BACKGROUND Total anomalous pulmonary venous drainage (TAPVD) is a rare disease, with an approximate incidence of 0.058 to 0.083:1,000 live births. It has a mortality rate of around 80% to 90% in the first year, if not treated early. OBJECTIVE Using the 29-year experience of a single center, possible variables related to hospital death were tested. (More)
Two female patients, 54 and 38 years-old with refractory ventricular tachycardia were undertaken to electrophysiologic study for diagnosis and radiofrequency ablation of their arrhythmias. The tachycardias were only inducible with intravenous isoproterenol infusion. The site of the origin of ventricular tachycardia was localized in the right ventricular(More)
PURPOSE To localize the site of the origin of sustained ventricular tachycardia in chronic chagasic cardiomyopathy patients refractory to antiarrhythmic therapy by radionuclide angiography techniques. METHODS Five patients underwent radionuclide angiography by intravenous administration of 25mCi 99mTc. The images were obtained in sinus rhythm and during(More)
