of this study was to evaluate the mid-term results of the reimplantation valve-sparing aortic root replacement using the Gelweave Valsalva prosthesis in Marfan syndrome patients. A retrospective review was performed of 35 patients with Marfan syndrome in four centers who underwent the reimplantation valve-sparing aortic root replacement using the Gelweave Valsalva prosthesis. The patients were predominantly men, with a mean age of 36.5 +/- 12.6 years (range, 14 to 62 years). Two patients presented with acute type A dissections and underwent emergent operations. Elective hemiarch reconstruction using hypothermic circulatory arrest was required in 11 patients. Aortic valve cusp repair was performed in 2 patients. There were no operative or hospital deaths, and no patients died during follow-up. The mean follow-up was 19 months (range, 1 to 60 months). Significant (>2+) aortic insufficiency (AI), requiring aortic valve replacement, developed in 3 patients during follow-up that requiring aortic valve replacement. The 5-year freedom from reoperation owing to structural valve deterioration was 88.9% +/- 8.1%. There were no episodes of clinically significant thromboembolism. Reimplantation valve-sparing aortic root replacement with the Gelweave Valsalva prosthesis in Marfan patients provides satisfactory mid-term results, thus encouraging further use of this type of repair. However, long-term results are needed in order to define the durability of this technique.

We conducted a pilot study to evaluate the psychological effects and consequences of Marfan syndrome in 17 patients between 16 and 35 years of age. Through a semi-structured interview, we investigated how the patients coped daily with Marfan syndrome and evaluated the impact of the disease on specific items such as schooling, occupational choices, self-image, and social behaviour. A second part of the study consisted of a battery of standardised psychological tests to evaluate the patients' anxiety and depression levels and coping styles. The following psychological tests were used: State and Trait Anxiety Inventory (STAI), Beck Depression Inventory (BDI), and the Utrecht Coping List (UCL). The interviews showed that the disease represented a significant burden on the daily physical activities of the patients, as well as on their schooling and job opportunities. During childhood, most of them were insensitively teased by peers because of their typical phenotypic features. This had its consequences on their social behaviour in that they are all more introvert. In the female patients, the risk associated with child bearing represented a major concern. Most patients emphasised the need for accurate information about the illness immediately after knowing the diagnosis and all found psychological support helpful. Depression and anxiety levels were higher in the female than in the male group, without being significantly different from the normal population. Nevertheless, most patients have come to terms with their disease and consider themselves happy most of the time. PMID:9610804

No beneficial effect of general and specific anti-inflammatory therapies on aortic dilatation in Marfan mice.

Romy Franken

Full Text Available AIMS: Patients with Marfan syndrome have an increased risk of life-threatening aortic complications, mostly preceded by aortic dilatation. In the FBN1(C1039G/+ Marfan mouse model, losartan decreases aortic root dilatation. We recently confirmed this beneficial effect of losartan in adult patients with Marfan syndrome. The straightforward translation of this mouse model to man is reassuring to test novel treatment strategies. A number of studies have shown signs of inflammation in aortic tissue of Marfan patients. This study examined the efficacy of anti-inflammatory therapies in attenuating aortic root dilation in Marfan syndrome and compared effects to the main preventative agent, losartan. METHODS AND RESULTS: To inhibit inflammation in FBN1(C1039G/+ Marfan mice, we treated the mice with losartan (angiotensin II receptor type 1 inhibitor, methylprednisolone (corticosteroid or abatacept (T-cell-specific inhibitor. Treatment was initiated in adult Marfan mice with already existing aortic root dilatation, and applied for eight weeks. Methylprednisolone- or abatacept-treated mice did not reveal a reduction in aortic root dilatation. In this short time frame, losartan was the only treatment that significantly reduced aorta inflammation, transforming growth factor-beta (TGF-β signaling and aortic root dilatation rate in these adult Marfan mice. Moreover, the methylprednisolone-treated mice had significantly more aortic alcian blue staining as a marker for aortic damage. CONCLUSION: Anti-inflammatory agents do not reduce the aortic dilatation rate in Marfan mice, but possibly increase aortic damage. Currently, the most promising therapeutic drug in Marfan syndrome is losartan, by blocking the angiotensin II receptor type 1 and thereby inhibiting pSmad2 signaling.

Angiotensin, transforming growth factor β and aortic dilatation in Marfan syndrome: Of mice and humans

Full Text Available Marfan syndrome is consequent upon mutations in FBN1, which encodes the extracellular matrix microfibrillar protein fibrillin-1. The phenotype is characterised by development of thoracic aortic aneurysm. Current understanding of the pathogenesis of aneurysms in Marfan syndrome focuses upon abnormal vascular smooth muscle cell signalling through the transforming growth factor beta (TGFβ pathway. Angiotensin II (Ang II can directly induce aortic dilatation and also influence TGFβ synthesis and signalling. It has been hypothesised that antagonism of Ang II signalling may protect against aortic dilatation in Marfan syndrome. Experimental studies have been supportive of this hypothesis, however results from multiple clinical trials are conflicting. This paper examines current knowledge about the interactions of Ang II and TGFβ signalling in the vasculature, and critically interprets the experimental and clinical findings against these signalling interactions.

