It has been suspected that the increased sympathetic activity seen in patients with chronic congestive heart failure from dilated cardiomyopathy may be harmful. We therefore tested the long-term effect of metoprolol on eight patients in a double-blind, randomized protocol and 12 patients in an unblinded, crossover protocol who were treated for 12 months(More)
We reviewed the transpulmonary gradient, pulmonary arterial systolic pressure, pulmonary vascular resistance (Wood units), and pulmonary vascular resistance index (Wood units X Body surface area), recorded preoperatively in 109 recipients aged 44.6 +/- 13.5 (mean +/- SD) years who underwent orthotopic heart transplantation between March 1984 and March 1988,(More)
This study reports the intraoperative use of contrast and Doppler echocardiography techniques to diagnose patent foramen ovale (PFO). Fifty patients without known atrial septal defects undergoing elective cardiovascular surgery were studied. A 5-MHz esophageal echocardiographic probe was used to image the fossa ovalis (FO) and 10 ml agitated saline was(More)
Exercise-induced bundle branch block is an uncommon electrocardiographic entity said to be associated with coronary heart disease. Thirty-seven patients were studied to determine if exercise hemodynamics and stress/rest thallium scans could identify those patients with coronary heart disease. Eighteen patients of the study group also had coronary(More)
The optimal visualization of the atrial septum and fossa ovalis by transesophageal echocardiography was utilized to demonstrate saline contrast transit across the atrial septum and to relate it to the motion of the flap valve (septum primum) of the fossa ovalis. In three cases, three distinct mechanisms of right to left interatrial shunting in the absence(More)
One hundred seventy patients with syncope presenting to an emergency department were studied prospectively. A checklist was used to supplement the physician's history and physical to ensure adequate recording of potentially useful data. Follow-up data were available in 89% of patients with a mean follow-up period of 6.2 months. Patients were categorized by(More)
T his document revises and updates the original " Guidelines for Coronary Angiography, " published in 1987. both the full text and executive summary and recommendations are available from both organizations. The frequent and still growing use of coronary angiogra-phy, its relatively high costs, its inherent risks, and the ongoing evolution of its(More)
Two cases of acute myocardial infarction occurred in association with myocarditis, which was confirmed by biopsy. The first patient suffered an anteroseptal and the second patient an inferior wall myocardial infarction shortly after an acute viral illness. In both patients, coronary angiography showed normal coronary arteries, and right ventricular(More)
