Purpose: To study the correlation between magnetic resonance imaging of the heart and right ventricle endomyocardial biopsy results in chronic Chagas' heart disease.

Methods: Ten patients with Chagas' disease, mean age 47 +/- 7 years, all males, in congestive heart failure with New York Heart Association class II (2 patients), III (6) and IV (2) were studied. Mean left ventricular ejection fraction was at echocardiogram 36 +/- 6%.

[Evaluation of chronic morphological changes in the latissimus dorsi, after cardiomyoplasty, with magnetic resonance].

Purpose: Long term clinical and hemodynamic benefits of dynamic cardiomyoplasty (DC) have been reported. However, no information is available about long-term morphological changes in the wrapped latissimus dorsi (LD) muscle in humans.

Methods: The latissimus dorsi muscle flap was evaluated by magnetic resonance imaging (MRI) in 5 patients submitted to DC for treatment of severe dilated cardiomyopathy.

[A false diagnosis of hypertrophic myocardiopathy in pheochromocytoma].

A 24 year-old man was admitted with hypertensive crises and diagnosis hypothesis of neurofibromathosis and pheochromocytoma with blood pressure of 150 x 110mmHg and in use of anti-hypertensive drugs. The electrocardiogram (EKG) showed left ventricle hypertrophy. An echocardiogram showed interventricular septum (IVS) thickness of 16mm, posterior wall (PW) thickness of 11mm (ratio IVS/PW was 1.

[Postoperative course of left ventricular function in aortic insufficiency].

Purpose: To analyze the follow-up of left ventricular function (LVF) after surgical correction of severe chronic aortic insufficiency (AI).

Methods: Twenty-one out of 68 patients with AI, initially asymptomatic and that developed symptoms during the follow-up period of 24-36 months, were studied. Relationship between symptoms and LVF by echocardiogram and radioisotopic ventriculography at rest and in isotonic exercise were studied.

[Role of circumflex coronary artery involvement in non-Q wave myocardial infarction].

Purpose: To determine the patency and incidence rates of left circumflex coronary artery (LCX) as the infarct related artery (IRA) in Q-wave and non-Q wave acute myocardial infarction (AMI).

Methods: Two-hundreds and twenty one patients (172 men) with AMI were stratified in Q and non-Q waves groups. All patients were submitted to cinecoronary angiography 72 hours after the beginning of symptoms and the IRA and its patency were evaluated.

[Preoperative erythrocytopheresis in a patient with SC hemoglobinopathy and mitral stenosis].

Hemoglobinopathies are associated with thrombotic complications, when exposed to cardiopulmonary bypass. A 54-year old, black woman with hemoglobinopathy SC and severe mitral stenosis was submitted to eritrocytopheresis 48 hours before mitral commissurotomy surgery. The therapeutic determined appearance of the percentual hemoglobin A of 68% with reduction the hemoglobin S of 48% to 15% and the hemoglobin C of 51% to 17%.