Marfan syndrome (MFS) is a rare, autosomal-dominant, multisystem disorder, presenting with skeletal, ocular, skin, and cardiovascular symptoms. Significant clinical overlap with other systemic connective tissue diseases, including Loeys-Dietz syndrome (LDS), Shprintzen-Goldberg syndrome (SGS), and the MASS phenotype, has been documented. In MFS and LDS, the cardiovascular manifestations account for the major cause of patient morbidity and mortality, rendering them the main target for therapeutic intervention. Over the past decades, gene identification studies confidently linked the aforementioned syndromes, as well as nonsyndromic aneurysmal disease, to genetic defects in proteins related to the transforming growth factor (TGF)-β pathway, greatly expanding our knowledge on the disease mechanisms and providing us with novel therapeutic targets. As a result, the focus of the developing pharmacological treatment strategies is shifting from hemodynamic stress management to TGF-β antagonism. In this review, we discuss the insights that have been gained in the molecular biology of MFS and related disorders over the past 25 years. © 2016 WILEY PERIODICALS, INC.

We report the case of a 48-year-old Japanese man who suffered from Marfan syndrome with severe aortic regurgitation, mitral regurgitation and rapid atrial fibrillation, which were aggravated by hyperdynamic circulatory conditions associated with coexistent Basedow's disease. Furthermore, concurrence of Arg353Gln polymorphism-related factor VII deficiency was discovered at the preoperative assessments. Both of his two brothers suffered from Marfan syndrome; however they had no findings of Arg353Glu polymorphism-related factor VII deficiency or Basedow's disease. After normalization of thyroid function, he had successfully the operations of Bentall procedure: a composite prosthetic graft: replacement of both the ascending aorta and aortic valve, and mitral valve annuloplasty. No specific therapy such as fresh frozen plasma or factor VII replacement therapy was required. He completely returned to his business work 6 weeks after the operation. Concurrence of Marfan syndrome and factor VII deficiency induced by two-hit genomic abnormalities and furthermore Basedow's disease, which significantly compromised the pathophysiological condition of Marfan syndrome, is extremely rare.

It has been shown that losartan reduces aortic dilatation in patients with Marfan syndrome. However, treatment response is highly variable. This study investigates losartan effectiveness in genetically classified subgroups. In this predefined substudy of COMPARE, Marfan patients were randomized to daily receive losartan 100 mg or no losartan. Aortic root dimensions were measured by MRI at baseline and after 3 years. FBN1 mutations were classified based on fibrillin-1 protein effect into (1) haploinsufficiency, decreased amount of normal fibrillin-1, or (2) dominant negative, normal fibrillin-1 abundance with mutant fibrillin-1 incorporated in the matrix. A pathogenic FBN1 mutation was found in 117 patients, of whom 79 patients were positive for a dominant negative mutation (67.5%) and 38 for a mutation causing haploinsufficiency (32.5%). Baseline characteristics between treatment groups were similar. Overall, losartan significantly reduced aortic root dilatation rate (no losartan, 1.3±1.5 mm/3 years, n=59 versus losartan, 0.8±1.4 mm/3 years, n=58; P=0.009). However, losartan reduced only aortic root dilatation rate in haploinsufficient patients (no losartan, 1.8±1.5 mm/3 years, n=21 versus losartan 0.5±0.8 mm/3 years, n=17; P=0.001) and not in dominant negative patients (no losartan, 1.2±1.7 mm/3 years, n=38 versus losartan 0.8±1.3 mm/3 years, n=41; P=0.197). Marfan patients with haploinsufficient FBN1 mutations seem to be more responsive to losartan therapy for inhibition of aortic root dilatation rate compared with dominant negative patients. Additional treatment strategies are needed in Marfan patients with dominant negative FBN1 mutations. http://www.trialregister.nl/trialreg/index.asp; Unique Identifier: NTR1423. © 2015 American Heart Association, Inc.

Screening for mutations in the FBN1 cDNA from Marfan patient cell strains has detected mutations in only 10-15% of patients. In an attempt to explain this poor detection rate, we examined FBN1 allele expression and fibrillin synthesis by 26 cell strains from Marfan patients. DNA from the patients and 10 controls was assessed for the presence of a polymorphic Rsa I restriction site in the 3{prime} untranslated region of the FBN1 gene. Twelve of 26 patient and 5 of 10 control DNAs were heterozygous. Fibroblast RNA from the heterozygous cell strains was reverse-transcribed and subsequently PCR amplified using a [{sup 32}P]-labelled primer, digested with Rsa I and analyzed. Although 3 samples showed no transcript from one allele by ethidium bromide staining, a Betagen scanner detected low levels (10-15%) of that allele. In addition, there was unequal expression of the two alleles in three other patients; for example, only 30% expression from one allele. The remaining patients and the controls had equal expression of each allele. Fibrillin protein synthesis by fibroblasts from these heterozygous patients was also examined. After a 30 minute pulse with [{sup 35}S]-cysteine, cell lysates were collected and proteins analyzed by SDS-PAGE. The amount of fibrillin produced relative to a reference protein was determined using a Betagen scanner. Fibrillin protein synthesis was reduced in 2 of the 3 patients with very low RNA production from one of the FBN1 alleles. All other Marfan and control cell strains showed normal amounts of fibrillin synthesized. The low expression levels from one allele may contribute to, but not fully account for, the low detection rate of FBN1 mutations. Interestingly, protein synthesis levels were not affected in 4 of 6 cell strains demonstrating low levels of RNA expression.

