    The structure and functioning of the atrioventricular (AV) node has remained mysterious owing to its high degree of complexity. In this review article, we integrate advances in knowledge regarding connexin expression in the AV node. Complex patterning of 4 different connexin isoforms with single channel conductances ranging from ultralow to high explains the dual pathway electrophysiology of the AV node, the presence of 2 nodal extensions, longitudinal dissociation in the penetrating bundle, ...

    The electrical impulse for cardiac contraction is generated in the Sinoatrial node (SA node), subsequently spreads to the Atrioventricular node (AV node) and continues in the Atrioventricular bundle (AV bundle). The AV node may not always be present in different avian species and seems to differ in location and contents between species. In this study, the anatomy and histology of the AV node were studied five female adult ostriches (Struthio camelus). Routine paraffin sectioning and transmission electron microscopic method were performed. The study showed that in the ostrich, the AV node is located in the endocardium of the atrial surface of the right atrioventricular valve adjacent to the fibrous ring. The parenchyma of the AV node is formed by small specialized muscle fibres that are spread within a loose connective tissue network. The AV node is not covered by a connective tissue sheath and some arterioles are present. Nerve fibres are seen related to the node. Ultrastructurally, they stain lighter and contain fewer organized myofibrils than usual myocardial cells. The myofibril bundles run parallel to one another and have interspersed mitochondria, which display distinct cristae. The cells have a large euchromatic nucleus with a clear perinuclear area, and they connected by desmosomes. The ostrich is, thus, one of the birds that have the AV node, whose position varies from the other birds. PMID:21943125

    The presence of distinct electrophysiological pathways within the atrioventricular node (AVN) is a prerequisite for atrioventricular nodal reentrant tachycardia to occur. In this study, the different cell contributions that may account for the anatomical and functional heterogeneity of the AVN were investigated. To study the temporal development of the AVN, the expression pattern of ISL1, expressed in cardiac progenitor cells, was studied in sequential stages performing co-staining with myocardial markers (TNNI2 and NKX2-5) and HCN4 (cardiac conduction system marker). An ISL1+/TNNI2+/HCN4+ continuity between the myocardium of the sinus venosus and atrioventricular canal was identified in the region of the putative AVN, which showed a pacemaker-like phenotype based on single cell patch-clamp experiments. Furthermore, qPCR analysis showed that even during early development, different cell populations can be identified in the region of the putative AVN. Fate mapping was performed by in ovo vital dye microinjection. Embryos were harvested and analysed 24 and 48 hrs post-injection. These experiments showed incorporation of sinus venosus myocardium in the posterior region of the atrioventricular canal. The myocardium of the sinus venosus contributes to the atrioventricular canal. It is postulated that the myocardium of the sinus venosus contributes to nodal extensions or transitional cells of the AVN since these cells are located in the posterior region of the AVN. This finding may help to understand the origin of atrioventricular nodal reentrant tachycardia. PMID:25752780

    Full Text Available In this clinical observation is shown the data of the patient who was previously undergone paranodal ablation of atrial-ventricular junction for the treatment of atrioventricular (AV nodal reentrant tachycardia. Radiofrequency ablation of right lower isthmus for treatment of the paroxysmal form of atrial flutter was made for the patient. Sick sinus node syndrome and paroxysmal form of atrial fibrillation were diagnosed. Then dual-chamber pacemaker was implanted. Antiarrhythmic therapy about the persistent form of atrial fibrillation had no effect. The decision for the implementation of radio frequency modification of atrioventricular connection using right ventriclar access failed because of the lack of verification of the His bundle's spike. Using retrograde access through the aorta we managed to create AV blockade of III degree. Taking into account the fact that in 1990-ies patients with atrioventricular nodal reentrant tachycardia were operated using paranodal ablation of the AV node using extracorporeal circulation, this case has a practical significance when endovascular catheter modification of AV nodal conduction in this category of patients is made.

  5. An improved in vivo method for atrioventricular node ablation via thoracotomy

    Full Text Available The atrioventricular (AV node is permanently damaged in approximately 3% of congenital heart surgery operations, requiring implantation of a permanent pacemaker. Improvements in pacemaker design and in alternative treatment modalities require an effective in vivo model of complete heart block (CHB before testing can be performed in humans. Such a model should enable accurate, reliable, and detectable induction of the surgical pathology. Through our laboratory’s efforts in developing a tissue engineering therapy for CHB, we describe here an improved in vivo model for inducing chronic AV block. The method employs a right thoracotomy in the adult rabbit, from which the right atrial appendage may be retracted to expose an access channel for the AV node. A novel injection device was designed, which both physically restricts needle depth and provides electrical information via electrocardiogram interface. This combination of features provides real-time guidance to the researcher for confirming contact with the AV node, and documents its ablation upon formalin injection. While all animals tested could be induced to acute AV block, those with ECG guidance were more likely to maintain chronic heart block >12 h. Our model enables the researcher to reproduce both CHB and the associated peripheral fibrosis that would be present in an open congenital heart surgery, and which would inevitably impact the design and utility of a tissue engineered AV node replacement.

    Full Text Available Objective: This study is to evaluate the feasibility and safety of intracardiac radiofrequency catheter ablation (RFCA of the atrioventricular node (AVN and pacemaker implantation using transthoracic echocardiography. Methods: Eleven patients – six males and five females (mean age 66 years – with persistent or permanent atrial fibrillation/atrial flutter received RFCA of AVN and VVI pacemaker implantation (paces and senses the ventricle and is inhibited if it senses ventricular activity. Under transthoracic echocardiography, the electrode catheters were positioned intracardiac, and target ablation was performed, with the permanent pacemaking catheter in the left subclavian vein and the ablation catheter in the right femoral vein. The multi-view imaging and dynamic observation applied during the stable AV dissociation were successful. Results: Atrioventricular node ablation and permanent pacemaker implantation in 11 patients were completed successfully without X-ray exposure. The operation success rate was 100%. All patients recovered well within the follow-up period. Conclusions: Radiofrequency catheter ablation of AVN and VVI pacemaker implantation under transthoracic echocardiography guidance is a safe, easy and feasible approach. This procedure could be an important supplemental measure to catheter ablation of arrhythmia under routine X-ray fluoroscopy.

    Ablation of persistent atrial fibrillation is still a challenge for the ablationist. Extensive ablation is required under some conditions and could lead to some unintended complications. Here we report a case of atrium-atrioventricular node block complicating multiple catheter ablation procedures for persistent atrial fibrillation. After extensive ablation, including circumferential pulmonary vein ablation, linear ablation at the left atrial roof, mitral isthmus, atrial septum, cavotricuspid isthmus, and complex fractionated atrial electrogram ablation, conduction obstacle was found, and sinus impulse could not travel from the right atrium, atrial septum and left atrium to atrioventricular node. The case indicated that intensive ablation at some key sites, especially the interatrial septum, should be careful during ablation of atrial fibrillation.

    Atrioventricular node (AVN) ablation is an effective treatment for symptomatic patients with atrial arrhythmias who are refractory to rhythm and rate control strategies where optimal ventricular rate control is desired. There are limited data on the predictors of failure of AVN ablation. Our objective was to identify the predictors of failure of AVN ablation. This is an observational single-center study of consecutive patients who underwent AVN ablation in a large academic center. Baseline characteristics, procedural variables, and outcomes of AVN ablation were collected. AVN "ablation failure" was defined as resumption of AVN conduction resulting in recurrence of either rapid ventricular response or suboptimal biventricular pacing. A total of 247 patients drug refractory AF who underwent AVN ablation at our center with a mean age of 71 ± 12 years with 46% being males were included. Ablation failure was seen in 11 (4.5%) patients. There were no statistical differences between patients with "ablation failure" versus "ablation success" in any of the baseline clinical variables. Patients with moderate-to-severe tricuspid regurgitation (TR) were much more likely to have ablation failure than those with ablation success (8 [73%] vs 65 [27%]; p = 0.003). All 11 patients with ablation failure had a successful redo procedure, 9 with right and 2 with the left sided approach. On multivariate analysis, presence of moderate-to-severe TR was found to be the only predictor of failure of AVN ablation (odds ratio 9.1, confidence interval 1.99 to 42.22, p = 0.004). In conclusion, moderate-to-severe TR is a strong and independent predictor of failure of AVN ablation. PMID:26174606

    The atrioventricular node (AVN) of the cardiac conduction system coordinates atrial-ventricular excitation and can act as a subsidiary pacemaker. Recent evidence suggests that an inward background sodium current, IB,Na, carried by nonselective cation channels (NSCCs), contributes to AVN cell pacemaking. The study of the physiological contribution of IB,Na has been hampered, however, by a lack of selective pharmacological antagonists. This study investigated effects of the NSCC inhibitor SKF-96365 on spontaneous activity, IB,Na, and other ionic currents in AVN cells isolated from the rabbit. Whole-cell patch-clamp recordings of action potentials (APs) and ionic currents were made at 35-37°C. A concentration of 10 μmol/L SKF-96365 slowed spontaneous action potential rate by 13.9 ± 5.3% (n = 8) and slope of the diastolic depolarization from 158.1 ± 30.5 to 86.8 ± 30.5 mV sec(-1) (P < 0.01; n = 8). Action potential upstroke velocity and maximum diastolic potential were also reduced. Under IB,Na-selective conditions, 10 μmol/L SKF-96365 inhibited IB,Na at -50 mV by 36.1 ± 6.8% (n = 8); however, effects on additional channel currents were also observed. Thus, the peak l-type calcium current (ICa,L) at +10 mV was inhibited by 38.6 ± 8.1% (n = 8), while the rapid delayed rectifier current, IKr, tails at -40 mV following depolarization to +20 mV were inhibited by 55.6 ± 4.6% (n = 8). The hyperpolarization-activated current, If, was unaffected by SKF-96365. Collectively, these results indicate that SKF-96365 exerts a moderate inhibitory effect on IB,Na and slows AVN cell pacemaking. However, additional effects of the compound on ICa,L and IKr confound the use of SKF-96365 to dissect out selectively the physiological role of IB,Na in the AVN. PMID:27288059

    A 55-year-old man was admitted to the intensive care unit on account of repeatedly occurring syncopes which developed at the peak of physical exertion. The attack was reproduced by exercise on a bicycle ergometer: the patient developed paroxysmal tachycardia with a narrow QRS and a frequency of 160/min leading after 20 sec. to severe hypotension and loss of consciousness. The same tachycardia caused by programmed atrial stimulation caused a drop of tension in the recumbent position by 30 mmHg and after more detailed analysis during electrophysiological examination it was evaluated as atrioventricular nodal reentrant tachycardia. By an electric discharge of 300 J administered by means of a stimulation electrode 7F USCI into the area of the AV node the retrograde conduction through the perinodal rapid pathways was completely interrupted and 1st. degree atrioventricular block developed. Repeated electrophysiological examination and exercise tests on a bicycle ergometer provided evidence of the disappearance of the retrograde pathway and the impossibility to elicit AVNRT. The authors express the view that the rapid perinodal pathway is interrupted in successful cases in both directions and the 1st. degree AV block is due to conduction along a slow pathway and not incidental slowing of conduction along the rapid pathway which is the generally accepted interpretation. Modification of the atrioventricular conduction by interruption of the rapid pathway by fulguration is according to data in the literature and the described patient a method which makes is possible to cure severe atrioventricular nodal reentrant tachycardias.

    The atrioventricular node (AVN) is a key component of the cardiac pacemaker-conduction system. This study investigated the electrophysiology of cells isolated from the AVN region of adult mouse hearts, and compared murine ionic current magnitude with that of cells from the more extensively studied rabbit AVN. Whole-cell patch-clamp recordings of ionic currents, and perforated-patch recordings of action potentials (APs), were made at 35–37°C. Hyperpolarizing voltage commands from −40 mV elicited a Ba2+-sensitive inward rectifier current that was small at diastolic potentials. Some cells (Type 1; 33.4 ± 2.2 pF; n = 19) lacked the pacemaker current, If, whilst others (Type 2; 34.2 ± 1.5 pF; n = 21) exhibited a clear If, which was larger than in rabbit AVN cells. On depolarization from −40 mV L-type Ca2+ current, ICa,L, was elicited with a half maximal activation voltage (V0.5) of −7.6 ± 1.2 mV (n = 24). ICa,L density was smaller than in rabbit AVN cells. Rapid delayed rectifier (IKr) tail currents sensitive to E-4031 (5 μmol/L) were observed on repolarization to −40 mV, with an activation V0.5 of −10.7 ± 4.7 mV (n = 8). The IKr magnitude was similar in mouse and rabbit AVN. Under Na-Ca exchange selective conditions, mouse AVN cells exhibited 5 mmol/L Ni-sensitive exchange current that was inwardly directed negative to the holding potential (−40 mV). Spontaneous APs (5.2 ± 0.5 sec−1; n = 6) exhibited an upstroke velocity of 37.7 ± 16.2 V/s and ceased following inhibition of sarcoplasmic reticulum Ca2+ release by 1 μmol/L ryanodine, implicating intracellular Ca2+ cycling in murine AVN cell electrogenesis.

    The atrioventricular (AV) node plays a fundamental role in patients with atrial fibrillation (AF), acting as a filter to the numerous irregular atrial impulses which bombard the node. A phenomenological approach to better understand AV nodal electrophysiology is to analyze the ventricular response with respect to irregularity. In different cohorts of AF patients, such analysis has been performed with the aim to evaluate the association between ventricular response characteristics and long-term clinical outcome and to determine whether irregularity is affected by rate-control drugs. Another approach to studying AV nodal characteristics is to employ a mathematical model which accounts for the refractory periods of the two AV nodal pathways. With atrial fibrillatory rate and RR intervals as input, the model has been considered for analyzing data during (i) rest and head-up tilt test, (ii) tecadenoson and esmolol, and (iii) rate-control drugs. The present paper provides an overview of our recent work on the characterization and assessment of AV nodal conduction using these two approaches. PMID:26324177

    Full Text Available Cardiac resynchronization therapy (CRT has evolved as an effective therapy for patients with congestive heart failure (CHF and ventricular dyssynchrony, currently defined as a wide QRS on the electrocardiogram. While multiple randomized controlled trials have confirmed the favorable effects of CRT on mortality and heart failure symptoms for patients in sinus rhythm, only recently observational studies have begun to suggest a similar benefit for patients with atrial fibrillation (AF and dyssynchrony. Yet, implementing effective biventricular pacing in patients with AF can be problematic due to competing intrinsic AV conduction. For patients with depressed ejection fractions needing AV node (AVN ablation to control fast ventricular rates, biventricular pacing has been shown to be superior to right ventricular pacing alone. When consistent pacing (over 90% of the time cannot be achieved in AF patients due to a rapid ventricular response despite pharmacological therapy, AVN ablation should be considered. The additional benefit of performing AVN ablation to promote biventricular pacing in patients without rapid ventricular rates remains uncertain. A randomized controlled trial is needed to test the incremental benefit of AVN ablation to promote biventricular pacing in heart failure patients with AF and wide QRS.

    Background Advances in catheter ablation procedures for the treatment of supraventricular arrhythmias have created the need to understand better the morphological and lectrophysiological characteristics of the inferior nodal extension (INE) and transitional cellular band (TCB) in the atrioventricular (AV) junctional area.Methods Firstly, we observed the histological features of 10 rabbit AV junctional areas by serial sections under light microscopy. Then we recorded the action potentials (Aps) of transitional cells (TCs) in the INE, TCBs, AV node, and ordinary right atrial myocytes from the AV junctional area of 30 rabbits using standard intracellular microeletrode techniques.Results Under light microscopy, the INE appeared to be mostly composed of transitional cells linking upward to the AV node. Four smaller TCBs originated in the orifice of the coronary sinus, the region between the septal leaflet of the tricuspid valve and the coronary sinus, the inferior wall of the left atrium, and the superior interatrial septum, respectively, all linking to the INE or the AV node.Compared with ordinary atrial myocytes, the AP of the TCs in both the INE and the TCBs had a spontaneous phase 4 depolarization (not present in ordinary atrial myocytes), with a less negative maximum diastolic potential, a smaller amplitude, a slower maximum velocity of AP upstroke, and a longer action potential duration at 50% repolarization (APD50) and at 30% repolarization (APD30).The AP characteristics of these TCs were similar to those of the AV node, except that the velocities of the phase 4 spontaneous depolarization were slower and their action potential durations at 90%repolarization (APD90) were shorter. Moreover, APD50 and APDa0 of the TCs of the TCBs were shorter than in the case of TCs of the AV node.Conclusions The TCs of the INE and TCBs are similar to slow response automatic cells. They provide a substrate for slow pathway conduction. In addition, repolarization heterogeneity

    Long-term survival rate of patients operated for partial atrioventricular (AV) canal is lower than that of the general population, and late complications are relatively significant: between 10 and 30% of operated patients present with left AV valve regurgitation, and up to 25% have to be reoperated for valve repair or replacement, left ventricular outflow tract obstruction or residual atrial septal defect. Because the left AV valve regurgitation is the most common complication following surgery, technical details in the surgical management of the mitral valve are the most important aspects of this procedure; for example, the decision to close the cleft and to perform an annuloplasty. The presence of mitral valve anomalies in 7-28% of the cases complicates further the surgical management of these valves. This article will describe in detail the operative technique of partial AV canal repair, and review the relevant literature. PMID:26685152

    circuito de reentrada; a função do nó AV, o intervalo PR e a freqüência de Wenckeback não se alteram no pós-operatório.Twenty patients (aged 20 to 71 years, thirteen of them females, presented recurrent and refractory nodal reentry tachycardia (NRT and were submitted to surgical treatment. The preoperative electrophysiological studies demonstrated classical NRT. All the patients had ventricular-atrial interval of less than 40 milliseconds, and the atrial retrograde depolarization started in the anterior portion of the A-V node. Additionaly, the patients presented retrograde atrial capture phenomenon, suggesting participation of atrio-nodal or atrio-Hisian anomalous pathways. The intraoperative mapping performed during ventricular pacing demonstrate retrograde atrial depolarization starting at the posterior area of the A-V node. The surgical procedure consisted in dissection of the posterior portion of the A-V node with a similar technique used in ablation of postero-septal anomalous pathways, taking care to preserve the Todaro tendon. No intra-nor-postoperative complications were observed. The programmed stimulation performed around the 15th postoperative day was unable to induce NRT. Five to 36 months after the procedure, the patients are asymptomatic with normal A-V conduction and without use of antiarrhythmic drugs. Notwithstanding the small number of cases and the ralatively short follow-up, the surgical procedure appears efficient to control NRT, while preserving intact A-V conduction.

  7. Myocardial bridging as a cause of paroxysmal atrioventricular block

    International Nuclear Information System (INIS)

    Paroxysmal atrioventricular (AV) block was induced by exercise in an otherwise healthy young man. The only abnormalities demonstrated at comprehensive cardiac evaluation were: 1) angiographic systolic narrowing of the left anterior descending coronary artery, and 2) reversible radionuclide hypoperfusion of the septum during exercise. It is postulated that ischemia of the conduction system due to systolic milking of the left anterior descending coronary artery was responsible for the paroxysmal AV block in this patient

    Full Text Available Cardiac sarcoidosis is a major cause of death in patients with systemic sarcoidosis. Cardiac manifestations are seen in 2.3% of the patients. Atrioventricular (AV block is one of the common manifestations of cardiac sarcoidosis. Other presentations of cardiac involvement include congestive heart failure, ventricular arrhythmias, and sudden cardiac death. The presence of AV block in young patients should raise the suspicion of sarcoidosis. AV block may be the only manifestation and patients may not have clinical evidence of pulmonary involvement. Here we describe a young male presented with exercise induced AV block rapidly progressing to complete heart block with recurrent syncope needing urgent pacemaker implantation. Factors that suggested an infiltrative process included his young age, rapidly progressive conduction abnormalities in the ECG in the absence of coronary disease, and previous history of cutaneous sarcoidosis.

    BACKGROUND Infective endocarditis (IE) involving the mitral valve can but rarely lead to complete atrioventricular block (CAVB). CASE REPORT A 74-year-old man with a history of infective endocarditis caused by Streptococcus gordonii (S. gordonii) presented to our emergency room with fever and loss of appetite, which had lasted for 5 days. On admission, results of serologic tests pointed to severe infection. Electrocardiography showed normal sinus rhythm with first-degree atrioventricular block and incomplete right bundle branch block, and transthoracic echocardiography and transesophageal echocardiography revealed severe mitral regurgitation caused by posterior leaflet perforation and 2 vegetations (5 mm and 6 mm) on the tricuspid valve. The patient was initially treated with ceftriaxone and gentamycin because blood and cutaneous ulcer cultures yielded S. agalactiae. On hospital day 2, however, sudden CAVB requiring transvenous pacing occurred, and the patient's heart failure and infection worsened. Although an emergent surgery is strongly recommended, even in patients with uncontrolled heart failure or infection, surgery was not performed because of the Child-Pugh class B liver cirrhosis. Despite intensive therapy, the patient's condition further deteriorated, and he died on hospital day 16. On postmortem examination, a 2×1-cm vegetation was seen on the perforated posterior mitral leaflet, and the infection had extended to the interventricular septum. Histologic examination revealed extensive necrosis of the AV node. CONCLUSIONS This rare case of CAVB resulting from S. agalactiae IE points to the fact that in monitoring patients with IE involving the mitral valve, clinicians should be aware of the potential for perivalvular extension of the infection, which can lead to fatal heart block.

