Enfermedad coronaria aneurismática severa en un adolescente con angina de esfuerzo secundaria a enfermedad de Kawasaki no diagnosticada previamente

Abstract: 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-201scintigraphy showing a septal and infero-posterior reversible myocardial perfusion defect.Coronary angiography disclosed severe aneurysmal coronary artery disease. Bilateral internalmammary coronary artery bypass grafting was successfully performed. Kawasaki disease is themost likely etiology, although not confirmed (Rev Med Chile 2007; 135: 1182-85).(

Displasia arritmogénica del ventrículo derecho con compromiso de ventrículo izquierdo: valor diagnóstico de la resonancia cardiaca

Abstract: Arrhythmogenic right ventricular dysplasia is an inherited condition characterized by replacement of normal myocardium by fatty or fibro-fatty tissue, which mainly affects the right ventricle. The most frequent form of presentation is ventricular tachycardia or sudden death, whose origin is considered to be a product of fibrous or fatty infiltration of the myocardium. This structural damage can be detected by cardiac magnetic resonance imaging (MR). We report two patients with ventricular tachycardia due to arrhythmogenic right ventricular dysplasia. A 49 year-old female with a history of ventricular tachycardia. EKG showed epsilon waves and a prolonged QTc. Echocardiogram showed right ventricular dilatation and dysfunction. MR showed right ventricular fatty infiltration. An implantable cardioverter-defibrillator was installed to the patient. A 37 year-old male was admitted for recurrent syncope. On admission a ventricular tachycardia was detected. An echocardiogram showed right ventricular dilatation and dysfunction. MR showed a large zone of fibrosis in the right ventricle. An implantable cardioverter-defibrillator was also installed.

Application of Percutaneous Transluminal Coronary Angioplasty to Coronary Arterial Stenosis in Kawasaki Disease

Abstract: Background Percutaneous transluminal coronary angioplasty (PTCA) has rarely been performed on patients with coronary lesions that result from Kawasaki disease. In this study, we retrospectively evaluated the effectiveness of PTCA in five patients with coronary arterial stenosis that resulted from Kawasaki disease and reviewed previous reports for possible indicators of PTCA effectiveness. Methods and Results Five patients, ranging in age from 2 to 16 years (median, 8 years), underwent conventional PTCA for localized stenosis. The lesion targeted for PTCA was located in the middle right coronary artery of three patients and in the left anterior descending artery in two patients. In four of the five patients, PTCA was angiographically effective, with stenosis rates improving from 84±10% to 33±11% (P<.05). When the previously reported cases of six similar patients were taken into consideration, the only predictor of successful PTCA seemed to be the time elapsed between the onset of Kawasaki disease and perfo...