Stanford type A aortic dissection is a rare phenomenon with high short-term mortality and clinical manifestations that can make differential diagnosis a lengthy process requiring several diagnostic examinations. Based on a case report, the aim is to highlight the importance of physical examination in the initial management of these patients and of rapid access to a surgical center. A brief review follows on the diagnosis and treatment of ascending aortic dissection, and its specific nature in Marfan syndrome. A 33-year-old man was admitted to the emergency department of a district hospital with chest and back pain associated with vomiting, 20 hours after symptom onset. Initial physical examination revealed an aortic systolic murmur and musculoskeletal morphological abnormalities compatible with Marfan syndrome. Given suspected aortic dissection, a transthoracic echocardiogram was immediately performed, which showed an extensive intimal flap originating at the sinotubular junction. He was transferred to the cardiothoracic surgery department of a referral hospital where he was treated by a Bentall procedure. In this case, careful physical examination during initial assessment raised the suspicion that this patient was in a high-risk group for aortic dissection, thus avoiding unnecessary and lengthy exams. This diagnosis requires emergent surgical treatment, and so direct contact in real time between those making in the diagnosis and the surgeon is essential, as well as protocols governing immediate access to a surgical center.

A case of Marfans syndrome is described in which progressive neurological signs and symptoms were produced by flexion of the head. Radiological examinations revealed hypermotility between the atlas and axis, as well as compression of the medulla oblongata by the odontoid process on flexion, since low positioned cerebellar tonsils prevented dorsal shift of the oblongata. The signs and symptoms disappeared after occipitocervical internal transfixation. (orig.)

Marfan syndrome is an autosomal dominant connective tissue disorder, and mutations in the FBN1 and TGFBR2 genes have been identified in probands with MFS and related phenotypes. Using DHPLC and sequencing, we studied the mutation spectrum in 65 probands with Marfan syndrome and related phenotypes. A total of 24 mutations in FBN1 were identified, of which 19 (nine missense, six frameshift, two nonsense and two affecting splice junctions) were novel. In the remaining 41 probands, six were identified to have novel TGFBR2 mutations (one frameshift and five missense mutations). All novel mutations found in this study were confirmed to be absent in 50 unrelated normal individuals of the same ethnic background. In probands who fulfilled the Ghent criteria (n = 16), mutations in FBN1 were found in 81% of cases. None of those with TGFBR2 mutations fulfilled the Ghent criteria. Novel missense mutations of unknown significance were classified according to the latest ACMG guidelines and their likelihood to be causative was evaluated.

We performed surgical repair of a giant left coronary ostial aneurysm after aortic root replacement using composite valve graft (modified Bentall procedure) in a patient with Marfan syndrome. Aneurysmal formation in the left main stem itself is very rare. In order to avoid mobilizing the coronary ostium from severe adhesions after previous surgery and to reduce the tension on the anastomosis, the left main trunk was reconstructed using an interposition Dacron graft. In aortic root surgeries in Marfan patients, the size of the side hole on the composite graft should be kept relatively small to fit the diameter of the native coronary arteries for prevention of coronary buttons from forming aneurysms at the level of the coronary button anastomosis. In addition, close observation to the coronary button anastomosis is indispensable in postoperative check-up.

Marfan syndrome is a dominantly inherited connective tissue disorder with a wide range of phenotypic severity. The condition is the result of mutations in FBN1, a large gene composed of 65 exons encoding the fibrillin-1 protein. While mutations causing classic manifestations of Marfan syndrome have been identified throughout the FBN1 gene, the six previously characterized mutations resulting in the severe, perinatal lethal form of Marfan syndrome have clustered in exons 24-32 of the gene. We screened 8 patients with either neonatal Marfan syndrome or severe cardiovascular complications of Marfan syndrome for mutations in this region of the gene. Using intron-based exon-specific primers, we amplified exons 23-32 from genomic DNAs, screened these fragments by single-stranded conformational polymorphism analysis, and sequenced indicated exons. This analysis documented mutations in exons 25-27 of the FBN1 mutations in 6 of these patients. These results, taken together with previously published FBN1 mutations in this region, further define the phenotype associated with mutations in exons 24-32 of the FBN1 gene, information important for the development of possible diagnostic tests and genetic counseling. 49 refs., 4 figs., 2 tabs.

Aortic valve sparing root surgery for Marfan syndrome.

2017-11-01

Aortic valve sparing root surgery (AVSRS) is a safe and durable alternative for patients with dilated roots or pure aortic regurgitation (AR), which avoids the risks of anticoagulation or valvular degeneration with prosthetic valves. Notwithstanding the theoretical challenges of greater tissue fragility in Marfan syndrome (MFS), AVSRS has been demonstrated to have equal outcomes in this condition as it does in those without MFS. The benefits of retaining the native aortic valve in this generally younger age group extend beyond those of avoiding the inconvenience and complications of prolonged exposure to anticoagulants and include ease of management for future aortic, cardiac and non-cardiac procedures which are the norm for these patients. The essential principles of AVSRS in MFS do not differ from those for the rest of the population. Successful repair and durable valve function depend on a sound understanding of the close interaction between the structure and function of this exquisitely designed piece of engineering. We are fortunate to have numerous tools in our surgical armamentarium to preserve these valves. It is the purpose of this paper to demystify the complex structure-function interactions of the aortic valve, thereby gaining an intuition for AVSRS. We will also elaborate on specific technical details of established techniques that we have found successful in preserving the normal function of these valves in the long term.