  11. Association of temporary complete AV block and junctional ectopic tachycardia after surgery for congenital heart disease

    International Nuclear Information System (INIS)

    Junctional ectopic tachycardia (JET) is a postoperative complication with a mortality rate of up to 14% after surgery for congenital heart disease. This study evaluated the risk factors of JET and explored the association of postoperative temporary third degree atrioventricular (AV) block and the occurrence of JET. Data were collected retrospectively from 1158 patients who underwent surgery for congenital heart disease. The overall incidence of JET was 2.8%. Temporary third degree AV block occurred in 1.6% of cases. Permanent third degree AV block requiring pacemaker implantation occurred in 1% of cases. In all, 56% of patients with JET had temporary AV block (P < 0.001), whereas no case of postoperative JET was reported in patients with permanent AV block (P = 0.56). temporary third degree AV block did not suffer from JET. A correlation between temporary third degree AV block and postoperative JET could be observed. The risk factors identified for JET include younger age groups at the time of surgery, longer aortic cross clamping time and surgical procedures in proximity to the AV node

    the arterial dominance. RESULTS: The SA (sinoatrial node was supplied by the right coronary artery (RCA in 53% of the cases, by the circumflex (Cx branch of left coronary artery (LCA in 42.66%, and by both coronary arteries in 4.33% of cases. The AV (atrioventricular node was also more often supplied by the RCA (72.33% of cases than by the Cx branch of the LCA (27.66%, and surprisingly in none of the cases was this node supplied by both coronary arteries. CONCLUSION: The results of the present study may help cardiac surgeons, particularly in surgeries related to certain valvular disorders, due to the proximity of the nodal branches to the valve complex.

    Full Text Available Rheumatic heart disease remains the most important cause of acquired heart disease in children and young adults. Different kinds of rhythm and conduction disturbances may be seen during the course of acute rheumatic fever (ARF. Long PR intervals are found commonly in rheumatic fever, but complete atrioventricular (AV block is an exceptionally rare manifestation. This case report is about a 14 year-old-female patient diagnosed as ARF based on migratory arthralgia and mild carditis who also developed complete heart block on admission. Electrocardiogram on the 3rd day of hospitalization depicts 2nd degree atrioventricular block (Mobitz I combined with PR prolongation. The ECG revealed a normal sinus rhythm with PR prolongation on the 4th day of hospitalization. Rarely, complete AV heart block can occur as a complication of ARF and may develop during the acute phase

  16. Evolution and scaling of atrioventricular conduction time in mammals: part 2.

    Meijler, Frits L; Strackee, Jan

    2006-01-01

    This review in The American Heart Hospital Journal is published in two parts. Part 1 deals with the role of scaling in (patho)physiology and anatomy, or the function and structure of organs and organ systems in relation to body size of mammalian species. An intriguing aspect of scaling is the relation between heart size and the duration of atrioventricular (AV) conduction (Winter 2006 issue-Am Heart Hosp J. 2006;4:53-57.). Part 2 offers a simple mathematic explanation of AV conduction time scaling based on AV hemodynamics in mammalian species of different sizes. Changes of the PR interval (atrioventricular delay) in relation to changes of heart size in mammalian species (scaling) confront us with a perplexing lack of understanding of an essential function of the heart. The PR interval controls the duration of late diastolic blood flow from the atria to the ventricles. There is good evidence that blood flow velocity is fairly constant in all mammalian species, meaning it does not scale. Also, in all mammalian species, the mitral orifice does not offer any resistance to atrioventricular blood flow. It follows that blood flow duration is directly dependent on the distance between the atria and the ventricles. Although the heart is not a cube, this distance is defined as the third root of heart mass. The third root of any value changes little in relation to the value itself. This simple mathematic fact is an easy explanation for PR interval behavior in relation to heart and/or body size. However, the atrioventricular intranodal electrophysiology of this behavior is not known. PMID:16687954

    Full Text Available Background. The presence of anti-SSA/Ro and anti-SSB/La antibodies during pregnancy is associated with fetal congenital heart block (CHB, which is primarily diagnosed through fetal echocardiography. Conclusive information about the complete electrophysiology of the fetal cardiac conducting system is still lacking. In addition to echocardiography, fetal magnetocardiography (fMCG can be used. fMCG is the magnetic analogue of the fetal electrocardiogram (ECG. Patients and Methods. Forty-eight pregnant women were enrolled in an observational study; 16 of them tested positive for anti-SSA/Ro and anti-SSB/La antibodies. In addition to routine fetal echocardiography, fMCG was used. Fetal cardiac time intervals (fCTIs were extracted from the magnetic recordings by predefined procedures. ECGs in the neonates of the study group were performed within the first month after delivery. Results. The PQ segment of the fCTI was significantly prolonged in the study group (P=0.007, representing a delay of the electrical impulse in the atrioventricular (AV node. Other fCTIs were within normal range. None of the anti-SSA/Ro and/or anti-SSB/La fetuses progressed to a more advanced heart block during pregnancy or after birth. Conclusion. The study identified a low-risk population within antibody positive mothers, where PQ segment prolongation is associated with a lack of progression of the disease.

    2016-04-01

    Atrioventricular junction (AVJ) ablation is an effective therapy in patients with symptomatic atrial fibrillation who are intolerant to or unsuccessfully managed with rhythm control or medical rate control strategies. A drawback is that the procedure mandates a pacing system. Overall, the safety and efficacy of AVJ ablation is high with a majority of the patients reporting significant improvement in symptoms and quality-of-life measures. Risk of sudden cardiac death after device implantation is low, especially with an appropriate postprocedure pacing rate. Mortality benefit with AVJ ablation has been shown in patients with heart failure and cardiac resynchronization therapy devices. PMID:26968669

    Full Text Available A estimulação elétrica do nervo vago diminui a freqüência cardíaca e aumenta o intervalo PQ no eletrocardiograma, podendo ativar a via anterógrada do nodo atrioventricular. Neste experimento é investigada a interação da morfina sobre o controle nervoso parassimpático cardíaco em relação à dupla condução do nodo atrioventricular. A estimulação do nervo vago induz uma significativa bradicardia e um bloqueio atrioventricular de terceiro grau, com a onda P aparecendo negativa na derivação II. Devido aos efeitos moduladores da anestesia sobre o coração, administração de injeções de morfina induz o aparecimento de onda P positiva através de uma ação inibitória sobre a reentrância do nodo atrioventricular. Tudo sugere a presença de duas vias atrioventriculares, anatômica e funcionalmente distintasThat electrical stimulation of the vagus decreased heart rate and increased the PQ interval in electrocardiogram, consistent with anterograde dual atriventricular conduction. The present experiments were investigating the interaction of the morphine with cardiac parasympathetic nervous control in dual atrioventricular node. Electrical stimulation of the vagus nerve induced significant bradycardia and of third degree atrioventricular block and the P wave appearance was negative in leads II. Because background anesthesia modulates the heart, administered morphine injection the P waves appearance was positive through one inhibitory action on atrioventricular nodal reentry. All suggest the presence of two functionally and anatomically distinct atrioventricular pathways

    Objective Atrioventricular block (AVB) is a common and serious arrhythmia. At present, there is no perfect method of treatment for this kind of arrhythmia. The purpose of this study was to regenerate cardiac atrioventricular conduction by autologous transplantation of bone marrow mesenchymal stem cells (MSCs), and explore new methods for therapy of atrioventricular block. Methods Eleven Mongrel canines were randomized to MSCs transplantation (n=6) or control (n=5) group. The models of permanent and complete AVB in 11 canines were established by ablating His bundle with radiofrequency technique. At 4 weeks after AVB, bone marrow was aspirated from the iliac crest. MSCs were isolated and culture-expanded by means of gradient centrifugal and adherence to growth technique, and differentiated by 5-azacytidine in vitro. Differentiated MSCs (1ml, 1.5×107cells) labeled with BrdU were autotransplanted into His bundle area of canines by direct injection in the experimental group, and 1ml DMEM in the control group. At 1-12 weeks after operation,the effects of autologous MSCs transplantation on AVB models were evaluated by electrocardiogram, pathologic and immunohistochemical staining technique. Results Compared with the control group, there was a distinct improvement in atrioventricular conduction function in the experimental group. MSCs transplanted in His bundle were differentiated into analogous conduction system cells and endothelial cells in vivo, and established gap junction with host cardiomyocytes. Conclusions The committed-induced MSCs transplanted into His bundle area could differentiate into analogous conduction system cells and improve His conduction function in canine AVB models.

    At present, there are many pacing strategies for young patients with complete atrioventricular block. The most frequent policy is to attempt placing a dual-chamber system when possible; however, there is a group of patients that is functioning with a non-synchronous ventricular pacing, raising the question of the ideal timing to upgrade their systems. We investigated the exercise performance of a group of children and young adults with complete atrioventricular block and dual-chamber pacemakers in both single- and dual-chamber pacing modalities. A total of 15 patients performed maximal exercise stress testing after programming the VVIR or DDD modes with 2 hours of interval in a double-blind study protocol. Compared with VVIR pacing, DDD pacing resulted in increase in the peak VO2, longer test duration, major increase in the heart rate achieved during peak exercise, decreased systemic non-invasive arterial blood pressure measured at maximal exercise, higher maximal workload, prolongation of the anaerobic threshold timing, and better self-rated performance perception in all the patients. Synchronous atrioventricular pacing contributes to an increase in both the exercise performance and the performance perception in 100% of the patients. This difference contributes to create a sense of "fitness" with repercussions in the overall health, self-esteem, and life quality, as well as encourages youngster to practice sports. Our experience tends to favour upgrading patients' systems to dual-chamber systems before reaching the adolescent years, even if the centre policy is to prolong as long as possible the epicardial site in order to avoid long years of right ventricular pacing.

    Objective To investigate the effects of delayed recanalization and thrombolysis on atrioventricular(AV) block in acute inferior myocardial infarction(AIMI).Methods A total of 212 patients, including 30 patients(group A)who underwent delayed recanalization of infarct-related artery (IRA) by PTCA within 12~18 hours after onset, 50 patients(group B) who received intravenous thrombolytic therapy within 12 hours of AIMI onset, 132 patients(group C) with AIMI who received conventional therapy, were enrolled in this study.Results In group A, the occurrence of AV block was decreased significantly (26.7% vs 6.7%, P<0.01) at 24 hours after delayed recanalization of IRA by PTCA; in group B, the occurrence rate of A-V block was also decreased significantly(24.0% vs 6.0%, P<0.01) at 24 hours after thrombolytic therapy; while in group C, 28.8% patients presented A-V block at 24 hours after admission. The occurrence of AV block was significantly lower in group A than in group C(6.7% vs 28.8%, P<0.01). Compared with group C, the inpatient mortality rate in group A was also decreased by 6.5% (3.3% vs9.8%,P>O.05).Conclusion The delayed recanalization of IRA by PTCA within 12~48 hours after the onset of AIMI can reduce the incidence of A-V block and probably decrease the in-hospital mortality rate.

    Full Text Available Heart anatomy in the ostrich has been reported, but there are few information on the histological features of the atrioventricular valves. Hearts of young ostriches were fixed in 10% formaldehyde for 24 h and dissected to characterize their macroscopic anatomy. Samples of valves were harvested and stained with Mallory’s trichrome, Gomori’s trichrome, and Picro-Sirius red, for later analysis. The right atrioventricular valve consists of a muscle flap with two fixations. The left atrioventricular valve consists of two layers of endocardium with a layer of connective tissue between them. The free border of the tricuspid valve supports a varying number of chordae tendineae. One of the cusps is attached to the septum, while the other two cusps are attached to the opposite wall. The aortic valve, as well as the pulmonary trunk valve, consists of three cusps. The right atrioventricular valve showed up only as a muscle flap of myocardium coated with a thin layer of dense connective tissue, with two fixations. In the connective tissue, we find a predominance of type I collagen fibers and a lesser amount of type III, with a small presence of elastic fibers. The presence of Purkinje fibers were also usual in the valvular subendocardium, suggesting that they directly participate in the transmission of nervous stimulation to the muscle fibers within the valves. The left atrioventricular valve consisted of 3 cusps, a dorsal, a left, and a right.

    Full Text Available Background: Complete atrioventricular block (AV block is a serious complication of slow pathway ablation therapy in the treatment of atrioventricular nodal re-entrant tachycardia (AVNRT. The present study was aimed at determining whether the electroanatomical pace mapping of Koch’s triangle could significantly improve the safety, efficiency, and efficacy of selective slow pathway ablation in the treatment of AVNRT. Methods: A total number of 124 patients were selected to be studied consecutively for radiofrequency (RF ablation therapy in the treatment of AVNRT. The subjects were divided into two groups: one, designated Group 1, to serve as the control group, and the other, designated Group 2, to serve as the study group. Conventional fluoroscopic slow pathway ablation was performed on the Group 1 subjects (n=66, with the Group 2 subjects receiving slow pathway ablation therapy guided by pace mapping of Koch’s triangle. The slow pathway ablation in Group 2 (n=58 was performed with regard to the pace mapping data obtained on the basis of the St-H interval in the anteroseptal (AS, midseptal (MS, and posteroseptal (PS regions of Koch’s triangle. The anterograde fast pathway (AFP location was determined based on the shortest St-H interval obtained by stimulating the anteroseptal (AS, midseptal (MS, and posteroseptal (PS aspects of Koch’s triangle. Results: In the Group 2 subjects, AFP location was AS in 50 (86.2% of the cases, MS in 7 (12% of the cases, and PS in 1 case (1.7%. One patient with posteroseptal AFP was administered retrograde fast pathway ablation therapy. One patient in the control group (Group 1, representing 1.5% of the group, developed persistent AV block in the course of the treatment, but none of the subjects in the study group (Group 2 developed any complications. Conclusion: It was concluded that an atypical fast pathway location is conducive to the development of atrioventricular block in the ablation therapy in AVNRT

    Atrioventricular valve regurgitation (AVVR) influences morbidity and mortality in the atrioventricular canal defect (AVC). Fetal cardiac structures are subject to hemodynamic changes, as well as growth and maturation during gestation, which may alter the degree of AVVR and affect prognosis. We sought to investigate the frequency of change in degree of AVVR documented by fetal echocardiography (echo) between different periods of gestational age. Subjects with AVC seen in the Fetal Heart Program between January 2008 and September 2010 were identified. Degree of AVVR was assessed by color Doppler imaging and categorized as Grade 0 (no AVVR), Grade 1 (hemodynamically insignificant AVVR = trivial or mild), and Grade 2 (hemodynamically important AVVR = ≥moderate). Levels of AVVR between periods were compared. Forty-three fetuses were analyzed. Overall, 60 % had no change, 14 % had a decrease, and 26 % had an increase in AVVR grade. Two fetuses progressed from Grade 0 or 1 to Grade 2, while one fetus decreased from Grade 2 to Grade 0. Trisomy 21 and heterotaxy syndrome were not risk factors for AVVR progression. Transitional and incomplete canal defects may be more susceptible to AVVR progression. Sixty percent of fetuses with AVC will not exhibit progression of AVVR between the second and third trimesters of gestation. In those who exhibit change, it is most often within a hemodynamically insignificant range between none and mild regurgitation (Grades 0 and 1). These findings have implications for the counseling, follow-up, and delivery plans of the fetus with AVC defect. PMID:26238793

    In 67 consecutive patients with inferior wall acute myocardial infarction (AMI), 99m-technetium pyrophosphate scintigraphy was performed 36 to 72 hours after the onset of chest pain to detect right ventricular (RV) involvement. All patients were continuously monitored during at least 3 days to detect rhythm and conduction disturbances. In 29 patients RV involvement was diagnosed by scintigraphy. None of these 29 patients showed clinical signs of right-sided heart failure. Fourteen of the 19 patients showing atrioventricular (AV) nodal condution disturbances in the setting of inferior AMI also had RV involvement. Therefore, the incidence of high-degree AV nodal block in patients with RV involvement (14 of 29 patients) was 48% compared to only 13% (5 of 38) in patients with inferior AMI without RV involvement.

    Full Text Available The origin, stages and histogenetic processes in atrioventricular bundle were investigated. We studied the human embryonic heart from 5 to 12 week of development. Antibodies to neurofilaments, Ki-67, MSA, α-SMA and neuregulin were used. Formation of the primordia of the atrioventricular bundle depends on the chamber formation in early heart. The first morphologic reconstruction in the atrioventricular bundle starts from 5 week of gestational age. In this time we studied proximal and distal primordias, which formed general tract at 7 week. The early human heart was characterized by strong connections with atrioventricular fibrous tissue, left and right septal cuspes of mitral and tricuspidal valves. Formation of the atrioventricular bundle branches has two stages: primary and repeated growth. Median fibers are blind-ended. We suppose that atrioventricular bundle and bundle branches have extracardiac origin. Histogenesis of the atrioventricular bundle contin-ues after 12 week of human development.

    Fetal alcohol spectrum disorder (FASD), birth defects associated with ethanol exposure in utero, includes a wide spectrum of congenital heart defects (CHDs), the most prevalent of which are septal and conotruncal defects. Zebrafish FASD model was used to dissect the mechanisms underlying FASD-associated CHDs. Embryonic ethanol exposure (3-24 hours post fertilization) led to defects in atrio-ventricular (AV) valvulogenesis beginning around 37 hpf, a morphogenetic event that arises long after ethanol withdrawal. Valve leaflets of the control embryos comprised two layers of cells confined at the compact atrio-ventricular canal (AVC). Ethanol treated embryos had extended AVC and valve forming cells were found either as rows of cells spanning the AVC or as unorganized clusters near the AV boundary. Ethanol exposure reduced valve precursors at the AVC, but some ventricular cells in ethanol treated embryos exhibited few characteristics of valve precursors. Late staged larvae and juvenile fish exposed to ethanol during embryonic development had faulty AV valves. Examination of AVC morphogenesis regulatory networks revealed that early ethanol exposure disrupted the Bmp signaling gradient in the heart during valve formation. Bmp signaling was prominent at the AVC in controls, but ethanol-exposed embryos displayed active Bmp signaling throughout the ventricle. Ethanol exposure also led to mislocalization of Notch signaling cells in endocardium during AV valve formation. Normally, highly active Notch signaling cells were organized at the AVC. In ethanol-exposed embryos, highly active Notch signaling cells were dispersed throughout the ventricle. At later stages, ethanol-exposed embryos exhibited reduced Wnt/β-catenin activity at the AVC. We conclude that early embryonic ethanol exposure alters Bmp, Notch and other signaling activities during AVC differentiation leading to faulty valve morphogenesis and valve defects persist in juvenile fish.

    Signaling of bone morphogenetic protein (BMP) via type I and type II receptors is involved in multiple processes contributing to cardiogenesis. To investigate the role of the BMP type II receptor (BMPRII) in heart development, the BMPRII gene was deleted throughout the embryo during gastrulation using a Mox2-Cre transgene. BMPRII(flox/-);Mox2-Cre mice exhibited cardiac defects including double-outlet right ventricle, ventricular septal defect (VSD), atrioventricular (AV) cushion defects, and thickened valve leaflets. To characterize the tissue-specific functions of BMPRII in cardiogenesis, a series of Cre transgenes (alphaMHC-, Tie2-, Wnt1-, and SM22alpha-Cre) was employed. Interestingly, myocardial development was normal when the BMPRII gene was deleted in myocardial cells using Mox2-Cre, alphaMHC-Cre, or SM22alpha-Cre transgenes, suggesting that signaling by other BMP type II receptors may compensate for the absence of BMPRII in the myocardial cells. AV cushion defects including atrial septal defect, membranous VSD, and thickened valve leaflets were found in BMPRII(flox/-);Tie2-Cre mice. Abnormal positioning of the aorta was observed in BMPRII(flox/-);Wnt1-Cre and BMPRII(flox/-);SM22alpha-Cre mice. Taken together, these results demonstrate that endocardial BMPRII expression is required for septal formation and valvulogenesis. Moreover, mesenchymal BMPRII expression in the outflow tract cushion is required for proper positioning of the aorta. PMID:19409885

    Full Text Available Background: Radiofrequency catheter ablation (RFCA has been introduced as the treatment of choice for supraventricular tachycardia. The aim of this study was to evaluate the success rate as well as procedural and in-hospital complications of RFCA for the treatment of atrioventricular nodal reentrant tachycardia (AVNRT.Methods: Between March 1995 and February 2009, 544 patients (75.9% female, age: 48.89 ± 13.19 years underwent 548 RFCAs for AVNRT in two large university hospitals. Echocardiography was performed for all the patients before and after the procedure. Electrocardiograms were recorded on digital multichannel systems (EP-Med or Bard EP system. Anticoagulation was initiated during the procedure.Results: From the 548 patients, 36 had associated arrhythmias, atrial flutter (4%, atrial fibrillation (0.7%, concurrent atrial fibrillation and atrial flutter (0.7%, and concealed atrioventricular pathway (0.4%. The overall success rate was 99.6%. There were 21 (3.9% transient III-degree AV blocks (up to a few seconds and 4 (0.7% prolonged II- or III-degree AV blocks, 2 (0.25% of which required permanent pacemaker insertion, 3(0.5% deep vein thrombosis, and one (0.2% arteriovenous fistula following the procedure. No difference was observed in the echocardiography parameters before and after the ablation.Conclusion: RFCA had a high success rate. The complication rate was generally low and in the above-mentioned centers it was similar to those in other large centers worldwide. Echocardiography showed no difference before and after the ablation. The results from this study showed that the risk of permanent II or III-degree AV block in patients undergoing RFCA was low and deep vein thrombosis was the second important complication. There was no risk of life-threatening complications.

