Resumen en español El surco diagonal es un signo encontrado en el lóbulo de la oreja, que estaría relacionado con la enfermedad arterial coronaria. Nuestro objetivo fue estudiar la utilidad del signo. Se examinaron 104 pacientes (entre 30 y 80 años) clasificados por sexo y edad. Cuarenta y nueve tenían enfermedad arterial coronaria diagnosticada por coronariografía (obstrucción > del 70% en una de las grandes arterias) y/o gamagrafía de perfusión miocárdica con Talio 201 (defecto f (mas) ijo). El grupo control estuvo compuesto por 55 pacientes (asintomáticos, con electrocardiograma normal). Los datos obtenidos fueron sensibilidad (61.2%), especificidad (78.2%), valor predictivo positivo de (71.4%) y valor predictivo negativo (69.3%.). Observamos una relación significativa entre la presencia de surco diagonal y enfermedad arterial coronaria. Consideramos que este signo podría resultar de utilidad en la práctica clínica, fundamentalmente para los pacientes entre 30 y 60 años. Resumen en inglés The diagonal earlobe crease is a sign theorically related to coronary artery disease. The purpose of this study was to prove the usefulness of this sign. A total of 104 patients were examined (ages 30 to 80) grouped by age and sex. Forty nine of them were diagnosed of having coronary artery disease by coronary angiography (a 70% obstruction of one of the major arteries), and/or myocardial perfusion imaging with Thallium 201 (fixed defects). The control group included 55 p (mas) atients (asymptomatic with normal electrocardiogram). Data here obtained included sensitivity (61.2%), specificity (78.2%), positive predictive value (71.4%) and negative predictive value (69.3%). We found a significant relation between the presence of the diagonal earlobe crease and coronary artery disease. We consider it a sign that could prove useful in clinical practice, mainly among patients aged between 30 and 60.

Resumen en español Se revisan las aplicaciones comunes de las técnicas de medicina nuclear en cardiología. La más importante y prevalente patología cardiovascular en países desarrollados y también en Chile es la enfermedad coronaria. Diferentes aproximaciones pueden ser empleadas para su estudio, pronóstico, estadificación de riesgo y evaluación preoperatoria. Se revisan, además, el infarto miocárdico y el reconocimiento de isquemia con estudio de perfusión incluyendo nuevos pro (mas) tocolos que aplican pro- ducción de isquemia; el valor diagnóstico del SPECT de perfusión, el uso de Talio; Tc-99m Sestamibi e imágenes metabólicas con Flúor-18- Fluorodeoxiglucosa son también mencionadas Resumen en inglés The current applications of nuclear cardiology techniques are reviewed. Coronary artery disease is the most important and prevalent cardiovascular problem in most developed countries and also in Chile. Different approaches can be employed for its diagnosis and prognosis, as well as for risk stratification and preoperative evaluation. Myocardial infarction assessment and ischemia recognition with radionuclide perfusion images are also reviewed, including new protocols appl (mas) ying functional parameters addition. Viability detection after myocardial infarction or in patients with ischemic cardiomyopathy are discussed. Stress protocols with the use of exercise or pharmacological action for ischemia production, the diagnostic value of perfusion SPECT and the use of Thallium-201, Tc-99m-Sestamibi and metabolic images with Fluorine18-Fluordeoxyglucose are also mentioned

Resumen en inglés Background: The detection of viability after acute myocardial infarction is primordial to select the most appropriate therapy, to decrease cardiac events and abnormal remodeling. Thallium201 SPECT is one of the radionuclide techniques used to detect viability. Aim: To evaluate the use of Thallium201 rest-redistribution SPECT to detect myocardial viability in reperfused patients after a recent myocardial infarction. Patients and methods: Forty one patients with up to of 24 (mas) days of evolution of a myocardial infarction were studied. All had angiographically demonstrated coronary artery disease and were subjected to a successful thrombolysis, angioplasty or bypass grafting. SPECT Thallium201 images were acquired at rest and after 4 h of redistribution. These results were compared with variations in wall motion score, studied at baseline and after 3 or 4 months with echocardiography. Results: The sensitivity of rest-redistribution Thallium201 SPECT, to predict recovery of wall motion was 91% when patient analysis was performed and 79% when segmental analysis was done in the culprit region. The figures for specificity were 56 and 73% respectively. Conclusions: Rest-distribution Thallium201 SPECT has an excellent sensitivity to predict myocardial viability in recent myocardial infarction. The data obtained in this study is similar to that reported for chronic coronary artery disease (Rev Méd Chile 2002; 130: 243-50)

Enfermedad coronaria aneurismática severa en un adolescente con angina de esfuerzo secundaria a enfermedad de Kawasaki no diagnosticada previamente/ Severe aneurisma I coronary artery disease probably caused by Kawasaki disease. Report of one case

Resumen en inglés We report a 16 year old male with a history of angina on exertion. A treadmill exercise test was positive for ischemia in concordance with a Thallium-201 scintigraphy showing a septal and infero-posterior reversible myocardial perfusión defect. Coronary angiography disclosed severe aneurysmal coronary artery disease. Bilateral internal mammary coronary artery bypass grafting was successfully performed. Kawasaki disease is the most likely etiology, although not confirmed