Marfan patients with aortic root aneurysm are typically treated with the Bentall procedure, though aortic valve-sparing procedures (AVSPs) are also possible. The study aim was to compare the authors' experience with two such techniques performed at their institution, namely a reimplantation according to David (David I) and remodeling according to Yacoub. Between 1996 and 2009, a total of 37 Marfan patients underwent an AVSP at the authors' institution. Of these patients, 25 (mean age 32 +/- 14.9 years) underwent surgery according to David (group D), and 12 (mean age 35 +/- 10.9 years) according to Yacoub (group Y). The patients underwent both clinical and echocardiographic follow up examinations at a mean of 42.0 +/- 36.4 months after surgery. One patient from each group had moved abroad and was lost to follow up. The remaining 35 patients were alive at follow up, and none presented with any major neurological or bleeding complications. In addition, no significant differences were noted between the groups in terms of NYHA classification, left ventricular function, or left ventricular diameter. At follow up, aortic valve function was also comparable between groups, with a peak/mean gradient of 9.4 +/- 6.4/5.3 +/- 3.5 mmHg and 5.1 +/- 3.3/2.8 +/- 1.5 mmHg for groups D and Y, respectively (p = 0.081/0.058). The measured mean grades of aortic valve regurgitation were comparable in groups D and Y (0.6 +/- 0.7 and 1.1 +/- 0.6, respectively; p = 0.055). However, aortic root dimensions obtained via M-mode were smaller in group D patients (29.6 +/- 2.3 mm) than in group Y patients (36.1 +/- 6.6 mm) (p = 0.027). Only three patients from group Y required reoperation on the aortic valve due to valvular regurgitation (p = 0.028); two of these had presented with aortic dissection at the first operation. Both types of AVSP can be performed with comparably good interim clinical results, and also low mortality and morbidity, in patients with Marfan syndrome.

We describe a patient with severe hemophilia A and Marfan syndrome who underwent an elective Bentall operation. Because of the severe hemophilia, anticoagulation could not be given postoperatively; thus, a biologic Valsalva conduit graft was used. During the procedure, factor VIII was given as a bolus dose just before incision, then by continous infusion intraoperatively to maintain the factor VIII activity level between 200% and 300%. Minimal postoperative bleeding occurred. The infusion was continued postoperatively at a lower dose until all chest tubes, pacing wires, and invasive catheters were removed. The patient was discharged on postoperative day 7 without adverse events. Copyright © 2016 The Society of Thoracic Surgeons. Published by Elsevier Inc. All rights reserved.

One month previously, a 28-year old male underwent an emergency modified Bentall procedure because of Marfan syndrome with acute aortic dissection Stanford Class A. Computed tomography of the chest did not reveal severe graft stenosis of the anastomosis. To explore the cause of anaemia, renal dysfunction and macroscopic haematuria, the patient was tested for antineutrophil cytoplasmic antibody (ANCA)-associated systemic vasculitis (AASV). Antimyeloperoxidase antibodies (MPO)-ANCA and antiproteinase 3 antibodies (PR3)-ANCA were strongly positive. Corticosteroid therapy was applied, followed by cyclophosphamide and azathioprine. In response to treatment, the MPO-ANCA and PR3-ANCA levels gradually decreased, proteinuria was alleviated and haemoglobin levels returned to normal after 6 months. This is the first report to highlight haemolytic anaemia and AASV with Marfan syndrome after surgery for aortic dissection.

Marfan syndrome (MFS) is a genetic disease often marked by the presence of scoliosis. There is no three-dimensional analysis of the deformity in the literature. Our aim was to determine what kind of sagittal balance defines scoliosis associated with MFS, namely a flexion deformity, as it is in scoliosis associated with Chiari I or an extension deformity, as in adolescent idiopathic scoliosis (AIS). To address this issue, we compared the presence or absence of a thoracic scoliosis with the presence or absence of a segment in extension in the thoracic spine. In our series, 30 patients diagnosed with Marfan syndrome were prospectively included. In each patient, personalized three-dimensional reconstruction from T1 to L5 of the spine was made using stereoradiography. The patients were first separated based on the presence or absence of thoracic scoliosis, in order to compare this with the presence or absence of a segment in extension in the thoracic spine. They were then classified into two groups based on the presence or absence of the segment in extension (meaning containing negative values of inter-vertebral sagittal rotation) in the thoracic spine. Among scoliotic patients with a thoracic scoliosis (17 cases), there were 13 (76.5% cases) with a segment in extension in the thoracic spine and 4 with no segment in extension. Our results showed that scoliosis associated with MFS is somehow original, demonstrating a sagittal balance in extension (as AIS) in about 80% of thoracic curves, but without this characteristic feature in about 20%.

A Marfan syndrome-like phenotype caused by a neocentromeric supernumerary ring chromosome 15.

Quinonez, Shane C; Gelehrter, Thomas D; Uhlmann, Wendy R

Small supernumerary marker chromosomes (sSMC) are abnormal chromosomes that cannot be characterized by standard banding cytogenetic techniques. A minority of sSMC contain a neocentromere, which is an ectopic centromere lacking the characteristic alpha-satellite DNA. The phenotypic manifestations of sSMC and neocentromeric sSMC are variable and range from severe intellectual disability and multiple congenital anomalies to a normal phenotype. Here we report a patient with a diagnosis of Marfan syndrome and infertility found to have an abnormal karyotype consisting of a chromosome 15 deletion and a ring-type sSMC likely stabilized by a neocentromere derived via a mechanism initially described by Barbara McClintock in 1938. Analysis of the sSMC identified that it contained the deleted chromosome 15 material and also one copy of FBN1, the gene responsible for Marfan syndrome. We propose that the patient's diagnosis arose from disruption of the FBN1 allele on the sSMC. To date, a total of 29 patients have been reported with an sSMC derived from a chromosomal deletion. We review these cases with a specific focus on the resultant phenotypes and note significant difference between this class of sSMC and other types of sSMC. Through this review we also identified a patient with a clinical diagnosis of neurofibromatosis type 1 who lacked a family history of the condition but was found to have a chromosome 17-derived sSMC that likely contained NF1 and caused the patient's disorder. We also review the genetic counseling implications and recommendations for a patient or family harboring an sSMC. © 2016 Wiley Periodicals, Inc. © 2016 Wiley Periodicals, Inc.