  2. Clarifying the atrioventricular junctional anatomy in the setting of double outlet right atrium

    Directory of Open Access Journals (Sweden)

    Saurabh Kumar Gupta

    2015-01-01

    Full Text Available Double outlet atrium is a rare cardiac anomaly wherein one of the atriums, most frequently the right atrium, opens into both the ventricles. Although seen more commonly in the setting of atrioventricular septal defect, this arrangement can also be found when one of the atrioventricular connections is atretic due to absence of the atrioventricular connection and the other atrioventricular valve straddles the muscular ventricular septum. It is the specific anatomy and connections of the atrioventricular junction that clarifies the situation and distinguishes between these two types of double outlet atrium. In this report, we present a case of double outlet right atrium co-existing with the absence of left atrioventricular connection. We then discuss the morphologic aspects of this interesting anomaly.

    Full Text Available Introduction. Complete atrioventricular block is a serious disorder, since patients may be asymptomatic. However, it is an important risk for sudden cardiac death. Case report. A 48-year old male patient was admitted to the coronary care unit, due to recurring substernal chest pain. It was followed by fatigue, weakness and confusion, it lasted more than half an hour and occurred twice. Loss of consciousness did not occur. The patient had a tick bite two months earlier. Physical examination was unremarkable, except for low heart rate (50/minute electrocardiogram showed a complete atrioventricular block with narrow QRS complexes and good ventricular function. Elevation of ST segment was observed in the inferior ECG leads, with reciprocal ST depression in precordial leads; it was highly suspicious for acute myocardial infarction, but markers of myocardial necrosis (Troponin, Creatine kinase-MB were normal. The chest pain recurred without evolutive changes in the electrocardiogram or increase in markers of myocardial necrosis. Tests for Lyme disease were negative, too. The cause of atrioventricular conduction disturbance was found by transthoracic echocardiography. A giant tumor was found in the right atrium and right ventricle. Further examinations excluded its secondary cause and the patient was sent to surgery. The tumor was inoperable and bled excessively. Although permanent pacing was performed, the patient died suddenly after dismisal. Conclusion. We can conclude that a giant primary tumor of the heart can be asymptomatic for a long time causing complete atrioventricular block, and in this case it clinically presented as acute myocardial infarction. Echocardiographic examination was the main diagnostic tool in our case. .

  7. Id4 functions downstream of Bmp signaling to restrict TCF function in endocardial cells during atrioventricular valve development.

    2016-04-01

    The atrioventricular canal (AVC) connects the atrial and ventricular chambers of the heart and its formation is critical for the development of the cardiac valves, chamber septation and formation of the cardiac conduction system. Consequently, problems in AVC formation can lead to congenital defects ranging from cardiac arrhythmia to incomplete cardiac septation. While our knowledge about early heart tube formation is relatively comprehensive, much remains to be investigated about the genes that regulate AVC formation. Here we identify a new role for the basic helix-loop-helix factor Id4 in zebrafish AVC valve development and function. id4 is first expressed in the AVC endocardium and later becomes more highly expressed in the atrial chamber. TALEN induced inactivation of id4 causes retrograde blood flow at the AV canal under heat induced stress conditions, indicating defects in AV valve function. At the molecular level, we found that id4 inactivation causes misexpression of several genes important for AVC and AV valve formation including bmp4 and spp1. We further show that id4 appears to control the number of endocardial cells that contribute to the AV valves by regulating Wnt signaling in the developing AVC endocardium. PMID:26892463

    Congestive heart failure is a severe chronic disease often associated with disorders that alter the mechanisms of excitation-contraction coupling that may result in an asynchronous left ventricular motion which may further impair the ability of the failing heart to eject blood. In recent years a therapeutic approach to resynchronize the ventricles (cardiac resynchronization therapy, CRT) has been performed through the use of a pacemaker device able to provide atrial-based biventricular stimulation. Atrial lead senses the spontaneous occurrence of cells depolarization and sends the information to the generator which, in turn, after a settled delay [atrioventricular (AV) delay], sends electrical impulses to both ventricles to stimulate their synchronous contraction. Recent studies performed on heart rate behavior of chronically implanted patients at different epochs after implantation have shown that CRT can lead to sustained overall improvement of heart function with a reduction in morbidity and mortality. At this moment, however, there are no studies about CRT effects on spontaneous heart activity of chronically implanted patients. We performed an experimental study in which the electrocardiographic signal of five subjects under chronic CRT was recorded during the activity of the pacemaker programmed at different AV delays and under spontaneous cardiac activity after pacemaker deactivation. The different behavior of heart rate variability during pacemaker activity and after pacemaker deactivation suggested the hypothesis of a phase resetting mechanism induced by the pacemaker stimulus on the sinoatrial (SA) node, a phenomenon already known in literature for aggregate of cardiac cells, but still unexplored in vivo. The constraints imposed by the nature of our study (in vivo tests) made it impossible to plan an experiment to prove our hypothesis directly. We therefore considered the best attainable result would be to prove the accordance of our data to the conjecture

    ção da Faculdade de Medicina da Universidade de São Paulo and Hospital de Beneficência Portuguesa de Ribeirão Preto, a total of 27 patients with chronic Chagas' cardiopathy, complete atrioventricular block and implanted ventricular pacemaker were upgraded to a dual-chamber pacing mode. At the beginning of the study and after 90-days periods under each pacing modes, the patients' quality of life was evaluated. Statistical analysis was made at basal, VVI and DDD conditions using the analysis of repetitive measures. RESULTS: No significant differences in the health-related quality of life, across the three studied variables (physical function, vitality and general health, were detected after the change of pacing mode from VVI to DDD. There were three cases of complications related to pacing mode upgrade: two cases of atrial tachycardia triggered to ventricles through DDD pacemaker and one atrial lead displacement. CONCLUSIONS: No benefits no quality of life were detected after the change of pacing mode VVI to DDD during elective replacement of pulse generator, in patients with Chagas' cardiomyopathy and complete AV block

  12. Fallot's tetralogy in combination with an open common atrioventricular canal

    International Nuclear Information System (INIS)

    The methods and clinics of diagnostics of Fallot tetrad (FT) combined with the opened general atrioventricular canal (AVC) of the heart are described on the basis of observation of a 6.5-year old patient and analysis of literary data. On the basis of studying clinical data, electro-, phono-, echocardiography and roentgenography, as well as heart catheterization and angiocardiography the conclusion is made that nowadays the most informative method of diagnostics of FT and AVC combination before angiocardiography is a dimer echocardiography which permits to diagnoze AVC. Angiocardiographic study proves this diagnosis and gives a precise anotomical picture of various components of this combination of heart failure

  13. Acute clenbuterol induces hypotension, atrioventricular block and cardiac asystole in the rabbit.

    Clenbuterol is a long-lasting β-adrenoceptor (β-AR) agonist and was once medicated as a bronchial dilatator, and is also used by body-building enthusiasts and athletes and in livestock breeding because of its anabolic effect on skeletal muscles and ability to promote lipolysis. Though prohibited from pharmacological uses, clenbuterol intoxication cases are frequently reported, and most of the cardiac symptoms are tachyarrhythmia. Here, we reported a different cardiovascular toxic response to clenbuterol. Using a rabbit model, we tested the dose-response pattern of the cardiovascular system to intravenous administration of clenbuterol. Routine arterial blood pressure (BP) and surface electrocardiogram (ECG) were monitored. We observed that clenbuterol at a lower dose (0.4 mg/kg, n = 3) did not significantly affect the ECG, but decreased the mean BP roughly by 15-18 mmHg. At a medial dose (3.6 mg/kg, n = 3), clenbuterol induced significant hypotension (mean BP dropped by about 30 mmHg), first-degree atrioventricular (AV) block and intermittent ectopic activities with a relatively slow rate. The hypotension and arrhythmia recovered slowly, and animals did not die. Higher-dose clenbuterol (10 mg/kg, n = 6) induced severe hypotension, second-degree AV block (Mobitz type II), 2:1 ventricular capture and progressive prolongations of P-R intervals and QRS duration, and the animals soon died of cardiac asystole. Different from other reports, we had not observed lethal tachyarrhythmia in all experiments except for the slight heart rate acceleration during the recovery stage of medial clenbuterol dosage. These results indicate that acute intravenous administration of clenbuterol has serious, dose-dependent cardiovascular toxicities and is even life threatening. PMID:22991173

    Two procedures have been traditionally used for the surgical repair of complete atrioventricular canal. The single-patch technique includes the division of valve leaflets, and the use of one patch to close the ventricular and the atrial septal defects, whereas the double-patch technique uses two separate patches, without the division of the bridging leaflets. Between 1997 and 2007, another technique emerged, the modified single-patch technique, or the 'Australian' technique, whereby the ventricular septal defect (VSD) is closed by the direct apposition of the bridging leaflets against the crest of the defect. Because of the absence of the ventricular septal patch, concerns have been raised about the possible left ventricular outflow tract obstruction (LVOTO), or atrioventricular valve (AVV) distortion, especially in case of a deep VSD, or if the defect extends superiorly. The results of the modified single-patch technique in terms of mortality, immediate and long-term AVV function and LVOTO have been similar to the standard techniques in most reports. This article will describe in detail the operative technique and review the relevant literature. PMID:26443542

  18. Effect of atrioventricular conduction on heart rate variability

    Ahmad, Talha J.

    2011-08-01

    This paper discusses the effect of atrioventricular conduction time (AVCT) on the short-term Heart Rate Variability (HRV) by computing HRV parameters using intervals between the onsets of successive P waves (PP time series) for three groups: normal, arrhythmia and sudden cardiac death (SCD) patients. A very precise wavelet transform based ECG delineator was developed to detect PP, PR and RR time series. Mean PR variation in arrhythmia and SCD group was found to be significantly high as compared to the normal group. It was observed that when PR variations in arrhythmia and SCD cases crossed a certain threshold, RR variability no longer provided a very accurate estimate of HRV. In such cases, PP variability was able to provide a better assessment of HRV. © 2011 IEEE.

    Silverman, Mark E; Upshaw, Charles B

    2002-05-15

    Walter Holbrook Gaskell was a nineteenth-century British physiologist whose investigations from 1874 until 1889 became central to our current understanding of cardiac physiology. His many cardiac contributions include the following: 1) the recognition of certain inherent properties of cardiac muscle; 2) the experimental proof that led to the acceptance of the myogenic theory of the origin of the heartbeat; 3) the mapping of the anatomy of the sympathetic nervous system; 4) the understanding of the dual autonomic control of the heart; 5) the discovery of the vasodilating effect of sympathetic stimulation on blood flow through skeletal muscle arteries; and 6) the introduction of the concept of heart block. Gaskell's elucidation of the sequence of cardiac contraction and atrioventricular block and his concepts of rhythmicity, excitability, contractility, conductivity and tonicity provided the physiologic explanation necessary for the future understanding of cardiac rhythm disturbances.

    Cyclophosphamide, an alkylation agent, is widely used in stem cell transplantation for its antineoplastic and myeloablative properties. Congestive heart failure, pericarditis, and arrhythmias are well-known cardiac sequelae of high-dose cyclophosphamide therapy; however, high-grade atrioventricular block has rarely been reported. We present the case of a 71-year-old man who developed a high degree of atrioventricular block several hours after therapy with high-dose cyclophosphamide. After tre...

    Full Text Available Pacientes com defeito septal atrioventricular de forma total (DSAVT freqüentemente apresentam insuficiência cardíaca intratável e hipertensão arterial pulmonar nos primeiros meses de vida, e apenas uma minoria sobrevive sem tratamento cirúrgico precoce. Por essa razão, indica-se a correção definitiva para alterar favoravelmente a história natural da doença. Entretanto, vários fatores são responsáveis pela alta mortalidade cirúrgica. O presente trabalho estuda a experiência na correção cirúrgica do DSAVT com o objetivo de identificar alguns fatores de risco estatisticamente significativos para a ocorrência de morte operatória. Analisaram-se, retrospectivamente, 52 pacientes submetidos, entre janeiro de 1974 e dezembro de 1990, a cirurgia definitiva para correção de DSAVT no Royal Brompton and National Heart and Lung Institute, sendo estudadas as seguintes variáveis: idade, peso, sexo, ano da operação, presença de síndrome de Down, grau de regurgitação da valva AV, bandagem prévia do tronco pulmonar, presença de anomalias associadas, pressão sistólica pulmonar, duplo orifício mitral, classificação do defeito segundo Rastelli, emprego de parada circulatória e técnica de correção (1 x 2 retalhos. Todos os fatores foram avaliados isoladamente, mediante a análise univariada. Para determinar quais os fatores que, independentemente da ação de outros, contribuíram significativamente para maior mortalidade cirúrgica, foi utilizada a análise multivariada com regressão logística. A análise multivariada demonstrou que o baixo peso na época da operação e a técnica de correção com um retalho aumentam significativamente a mortalidade cirúrgica.Patients with complete atrioventricular septal defects (CAVSD frequently present with severe heart failure which cannot be controllable medically and pulmonary hypertension in infancy. Just a small number survives without early surgical treatment. For this reason

    2015-06-01

    Discontinuities between the leaflets of the aortic and left atrioventricular valves are uncommon congenital malformations. The anomaly may be discovered during surgery without preoperative diagnosis. It represents a spectrum of anomalies that result from interruption of the normal development of the endocardial cushions during the fetal life. We describe a rare case of Down syndrome with transient complete atrioventricular block and discontinuity between the leaflets of the aortic and left atrioventricular valves without intervening fibrous band, leading to separation and detachment between them. It caused severe eccentric jet of regurgitation originated from left ventricular outflow tract and base of anterior leaflet of left atrioventricular valve into the left atrium. He underwent cardiopulmonary bypass, and the defect between left atrioventricular valve and aortic annuli was sewn. Permanent epicardial pacing was inserted during cardiac surgery. To the best of our knowledge, such a case has not been previously reported in the literature. PMID:25483555

    Fingolimod, a sphingosine 1-phosphate (S1P) receptor subtype 1, 3, 4 and 5 modulator, has been used for the treatment of patients with relapsing forms of multiple sclerosis, but atrioventricular conduction block and/or QT-interval prolongation have been reported in some patients after the first dose. In this study, we directly compared the electropharmacological profiles of fingolimod with those of siponimod, a modulator of sphingosine 1-phosphate receptor subtype 1 and 5, using in vivo guinea-pig model and in vitro human ether-a-go-go-related gene (hERG) assay to better understand the onset mechanisms of the clinically observed adverse events. Fingolimod (0.01 and 0.1 mg/kg) or siponimod (0.001 and 0.01 mg/kg) was intravenously infused over 10 min to the halothane-anaesthetized guinea pigs (n = 4), whereas the effects of fingolimod (1 μmol/L) and siponimod (1 μmol/L) on hERG current were examined (n = 3). The high doses of fingolimod and siponimod induced atrioventricular conduction block, whereas the low dose of siponimod prolonged PR interval, which was not observed by that of fingolimod. The high dose of fingolimod prolonged QT interval, which was not observed by either dose of siponimod. Meanwhile, fingolimod significantly inhibited hERG current, which was not observed by siponimod. These results suggest that S1P receptor subtype 1 in the heart could be one of the candidates for fingolimod- and siponimod-induced atrioventricular conduction block since S1P receptor subtype 5 is localized at the brain, and that direct I{sub Kr} inhibition may play a key role in fingolimod-induced QT-interval prolongation. - Highlights: • Fingolimod and siponimod are S1P{sub 1,3,4,5} and S1P{sub 1,5} receptor modulators, respectively. • Fingolimod and siponimod induced AV block in the halothane-anesthetized guinea pigs. • S1P{sub 1} in the hearts may be the target of fingolimod- and siponimod-induced AV block. • Fingolimod directly inhibited hERG current, which was not

    Science.gov (United States)

    Vanderveen, Keith B.; Talbot, Edward B.; Mayer, Laurence E.

    2008-04-08

    Nodes in a network having a plurality of nodes establish communication links with other nodes using available transmission media, as the ability to establish such links becomes available and desirable. The nodes predict when existing communications links will fail, become overloaded or otherwise degrade network effectiveness and act to establish substitute or additional links before the node's ability to communicate with the other nodes on the network is adversely affected. A node stores network topology information and programmed link establishment rules and criteria. The node evaluates characteristics that predict existing links with other nodes becoming unavailable or degraded. The node then determines whether it can form a communication link with a substitute node, in order to maintain connectivity with the network. When changing its communication links, a node broadcasts that information to the network. Other nodes update their stored topology information and consider the updated topology when establishing new communications links for themselves.

  10. BMP-2 induces versican and hyaluronan that contribute to post-EMT AV cushion cell migration.

    Directory of Open Access Journals (Sweden)

    Kei Inai

    Full Text Available Distal outgrowth and maturation of mesenchymalized endocardial cushions are critical morphogenetic events during post-EMT atrioventricular (AV valvuloseptal morphogenesis. We explored the role of BMP-2 in the regulation of valvulogenic extracellular matrix (ECM components, versican and hyaluronan (HA, and cell migration during post-EMT AV cushion distal outgrowth/expansion. We observed intense staining of versican and HA in AV cushion mesenchyme from the early cushion expansion stage, Hamburger and Hamilton (HH stage-17 to the cushion maturation stage, HH stage-29 in the chick. Based on this expression pattern we examined the role of BMP-2 in regulating versican and HA using 3D AV cushion mesenchymal cell (CMC aggregate cultures on hydrated collagen gels. BMP-2 induced versican expression and HA deposition as well as mRNA expression of versican and Has2 by CMCs in a dose dependent manner. Noggin, an antagonist of BMP, abolished BMP-2-induced versican and HA as well as mRNA expression of versican and Has2. We further examined whether BMP-2-promoted cell migration was associated with expression of versican and HA. BMP-2- promoted cell migration was significantly impaired by treatments with versican siRNA and HA oligomer. In conclusion, we provide evidence that BMP-2 induces expression of versican and HA by AV CMCs and that these ECM components contribute to BMP-2-induced CMC migration, indicating critical roles for BMP-2 in distal outgrowth/expansion of mesenchymalized AV cushions.

    This paper describes a general audio coding algorithm which has been recently standardized by AVS, China.The algorithm is based on a perceptual coding technique. The codec delivers near CD-quality audio at 128kb/s. This paper describes the coder structure in detail and discusses the reasons for specific design methods. A summary of the subjective test results are presented for the prototype codec. Comparison Mean Opinion Score (CMOS) test indicates that the quality of the AVS audio coder is comparable with MPEG Layer-3 audio coder. A real-time decoder was used for the characterization test,which is based on a 16-bit fixed-point DSP. The performance of the DSP solution was demonstrated, including computational complexity and storage characteristics.

    Full Text Available Abstract Background Echocardiography plays an integral role in the diagnosis of congestive heart failure including measurement of left heart pressure as well as mechanical dyssynchrony. Methods In this report we describe novel therapeutic uses of echo pulsed wave Doppler in atrioventricular pacemaker optimization in patients who had either not derived significant symptomatic benefit post biventricular pacemaker implantation or deteriorated after deriving initial benefit. In these patients atrioventricular optimization showed novel findings and improved cardiac output and symptoms. Results In 3 patients with Cheyne Stokes pattern of respiration echo Doppler showed worsening of mitral regurgitation during hyperpneac phase in one patient, marked E and A fusion in another patient and exaggerated ventricular interdependence in a third patient thus highlighting mechanisms of adverse effects of Cheyne Stokes respiration in patients with heart failure. All 3 patients required a very short atrioventricular delay programming for best cardiac output. In one patient with recurrent congestive heart failure post cardiac resynchronization, mitral inflow pulse wave Doppler showed no A wave until a sensed atrioventricular delay of 190 ms was reached and showed progressive improvement in mitral inflow pattern until an atrioventricular delay of 290 ms. In 2 patients atrioventricular delay as short as 50 ms was required to allow E and A separation and prevent diastolic mitral regurgitation. All patients developed marked improvement in congestive heart failure symptoms post echo-guided biv pacemaker optimization. Conclusion These findings highlight the value of echo-guided pacemaker optimization in symptomatic patients post cardiac resynchronization treatment.

