INTRODUCTION Right ventricular infarction, previously thought to be rare and recently thought to be common, is commonly associated with inferior wall myocardial infarction. We will hereby study the clinical profile of right ventricular infarction (as diagnosed by right precordial electrocardiography) in patients with acute inferior wall myocardial infarction and the clinical course of RV infarc...

OBJECTIVE To determine the diagnostic and prognostic impact of abnormal Q waves in comparison to or in combination with ST segment abnormalities in the right precordial and inferior leads as indicators of right ventricular infarction during the acute phase of inferior myocardial infarction. DESIGN Prospective study of a consecutive series of 200 patients with acute inferior myocardial infarct...

The appearance of the right ventricular myocardium on thallium 201 myocardial perfusion images was evaluated in patients with chronic pulmonary hypertension and compared to patients without pulmonary hypertension. Four groups of patients were studied: 1) eight normals, 2) five patients with angiographically documented coronary artery disease and normal pulmonary artery pressures, 3) ten patient...

Thallium-201 myocardial scintigraphy was performed in patients with congenital heart defects to determine whether, by quantification of right ventricular isotope uptake, one could assess the degree of right ventricular hypertrophy and so predict the level of right ventricular pressure. A total of 24 patients ranging in age from 7 months to 30 years was studied; 18 were studied before corrective...

BACKGROUND Preoperative factors associated with increased mortality and worse outcome after tricuspid valve replacement in patients with severe tricuspid regurgitation are poorly understood. METHODS AND RESULTS We retrospectively analyzed 189 patients (37% men; age, 67.5±11.3 years) who underwent tricuspid valve replacement for severe tricuspid regurgitation. Operative mortality rate was 10%,...

The early (after 21 days) and late (after 4 months) effects of continuous treatment with captopril on left ventricular performance, weight and volumes were studied in rats with myocardial infarction. Early effects were examined in rats subjected to coronary ligation and randomized to either immediate treatment with captopril (2 g/liter drinking water) starting 2 h after surgery or no treatment....

Myocardial fiber diameters were measured to determine their distribution throughout the ventricular wall in normal adult hearts, hypertensive hearts and hearts with hypertrophic cardiomyopathy (HCM). In normal adult hearts and hypertensive hearts, the diameter decreased from the inner to the outer third of the left ventricular free wall and from the left ventricular side to the right ventricula...