Marfan syndrome (MFS) is associated with progressive aortic dilatation, endothelial dysfunction, and oxidative stress that contribute to the early acute dissection of the vessel and can end up in rupture of the aorta and sudden death. Many studies have described that the organic acids from Hibiscus sabdariffa Linne (HSL) calyces increase cellular antioxidant capacity and decrease oxidative stress. Here we evaluate if the antioxidant properties of HSL infusion improve oxidative stress in MFS patients. Activities of extra cellular super oxide dismutase (ECSOD), glutathione peroxidase (GPx), glutathione-S-transferase (GST), glutathione reductase (GSSG-R), glutathione (GSH), lipid peroxidation (LPO) index, total antioxidant capacity (TAC), and ascorbic acid were determined in plasma from MFS patients. Values before and after 3 months of the treatment with 2% HSL infusion were compared in control and MFS subjects. After treatment, there was a significant decrease in ECSOD (p = 0.03), EGPx (p = 0.04), GST (p = 0.03), GSH (p = 0.01), and TAC and ascorbic acid (p = 0.02) but GSSG-R activity (p = 0.04) and LPO (p = 0.02) were increased in MFS patients in comparison to patients receiving the HSL treatment and C subjects. Therefore, the infusion of HSL calyces has antioxidant properties that allow an increase in antioxidant capacity of both the enzymatic and nonenzymatic systems, in the plasma of the MSF patients.

Marfan syndrome (MFS) is associated with progressive aortic dilatation, endothelial dysfunction, and oxidative stress that contribute to the early acute dissection of the vessel and can end up in rupture of the aorta and sudden death. Many studies have described that the organic acids from Hibiscus sabdariffa Linne (HSL) calyces increase cellular antioxidant capacity and decrease oxidative stress. Here we evaluate if the antioxidant properties of HSL infusion improve oxidative stress in MFS patients. Activities of extra cellular super oxide dismutase (ECSOD), glutathione peroxidase (GPx), glutathione-S-transferase (GST), glutathione reductase (GSSG-R), glutathione (GSH), lipid peroxidation (LPO) index, total antioxidant capacity (TAC), and ascorbic acid were determined in plasma from MFS patients. Values before and after 3 months of the treatment with 2% HSL infusion were compared in control and MFS subjects. After treatment, there was a significant decrease in ECSOD (p = 0.03), EGPx (p = 0.04), GST (p = 0.03), GSH (p = 0.01), and TAC and ascorbic acid (p = 0.02) but GSSG-R activity (p = 0.04) and LPO (p = 0.02) were increased in MFS patients in comparison to patients receiving the HSL treatment and C subjects. Therefore, the infusion of HSL calyces has antioxidant properties that allow an increase in antioxidant capacity of both the enzymatic and nonenzymatic systems, in the plasma of the MSF patients.

Apart from typical Marfan syndrome (MS), several Marfan-like conditions are known. One of those is the MASS syndrome (Mitral involvement, Aortic dilatation, Skin and Skeletal abnormalities) defined by Pyeritz et al. Among these, a dominantly inherited mitral valve prolapse with marfanoid habitus have also been reported. Until now, except for a Marfan-like condition described by Boileau et al., all Marfan families are linked to fib 15. A large Belgian pedigree with 25 affected patients among 62 at risk subjects spanning four generations is described. A syndrome including marfanoid skeletal dysplasia (tall stature, dolichostenomelia, arachnodactyly, pectus carinatum joint dislocation), prolapse and/or myxomatous degeneration of the mitral valve, but without aortic dilatation of eye involvement was observed. Although the phenotype fulfills Berlin diagnostic criteria for MS, it closely resembles MASS syndrome. Preliminary linkage results show discordance aggregation insertion in the fib 15 gene, as evaluated by intragenic microsatellite fib 15. Since Dietz et al. described a similar patient with fib 15 gene, we suggest that this variant of Marfan syndrome is genetically heterogeneous and caused by mutations, some of which are allelic to classical Marfan syndrome plus a subtype, some of which are not. Linkage studies are under way to further characterize the gene involved in the present family.

Early morbidity and mortality in patients with Marfan syndrome (MFS) -a connective tissue disease caused by mutations in fibrillin-1 gene- are mainly caused by aorta aneurysm and rupture. However, the increase in the life expectancy of MFS patients recently achieved by reparatory surgery promotes clinical manifestations in other organs. Although some studies have reported respiratory alterations in MFS, our knowledge of how this connective tissue disease modifies lung mechanics is scarce. Hence, we assessed whether the stiffness of the whole lung and of its extracellular matrix (ECM) is affected in a well-characterized MFS mouse model (FBN1C1039G/+). The stiffness of the whole lung and of its ECM were measured by conventional mechanical ventilation and atomic force microscopy, respectively. We studied 5-week and 9-month old mice, whose ages are representative of early and late stages of the disease. At both ages, the lungs of MFS mice were significantly more compliant than in wild type (WT) mice. By contrast, no significant differences were found in local lung ECM stiffness. Moreover, histopathological lung evaluation showed a clear emphysematous-like pattern in MFS mice since alveolar space enlargement was significantly increased compared with WT mice. These data suggest that the mechanism explaining the increased lung compliance in MFS is not a direct consequence of reduced ECM stiffness, but an emphysema-like alteration in the 3D structural organization of the lung. Since lung alterations in MFS are almost fully manifested at an early age, it is suggested that respiratory monitoring could provide early biomarkers for diagnosis and/or follow-up of patients with the Marfan syndrome.