    Full Text Available Ultralyd billeddanning er i dag den beste undersøkelsesmetoden vi har til å overvåke fosterets utvikling og vekst. Ultralydmåling av fosterets størrelse og biometriske referansetabeller for svangerskapet brukes til å fastsette svangerskapets alder, beregne termin og vurdere fosterets vekst. Optimal studiedesign er ulik for hvert av disse formålene. Det er stor variasjon i fysiologisk vekst og en utfordring å identifisere fostre som har dårlig tilvekst. En enkeltmåling av fosteret kan fortelle oss om det er lite eller stort i forhold til andre fostre, men ikke om størrelsen er passelig i forhold til forventet fysiologisk vekst for dette fosteret. Tilpassede referansemodeller ("customised" justerer forventet størrelse i relasjon til føtale og maternelle faktorer og har vist seg å bedre identifisere sanne veksthemmede fostre enn bare å klassifisere i henhold til 2,5, 5 eller 10 persentilen. Men et foster som i utgangspunktet er stort for alderen, men etter hvert vokser langsomt vil ikke nødvendigvis bli fanget opp ved en slik enkeltmåling. Serielle målinger vil hjelpe, men en slik longitudinell metode blir ikke fullt ut utnyttet før det appliseres betinget ("conditional" vekstberegning. Betingelsesleddene for variasjon i vekst og målemetode kalkuleres ut fra longitudinelle data og kan så anvendes for det enkelte foster.

    Atrioventricular reciprocating tachycardia is a common cause of undifferentiated supraventricular tachycardia. In patients with manifest or concealed accessory pathways, it is imperative to assess for the presence of other accessory pathways. Multiple accessory pathways are present in 4% to 10% of patients and are more common in patients with structural heart disease. In rare cases, multiple accessory pathways can act as the anterograde and retrograde limbs of the tachycardia. PMID:26920167

    Changes of the PR interval (atrioventricular delay) in relation to changes of heart size in mammalian species (scaling) confront us with a perplexing lack of understanding of an essential funetion of the heart. The PR interval controls the duration of late diastolic blood flow from the atria to the ventricles. There is good evidence that blood flow velocity is fairly constant in all mammalian species, meaning it does not scale. Also, in all mammalian species, the mitral orifice does not offer...

    Bigdelian, Hamid; Sedighi, Mohsen

    2016-01-01

    Background Tetralogy of Fallot (TOF) is a well-recognized congenital heart disease. Despite improvements in the outcomes of surgical repair, the optimal timing of surgery and type of surgical management of patients with TOF remains controversial. The purpose of this study was to assess outcomes following the repair of TOF in infants depending on the surgical procedure used. Methods This study involved the retrospective review of 120 patients who underwent TOF repair between 2010 and 2013. Patients were divided into three groups depending on the surgical procedure that they underwent. Corrective surgery was done via the transventricular approach (n=40), the transatrial approach (n=40), or a combined atrioventricular approach (n=40). Demographic data and the outcomes of the surgical procedures were compared among the groups. Results In the atrioventricular group, the incidence of the following complications was found to be significantly lower than in the other groups: complete heart block (p=0.034), right ventricular failure (p=0.027) and mediastinal bleeding (p=0.007). Patients in the atrioventricular group had a better postoperative right ventricular ejection fraction (p=0.001). No statistically significant differences were observed among the three surgical groups in the occurrence of tachycardia, renal failure, and tricuspid incompetence. The one-year survival rates in the three groups were 95%, 90%, and 97.5%, respectively (p=0.395). Conclusion Combined atrioventricular repair of TOF in infancy can be safely performed, with acceptable surgical risk, a low incidence of reoperation, good ventricular function outcomes, and an excellent survival rate.

    Full Text Available Background/Aim. Cardiac resynchronization therapy (CRT improves ventricular dyssynchrony and is associated with an improvement in symptoms, quality of life and prognosis in patients with severe heart failure and intraventricular conduction delay. Different pacing modalities produce variable activation patterns and may be a cause of different haemodynamic changes. The aim of our study was to investigate acute haemodynamic changes with different CRT configurations during optimization procedure. Methods. This study included 30 patients with severe left ventricular systolic dysfunction and left bundle branch block with wide QRS (EF 24.33 ± 3.7%, QRS 159 ± 17.3 ms, New York Heart Association III/IV 25/5 with implanted CRT device. The whole group of patients had severe mitral regurgitation in order to measure dP/dt. After implantation and before discharge all the patients underwent optimization procedure guided by Doppler echocardiography. Left and right ventricular pre-ejection intervals (LVPEI and RVPEI, interventricular mechanical delay (IVD and the maximal rate of ventricular pressure rise during early systole (max dP/dt were measured during left and biventricular pacing with three different atrioventricular (AV delays. Results. After CRT device optimization, optimal AV delay and CRT mode were defined. Left ventricular pre-ejection intervals changed from 170.5 ± 24.6 to 145.9 ± 9.5 (p < 0.001, RVPEI from 102.4 ± 15.9 to 119.8 ± 10.9 (p < 0.001, IVD from 68.1 ± 18.3 to 26.5 ± 8.2 (p < 0.001 and dP/dt from 524.2 ± 67 to 678.2 ± 88.5 (p < 0.01. Conclusion. In patients receiving CRT echocardiographic assessment of the acute haemodynamic response to CRT is a useful tool in optimization procedure. The variability of Doppler parameters with different CRT modalities emphasizes the necessity of individualized approach in optimization procedure.

    Hva skal til for å lære av erfaring? Denne avhandlingen er en empirisk baseret undersøkelse av ungdosmskolelæreres muligheter og betingelser for å "lære av erfaring" i den særlige betydning av begrepet  W. Bion gir i sin psykoanalytiske teori. Undersøgelsen baserer seg på et feltarbeid som strekker...... seg over ett skoleår. Datamaterialet ble samlet inn via observerasjoner og mer eller mindre strukturerte samtaler med lærere ved to forskellige norske ungdsomsskoler. Analysen av materialet foregår i to trinn: først en fenomenologisk analyse, tett på lærernes egne beskrivelser og refleksjoner av...... lærerarbeidet, dets udfordringer og vanskeligheter, og deretter en psykoanalytisk perspektivering av de fenomenologiske analyseresultatene. Analysen viser en almindelig lærerhverdag og en skoleorganisation, hvor lærernes "læring av erfaring" i stor utstrekning blokkeres i et vekselspill mellem lærernes flukt...

    Cardiac involvement in systemic echinococcosis is a rare phenomenon. Abnormalities of the cardiac conduction system are an exceptional feature of cardiac hydatidosis. We report, to the best of our knowledge, the first case of cardiac hydatidosis from Pakistan in a 30 year old male who presented with recurrent syncopal episodes due to complete atrioventricular conduction block and subsequently underwent implantation of dual chamber pacemaker. His transthoracic echocardiogram revealed a large, well circumscribed, interventricular septal mass which was avascular on subsequent perfusion imaging. Surgical resection of the mass three years later confirmed it to be a hydatid cyst. PMID:22764470

    Scaling can be defined as the adjustment of a structure, a function, or an organ to the size of the mammalian body. An example is the size of the heart in relation to the size of the body. The duration of the PR interval on the electrocardiogram (atrioventricular delay) in relation to the size of the heart is a perplexing example of scaling. During evolution, mammalian species changed their shape, size, and function while adapting to the habitat in which they had to live and survive. This rev...

    Science.gov (United States)

    Amara, W

    2013-11-01

    In this article, we describe a case of ventricular asystole in a patient implanted with a cardiac pacemaker. The patient had a device replacement. The new pacemaker has been connected to old unipolar leads. The detection has been, inadvertently, programmed in a bipolar mode. This programmation induced an inhibition of the atrial and ventricular pacing due to oversensing of myopotentials. An inhibition of ventricular stimulation has been recorded also because of ventricular detection of the unipolar atrial stimulation (atrioventricular crosstalk). Lack of ventricular stimulation induced in this dependant patient ventricular asystole and syncope. PMID:24055198

    The lymph node staging is a very important prognostic parameter for patients with presenting with head neck cancer and is influencing the selection of the different therapeutic strategies including surgery, chemotherapy, radiotherapy or a combination of them. The accuracy of imaging techniques, such as US, MR imaging, and CT, depends on the appropriateness of radiological criteria used for diagnosing lymph node metastases. Size of nodes and evidence of necrosis are still the most important radiological criteria. However, the size shows great variability. A spherical lymph node larger than 10 mm is an indicator for a malignant node, whereas an oval shape and/or a fatty hilus are more benign signs. But there are many limitations and different cut offs published in the literature, indicating that the size of a lymph node is not a reliable criteria for the assessment of lymph nodes in the head and neck region. Today new high-resolution MRI sequences and the development of specific contrast agents are offering new possibilities in the diagnostic work-up of head and neck lymph nodes. Ultrasmall superparamagnetic iron oxide particles (USPIO's) are resulting after intravenous application in a reduction of the T2 relaxation time. This is causing a signal decrease on T2-weighted MR images in benign lymph nodes after administration of USPIO's, whereas malignant lymph nodes do not show a significant signal decrease. Some clinical studies presented already very promising results. Based on the fact, that the size evaluation of lymph nodes in the head and neck has not changed during the last decade, this paper will mainly focus on MRI with new contrast agents and new techniques as diffusion weighted imaging (DWI)

  3. A Heart too Drunk to Drive; AV Block following Acute Alcohol Intoxication.

    Acute excessive alcohol consumption is associated with heart rhythm disorders like atrial fibrillation but also premature ventricular contractions, collectively known as the "holiday heart syndrome". More rarely but clinically significant are reports of atrioventricular (AV) conduction disturbances in binge drinkers with no underlying heart disease or chronic alcohol consumption. To obtain better insights into common denominators and the potential underlying mechanisms we collected and compared individual case reports of AV block following acute alcohol intoxication in otherwise healthy people. By screening PubMed, Google Scholar, Scopus and JSTOR, fifteen cases were found of which eight were sufficiently documented for full analysis. Blood alcohol levels ranged from 90 to 958 mg/dl (19 to 205 mM). Second and third degree AV block was observed most (6/8) albeit that in two of these patients a vagal stimulus led to deterioration from first into higher order AV block. In all cases, patients reverted to normal sinus rhythm upon becoming sober again. Mildly lowered body temperature (35.9 ± 0.5°C) was observed but can be excluded as a major cause of conduction blockade. We hypothesize that ethanol induced partial inhibition of calcium and potentially also sodium currents in conductive tissue structures may be one of the mechanisms of conduction slowing and block that may become exaggerated upon increased vagal tone. An impairment of gap junction function cannot be excluded as a contributing factor. In conclusion, cases of documented alcohol induced AV block are very rare but events can occur at relatively low serum alcohol levels which should prompt to awareness of this phenomenon in alcohol intoxicated patients.

  12. The state of the left atrium in the open atrioventricular canal

    International Nuclear Information System (INIS)

    A study was made of the state of the left atrium in different forms of the open atrioventricular canal (AVC). X-ray signs of enlargment of the left atrium were revealed in 52% of patients. This enlargement indicated, as a rule, the presence of insufficiency of the split anteromedian cusp of the mitral valve in combination with a small left-to-right shunt or to volumetric overexertion of the left atrium as a result of a marked left ventricular-right atrial or interventricular shunt. The enlargement of the left atrium on X-ray films should not be regarded as a pathognomic sign of AVC hoever it shoul be taken into account in differential diagnosis and planning of an area of radiosurgical investigation

    A 23-year-young female presented with mild exertional dyspnoea and palpitation since early childhood. By deploying 2D- and 3D echocardiography, she was detected to have situs solitus, atrioventricular and ventriculoarterial discordance with L-malposition of great vessels, valvular pulmonary stenosis, large secundum atrial septal defect, bicuspid aortic valve, right-sided aortic arch, and moderately severe mitral and tricuspid valve regurgitation. Typical parachute deformities of the morphologically mitral and tricuspid valves were observed. 3D echocardiography revealed a single papillary muscle in the morphologically left ventricle placed anteriorly and providing insertion to tendinous cords and only a moderator band with no other muscle bundles in the morphologically right ventricle placed posteriorly and providing attachment to two strings of cords. Considering the minimal symptoms, conservative treatment was pursued. PMID:26702687

    During early embryogenesis, the formation of the cardiac atrioventricular canal (AVC) facilitates the transition of the heart from a linear tube into a chambered organ. However, the genetic pathways underlying this developmental process are poorly understood. The T-box transcription factor Tbx20 is expressed predominantly in the AVC of early heart tube. It was shown that Tbx20 activates Nmyc1 and suppresses Tbx2 expression to promote proliferation and specification of the atrial and ventricul...

    AIM: To evaluate predictors of asymptomatic atrial fibrillation in patients older than 70 years with complete atrioventricular (AV) block, normal left ventricular systolic function, and implanted dual chamber (DDD) pacemaker. METHODS: Hundred and eighty six patients with complete AV block were admitted over one year to the Sisters of Mercy University Hospital. The study recruited patients older than 70 years, with no history of atrial fibrillation, heart failure, or reduced left ventricular systolic function. All the patients were implanted with the same pacemaker. Out of 103 patients who were eligible for the study, 81 (78%) were evaluated. Among those 81 (78%) were evaluated. Eighty one (78%) patients were evaluated. Follow-up time ranged from 12 to 33 months (average +\\/-standard deviation 23 +\\/- 5 months). Primary end-point was asymptomatic atrial fibrillation occurrence recorded by the pacemaker. Atrial fibrillation occurrence was defined as atrial high rate episodes (AHRE) lasting >5 minutes. Binary logistic regression was used to identify the predictors of development of asymptomatic atrial fibrillation. Results. The 81 patients were stratified into two groups depending on the presence of AHRE lasting >5 minutes (group 1 had AHRE>5 minutes and group 2 AHRE<5 minutes). AHRE lasting >5 minutes were detected in 49 (60%) patients after 3 months and in 53 (65%) patients after 18 moths. After 3 months, only hypertension (odds ratio [OR], 17.63; P = 0.020) was identified as a predictor of asymptomatic atrial fibrillation. After 18 months, hypertension (OR, 14.0; P = 0.036), P wave duration >100 ms in 12 lead ECG (OR, 16.5; P = 0.001), and intracardial atrial electrogram signal amplitude >4 mV (OR, 4.27; P = 0.045) were identified as predictors of atrial fibrillation. CONCLUSION: In our study population, hypertension was the most robust and constant predictor of asymptomatic atrial fibrillation after 3 months, while P wave duration >100 ms in 12-lead ECG and

    2014-01-01

    Recent advances in graph theory suggest that is possible to identify the oldest nodes of a network using only the graph topology. Here we report on applications to heterogeneous real world networks. To this end, and in order to gain new insights, we propose the theoretical framework of the Estrada communicability. We apply it to two technological networks (an underground, the diffusion of a software worm in a LAN) and to a third network representing a cholera outbreak. In spite of errors introduced in the adjacency matrix of their graphs, the identification of the oldest nodes is feasible, within a small margin of error, and extremely simple. Utilizations include the search of the initial disease-spreader (patient zero problem), rumors in social networks, malware in computer networks, triggering events in blackouts, oldest urban sites recognition.

  14. Congenital complete atrioventricular block. Report of one case and literature review

    International Nuclear Information System (INIS)

    Complete congenital atrioventricular block is a rare entity that has a high morbidity and mortality. Its real incidence remains unknown and a high suspicion index is needed for its diagnosis and consequently for its early intervention. It is observed in children of mothers having connective tissue autoimmune diseases, in particular systemic lupus erythematosus, when the condition is congenital. If it is post-natal, congenital cardiopathies are responsible in most cases. It may al so appear in. structurally normal hearts. The characteristic clinical finding is persistent bradycardia manifested since intrauterine life and affecting the circulatory fetal stability, going as far as to produce hydrops fetalis, a serious and lethal condition. After birth, it appears with bradycardia as well, that may or not unbalance the patient hemodynamics. Diagnosis is made upon clinical suspicion with fetal echocardiography and when post-natal, through electrocardiogram and maternal antibody type antiRo and antiLa. Pacemaker implantation is the definitive treatment that contributes to improve patient survival and prognosis. We present the case of a premature female patient with 31 weeks of gestation due to non-immune hydrops in who complete atrioventricuiar block secondary to maternal lupus erythematosus confirmed by frankly positive anti-nuclear antibodies and positive antiRo and antiLa antibodies was diagnosed, and that received inotropic support after pace maker implantation. She improved completely from her heart failure and was sent to other institution for conventional management of premature

  15. Pulmonary stenosis development and reduction of pulmonary arterial hypertension in atrioventricular septal defect: a case report

    Directory of Open Access Journals (Sweden)

    Ninet Gérard

    2009-09-01

    Full Text Available Abstract A 24-year-old patient was admitted for dyspnoea and syncope. He had a previous history of complete atrio-ventricular septal defect and trisomy 21. At the age of 6 months, in 1984, cardiac catheterization revealed a quasi-systemic pulmonary arterial hypertension with a bidirectional shunt corresponding to an Eisenmenger syndrome. Corrective cardiac surgery was not performed at this time because surgical risk was considered too high. Until the age of 20 years old, he showed few symptoms while under medical treatment. But since 2006, his functional status became worse with an increased dyspnoea, syncopes, and severe cyanosis. In these conditions, haemodynamic parameters have been re-evaluated in 2006 and 2008. They highlighted a late and progressive development of a valvular and infundibular pulmonary stenosis leading to a normalisation of pulmonary arterial pressures. At the age of 24 , the patient underwent corrective cardiac surgery which was successful. Late development of both infundibular and valvular pulmonary stenosis have not been described before in non operated congenital ventricular septal defects, but development of one or the other abnormality would be found in 8% of patients. The physiopathological mechanism of this obstruction is unclear. Nevertheless, in unoperated congenital cardiac shunt lesions, reversibility of severe pulmonary arterial hypertension should be reconidered and re-assessed during follow up.

  16. Evaluation of atrial, ventricular and atrioventricular septal defects by cine magnetic resonance imaging

    International Nuclear Information System (INIS)

    Cine magnetic resonance imaging (MRI) was performed on 20 patients (mean age: 5.3±4.4 years) with atrial, ventricular, or atrioventricular septal defects for evaluation of cardiac structure and blood flow. Prior to cine MRI, electrocardiographycally gated MRI using multislice scquisition was performed on all patients to localize optimal slice location. Cine-MRI was obtained with a 30 deg flip angle, 15 msec echo time, and 30 msec pulse repetition time, on a 256 x 256 or 128 x 128 acquisition matrix. Abnormalities of cardiac structure were well defined in all patients by gated cardiac imaging. In 18 of the 20 patients, cine-MRI was able to detect shunt flow, visualized as a low intensity signal in comparison with the surrounding blood flow. Cine-MRI can provide not only accurate anatomy of cardiac structures but functional assessment of the cardiac chamber, wall topology and flow relations. Cine-MRI will become an important noninvasive technique for assessment of anatomy and physiology in congenital heart disease. (author)

    Full Text Available Atrial fibrillation (AF is the most common cardiac arrhythmia and despite advancements in rhythm control through direct catheter ablation, maintaining sinus rhythm is currently not possible in a large proportion of AF patients. Furthermore, in some instances pharmacological rate control may be insufficient, resulting in a highly symptomatic patient at risk of developing tachycardia-induced cardiomyopathy and heart failure (HF. Catheter ablation of the atrioventricular junction (AVJ with subsequent permanent pacemaker implantation provides definite rate control and represents an attractive therapeutic option when pharmacological rate control is not achieved. In those with reduced ventricular function, cardiac resynchronization therapy (CRT should be considered over right ventricular apical (RVA pacing in order to avoid the deleterious effects associated with a high amount of chronic RVA pacing. Another group of patients that may also benefit from AVJ ablation are HF patients with concomitant AF receiving CRT. In this patient cohort AVJ ablation ensures near 100% biventricular pacing, thus allowing optimization of the therapeutic effects of CRT.

  19. Lymph node imaging by ultrarapid 3D angiography

    International Nuclear Information System (INIS)

    Purpose: A report on observations of lymph node images obtained by gadolinium-enhanced 3D MR angiography (MRA). Methods: Ultrarapid MRA (TR, TE, FA - 5 or 6.4 ms, 1.9 or 2.8 ms, 30-40 degrees) with 0.2 mmol/kg BW Gd-DTPA and 20 ml physiological saline. Start after completion of injection. Single series of the pelvis-thigh as well as head-neck regions by use of a phased array coil with a 1.5 T Magnetom Vision or a 1.0 T Magnetom Harmony (Siemens, Erlangen). We report on lymph node imaging in 4 patients, 2 of whom exhibited benign changes and 2 further metastases. In 1 patient with extensive lymph node metastases of a malignant melanoma, color-Doppler sonography as color-flow angiography (CFA) was used as a comparative method. Results: Lymph node imaging by contrast medium-enhanced ultrarapid 3D MRA apparently resulted from their vessels. Thus, arterially-supplied metastases and inflammatory enlarged lymph nodes were well visualized while those with a.v. shunts or poor vascular supply in tumor necroses were poorly imaged. Conclusions: Further investigations are required with regard to the visualization of lymph nodes in other parts of the body as well as a possible differentiation between benign and malignant lesions.