Full Text Available We present herein a 23-year-old man with acute myeloblastic leukemia (AML associated with Davidoff-Dyke-Masson syndrome (DDMS and Marfan syndrome (MS. The diagnosis of DDMS was based on findings including left facial asymmetry, left hemiparesis, mental retardation, right cerebral hemiatrophy, dilatation of the ipsilateral lateral ventricle and calvarial thickening. The diagnosis of MS was based on clinical findings including tall stature, myopia, retinitis pigmentosa, blue scleras, scoliosis, pectus excavatum, arachnodactyly and low ratio of upper/lower body segment. The patient developed hepatosplenomegaly, gingival hypertrophy and pancytopenia. Peripheral blood film and bone marrow examination showed that most of nucleated cells were blasts; immunophenotype of those cells showed CD11+, CD13+, CD14+, CD33+ and HLA-DR+. These findings confirmed the diagnosis of AML (FAB-M5. After induction chemotherapy, remission was obtained. To the best of our knowledge, our case is the third report of AML in MS syndrome, while AML associated with DDMS and MS has not been previously reported in the literature.

The percentage of employment in the Marfan patient after the Bentall procedure was studied. Eighteen of 20 patients (90%) returned to their daily life and are working well after the surgery. Seven patients (35%) needed the second operation due to the enlargement of false lumen during the follow-up period. Fatal cardiovascular accidents occurred in 7 their families (35%) in our series. Careful follow-up, adequate selection of medical and surgical treatment including second operation, medical examination of their families are important to keep the good quality of life in the Marfan patient.

Full Text Available Marfan syndrome (MFS is a variable, autosomal dominant disorder of connective tissue whose cardinal features affect the cardiovascular system, eyes, and skeleton. The patient′s prognosis depends on the severity of cardiovascular complications and is mainly determined by progressive dilation of the aorta. If signs of MFS are recognized, it is important to refer to the correct health care professional for further testing to prevent associated complications. Hereby, we report a case of MFS who was unaware about the cardiac manifestations, thereby emphasizing the importance in identifying this potentially life-threatening condition in dental practice.

Although the aortic-valve-sparing (AVS) reimplantation technique according to David has shown favorable durability results in mid-term and long-term studies, composite valve grafting (CVG) according to Bentall is still considered the standard procedure. Retrospectively, we evaluated the results of aortic root replacement of patients with Marfan syndrome (MFS) who underwent surgery between January 1995 and January 2010. MFS was diagnosed using the Ghent criteria. AVS was used in 58 patients and CVG in 30 patients with MFS. AVS was done for aortic-root aneurysm (n=48) or aortic dissection type A (n=10). CVG was used for aortic-root aneurysm in 14 patients or aortic dissection type A in 16 patients. The mean follow-up was 3.2 (95% CI: 2.4-4.2) years. In both groups, 30-day mortality was 0%. Three patients (10.0%) in the CVG group required resternotomy for postoperative bleeding versus two patients (3.4%) in the AVS group (p=0.3). At follow-up, mortality was 10% in the CVG group versus 3.4% in the AVS group (p=0.3). Re-operation was required in two patients (3.4%) after AVS and in three patients after CVG (10%) (p=0.3). Three patients (10.0%) who underwent CVG had endocarditis and two patients (6.7%) had a stroke during follow-up, whereas no endocarditis and stroke occurred after AVS. After 14 years, stratified event-free survival was better in the AVS group (event-free survival was 82.3% vs 58.6%, log-rank test p=0.086), especially after aneurysm (p=0.057). After 10 years, freedom from aortic regurgitation ≥II° in the AVS group was 80% for aneurysm and 50% after dissection (p=0.524). The reimplantation technique according to David was associated with excellent survival, good valve function and a low rate of re-operation, endocarditis, and stroke. There was a trend to better event-free survival for AVS patients making it the procedure of choice in MFS patients. Copyright © 2011 European Association for Cardio-Thoracic Surgery.

Marfan syndrome is characterized by high expression of matrix metalloproteinases (MMPs) in aortic smooth muscle cells (AoSMCs) associated with medial elastolysis and aortic root aneurysm. We aimed to reduce aortic elastolysis through decrease of MMP expression with decoy oligodeoxynucleotides (dODNs) neutralizing the transcription factor activating factor-1 (AP-1). AP-1 abundance in nuclear extracts as well as MMP-2 and MMP-9 expression were significantly increased in isolated mAoSMC of mgR/mgR Marfan mice compared to wild-type cells. Exposure to AP-1 neutralizing dODNs resulted in a significant reduction of basal and interleukin-1β-stimulated MMP expression and activity in mAoSMCs. Moreover, increased migration and formation of superoxide radical anions was substantially decreased in mAoSMCs by AP-1 dODN treatment. Aortic grafts from donor Marfan mice were treated with AP-1- dODN ex vivo and implanted as infrarenal aortic interposition grafts in mgR/mgR mice. Pretreatment of aortic grafts with AP-1 dODN led to reduced elastolysis, macrophage infiltration, and MMP activity. Permeability of the endothelial monolayer was increased for dODN in mgR/mgR aortae with observed loss of tight junction proteins ZO-1 and occludin, enabling dODN to reach the tunica media. Targeting AP-1 activity offers a new potential strategy to treat the vascular phenotype associated with Marfan syndrome. Copyright © 2017 The Author(s). Published by Elsevier Inc.