    The Arctic Visiting Speakers (AVS) Series funds researchers and other arctic experts to travel and share their knowledge in communities where they might not otherwise connect. Speakers cover a wide range of arctic research topics and can address a variety of audiences including K-12 students, graduate and undergraduate students, and the general public. Host applications are accepted on an on-going basis, depending on funding availability. Applications need to be submitted at least 1 month prior to the expected tour dates. Interested hosts can choose speakers from an online Speakers Bureau or invite a speaker of their choice. Preference is given to individuals and organizations to host speakers that reach a broad audience and the general public. AVS tours are encouraged to span several days, allowing ample time for interactions with faculty, students, local media, and community members. Applications for both domestic and international visits will be considered. Applications for international visits should involve participation of more than one host organization and must include either a US-based speaker or a US-based organization. This is a small but important program that educates the public about Arctic issues. There have been 27 tours since 2007 that have impacted communities across the globe including: Gatineau, Quebec Canada; St. Petersburg, Russia; Piscataway, New Jersey; Cordova, Alaska; Nuuk, Greenland; Elizabethtown, Pennsylvania; Oslo, Norway; Inari, Finland; Borgarnes, Iceland; San Francisco, California and Wolcott, Vermont to name a few. Tours have included lectures to K-12 schools, college and university students, tribal organizations, Boy Scout troops, science center and museum patrons, and the general public. There are approximately 300 attendees enjoying each AVS tour, roughly 4100 people have been reached since 2007. The expectations for each tour are extremely manageable. Hosts must submit a schedule of events and a tour summary to be posted online

    Full Text Available OBJETIVO: Verificar se a persistência de salto nodal relaciona-se à taxa de recorrência de taquicardia por reentrada nodal (TRN após ablação com radiofreqüência (RF da via lenta do nó atrioventricular. MÉTODOS: Num seguimento de 20±12 meses, foi analisada a recorrência de TRN em 126 pacientes consecutivos submetidos a ablação com RF da via lenta nodal. O critério de interrupção do procedimento foi a não reindução da TRN, após estimulação atrial programada, com e sem isoproterenol intravenoso. Ao final do procedimento, 98 pacientes não apresentavam salto nodal, e em 28 persistia o salto nodal e/ou o eco atrial. RESULTADOS: Houve recorrência clínica de TRN em 15 (11% pacientes: 9 no grupo sem salto nodal e/ou eco atrial e em 6 do grupo que persistiu com salto e/ou eco atrial. A recorrência tendeu a ser maior no 2º grupo (9% vs 21%, mas não houve significância estatística entre os resultados (p=0,09. CONCLUSÃO: Desde que a TRN não possa ser induzida após a infusão de isoproterenol, a recorrência espontânea da arritmia após a ablação por RF da via lenta nodal não é diferente entre pacientes que persistem ou não com salto nodal e/ou eco atrial.PURPOSE: The aim of this study is to verify whether the persistence of conduction over the slow pathway is related to an increased trend for recurrence. METHODS: Recurrence rate was retrospectively analyzed in 126 patients who underwent slow pathway radiofrequency (RF catheter ablation during a follow-up of 20±12 months. The ablative procedure was interrupted when AVNRT was no longer induced by atrial stimulation after intravenous infusion of isoproterenol. Ninety-eight patients had no evidence of slow pathway whereas 28 patients persisted with AV node jump and atrial echo beat. RESULTS: There were 15 recurrences: 9% of those who had no evidence of slow pathway (9 of 98 patients and 21% of those with AV node jump and/or atrial echo beat but this difference was not

This study was designed to determine the effect of primary percutaneous coronary intervention (PCI in patients with CAVB complicating acute inferior STEMI, at a single center.Methods: We enrolled 138 consecutive patients diagnosed with STEMI involving the inferior wall; of these, 27 patients had CAVB. All patients received primary PCI. The clinical characteristics, procedural data, and clinical outcomes were compared in patients with versus without CAVB. Results: Baseline clinical characteristics were similar between patients with and without CAVB. Patients with CAVB were more likely to present with cardiogenic shock, and CAVB was caused primarily by right coronary artery occlusion. Door-to-balloon time was similar between those two groups. After primary PCI, CAVB was reversed in all patients. The peak creatinine phosphokinase level, left ventricular ejection fraction and in-hospital mortality rate were similar between the two groups. After a median follow up of 318 days, major adverse cardiac events did not differ between the groups (8.1% in patients without CAVB; 11.1% in patients with CAVB (P=0.702.Conclusion: We conclude that primary PCI can ameliorate CAVB-complicated acute inferior STEMI, with an acceptable rate of major adverse cardiac events, and suggest that primary PCI should be the preferred reperfusion therapy in patients with CAVB complicating acute inferior myocardial infarction.

    I løpet av de siste årene har relasjonelle databaser mistet litt av sin popularitet hos noen av de mest innflytelsesrike aktørene innen informasjonsteknologi. Sent i 1990-årene, og tidlig i 2000-årene opplevde vi en stor endring innen kommunikasjon. I starten var det meste av nettsider read-only. Typisk ville en person lage en nettside med innhold. Deretter ville brukere lese innholdet. Etterhvert gikk man mer og mer bort fra read-only mønsteret, og skapte sosiale nettverk hvor brukerne selv ...

  12. Atrioventricular Conduction Delay in the Second Trimester Measured by Fetal Magnetocardiography

    Full Text Available Introduction. Fetal AV block in SSA/Ro pregnancies is generally not seen before 18-week gestation and onset is rare after 28-week gestation. If complete AV block appears, it is believed to be irreversible. The purpose of the study was to evaluate precise electrophysiological AV conduction from 18-week gestation onwards. Patients and Methods. 21 fetuses of pregnant women with collagen vascular diseases were included in the study group and 59 healthy fetuses served as controls. In addition to fetal echocardiography, fetal magnetocardiography (fMCG was used to investigate precise electrophysiological fetal cardiac time intervals (fCTIs. Results. The PR segment (isoelectric segment between the end of the P wave and the start of the QRS complex was significantly prolonged (P<0.036 2nd trimester, P<0.023 3rd trimester in both trimesters within the study group. In fetuses less than 23-week gestational age, a nearly complete separation was found, where a PR segment of 60 ms or greater completely excluded control fetuses. All other fCTIs did not differ significantly. None of the fetuses progressed to a more advanced heart block. Conclusion. Slight antibody effects in pregnancy, leading to PR segment prolongation, can already be seen from 18-week gestation onwards by fMCG. Serial fetal Doppler echocardiography and additional fMCG can be useful methods to measure early and precise AV conduction time, to achieve best surveillance for these high-risk pregnancies.

    Full Text Available Arvelig hemokromatose fører til jernopphopning i kroppen, men gir sjelden alvorlig helseskade. Nesten alle hemokromatosepasienter i vårt land er homozygote for C282Y-mutasjonen i HFE-genet. Omtrent 7 per 1000 innbyggere har denne genotypen. Alvorlig syke blir bare omkring 5-15% av homozygote menn og nesten ingen kvinner. Likevel er det holdepunkter for at screening for hemokromatose blant friske, yngre menn kan være kostnadseffektivt. Det er relativt lett å påvise om en person er disponert for sykdommen, i god tid før den bryter ut, og forebyggende behandling er billig og effektiv. Imidlertid kan vi ikke forutsi hvilke screeningpositive personer som ubehandlet får alvorlig sykdom. Et kontrollert forsøk med screening bør gjennomføresHereditary hemochromatosis – benefits of screening. Hereditary hemochromatosis leads to iron accumulation in the body; however, serious illness due to hemochromatosis is rare. In Norway, almost all patients with hemochromatosis are homozygous for the C282Ymutation in the HFE-gene, a genotype carried by about 7 per 1000 inhabitants. Serious complications are seen in only about 5-15% of homozygous men and in very few women. Nevertheless, screening young men for hemochromatosis may be cost-effective. Detecting predisposed men is relatively straightforward, and prophylactic treatment is cheap and effective. However, we can not predict, among screen-positive men, the few who untreated will become seriously ill. A controlled screening trial should be conducted.

    Full Text Available OBJECTIVE: To study mitral valve function in the postoperative period after correction of the partial form of atrioventricular septal defect. METHODS: Fifty patients underwent surgical correction of the partial form of atrioventricular septal defect. Their mean age was 11.8 years and 62% of the patients were males. Preoperative echocardiography showed moderate and severe mitral insufficiency in 44% of the patients. The mitral valve cleft was sutured in 45 (90% patients (group II - GII. Echocardiographies were performed in the early postoperative period, and 6 and 12 months after hospital discharge. RESULTS: The patients who had some type of arrhythmia in the postoperative period had ostium primum atrial septal defect of a larger size (2.74 x 2.08 cm. All 5 patients in group I (GI, who did not undergo closure of the cleft, had a competent mitral valve or mild mitral insufficiency in the preoperative period. One of these patients began to have moderate mitral insufficiency in the postoperative period. On the other hand, in GII, 88.8% and 82.2% of the patients had competent mitral valve or mild mitral insufficiency in the early and late postoperative periods, respectively. CONCLUSION: The mitral valve cleft was repaired in 90% of cases. Echocardiography revealed competent mitral valve or mild mitral insufficiency in 88.8% and 82.2% of GII patients in the early and late postoperative periods, respectively.

    Atrioventricular canal defects (AVCD) constitute the predominant congenital heart defect in Down`s syndrome. For this reason, a candidate gene involved in atrioventricular canal development was previously searched and excluded in dominant pedigrees of AVCD, using linkage analysis of polymorphisms from chromosome 21. Because of the striking association between 8p deletion and AVCD, a search for an AVCD gene was carried out in two pedigrees of individuals with autosomal dominant AVCD using a set of DNA markers of the 8pter{r_arrow}q12 region. These two families include affected individuals and subjects who have transmitted the defect but are not clinically affected. Two-point lod scores were significantly negative for all markers at penetrance levels of 90% and 50%. Multipoint analysis excluded the region covered by the markers LPL-D8S262 and 30 cM to either side of this area. This result corroborates heterogeneity of this heart defect and indicates that the genetic basis of familial AVCD is different from AVCD associated to either trisomy 21 or 8p deletion. 25 refs., 3 figs., 2 tabs.

  8. Sonography of neck lymph nodes. Part II: abnormal lymph nodes

    International Nuclear Information System (INIS)

    Assessment of cervical lymph nodes is essential for patients with head and neck carcinomas, and ultrasound is a useful imaging technique. Sonographic features that help distinguish between the causes of neck lymphadenopathy, including grey scale and Doppler features, are discussed. In addition to the distribution and location of nodes, the useful grey-scale features are: size, shape, internal architecture, intranodal necrosis, absence of hilar structure and calcification. The useful Doppler features are: distribution of vascularity and intranodal resistance. Ancillary features such as oedema of soft tissue and nodal matting are particularly helpful to identify tuberculous nodes

  9. Vagal postganglionic innervation of the canine sinoatrial node.

    1987-07-01

    Differential, selective distribution of parasympathetic, postganglionic innervation to the atrioventricular nodal (AVN) region of the canine heart was recently described. Ablation of parasympathetic pathways to the AVN by disruption of the epicardial fat pad at the junction of the inferior vena cava and inferior left atrium did not interfere with normal vagal control of the sinoatrial node (SAN) function. In sharp contrast, surgical dissection of the fat pad overlying the right pulmonary vein-left atrial junction interrupted the major right and left vagal inputs to the SAN region. The pulmonary vein fat pad (PVFP) in the dog heart is triangular in shape with roughly equilateral dimensions of approximately 1 cm, its base extending from superior to inferior veins, and its apex extending nearly to the sinus nodal artery as it courses rostrally in the sulcus terminalis. Careful dissection of smaller fat pads around the circumference of the pulmonary veins and particularly over the rostral-dorsal surfaces of the right superior pulmonary vein and adjacent right atrium, completed SAN parasympathetic denervation. Care in making these dissections left the vagal supply to the AVN region essentially intact, and preserved the sympathetic supplies to both SAN and AVN regions. Autonomic ganglia, varying in size from 1 or 2 cells to 80-100 cells, were found scattered throughout the ventral PVFP (overlying and surrounding the right pulmonary vein-left atrial junction). The ganglia were generally imbedded in fatty connective tissue, although they commonly rested very close to, or were loosely surrounded by epicardial muscle. Ganglia were also found in smaller fat pads on the dorsal surfaces of the atrium between the azygos and the right superior pulmonary vein. PMID:3655182

  12. Genetics and Sinus Node Dysfunction

    Directory of Open Access Journals (Sweden)

    Eyal Nof MD

    2009-04-01

    Full Text Available Sinus node dysfunction (SND is commonly encountered in the clinic. The clinical phenotype ranges from asymptomatic sinus bradycardia to complete atrial standstill. In some cases, sinus bradycardia is associated with other myocardial conditions such as congenital abnormalities, myocarditis, dystrophies, cardiomyopathies as well as fibrosis or other structural remodeling of the SA node.1-8 Although there are many etiologies for symptomatic slow heart rates, the only effective treatment available today is the implantation of a pacemaker. The predominant ion channel currents contributing to the pacemaker activity in the sinoatrial node (SAN include currents flowing through hyperpolarization-activated, cyclic nucleotide-gated (HCN channels,9 L- type Ca, T- type Ca,10 delayed rectifier K,1112 and acetylcholine (ACh-activated13,14 channels. However, their relative contribution remains a matter of debate and the cellular mechanisms contributing to abnormal sinus node function leading to bradycardia are not fully elucidated. Sodium channel current (INa, encoded by SCN5A, is responsible for the cardiac action potential (AP upstroke and therefore has an important role in initiation and propagation of the cardiac action potential. Although it is largely absent in the sinus node, it plays an important role at the periphery of the sinus node in transmitting electrical activity from the sinus node to the rest of the atria.

    Full Text Available Nowadays paroxysmal AV nodal reentrant tachycardia (AVNRT is one of the most widespread arrhythmias. In most cases AVRNT is a recurrent process, and it worsens the life quality of such patients, reduces their workability and increases the incidence of applying for medical help. Thus AVNRT today is of special attention among investigators. The interest of clinicians to the problem of cardiac arrhythmias is associated with permanent dissatisfaction with the results of antiarrhythmic therapy and also with the rapid development of the surgical methods of treatment, i.e. the use of radio frequency catheter ablation.

  1. An update on complications associated with transcatheter aortic valve implantation: stroke, paravalvular leak, atrioventricular block and perforation.

    Science.gov (United States)

    Chiam, Paul T L; Ewe, See Hooi

    2013-09-01

    Transcatheter aortic valve implantation (TAVI) has become an alternative therapeutic option for patients with symptomatic severe aortic stenosis at high surgical risk and the standard of care in patients who are inoperable for open aortic valve replacement. With technological evolution and increasing experience, the procedure has become more predictable. Complications of TAVI, however, are not infrequent, and can range from minor to life-threatening events. Stroke, paravalvular leak, various forms of atrioventricular block, including the need for permanent pacemakers and aortic annular and ventricular perforation will be the focus of the present review. Other complications associated with TAVI (such as vascular injury, acute kidney injury, coronary obstruction, valve malpositioning or migration) are clinically important, but are beyond the scope of this article. Understanding the occurrence and pathophysiology of these complications may provide insights into the improvement of the transcatheter devices and techniques, and aid in extending the application of TAVI to a broader population.

The procedure was successfully performed and the patient showed a remarkable improvement in clinical condition. Cardiogenic shock complicating right heart ventricle in elderly requires careful patient selection for invasive strategies that can sometimes rely on the willingness of the patient, as the procedural outcome appears to be poor in this high-risk population.

  7. Outcomes of AV Fistulas and AV Grafts after Interventional Stent-Graft Deployment in Haemodialysis Patients

    International Nuclear Information System (INIS)

    PurposeThe study was designed to assess outcomes of arteriovenous (AV) accesses after interventional stent-graft deployment in haemodialysis patients.Materials and Methods63 haemodialysis patients with 66 AV fistulas and AV grafts were treated by interventional stent-graft deployment from 2006 to 2012 at our hospital. Data of these patients were retrospectively analysed for location of deployed stent-grafts, occurrence and location of (re-)stenosis and (re-)thrombosis. Complex stenosis was the most frequent indication for stent-graft deployment (45.5 %), followed by complications of angioplasty with vessel rupture or dissection (31.8 %).ResultsA high rate of procedural success was achieved (98.5 %). The most frequent location of the deployed stent-graft was the draining vein (66.7 %). Stent-graft deployment was more frequent in AV grafts than in AV fistulas. Primary patency was 45.5 % at 6 month, 31.3 % at 12 month and 19.2 % at 24 month. Primary patency was significantly better for AV fistulas than for AV grafts with deployed stent-grafts. Patency of the deployed stent-graft was much better than overall AV access primary patency with deployed stent-graft. Re-stenosis with thrombosis was the most frequent indication for re-intervention. Most frequent location of re-stenosis was the draining vein (37.1 %), followed by stenosis at the AV access (29.5 %) and the deployed stent-graft (23.5 %).ConclusionRe-stenosis and re-thrombosis remain frequent in AV fistulas and AV grafts in haemodialysis patients despite stent-graft deployment. Re-stenosis of the deployed stent-graft is, only in the minority of the cases, responsible for AV access dysfunction

    2016-01-01

    Background: The sarcoplasmic reticulum Ca2+-ATPase (SERCA2) pump is an important component of the Ca2+-clock pacemaker mechanism that provides robustness and flexibility to sinus node pacemaking. We have developed transgenic mice with reduced cardiac SERCA2 abundance (Serca2 KO) as a model for investigating SERCA2's role in sinus node pacemaking. Methods and Results: In Serca2 KO mice, ventricular SERCA2a protein content measured by Western blotting was 75% (P clock with 2 μM ryanodine induced bradycardia that was less pronounced in Serca2 KO preparations (9 ± 1% vs. 20 ± 3% in Serca2 FF; P clock. Mathematical modeling was used to dissect the effects of membrane- and Ca2+-clock components on Serca2 KO mouse heart rate and sinus node action potential. Computer modeling predicted a slowing of heart rate with SERCA2 downregulation and the heart rate slowing was pronounced at >70% reduction in SERCA2 activity. Conclusions: Serca2 KO mice show a disrupted Ca2+-clock-dependent pacemaker mechanism contributing to impaired sinus node and atrioventricular node function.

  13. Indicators of a poor outcome after temporary pacing in patients with complete atrioventricular block

    International Nuclear Information System (INIS)

    Background: Temporary pace maker (tpm) implantation is an emergency procedure, performed in symptomatic patients with AV block We report our experience of temporary pacing at a tertiary care center. It is the first study of its type from a local center. Objectives: To study the clinical course of patients after tpm implantation and to determine indicators of a poor outcome after tpm implantation. Methods: This was descriptive retrospective study. Data of all tpm procedures performed at Children Hospital from 2006 to 2012 was retrieved. We excluded patients with surgically placed tpm leads. All patients receiving transvenous tpm were included in our study. Results: Total of 12 patients received tpm, 8 were male (66.6%) and 4 were female (33.3%). Median age was 6 years ( range 1.4 -13 year ). Mean weight was 30kg, (range 8.7 - 50kg). All of them presented with complete heart block.One patient each had post diphtheria cardiomyopathy, unknown poisoning. The rest had congenital heart block. The mean period between tpm to ppm implantation was 5 days, (range 1 - 30 days). One patient spontaneously reverted to sinus rhythm(8.3%), 6 had ppm implantation (58.3%), 5 patients expired (33.3%). A low Ejection Fraction was found to be associated with a poor outcome (p<0.01). Variables that were associated with a poor outcome(mortality), were SOB (p<0.015), weak pulses (p<0.015), and hepatomegaly (p<0.01). Conclusion: Low Ejection Fraction and Heart failure is associated with a poor outcome and increased mortality in patients with complete AV block. We suggest that pacing should be considered in patients earlier, before they develop signs or symptoms of cardiac dysfunction. (author)

  6. Left bundle branch block, atrioventricular block, torsade de pointes and long QT syndrome: is this too much for a rare cardiomyopathy?