In Marfan syndrome, aneurysmatic enlargement of ascending aorta and dissection starting at the root are the most common cardiovascular complications. We present an infrequent case of a 15-year-old patient with a typical case of Marfan syndrome. CT disclosed an aorta and aortic arch of normal size with dissection originating distally with respect to the point where left subclavian artery arises. The disecction extended to descending aorta and to iliac and femoral arteries. Aortic rupture occurred in the arch, with massive hemothorax. The CT findings were confirmed at necropsy. 9 refs.

Loeys-Dietz syndrome (LDS) is a connective tissue disease caused by mutations in the genes encoding the transforming growth factor-β receptor (TGFBR). LDS is associated with aneurysms or dissections of the aorta similar to Marfan syndrome (MFS) as well as arterial tortuosity and aneurysms in the peripheral arteries. The purpose of this study was to evaluate the arterial diseases of LDS to differentiate it from MFS. A total of 10 LDS patients with an identified mutation in TGFBR (6 male, 4 female; mean age 36.3 years) and 20 MFS patients with an identified mutation in fibrilin-1 who were age- and sex-matched to the LDS subjects (12 male, 8 female; mean age 37.1 years) were reviewed. The prevalence of vertebral arterial tortuosity (VAT) and peripheral aneurysm (PAN) was studied using computed tomography angiography. In all, 9 of the 10 LDS patients had VAT, and five PANs were observed in 3 patients. In contrast, 8 (40%) of the MFS patients had VAT, and 1 patient had a PAN. LDS had a higher prevalence of VAT (P=0.017) by Fisher's exact test. The VAT was highly prevalent among LDS patients. Thus, the presence of VAT has the potential to differentiate LDS from MFS.

This report describes the hybrid endovascular treatment of an aortic root dilatation and a thoracoabdominal aneurysm in a high-risk patient with Marfan syndrome. A 50-year-old male, in hemodialysis for polycystic kidney and polycystic liver, was referred to our department for aortic root dilatation of 5 cm and a 6.3-cm thoracoabdominal aneurysm . He already underwent surgical repair of abdominal aortic aneurysm 10 years ago, complicated by pseudoaneurysm of the proximal anastomosis that had been treated in another center, with an endoprosthesis. The patient underwent aortic root replacement, aortic valve sparing operation, and rerouting of the superior mesenteric artery and celiac trunk to the ascending aorta. The thoracoabdominal aneurysm was excluded with an endoprosthesis few days after the surgical step. The 12-month computed tomography scan confirmed the complete exclusion of the thoracoabdominal aneurysm.

Possible extracardiac predictors of aortic dissection in Marfan syndrome

Science.gov (United States)

2014-01-01

Background According to previous studies, aortic diameter alone seems to be insufficient to predict the event of aortic dissection in Marfan syndrome (MFS). Determining the optimal schedule for preventive aortic root replacement (ARR) aortic growth rate is of importance, as well as family history, however, none of them appear to be decisive. Thus, the aim of this study was to search for potential predictors of aortic dissection in MFS. Methods A Marfan Biobank consisting of 79 MFS patients was established. Thirty-nine MFS patients who underwent ARR were assigned into three groups based on the indication for surgery (dissection, annuloaortic ectasia and prophylactic surgery). The prophylactic surgery group was excluded from the study. Transforming growth factor-β (TGF-β) serum levels were measured by ELISA, relative expression of c-Fos, matrix metalloproteinase 3 and 9 (MMP-3 and −9) were assessed by RT-PCR. Clinical parameters, including anthropometric variables - based on the original Ghent criteria were also analyzed. Results Among patients with aortic dissection, TGF-β serum level was elevated (43.78 ± 6.51 vs. 31.64 ± 4.99 ng/l, p < 0.0001), MMP-3 was up-regulated (Ln2α = 1.87, p = 0.062) and striae atrophicae were more common (92% vs. 41% p = 0.027) compared to the annuloaortic ectasia group. Conclusions We found three easily measurable parameters (striae atrophicae, TGF-β serum level, MMP-3) that may help to predict the risk of aortic dissection in MFS. Based on these findings a new classification of MFS, that is benign or malignant is also proposed, which could be taken into consideration in determining the timing of prophylactic ARR.

The authors examined the state of patients suffering from Marfan syndrome (MS) who endured operation for ascending aorta aneurysm with replacement of the ascending aorta and aortic valve (Bentall operation), studying alterations of the skeleton, face, heart and eyes, as well as pathomorphological restructurings in the aortic wall. The study was carried out 7.0 ± 4.2 years after the operation. We examined a total of 39 patients with MS - 27 (69.2%) men and 12 (30.8%) women aged from 22 to 70 years old (average age - 42.1 ± 13.4 years). All patients were operated on for dissecting aneurysm of the ascending aorta accompanied by a considerable degree of aortic valve insufficiency or aortic ostium stenosis. The mean diameter of the aorta at the level of the sinuses of Valsalva amounted to 7.0 ± 1.3 cm (minimal - 5.0 cm, maximal - 12.0 cm), the Z-score prior to operation was 12.7 ± 6.5. The time form making the diagnosis of MS to surgical intervention for aortic aneurysm amounted to 9.6 ± 5.9 years. The condition after operative treatment in all patients was satisfactory, with the haemodynamic indices stable: systolic AP - 133.5 ± 19.1 mm Hg, diastolic AP 85.1 ± 12.9 mm Hg, heart rate 74.8 ± 7.2 bpm. The average systemic score for the symptoms and tests of MS patients amounted to 8.2 ± 3.3 points. Pathohistological alterations of the aorta in patients with Marfan syndrome consisted in pronounced restructuring of the wall with deep irreversible alternative changes. The pathological process extended in the middle aortic layer all alone the length, but not only in the portions of rupture and dissection. The main pathomorphological signs in MS were as follows: focal accumulations of mucoid substances, dystrophic alterations of smooth-muscle cells, ribbon-like anuclear zones, formation of cystlike cavities, alterations of elastic fibres - fragmentation, hyperelastosis, multiplication, thinning and straightening, zones of elastolysis.