    Science.gov (United States)

    Rodrigues, Bruno; Correia, Emanuel; Ferreira Santos, Luís; Moreira, Davide; Delgado, Anne; Gama, Pedro; Costa, António; Pipa, João; Santos, Oliveira

    2013-05-01

    Left ventricular noncompaction (LVNC) is now recognized as a distinct form of cardiomyopathy with a clinical presentation and natural history of its own. Common manifestations of LVNC include heart failure, ventricular arrhythmias and embolic events, but serious atrioventricular conduction disturbances are rarely reported in the literature. The authors describe the case of a 40-year-old woman who went to the emergency department due to syncope. The ECG revealed left bundle branch block (LBBB) and 2:1 atrioventricular block (AVB) and the patient was admitted for pacemaker implantation. During hospitalization she developed torsade de pointes and complete AVB with increased QTc. The echocardiogram showed images compatible with LVNC. This case provides additional evidence that LVNC may be complicated by 2:1 (or complete) AVB, intraventricular conduction disturbances (LBBB) and repolarization abnormalities (long QT). This combination of electrocardiographic changes has rarely been reported in the literature. We describe a series of affected patients, focusing on electrocardiographic characteristics.

    In considering a social network, there are cases where people is transferred to another place. Then the physical (direct) relations among nodes are lost by the movement. In terms of a network theory, some nodes break the present connections with neighboring nodes, move and there build new connections of nodes. For simplicity we here consider only that two nodes exchange the place each other on a network. Such exchange is assumed to be constantly carried out. We study this dynamic network (nod...

  10. Elective ilioingunial lymph node irradiation

    Energy Technology Data Exchange (ETDEWEB)

    Henderson, R.H.; Parsons, J.T.; Morgan, L.; Million, R.R.

    1984-06-01

    Most radiologists accept that modest doses of irradiation (4500-5000 rad/4 1/2-5 weeks) can control subclinical regional lymph node metastases from squamous cell carcinomas of the head and neck and adenocarcinomas of the breast. There have been few reports concerning elective irradiation of the ilioinguinal region. Between October 1964 and March 1980, 91 patients whose primary cancers placed the ilioinguinal lymph nodes at risk received elective irradiation at the University of Florida. Included are patients with cancers of the vulva, penis, urethra, anus and lower anal canal, and cervix or vaginal cancers that involved the distal one-third of the vagina. In 81 patients, both inguinal areas were clinically negative; in 10 patients, one inguinal area was positive and the other negative by clinical examination. The single significant complication was a bilateral femoral neck fracture. The inguinal areas of four patients developed mild to moderate fibrosis. One patient with moderate fibrosis had bilateral mild leg edema that was questionably related to irradiation. Complications were dose-related. The advantages and dis-advantages of elective ilioinguinal node irradiation versus elective inguinal lymph node dissection or no elective treatment are discussed.

  12. Lymph node imaging: Basic principles

    International Nuclear Information System (INIS)

    Lymph nodes are involved in a wide variety of diseases, particularly in cancer. In the latter, precise nodal staging is essential to guide therapeutic options and to determine prognosis. For long, imaging of the lymphatic system has been limited to lymph vessel,especially via the exclusive use of conventional lymphography, at the expense of invasive procedures and patient's discomfort. Three main technical advances, however, have recently completed the clinical armamentarium for lymph node imaging: first, the refinement of cross sectional imaging, i.e. CT and MRI, combined or not with dedicated contrast agents, has progressively replaced conventional lymphography in oncology situations; second, the development of intra-operative sentinel node mapping has profoundly modified the diagnostic and therapeutic procedures in several cancer situations, mostly melanoma and breast cancer; finally, the increased availability of functional imaging, especially through the use of FDG-PET, has greatly contributed to the accuracy improvement of nodal metastases identification. The aim of this review will thus be to briefly review the anatomy and physiology of the lymphatic systems and to overview the basic principles of up-to-date lymph node imaging

    2011-01-01

    Full Text Available Background. A prolonged coronary artery spasm with interruption of coronary blood flow can lead to myocardial necrosis and increase of cardiospecific enzymes and can be complicated with cardiac rhythm disturbances, syncopc, or even sudden cardiac death. Case report. A 55-year old male felt a severe retrosternal pain when exposing himself to cold weather. The pain lasted for 20 minutes and was followed by the loss of conscience. Electrocardiogram (ECG showed a complete antrioventricular (AV block with nodal rhythm and marked elevation of ST segment in inferior leads. Electrocardiogram was soon normalized, but serum activities of cardiospecific enzymes were increased. Coronarography showed normal findings for the left coronary artery and a narrowing at the middle part of the right coronary artery, which disappeared after intracoronary application of nitroglycerine. The following therapy was prescribed: Diltiazem, Amlodipin, Isosorbid mononitrate, Molisdomin, Atrovastatin, Aspirin and Nitroglycerine spray. After 7 months medicaments were abandoned and the patient experienced again reccurent chest pain episodes at rest. Transitory ST segment elevation was recorded in inferior leads of ECG, but without increase of cardiospecific enzymes serum activities. After restoration of the medicament therapy anginal episodes ceased. Conclusion. Coronary dilators in maximal doses can prevent attacks of vasospastic angina.

    2012-06-01

    Full Text Available Målet med artikkelen er å synliggjøre hvordan bachelorstudenter i ergoterapi kan utvikle profesjonell handlingskompetanse gjennom aktivitetsbasert pedagogikk. På bakgrunn av dette gjennomførte vi kvalitative fokusgruppeintervju med 12 ergoterapeutstudenter som hadde deltatt i undervisningsopplegget “Aktivitetsgrupper-lede og delta”. Datamaterialet ble analysert etter retningslinjer for fenomenologisk basert meningskondensering. Studentene diskuterte sine erfaringer og det kom tydelig fram at undervisningsopplegget ga dem muligheter til å bruke sitt engasjement og sin kreativitet i valg av aktiviteter for sin simulerte aktivitetsgruppe. Videre fikk de muligheter til å oppdage sider ved anvendelse av aktiviteter for ulike pasienter, som de ikke kunne forstå uten integrering av teori i praktisk ferdighetstrening. Ved planlegging, gjennomføring og refleksjon over å lede og delta i aktivitetsgrupper, oppøvet de evnen til handlingsrefleksjon. Aktivitetsbasert pedagogikk kan bidra til utvikling av profesjonell handlingskompetanse og det er behov for både teoretiske og praktiske læringsformer. Funnene ble diskutert i lys av pedagogisk handlingsteori.

  18. Sinus Node and Atrial Arrhythmias.

    John, Roy M; Kumar, Saurabh

    2016-05-10

    Although sinus node dysfunction (SND) and atrial arrhythmias frequently coexist and interact, the putative mechanism linking the 2 remain unclear. Although SND is accompanied by atrial myocardial structural changes in the right atrium, atrial fibrillation (AF) is a disease of variable interactions between left atrial triggers and substrate most commonly of left atrial origin. Significant advances have been made in our understanding of the genetic and pathophysiologic mechanism underlying the development and progression of SND and AF. Although some patients manifest SND as a result of electric remodeling induced by periods of AF, others develop progressive atrial structural remodeling that gives rise to both conditions together. The treatment strategy will thus vary according to the predominant disease phenotype. Although catheter ablation will benefit patients with predominantly AF and secondary SND, cardiac pacing may be the mainstay of therapy for patients with predominant fibrotic atrial cardiomyopathy. This contemporary review summarizes current knowledge on sinus node pathophysiology with the broader goal of yielding insights into the complex relationship between sinus node disease and atrial arrhythmias.

    2006-01-01

    Adaptive frame/field coding techniques have been adopted in many international video standards for interlaced sequence coding. When the frame/field adaptation is applied on the picture level, the coding efficiency is improved greatly,compared with the pure frame coding or the pure field coding. The picture-level adaptive frame/field coding (PAFF) selects frame coding or field coding once for one picture. If this frame/field adaptation is extended to Macro Block (MB) level, the coding efficiency will be further increased. In this paper, a novel MB-level adaptive frame/field (MBAFF) coding scheme is proposed. In the proposed MBAFF scheme, the top field of the current picture is used as a reference. The experiments are implemented on the platforms of Audio Video coding Standard (AVS) base profile and H.264/AVC, respectively. On the AVS platform, 0.35dB gain can be achieved averagely, compared with AVS1.0 anchor. On the H.264/AVC platform, 0.16dB gain can be achieved averagely, compared with MBAFF scheme of H.264/AVC. Additionally, an extensive subjective quality enhancement can be achieved by the proposed scheme.

    【Objective】 To explore the significance of electrocard iogram monitoring during the effective application of radiofrequency energy to s low atrioventricular (AV) nodal pathway ablation. 【Methods】 Slow AV nodal pathway ablation was performed in 58 patients with slownfast AV nodal ree-trant tachyca rdi a (AVNRT). The changes of electrocardiogram were monitored during the effective application of low radiofrequency RF energy (15~25 W). A faster rate of junctio nal ectopy (>150 min-1), ventriculoatrial (VA) block in association with j unctional ectopy, and l ong P-R interval during sinus beat were considered as harbingers of atrioventri cular (AV) block. RF energy deliveries were discontinued as soon as the harbinge rs of AV block occurred. Otherwise, RF energy continued until junctional ectopie s were decreased or vanished. If junctionnal ectopies were not decreased, RF ene rgy continued lasted for 90~120 s. 【Results】 Slow AV nodal pathway ablation w as successful in all patients who had junctional ectopy during the effective del ivery of RF energy. The effective ablation time was (128±26) s. 54 patients exp erienced one time successful ablation, and 4 patients experienced two times abla tion. Unsustained AV block occurred in 6 patinets after RF energy deliveries whi ch were immediately terminated because of VA block in association with junctiona l ectopy in 4 patinets and long P-R interval during sinus beats in 2 patients. No patients developed permanent AV block. Recurrent AVNRT requiring second ablat ion occurred in 2 of 58 successfully ablated slow pathway during (18±16) months of follow-up. 【Conclusion】 RF energy deliveries could be instructed b y intracardiac electrocardiogram monitoring during AVNRT ablation, which could e nhance the successful rate of slow pathway ablation, reduce recurrence and avoide permanent AV block.%【目的】 探讨房室结慢径路消融有效放电过程心电监测的意 义。【方法】 58例慢-快型房

    Full Text Available  SAMMENDRAGI perioden 1999-2001 vil det bli gjennomført tre kostholdsundersøkelser som til sammen skal kartlegge konsum avmatvarer med betydning for inntaket av miljøgifter i Norge, fortrinnsvis kadmium, kvikksølv, PCB og dioksiner.Disse giftene finnes hovedsakelig i krabbe, flatfisk, skjell, gjedde og abbor, lever eller nyre fra vilt og viltvoksendesopp. Fordi gjennomsnittskonsumet er lavt, spørres det ikke spesifikt om disse matvarene i landsdekkende kostholdsundersøkelsersom 'Norkost'. Hensikten med studien er å kunne gi en bedre beskrivelse av eksponeringsfordelingeni befolkningen med tanke på miljøgifter. Fordelingen er antakelig skjev, dvs. et stort antall personerventes å ha et lavt inntak og noen få personer ventes å ha et relativt høyt inntak av de undersøkte stoffene. Eventuelleukjente risikogrupper vil kunne avdekkes, og det er av stor interesse å undersøke hvor stor eksponeringen i deutsatte gruppene er.Del A av undersøkelsen er landsdekkende og omfatter en postal frekvensundersøkelse til 10 000 tilfeldig valgtepersoner mellom 18 og 79 år. Del B omfatter en postal frekvensundersøkelse til 6000 tilfeldig valgte personer i sekskommuner, der tre er kystkommuner og tre er innlandskommuner. Kommunene blir valgt ut fra kjennskap til godtilgang på de aktuelle matvarene. Vi antar at der tilgangen på matvarene er god, er konsumet høyere. Del C avundersøkelsen vil omfatte høykonsumenter av aktuelle matvarer, valgt fra del B av undersøkelsen. Dette vil være endybdestudie der analyser av miljøgifter i blod, hår og urin også skal inngå.Undersøkelsen er den første i sitt slag her til lands og vi kjenner ikke til at tilsvarende studier er gjort i andreland. Hensikten med artikkelen er å gi en beskrivelse av undersøkelsen i en tidlig fase av gjennomføringen.Meltzer HM, Bergsten C, Stene LC, Stigum H, Wiborg ML, Lund-Larsen K, Alexander J. Consumption ofcontaminated foods – Description of a dietary survey

    Active-targeted delivery to lymph nodes represents a major advance toward more effective treatment of immune-mediated disease. The MECA79 antibody recognizes peripheral node addressin molecules expressed by high endothelial venules of lymph nodes. By mimicking lymphocyte trafficking to the lymph nodes, we have engineered MECA79-coated microparticles containing an immunosuppressive medication, tacrolimus. Following intravenous administration, MECA79-bearing particles showed marked accumulation in the draining lymph nodes of transplanted animals. Using an allograft heart transplant model, we show that targeted lymph node delivery of microparticles containing tacrolimus can prolong heart allograft survival with negligible changes in tacrolimus serum level. Using MECA79 conjugation, we have demonstrated targeted delivery of tacrolimus to the lymph nodes following systemic administration, with the capacity for immune modulation in vivo. PMID:27134176

MATERIAL AND....... RESULTS: Eleven (28%) patients were upstaged. The sentinel lymph node identification rate was 97.5%. Sentinel lymph node biopsy significantly differentiated between patients with or without lymph node metastasis (P = 0.001). Lymphatic mapping revealed 124 hotspots and 144 hot lymph nodes were removed by...... sentinel lymph node biopsy. Three patients developed a lymph node recurrence close to the primary tumor site during follow-up. Added oblique lymphoscintigraphic images and/or tomography revealed extra hotspots in 15/40 (38%) patients. In 4/40 (10%), extra contralateral hotspots were detected. CONCLUSION...

  10. Targeted Delivery of Immunomodulators to Lymph Nodes

    Full Text Available Active-targeted delivery to lymph nodes represents a major advance toward more effective treatment of immune-mediated disease. The MECA79 antibody recognizes peripheral node addressin molecules expressed by high endothelial venules of lymph nodes. By mimicking lymphocyte trafficking to the lymph nodes, we have engineered MECA79-coated microparticles containing an immunosuppressive medication, tacrolimus. Following intravenous administration, MECA79-bearing particles showed marked accumulation in the draining lymph nodes of transplanted animals. Using an allograft heart transplant model, we show that targeted lymph node delivery of microparticles containing tacrolimus can prolong heart allograft survival with negligible changes in tacrolimus serum level. Using MECA79 conjugation, we have demonstrated targeted delivery of tacrolimus to the lymph nodes following systemic administration, with the capacity for immune modulation in vivo.

    A method and system for job backfill scheduling dedicated heterogeneous nodes in a multi-node computing environment. Heterogeneous nodes are grouped into homogeneous node sub-pools. For each sub-pool, a free node schedule (FNS) is created so that the number of to chart the free nodes over time. For each prioritized job, using the FNS of sub-pools having nodes useable by a particular job, to determine the earliest time range (ETR) capable of running the job. Once determined for a particular job, scheduling the job to run in that ETR. If the ETR determined for a lower priority job (LPJ) has a start time earlier than a higher priority job (HPJ), then the LPJ is scheduled in that ETR if it would not disturb the anticipated start times of any HPJ previously scheduled for a future time. Thus, efficient utilization and throughput of such computing environments may be increased by utilizing resources otherwise remaining idle.

    In clinical practice, the combination of congenital heart disease (CHD) with malformations of other organs occurs in about 10 % of cases, including chromosomal disease with heart defects, which are observed mainly with certain syndromes. In the Bakoulev SCCS (Moscow, Russian Federation), from 01.2005 to 01.2011, complete atrioventricular septal defect (CAVSD) repair was performed on 163 patients (5.6 ± 3.0 months) with Down Syndrome (DS) using the single-patch (n = 40) and the two-patch (n = 123) methods. The control group consisted of 214 infants aged 6.49 ± 3.03 months with CAVSD and normal karyotype. A retrospective cohort study was made, as well as a comparative analysis of the immediate (up to 30 days) and long-term (12-75 months, at the average of 56 ± 15) results of the repair of CAVSD in infants with DSand normal karyotype/chromosome set (NK). During the hospital treatment period, we registered the following complications: pulmonary hypertensive crises in 6 % (n = 9) of patients with DS and in 10 % (n = 21) of infants with NK, infectious complications in 21% (n = 34) of patients with DS and in 8% (n = 17) of infants with NK. Squeal structures in groups were differentiated. The doses and duration of cardiotonic support in the NK patients were significantly higher in comparison with the DS patients (7.5 ± 2.1 days vs 3.4 ± 1.15 days, p Down syndrome. Concerning the long-term results, there was no significant difference (Gehan-Wilcoxon test) in actuarial freedom from reoperation after repair of CAVSD between DS and NK groups (p Down Syndrome in patients significantly increases the risk of severe co-morbidities that have a significant impact on the recovery period, as well as on life expectancy even after successful CHD correction.

    Full Text Available Medisinsk forskning har ført til store framskritt de siste tiårene. Det er investert mye mer ressurser på basalforskning og klinisk forskning enn på å utvikle og evaluere metoder for å sikre at pasientene får nytte av forskningen. Formålet med implementeringsforskning er å redusere gapet mellom forskning og praksis, ved å utvikle og evaluere tiltak som kan sikre at behandlingen som pasientene mottar er kunnskapsbasert, at den er omsorgsfull og av god kvalitet.I denne artikkelen gjør vi rede for hva implementering og implementeringsforskning er. Vi belyser historikken til denne unge vitenskapen, og illustrerer mangfoldet i de faglige tilnærmingene og begrepene som brukes om det å få forskning brukt i praksis. Det finnes en rekke teorier om endring av atferd, både på individnivå og på organisatorisk nivå. Teoriene er imidlertid i liten grad testet empirisk, særlig når det gjelder å endre atferd i helsetjenesten.Systematiske oversikter over metodisk gode studier er den beste kilden til informasjon om effekt av implementeringstiltak. The Cochrane Effective Practice and Organisation of Care Group (EPOC er en viktig kilde for slike oversikter. De systematiske oversiktene som er utarbeidet på dette feltet viser at passive dissemineringstiltak har begrenset effekt, mens mer aktive tiltak kan ha liten til moderat effekt. Det er ofte betydelig variasjon i effekt på tvers av studiene. Det er derfor viktig å få bedre kunnskap om hvilke faktorer som kan forklare slike forskjeller i effekt.Vi gir eksempler på norske implementeringsstudier, og refererer bidrag fra forskere ved Kunnskapssenteret.

  13. Evaluation of sentinel lymph node biopsy in clinically node-negative breast cancer

    International Nuclear Information System (INIS)

    In patients with clinically node-negative breast cancer, diagnosed with palpation and several types of imaging examination, sentinel lymph nodes accurately predict the status of the other axillary nodes, which determine the nature of subsequent adjuvant treatment. In addition, compared with axillary lymph node dissection, sentinel-node biopsy results in less postoperative morbidity, including pain, numbness, swelling, and reduced mobility in the ipsilateral arm. We analyzed the validity of the sentinel node biopsy procedure using dual-agent injection of blue dye and radioactive colloid performed in our hospital from May 2006 through March 2010. A total of 258 breasts of 253 patients were studied. Simultaneous axillary lymph node dissection was performed only if rapid intraoperative diagnosis identified metastasis in sentinel lymph nodes. The identification rate, accuracy, provisional false-negative rate, which was calculated with data from all 65 patients whose sentinel lymph nodes had metastasis, and axillary recurrence rate of sentinel node biopsy were calculated. The sentinel node identification rate was 99.2%, and the accuracy of sentinel lymph node status was 98.0%. The provisional false-negative rate was 7.7%. During an observation period averaging 24 months, axillary recurrence was observed in only 1 of 256 cases (0.4%), and there were no cases of parasternal recurrence. In patients who underwent sentinel-node biopsy without axillary lymph node dissection, there was no obvious morbidity. Our sentinel-node biopsy procedure yielded satisfactory results, which were not inferior to the results of previous clinical trials. Thus, we conclude our sentinel-node biopsy procedure is feasible. If the efficacy and safety of sentinel-node biopsy are confirmed in several large-scale randomized controlled trials in Europe and the United States, sentinel-node biopsy will become a standard surgical technique in the management of clinically node-negative breast cancer

  14. Sentinel node localization in breast carcinoma

    International Nuclear Information System (INIS)

    Objective: To determine the success rate of sentinel node dissection and the sensitivity of sentinel node to determine the presence of axillary node metastasis in women with clinically node negative breast cancer. Patients and Methods: A total of 15 patients of early carcinoma breast were recruited in the study. Five patients were injected with radiocolloid and later with isosulfan blue in the subareolar region. Ten patients were given isosulfan blue only. All the patients were subjected to standard axillary clearance after sentinel node biopsy through separate incisions. Sentinel node was examined by intra-operative frozen section and all of the dissected lymph nodes were examined histopathologically for tumour deposits. Results: Sentinel lymph node was successfully excised in all the cases 15/15 (100%). In 14 of the patients the sentinel node pathology was truly predictive of axillary nodal status. Sensitivity of the test was 93.33% and the positive predictive value was 100%. Conclusion: Sentinel node biopsy should be followed by standard axillary lymph adenectomy until the results of multiple prospective randomized trials define the role of this technique in the management of carcinoma breast.

    We present a network model in which words over a specific alphabet, called structures, are associated to each node and undirected edges are added depending on some distance measure between different structures. This model shifts the underlying principle of network generation from a purely mathematical one to an information-based one. It is shown how this model differs from the Barábasi-Albert and duplication models and how it can generate networks with topological features similar to biological networks: power law degree distribution, low average path length, clustering coefficient independent from the network size, etc. Two biological networks: S. cerevisiae gene network and E. coli protein-protein interaction network, are replicated using this model.

    2005-01-01

    In considering a social network, there are cases where people is transferred to another place. Then the physical (direct) relations among nodes are lost by the movement. In terms of a network theory, some nodes break the present connections with neighboring nodes, move and there build new connections of nodes. For simplicity we here consider only that two nodes exchange the place each other on a network. Such exchange is assumed to be constantly carried out. We study this dynamic network (node exchange network NEN) and uncover some new features which usual networks do not contain. We mainly consider average path length and the diameter. Lastly we consider a propagation of one virus on the network by a computer simulation. They are compared to other networks investigated hitherto. The relation to a scale free network is also discussed.

    Att i förväg försöka förutsäga vilket lag som kommer vinna i en fotbollsmatch har nog de flesta försökt sig på någon gång. Att gissa och att faktiskt försöka att analysera båda lagens förutsättningar är två väldigt olika metoder att komma fram till sitt resultat. I och med att datorkraften de senaste åren kraftigt förbättrats har det också kommit fler och framför allt tyngre matematiska modeller för att skatta utfallet av matcher. I detta examensarbete används Pi-ratingsystemet som går ut på ...

    2011-01-01

    In this paper, we discuss the hardware development of a UWB sensor node for wireless body area networks. A few unique UWB pulse generation techniques have been discussed. The sensor node transmits multiple pulses per bit to increase the average power of the transmitted signal in order to improve the bit-error rate (BER) performance. The multiple-pulse per bit technique is also used as the coding scheme to identify the individual sensor nodes when more than one sensor forms a network. The sensors nodes are able to transmit body signals up to 2 m with a BER lower than 10(-5). PMID:22254770

    Background Atrioventricular nodal reentrant tachycardia (AVNRT) is one of the most common paroxysmal supraventricular tachyarrhythmias.The aim of the study was to prospectively compare the characteristics of radiofrequency catheter ablation of AVNRT guided by a magnetic navigation system with the conventional procedure.Methods Patients with AVNRT diagnosed by electrophysiological tests were randomized into two groups.In the conventional technique group (CMT),a common 4-mm-tip quadrapolar temperature-controlled ablation catheter was used. In the magnetic navigation system guidance group (MNS), a magnetic 4-mm-tip quadrapolar temperature-controlled ablation catheter was used.The following parameters were collected and compared between the two groups: ablation procedure time,patient fluoroscopy time,operator fluoroscopy time,energy delivery numbers,maximal energy per deployment,success rate,complication rate and operative cost.Results Forty patients were enrolled and randomized into CMT and MNS groups.The age,gender,tachycardia history and basic cardiovascular diseases of the two groups were comparable (P >0.05).All procedures were conducted successfully without complications.No tachycardia recurred during the follow-up period of (9.3±2.6) months.In the MNS group,the patient and operator fluoroscopy times ((11.5±4.3) min,(4.2±1.5) min),energy delivery numbers (3.2±0.9),and maximal energy per deployment ((16.9±3.4) W) were shorter or lower than those of the CMT group ((14.3±6.2) min,(13.6±3.5) min,6.3±2.1,(23.7±1.3) W,respectively) (P <0.05).But the operative cost for the MNS group was higher than that of the CMT group (P <0.01 ).Conclusion Magnetic navigation system guided radiofrequency catheter ablation of AVNRT has the advantages of shorter fluoroscopy time and lower energy delivery numbers and maximal energy per deployment compared to the present conventional ablation technique.

    2012-01-01

    Following the success of the audio video standard (AVS) for 2D video coding, in 2008, the China AVS workgroup started developing 3D video (3DV) coding techniques. In this paper, we discuss the background, technical features, and applications of AVS 3DV coding technology. We introduce two core techniques used in AVS 3DV coding: inter-view prediction and enhanced stereo packing coding. We elaborate on these techniques, which are used in the AVS real-time 3DV encoder. An application of the AVS 3DV coding system is presented to show the great practical value of this system. Simulation results show that the advanced techniques used in AVS 3DV coding provide remarkable coding gain compared with techniques used in a simulcast scheme.

    Background: Previous studies of CT enhancement of lymphomatous lymph nodes (LLN) of the neck and the mediastinum showed that the LLN had lower enhancement values than normal lymph nodes. Purpose: To elucidate the contrast medium enhancement curves of LLN in the retroperitoneum by comparing the curves of LLN with those of normal lymph nodes, to test whether differences between these curves could be of diagnostic value, and to compare the present enhancement curves of LLN of the retroperitoneum with the curves of LLN of the neck and the mediastinum from previous similar investigations. Material and Methods: Twenty-eight consecutive patients with LLN of the retroperitoneum (three with Hodgkin's lymphoma [HL]) and 21 control patients with sarcomas and thus presumably normal retroperitoneal nodes underwent dynamic CT examinations. The previous, similar investigation of lymph nodes of the neck comprised 28 patients with LLN and the investigation of mediastinal lymph nodes comprised 24 patients with LLN. Results: The enhancement curves of the retroperitoneal LLN had significantly lower attenuation than those of the retroperitoneal control nodes. A combination of peak contrast value and time to peak adjusted to total body weight yielded a diagnostic accuracy which at the best showed a sensitivity of 90.5% with a specificity of 82.6%. The LLN of the retroperitoneum had higher attenuation values than corresponding nodes of the mediastinum but no significant difference was found between LLN of the retroperitoneum and LLN of the neck in previous similar investigations. Conclusion: The comparison of enhancement curves of retroperitoneal LLN with retroperitoneal control nodes showed a marked similarity with and substantiates our previous findings in lymph nodes of the neck and of the mediastinum. The best diagnostic accuracy was achieved by combining the parameters peak contrast value and time to peak and adjusting these values to the body weight. Peak enhancement of the

    Oppgaven handler om Rawls "theory of justice". Jeg har lagt vekt på teorien som en verdinøytral prosedyre. Jeg kritiserer ulikhetsprinsippet for at det tillater forskjeller som er så store at de underminerer verdien av de politiske frihetene. Videre viser jeg hvordan mennesker er avhengige av å bekreftes gjennom gjensidige relasjoner av anerkjennelse. Rawls begrep om selvrespekt er utilstrekkelig og han kan derfor ikke sikre borgernes autonomi.

    2009-09-01

    Full Text Available En gjennomgang av spontanrapportene fra den norske bivirkningsdatabasen viser en betydelig geografisk variasjon når det gjelder innrapportering av bivirkninger. I Norge blir disse meldingene evaluert ved RELIS (Regionale legemiddelinformasjonssentre av tverrfaglige team bestående av leger og farmasøyter. Bivirkningsarbeidet ved RELIS gjøres på oppdrag fra Statens legemiddelverk, som har det overordnede ansvar for legemiddelovervåkningen i Norge. Vurderingene baseres på kjent risikoprofil for mistenkte legemidler, indikasjon, dosering, tidsmessig sammenheng mellom reaksjon og medikamentinntak, effekt av seponering og eventuelle andre risikofaktorer. 3345 legemiddel/bivirkningskombinasjoner ble vurdert på bakgrunn av 1408 rapporter i 2006. De fleste mistenkte bivirkningene ble klassifisert som mulige, ettersom andre faktorer også kunne ha spilt en rolle. Få bivirkninger ble klassifisert som sikre. Informasjon om bivirkninger i litteratur og databaser er i flere tilfeller preget av manglende homogenitet, tilfeldige sammentreff i tid, manglende data og lite vurdering av sammenhengen mellom reaksjonen og medisinbruken. Kliniske studier har begrenset mulighet til å påvise annet enn de vanligste bivirkningene. Det kan ta år etter markedsføring å fastslå sammenhengen med mer sjeldne bivirkninger. Frekvenstabeller for bivirkninger er anslag basert på et begrenset antall pasienter, spesielt for nye legemidler. Evaluering av bivirkningsrapporter fra helsepersonell kan avdekke mangel på lett tilgjengelig informasjon og bidra til ny kunnskap om et legemiddels bivirkningsprofil

  8. Classification between Failed Nodes and Left Nodes in Mobile Asset Tracking Systems †

    Directory of Open Access Journals (Sweden)

    Kwangsoo Kim

    2016-02-01

    Full Text Available Medical asset tracking systems track a medical device with a mobile node and determine its status as either in or out, because it can leave a monitoring area. Due to a failed node, this system may decide that a mobile asset is outside the area, even though it is within the area. In this paper, an efficient classification method is proposed to separate mobile nodes disconnected from a wireless sensor network between nodes with faults and a node that actually has left the monitoring region. The proposed scheme uses two trends extracted from the neighboring nodes of a disconnected mobile node. First is the trend in a series of the neighbor counts; the second is that of the ratios of the boundary nodes included in the neighbors. Based on such trends, the proposed method separates failed nodes from mobile nodes that are disconnected from a wireless sensor network without failures. The proposed method is evaluated using both real data generated from a medical asset tracking system and also using simulations with the network simulator (ns-2. The experimental results show that the proposed method correctly differentiates between failed nodes and nodes that are no longer in the monitoring region, including the cases that the conventional methods fail to detect.

    Full Text Available This paper presents design and development of intelligent sensor node for environmental monitoring. The node is equipped with multimode sensors for sensing different environmental parameters, the node can sense four different environmental parameters, light, temperature, humidity, and three different types of gases. The node has half duplex wireless communication feature which is achieved by using an IEEE 802.15.4 standard compliant transceiver. Here we have deployedvarious intelligent protocols to achieve intelligent power management and precision sensing. The node comes with various error detection and correction capability which enhanced the performance of the node. Two different types of methodology are used to prove the intelligence of the node. The node is equipped with multiple sensors like gas, temperature, and humidity, light. A Special remote system enables user to wirelessly select the particular sensor which provides high wireless hardware flexibility. More priority is given to power consumption and sensing efficiency which is achieved by incorporating various smart tasking and power management protocol. All sensed dataare digitized and processed by the internal analog to digital converter (ADC of a Programmable interface controller (PIC microcontroller and wirelessly transmitted to the base station fordata acquisition and statistical analysis.

    Fay, R.; Bland, J.

    2014-06-01

    A key aspect of ensuring optimum cluster reliability and productivity lies in keeping worker nodes in a healthy state. Testnodes is a lightweight node testing solution developed at Liverpool. While Nagios has been used locally for general monitoring of hosts and services, Testnodes is optimised to answer one question: is there any reason this node should not be accepting jobs? This tight focus enables Testnodes to inspect nodes frequently with minimal impact and provide a comprehensive and easily extended check with each inspection. On the server side, Testnodes, implemented in python, interoperates with the Torque batch server to control the nodes production status. Testnodes remotely and in parallel executes client-side test scripts and processes the return codes and output, adjusting the node's online/offline status accordingly to preserve the integrity of the overall batch system. Testnodes reports via log, email and Nagios, allowing a quick overview of node status to be reviewed and specific node issues to be identified and resolved quickly. This presentation will cover testnodes design and implementation, together with the results of its use in production at Liverpool, and future development plans.

    Understanding and controlling spreading processes in networks is an important topic with many diverse applications, including information dissemination, disease propagation and viral marketing. It is of crucial importance to identify which entities act as influential spreaders that can propagate information to a large portion of the network, in order to ensure efficient information diffusion, optimize available resources or even control the spreading. In this work, we capitalize on the properties of the K-truss decomposition, a triangle-based extension of the core decomposition of graphs, to locate individual influential nodes. Our analysis on real networks indicates that the nodes belonging to the maximal K-truss subgraph show better spreading behavior compared to previously used importance criteria, including node degree and k-core index, leading to faster and wider epidemic spreading. We further show that nodes belonging to such dense subgraphs, dominate the small set of nodes that achieve the optimal spreading in the network.

    1995-01-01

    In dogs, lymph drains from tissues throughout the head, including the tonsils, along lymphatic vessels to the facial, parotid, lateral retropharyngeal and mandibular lymph nodes. From the mandibular lymph nodes, lymph may flow to the ipsilateral medial retropharyngeal lymph nodes, or along anastomotic connections to the contralateral node. Afferent lymphatics convey lymph from these nodes to defined areas in the medial retropharyngeal nodes. They divide over the surface of the node, and withi...

  20. Sentinel lymph node biopsy: clinical relevance

    International Nuclear Information System (INIS)

    Sentinel lymph node biopsy (SLNB) has become an important technique in the management of patients with intermediate level melanoma, clinical operable breast cancer and some other cancers. The technique relies on lymphatic mapping to define the lymph drainage from a primary tumour with the premise that the lymph nodes, which directly drain from that area, will reflect the tumour status of the remainder of the node field. Current techniques use lymphoscintigraphy where a radioactive labelled particle and / or blue dye are injected intradermally or intraparenchymally to map the lymph drainage, often in conjunction with a radioactive gamma probe at surgery. In patients with melanoma the SLNB has improved the staging and prognostic information by more accurate determination of whether regional lymph nodes have metastatic spread. This has a major impact on patient management as those patients with negative nodes do not require regional lymph node dissection and have a significantly better prognosis. In our experience of over 3000 patients the combined sentinel node biopsy technique localised accurately 98% of sentinel lymph nodes. Lymphoscintigraphy in patients with melanoma to locate the sentinel lymph nodes involves the intradermal injection of a radiocolloid around the melanoma site or the excision biopsy site. Injections of 5 -10 MBq in 0.05-0.1ml/inj are used and typically 4 injections are usually required. Following tracer injection dynamic imaging is performed to follow the lymphatic collecting vessels until they reach the draining sentinel nodes. An image should be acquired as the vessels reach the node field so that the sentinel nodes directly receiving the channels can be identified and distinguished from any second tier nodes which may sometimes be seen. Delayed scans are performed 2 hours later at which time all regions which can possible drain the primary melanoma site are examined with 5-10 minute static images. The surface location of all sentinel nodes is

    2015-11-01

    We describe a case of a pigmented cervical lymph node mimicking the sentinel node during sentinel lymph node biopsy (SLNB) on a patient with oral squamous cell carcinoma (OSCC). The patient had extensive tattoos on his neck. This pigmented lymph node was not identified to be the sentinel lymph node using static and dynamic lymphoscintigraphy. Subsequent histological analysis revealed tattoo pigment within this lymph node. It is important during cervical SLNB to be aware that cutaneous tattoos can pigment lymph nodes. PMID:26188933

  5. Parallel node placement method by bubble simulation

    Science.gov (United States)

    Nie, Yufeng; Zhang, Weiwei; Qi, Nan; Li, Yiqiang

    2014-03-01

    An efficient Parallel Node Placement method by Bubble Simulation (PNPBS), employing METIS-based domain decomposition (DD) for an arbitrary number of processors is introduced. In accordance with the desired nodal density and Newton’s Second Law of Motion, automatic generation of node sets by bubble simulation has been demonstrated in previous work. Since the interaction force between nodes is short-range, for two distant nodes, their positions and velocities can be updated simultaneously and independently during dynamic simulation, which indicates the inherent property of parallelism, it is quite suitable for parallel computing. In this PNPBS method, the METIS-based DD scheme has been investigated for uniform and non-uniform node sets, and dynamic load balancing is obtained by evenly distributing work among the processors. For the nodes near the common interface of two neighboring subdomains, there is no need for special treatment after dynamic simulation. These nodes have good geometrical properties and a smooth density distribution which is desirable in the numerical solution of partial differential equations (PDEs). The results of numerical examples show that quasi linear speedup in the number of processors and high efficiency are achieved.

    2016-01-01

    The second generation Audio Video Coding Standard (AVS2) is the most recent video coding standard. By introducing several new coding techniques, AVS2 can provide more efficient compression for scene videos such as surveillance videos, conference videos, etc. Due to the limited scenes, scene videos have great redundancy especially in background region. The new scene video coding techniques applied in AVS2 mainly focus on reducing redundancy in order to achieve higher compression. This paper introduces several important AVS2 scene video coding techniques. Experimental results show that with scene video coding tools, AVS2 can save nearly 40%BD⁃rate (Bjøntegaard⁃Delta bit⁃rate) on scene videos.

    Klemm, Konstantin

    2013-01-01

    Social networks are discrete systems with a large amount of heterogeneity among nodes (individuals). Measures of centrality aim at a quantification of nodes' importance for structure and function. Here we ask to which extent the most central nodes can be found by purely local search. We find that many networks have close-to-optimal searchability under eigenvector centrality, outperforming searches for degree and betweenness. Searchability of the strongest spreaders in epidemic dynamics tends to be substantially larger for supercritical than for subcritical spreading.

    According to an aspect, a method for checkpointing in a hybrid computing node includes executing a task in a processing accelerator of the hybrid computing node. A checkpoint is created in a local memory of the processing accelerator. The checkpoint includes state data to restart execution of the task in the processing accelerator upon a restart operation. Execution of the task is resumed in the processing accelerator after creating the checkpoint. The state data of the checkpoint are transferred from the processing accelerator to a main processor of the hybrid computing node while the processing accelerator is executing the task.

    Full Text Available Abstract Introduction Primary cardiac lymphoma is rare. Case Presentation We report the case of a 64-year-old non-immunodeficient Caucasian man, with cardiac tamponade and paroxysmal third-degree atrioventricular block. Echocardiography revealed the presence of a large pericardial effusion with signs of tamponade and a right ventricular mass was suspected. Scanner investigations clarified the sites, extension and anatomic details of myocardial and pericardial infiltration. Surgical resection was performed due to the rapid impairment of his cardiac function. Analysis of the pericardial fluid and histology confirmed the diagnosis of non-Hodgkin large B-cell lymphoma. He was treated with chemotherapy. Conclusion The prognosis remains poor for this type of tumor due to delays in diagnosis and the importance of the site of disease.

    International Nuclear Information System (INIS)

    The Schmorl node represents displacement of intervertebral disc tissue into the vertebral body. Both Schmorl nodes and degenerative disc disease are common in the human spine. We performed a retrospective study, for the period from January 2003 to February 2005, evaluating 23 patients affected by painful Schmorl nodes, who underwent in our department percutaneous transpedicular injection of polymethylmethacrylate (vertebroplasty) in order to solve their back pain not responsive to medical and physical management. Eighteen patients reported improvement of the back pain and no one reported a worsening of symptoms. Improvement was swift and persistent in reducing symptoms. Painful Schmorl nodes, refractory to medical or physical therapy, should be considered as a new indication within those vertebral lesions adequately treatable utilizing Vertebroplasty procedure

    Full Text Available Metastasization and distinction from mammary carcinoma is of great clinical importance because of different treatment modalities. Here, we discuss a case of stage IIIC ovarian serous carcinoma, presenting with bilateral axillary nodes metastasis after 25 months interval of its initial presentation. Increased serum CA-125 level caused clinical suspicion. Computed tomography scan of abdomen and pelvis showed no residual disease or any abdominal lymphadenopathy. Mammography of both breast were normal. Bilateral axillary nodes were noted. Guided fine needle aspiration cytology (FNAC and biopsy of ovarian carcinoma to axillary node is a rare event. Its recogn done. Cytomorphology revealed poorly differentiated carcinoma, compatible to that of primary ovarian tumor. Thus, metastatic carcinoma to axillary node from ovary was confirmed. This case illustrates a rare metastatic presentation of ovarian carcinoma and unequivocal role of FNAC to provide rapid diagnosis and preferred to be first line diagnostic procedure.

  16. An Investigation into Node Strength Connectivity Correlation

    Institute of Scientific and Technical Information of China (English)

    SHI Jian-Jun; WANG Yong-Li; HE Da-Ren

    2009-01-01

    We propose investigating the node strength connectivity correlation by a resource-allocation method and the traditional multiple edge method, respectively. A rough analysis suggests that the resource-allocation node strength connectivity correlation is always negative, which is different from the connectivity correlation of the traditional multiple edge node strength (it can show either positive, negative or no correlation). As examples,empirical investigation results for two real world cooperation-competition networks (the 2004 Athens Olympic Games network and the mixed drink network) are presented. We believe that the resource-allocation node strength connectivity correlation can serve as a description of the relative crackajack distribution, which is a complementarity of the traditional multiple edge one.