Marfan syndrome (MFS) is characterized by the formation of ascending aortic aneurysms resulting from altered assembly of extracellular matrix fibrillin-containing microfibrils and dysfunction of TGF-β signaling. Here we identify the molecular targets of redox stress in aortic aneurysms from MFS patients, and investigate the role of NOX4, whose expression is strongly induced by TGF-β, in aneurysm formation and progression in a murine model of MFS. Working models included aortae and cultured vascular smooth muscle cells (VSMC) from MFS patients, and a NOX4-deficient Marfan mouse model (Fbn1 C1039G/+ -Nox4 -/- ). Increased tyrosine nitration and reactive oxygen species levels were found in the tunica media of human aortic aneurysms and in cultured VSMC. Proteomic analysis identified nitrated and carbonylated proteins, which included smooth muscle α-actin (αSMA) and annexin A2. NOX4 immunostaining increased in the tunica media of human Marfan aorta and was transcriptionally overexpressed in VSMC. Fbn1 C1039G/+ -Nox4 -/- mice aortas showed a reduction of fragmented elastic fibers, which was accompanied by an amelioration in the Marfan-associated enlargement of the aortic root. Increase in the contractile phenotype marker calponin in the tunica media of MFS mice aortas was abrogated in Fbn1 C1039G/+ -Nox4 -/- mice. Endothelial dysfunction evaluated by myography in the Marfan ascending aorta was prevented by the absence of Nox4 or catalase-induced H 2 O 2 decomposition. We conclude that redox stress occurs in MFS, whose targets are actin-based cytoskeleton members and regulators of extracellular matrix homeostasis. Likewise, NOX4 have an impact in the progression of the aortic dilation in MFS and in the structural organization of the aortic tunica media, the VSMC phenotypic modulation, and endothelial function.

Several recent studies have compared the clinical results of valve-sparing (VS) surgery and composite valve graft (CVG) surgery in the aortic root reconstruction of Marfan syndrome (MS) patients. The study aim was to investigate whether it is appropriate to preserve the native aortic valve in root surgery of MFS patients when taking the short-term and long-term prognoses into consideration. A thorough literature search of PubMed, Embase and Cochrane library was conducted to identify studies comparing the outcomes of VS and CVG surgery in MFS patients. The Newcastle-Ottawa Scale evaluation scheme was used to assess the methodological quality of the included articles. Data were extracted from reports and analyzed using Revman 5.0, supplied by Cochrane collaboration. Six clinical trials incorporating 539 patients were included. Compared to CVG, VS surgery was associated with a lower risk for re-exploration (RR 0.48, 95% CI 0.24-0.97; p = 0.04), thromboembolic events (RR 0.17, 95% CI 0.05-0.57; p = 0.004) and endocarditis (RR 0.31, 95% CI 0.11-0.94; p = 0.04). Despite an inherent incidence of aortic regurgitation, VS surgery resulted in an elevation of long-term survival rate; however, no statistical differences were found between groups with regards to reoperation (RR 1.07, 95% CI 0.35-3.27; p = 0.91). Root reconstruction with VS surgery can effectively improve the prognosis of MFS patients and provide a promising alternative for surgical treatment. However, the results must be interpreted with caution due to the retrospective nature of the included studies; large-scale prospective control trials are needed to confirm these findings.

Personalized external aortic root support (PEARS) is a novel surgical approach with the aim of stabilizing the aortic root size and decreasing risk of dissection in Marfan syndrome patients. A bespoke polymer mesh tailored to each patient's individual aorta shape is produced by modeling and then surgically implanted. The aim of this study is to assess the mechanical effects of PEARS on the aortic root systolic downward motion (an important determinant of aortic wall stress), aortic root distension and on the left ventricle (LV). A cohort of 27 Marfan patients had a prophylactic PEARS surgery between 2004 and 2012 with 24 having preoperative and follow-up cardiovascular magnetic resonance imaging studies. Systolic downward aortic root motion, aortic root distension, LV volumes/mass and mitral annular systolic excursion before the operation and in the latest follow-up were measured randomly and blinded. After a median follow-up of 50.5 (IQR 25.5-72) months following implantation of PEARS, systolic downward motion of aortic root was significantly decreased (12.6±3.6mm pre-operation vs 7.9±2.9mm latest follow-up, p<0.00001). There was a tendency for a decrease in systolic aortic root distension but this was not significant (median 4.5% vs 2%, p=0.35). There was no significant change in LV volumes, ejection fraction, mass and mitral annular systolic excursion in follow-up. PEARS surgery decreases systolic downward aortic root motion which is an important determinant of longitudinal aortic wall stress. Aortic wall distension and Windkessel function are not significantly impaired in the follow-up after implantation of the mesh which is also supported by the lack of deterioration of LV volumes or mass.