  1. Node Disjoint Multipath Routing Considering Link and Node Stability protocol: A characteristic Evaluation

    CERN Document Server

    Upadhayaya, Shuchita

    2010-01-01

    Mobile Ad hoc Networks are highly dynamic networks. Quality of Service (QoS) routing in such networks is usually limited by the network breakage due to either node mobility or energy depletion of the mobile nodes. Also, to fulfill certain quality parameters, presence of multiple node-disjoint paths becomes essential. Such paths aid in the optimal traffic distribution and reliability in case of path breakages. Thus, to cater various challenges in QoS routing in Mobile Add hoc Networks, a Node Disjoint Multipath Routing Considering Link and Node Stability (NDMLNR) protocol has been proposed by the authors. The metric used to select the paths takes into account the stability of the nodes and the corresponding links. This paper studies various challenges in the QoS routing and presents the characteristic evaluation of NDMLNR w.r.t various existing protocols in this area.

    failed, linear lesions at the base of Koch' s triangle was then done. Results After ablation, AVNRT was non-inducible in all 37 patients without any complication except one case experienced transient first degree AV block. Focal ablation was performed in 34 patients, and linear ablation strategy was used in the remaining three cases to achieve the end point. Among all the 37 patients, slow pathway ablation was achieved in 14, whereas slow pathway modification was reached in the remaining 23 cases.The mean procedural time, the RF deliveries, the duration of RF application were ( 120 ± 32) min, (2. 9 ± 1.6)times, ( 130 ± 33 )s,respectively. The total fluoroscopy time and the physician X-ray exposure time were(5.3 ±2. 7)min and(2.9 ± 1.1 ) min,respectively. There was no significant change of the AH interval,the HV interval,and the atrioventricular nodal conduction refractory period after ablation. Compared with the first 18 patients, the mean procedural time, the total fluoroscopy time and the X-ray fluoroscopy time during magnetic navigation were significantly decreased in the later 19 patients (P <0. 001 ). It indicated that the learning curve of remote catheter ablation using the MNS is short. Conclusion Remote catheter ablation using the MNS to cure AVNRT is safe and effective with short learning curve and decreasing X-ray exposure time for interventional physicians.

  20. Radiation protection in sentinel node technique

    International Nuclear Information System (INIS)

    According to the sequential dissemination hypothesis, there's lymph node (named sentinel node) which is the first receiving cancer cells metastasizing from a primary tumor. Further, others nodes sequentially located might be affected. Surgical performance for several types of cancel includes the complete removal of the tumor and a complete local lymph node dissection (LND). Removing and analyzing the named sentinel node may avoid the complete LND. To locate the sentinel nod, it's usual the local administration of a radiopharmaceutical Tc-99m sulfur colloid several hours prior to surgery, and using an intraoperative gamma probe very sensitive to the gamma radiation. Although the activity is injected by the Nuclear Medicine staff, and radioactivity is basically retained at the injection site, other Hospital staff (surgeons, nurses, pathologists,...) will be exposed to the gamma radiation from the procedure. In this study we estimated maximum possible doses that would be received by the surgical staff during surgery and pathologies during lumpectomy of the sentinel node. For the first ones we estimated doses by taking into account only the physical decay of Tc99m injected. For the pathologists, we estimated the residual activity in the sentinel node with the gamma probe. The highest effective dose rate found was to the surgeon (=,66μSv/h). Effective dose rate to the pathologist was lower than 0,02μSv/h. Estimated dose rate to surgeon and pathologists hands were 182 and 30 μSv/h, respectively. In conclusion, radiation doses to clinical staff involved in the technique are low,and in normal conditions, by establishing appropriate procedures control radiation will not be necessary.

  17. Node Survival in Networks under Correlated Attacks.

    Hao, Yan; Armbruster, Dieter; Hütt, Marc-Thorsten

    2015-01-01

    We study the interplay between correlations, dynamics, and networks for repeated attacks on a socio-economic network. As a model system we consider an insurance scheme against disasters that randomly hit nodes, where a node in need receives support from its network neighbors. The model is motivated by gift giving among the Maasai called Osotua. Survival of nodes under different disaster scenarios (uncorrelated, spatially, temporally and spatio-temporally correlated) and for different network architectures are studied with agent-based numerical simulations. We find that the survival rate of a node depends dramatically on the type of correlation of the disasters: Spatially and spatio-temporally correlated disasters increase the survival rate; purely temporally correlated disasters decrease it. The type of correlation also leads to strong inequality among the surviving nodes. We introduce the concept of disaster masking to explain some of the results of our simulations. We also analyze the subsets of the networks that were activated to provide support after fifty years of random disasters. They show qualitative differences for the different disaster scenarios measured by path length, degree, clustering coefficient, and number of cycles. PMID:25932635

    This paper firstly proposes a three-layered NodeOS structural model that divides the functionality of NodeOS among hardware abstraction layer, resource man-agement layer and API layer, and discusses the primary functions of each layer. NodeOS built on this model will be open and programmable. Then, from the view of supporting fair and customized services, this paper puts forward a general NodeOS service model that defines threetypes of NodeOS services according to the tradeoiT between quality of service and cost of service, then specifies a general method to map special application-oriented services to NodeOS services, and lastly discusses the resource allocation policies and corresponding enforcement mechanisms. Finally, after analyzing the security requirements of active net, this paper puts forward a general but powerful security architecture for NodeOS, which embeds elementary security mechanisms in NodeOS by enforcing well-designed domain relations and encapsulating sensitive underlying interfaces, and provides further security services of authorization management and packet checking by integrating additional service facilities.

  19. Predicting missing links via correlation between nodes

    Liao, Hao; Zeng, An; Zhang, Yi-Cheng

    2015-10-01

    As a fundamental problem in many different fields, link prediction aims to estimate the likelihood of an existing link between two nodes based on the observed information. Since this problem is related to many applications ranging from uncovering missing data to predicting the evolution of networks, link prediction has been intensively investigated recently and many methods have been proposed so far. The essential challenge of link prediction is to estimate the similarity between nodes. Most of the existing methods are based on the common neighbor index and its variants. In this paper, we propose to calculate the similarity between nodes by the Pearson correlation coefficient. This method is found to be very effective when applied to calculate similarity based on high order paths. We finally fuse the correlation-based method with the resource allocation method, and find that the combined method can substantially outperform the existing methods, especially in sparse networks.

    2008-12-01

    Full Text Available Reduction in size and power consumption of consumer electronics has opened up many opportunities for low power wireless sensor networks. One of the major challenges is in supporting battery operated devices as the number of nodes in a network grows. The two main alternatives are to utilize higher energy density sources of stored energy, or to generate power at the node from local forms of energy. This paper reviews the state-of-the art technology in the field of both energy storage and energy harvesting for sensor nodes. The options discussed for energy storage include batteries, capacitors, fuel cells, heat engines and betavoltaic systems. The field of energy harvesting is discussed with reference to photovoltaics, temperature gradients, fluid flow, pressure variations and vibration harvesting.

  2. Node degree distribution in spanning trees

    International Nuclear Information System (INIS)

    A method is presented for computing the number of spanning trees involving one link or a specified group of links, and excluding another link or a specified group of links, in a network described by a simple graph in terms of derivatives of the spanning-tree generating function defined with respect to the eigenvalues of the Kirchhoff (weighted Laplacian) matrix. The method is applied to deduce the node degree distribution in a complete or randomized set of spanning trees of an arbitrary network. An important feature of the proposed method is that the explicit construction of spanning trees is not required. It is shown that the node degree distribution in the spanning trees of the complete network is described by the binomial distribution. Numerical results are presented for the node degree distribution in square, triangular, and honeycomb lattices. (paper)

    Real networks exhibit heterogeneous nature with nodes playing far different roles in structure and function. To identify vital nodes is thus very significant, allowing us to control the outbreak of epidemics, to conduct advertisements for e-commercial products, to predict popular scientific publications, and so on. The vital nodes identification attracts increasing attentions from both computer science and physical societies, with algorithms ranging from simply counting the immediate neighbors to complicated machine learning and message passing approaches. In this review, we clarify the concepts and metrics, classify the problems and methods, as well as review the important progresses and describe the state of the art. Furthermore, we provide extensive empirical analyses to compare well-known methods on disparate real networks, and highlight the future directions. In despite of the emphasis on physics-rooted approaches, the unification of the language and comparison with cross-domain methods would trigger int...

    2012-03-01

    Full Text Available This paper presents a new method for finding the node-disjoint paths with maximum combined bandwidth in communication networks. This problem is an NP-complete problem which can be optimally solved in exponential time using integer linear programming (ILP. The presented method uses a maximum-cost variant of Dijkstra algorithm and a virtual-node representation to obtain the maximum-bandwidth node-disjoint path. Through several simulations, we compare the performance of our method to a modern heuristic technique and to the ILP solution. We show that, in a polynomial execution time, our proposed method produces results that are almost identical to ILP in a significantly lower execution time

    2007-10-01

    Full Text Available Abstract Background The 5-year survival rate in patients with gastric cancer is still poor, and lymph node metastasis is considered one of the most important prognostic factors. However, there are controversies in the classification of lymph node metastasis in gastric cancer. This study was carried out to investigate whether the metastatic lymph node ratio is a reliable classification of lymph node metastasis in gastric cancer in Chinese. Methods 224 cases with gastric cancer with more than D1 dissection were retrospectively reviewed. The association between the total number of resected lymph nodes and the number of metastatic lymph nodes was determined. The prognostic value of the metastastic node ratio, defined as the ratio of the number of metastatic lymph nodes over the total number of resected lymph nodes, and the pN classification was assessed. Results The number of metastatic lymph node increased with the number of total resected lymph nodes. A Cox regression revealed that the metastatic node ratio, the number of metastatic nodes, histological type, and histological growth pattern independently influenced prognosis. The 5-year survival rates were 78%, 61%, 25%, 0% in cases with a metastastic node ratio of 0%, > 0% but 80%, respectively (P P Conclusion The metastatic lymph node ratio is a simple and useful independent prognostic factor. It may obviate possible confounding factors that are related to stage migration, and should be considered as an important component in the lymph node category.

    Among patients with Wolff-Parkinson-White syndrome, atrioventricular reciprocating tachycardia (AVRT) and atrioventricular nodal reentrant tachycardia (AVNRT) can coexist in a single patient. Direct transition of both tachycardias is rare; however, it can occur after premature atrial or ventricular activity if the cycle lengths of the two tachycardias are similar. Furthermore, persistent atrial activation by an accessory pathway (AP) located outside of the AV node during ongoing AVNRT is also rare. This article describes a case of uncommon atrial activation by an AP during AVNRT and gradual transition of the two supraventricular tachycardias without any preceding atrial or ventricular activity in a patient with preexcitation syndrome.

    2011-01-01

    State machines are hierarchical automata that are widely used to structure complex behavioural specifications. We develop two notions of refinement of state machines, node refinement and edge refinement. We compare the two notions by means of examples and argue that, by adopting simple conventions......, they can be combined into one method of refinement. In the combined method, node refinement can be used to develop architectural aspects of a model and edge refinement to develop algorithmic aspects. The two notions of refinement are grounded in previous work. Event-B is used as the foundation for our...

    [english] The lymph nodes are an essential part of the body’s immune system and as such are affected in many infectious, autoimmune, metabolic and malignant diseases. The cervical lymph nodes are particularly important because they are the first drainage stations for key points of contact with the outside world (mouth/throat/nose/eyes/ears/respiratory system) – a critical aspect especially among children – and can represent an early clinical sign in their exposed position on a child’s slim ne...

  13. The value of peripheral nodes in controlling multilayer networks

    CERN Document Server

    Zhang, Yan; Schweitzer, Frank

    2015-01-01

    We analyze the controllability of a two-layer network, where driver nodes can be chosen only from one layer. Each layer contains a scale-free network with directed links. The dynamics of nodes depends on the incoming links from other nodes (reputation dynamics). We find that the controllable part of the network is larger when choosing peripherial nodes to connect the two layers. The control is as efficient for peripherial nodes as driver nodes as it is for more central nodes. If we assume a cost to utilize nodes which is proportional to their degree, utilizing peripherial nodes to connect the two layers or to act as driver nodes is not only the most cost-efficient solution, it is also the one that gives us the best performance in controlling the two-layer network.

    Sentinel lymph nodes have been found to be an indicator of lymph node metastasis in breast cancer. In Japan, the theory and concept of sentinel lymph nodes in breast cancer have begun to be applied to carcinomas of the digestive system. Based on clinical experience in the detection of sentinel lymph nodes with radiopharmaceuticals, differences and similarities between the radiopharmaceuticals, methods, and techniques used to detect sentinel lymph nodes have been assessed in relation to breast cancer and carcinomas of the digestive system (including carcinomas of the esophagus and large intestine). The greatest difference between the methods used for breast and digestive cancers is the site of administration of the radiopharmaceutical. In breast cancer, the radiopharmaceutical is administered into a superficial organ (i.e., the mammary gland), whereas in carcinomas of the digestive system, it is administered into a deep organ (i.e., digestive tract). Another obvious difference is in lymph flow, i.e., the flow of the mammary glands is subcutaneous whereas lymph flow in the digestive tract is submucosal. Two radionuclide diagnostic methods are available to detect sentinel lymph nodes: sentinel lymphoscintigraphy with a gamma camera and a method that involves the use of a gamma probe intraoperatively. Radiopharmaceuticals used to detect sentinel lymph nodes must be smoothly transferred from the site of administration into the lymph, and uptake by the sentinel lymph node must continue for a long time without excessive flowing to lower reaches. The optimal particle size remains a matter of controversy, and no radiopharmaceuticals appropriate for lymphoscintigraphy have ever been approved in Japan. The authors compared the pharmacokinetics of three different radiopharmaceuticals used for sentinel lymphoscintigraphy in breast cancer ({sup 99m}Tc-labeled albumin, {sup 99m}Tc-labeled tin colloid, and {sup 99m}Tc-labeled phytic acid) and founded that the detection rate was

  4. Lymphatic drainage and sentinel node location in breast cancer

    International Nuclear Information System (INIS)

    Full text: Mammary lymphoscintigraphy using small volume (0.1-0.2 ml) peritumoral injections of 99Tcm-antimony sulphide colloid provided a map of the lymph drainage of a breast cancer to its draining sentinel lymph nodes in 92 of 102 patients (over 90%). Non-migration of tracer is reduced by post-injection massage for 5 min but may occur especially if the lymphatics are blocked by metastases. Drainage included the axilla in 92%, internal mammary nodes in 43%, supraclavicular nodes in 12% and intramammary interval nodes in 10% of patients. One patient drained to an interpectoral node. Drainage across the centre-line of the breast occurred in 46% of patients but direct drainage to the contralateral side of the patient was not seen. Lymphatic drainage occurred to 1 node field in 52 patients, 2 node fields in 34 patients and 3 node fields in 6 patients, so that 43% of patients had multiple draining node fields. Drainage to non-axillary sites occurred in 51% of patients. In conclusion, mammary lymphoscintigraphy accurately maps sentinel node location in breast cancer. Approximately half of the patients will have sentinel nodes outside the axilla. To achieve complete lymph node staging in patients with breast cancer, it is logical to biopsy these non-axillary sentinel nodes as well as the sentinel nodes in the axilla. Failure to do so will potentially understage the node status in 50% of patients

Den beskriver omstendighetene som medførte at standarden ble til i 1984, og søker å forklare hvorfor og hvordan det lyktes å utbre standarden slik at Noark-systemer ble enerådende i offentlig forvaltning i løpet av 1990-årene. Riksarkivarens strategier i Noark-utviklingen behandles, – de som fra først av fikk Riksarkivaren til å engasjere seg i standardiseringsarbeidet, de som deretter fikk Riksarkivaren til å overta forvalteransvaret for Noark, og de som senere er endret eller justert som resultat av erfaringer med Noark-baserte systemer og av nyåpnede teknologiske muligheter. Særlig vekt legges på å belyse Riksarkivarens motiver for å overta ansvaret for Noark-standarden fra 1990. Noark plasseres også i det internasjonale bildet, og sammenholdes med andre standarder som ISO 15489 og EU-standarden MoReq. Da Noark-utviklingen startet i 1984, pågikk tilsvarende utviklingsprosjekter både i Danmark og i Sverige. Artikkelen søker forklaringer på at en journal- og sakarkivstandard bare ble en realitet i Norge.

    The weight of links in a network is often related to the similarity of the nodes. Here, we introduce a simple tunable measure for analysing the similarity of nodes across different link weights. In particular, we use the measure to analyze homophily in a group of 659 freshman students at a large university. Our analysis is based on data obtained using smartphones equipped with custom data collection software, complemented by questionnaire-based data. The network of social contacts is represented as a weighted multilayer network constructed from different channels of telecommunication as well as data on face-to-face contacts. We find that even strongly connected individuals are not more similar with respect to basic personality traits than randomly chosen pairs of individuals. In contrast, several socio-demographics variables have a significant degree of similarity. We further observe that similarity might be present in one layer of the multilayer network and simultaneously be absent in the other layers. For a variable such as gender, our measure reveals a transition from similarity between nodes connected with links of relatively low weight to dis-similarity for the nodes connected by the strongest links. We finally analyze the overlap between layers in the network for different levels of acquaintanceships. PMID:27300084

    Lymph nodes were examined from 41 cases of typical chronic lymphocytic leukemia (CLL). Degree of immaturity was graded as absent to minimal (Grade I), moderate (Grade II) and marked (Grade III). A moderate degree of immaturity was found in the lymph node in 14 of 41 cases even though the cells seen on the initial bone marrow and peripheral blood smears obtained from these patients were essentially all mature. The morphology of these nodes could be confused with poorly differentiated lymphocytic or mixed lymphocytic-histiocytic lymphoma in terms of the degree of immaturity present. A marked degree of immaturity present. A marked degree of immaturity was found in 5 cases; the morphology of these cases resembled histiocytic lymphoma. In the remaining 22 cases immaturity was essentially absent. The morphology of these cases was similar to that of diffuse well differentiated lymphocytic lymphoma. Our studies suggest that a moderate degree of immaturity in the lymph node of patients with CLL does not indicate that these patients will have a marked shortening of their survival. PMID:580071

In this paper, we present an improved iterative resource allocation (IIRA) method by considering the centrality information of neighbors and the influence of spreading rate for a target node. Comparing with the results of the Susceptible Infected Recovered (SIR) model for four real networks, the IIRA method could identify influential nodes more accurately than the tradition IRA method. Specially, in the Erdos network, the Kendall's tau could be enhanced 23\\% when the spreading rate is 0.12. In the Protein network, the Kendall's tau could be enhanced 24\\% when the spreading rate is 0.08.

    Lymph node status is a key prognostic factor in penile squamous cell carcinoma.Recently,growing evidence indicates a multimodality approach consisting of neoadjuvant chemotherapy followed by consolidation surgery improves the outcome of locally advanced penile cancer.Thus,accurate estimation of survival probability in node-positive penile cancer is critical for treatment decision making,counseling of patients and follow-up scheduling.This article reviewed evolving developments in assessing the risk for cancer progression based on lymph node related variables,such as the number of metastatic lymph nodes,bilateral lymph node metastases,the ratio of positive lymph nodes,extracapsular extension of metastatic lymph nodes,pelvic lymph node metastases,metastatic deposit in sentinel lymph nodes and N stage in TNM classification.Controversial issues surrounding the prognostic value of these nodal related predictors were also discussed.

    Full Text Available El cuadro clínico de la tirotoxicosis incluye síntomas cardiovasculares variados. La taquicardia sinusal es el trastorno electrocardiográfico más frecuente y los trastornos de conducción son extremadamente raros como modo de presentación. Comunicamos un caso de bloqueo aurículo-ventricular de primer grado en una paciente con hipertiroidismo recién diagnosticado y que comenzó días antes de la consulta con un cuadro general inespecífico. Su evaluación ulterior demostró que se trataba de una tirotoxicosis aguda autoinmune, y su tratamiento con metimazol corrigió el trastorno totalmente. Se discuten los mecanismos fisiopatológicos involucrados y las implicancias clínicas desde el punto de vista del internista.Thyrotoxicosis may present with a variety of cardiovascular symptoms. Sinus tachycardia is the most frequently encountered electrocardiographic abnormality and conduction disturbances are extremely uncommon. We present a case of first degree atrio-ventricular block in a patient with newly diagnosed hyperthyroidism and discuss the underlying pathophysiological mechanisms and the clinical implications from the internist’s standpoint.

    Despite the deleterious effects of cardiac dyssynchrony and the positive effects of cardiac resynchronization therapy, patients with high-degree atrioventricular block continue to receive desynchronizing right ventricular (RV) pacing systems. Although it is unclear whether the negative effects of RV pacing and left bundle branch block (LBBB) are comparable, and whether they depend on the presence and the degree of structural heart disease, one may hypothesize that RV pacing may have similar effects to LBBB. In the BioPace trial, the long-term effects of RV pacing vs. biventricular pacing will be prospectively compared in 1200 pacemaker patients with high likelihood of mostly paced ventricular events, regardless of whether in sinus rhythm or in atrial fibrillation (AF). After echocardiographic examination of left ventricular (LV) function, patients will be randomly assigned to the implantation of an RV vs. a biventricular pacing system and followed for up to 5 years. Primary study endpoints are survival, quality of life (QoL), and the distance covered in a 6-min hall walk (6-MHW) at 24 months after implantation. Secondary endpoints are QoL and the 6-MHW result at 12 months after implantation, hospitalization rate, LV dimensions, LV ejection fraction, and the development of chronic AF and other adverse events.
