Anomalous origin of one pulmonary artery from the ascending aorta without associated intracardiac defects is a rare congenital malformation. About 60 anatomic and surgical descriptions have been reported in the literature. Up to 1974, 22 of the 50 reported cases underwent surgical correction with a 40% mortality rate. The natural history without surgery is(More)
An unexpected clinical presentation of an unusual pacing failure has been observed in two patients who had had recent implantation of a pacemaker model whose electrodes were made of an nonnoble metal alloy. An intermittent current leakage from the output capacitor and possibly from the output transistor accounted for electrolytic corrosion at the anode,(More)
Giant left atrium (GLA) associated with mitral valve disease (MVD) has been reported as a significant risk factor in mitral valve surgery with mortality ranging from 8%-32%. Plication of the left atrium has been suggested to reduce postoperative left ventricular failure, respiratory failure and mortality. The 203 consecutive patients with MVD operated upon(More)
OBJECTIVE Transoesophageal echocardiography (TEE) is recognized to be superior to transthoracic echocardiography (TTE) in evaluating complications of infective endocarditis (IE). The aim of this study was to compare results from TTE and TEE with surgical findings, and to assess limitations and discrepancies of TEE as compared with surgical findings. (More)
BACKGROUND AND OBJECTIVE Elective native coronary artery stenting has shown its efficacy in lowering restenosis rates (RR) usually occurring after balloon angioplasty (PTCA). However ability of conventional PTCA to consistently provide low RR, through the achievement of large acute stent-like angiographic results, has not been investigated. This study was(More)
Atrial pacing to the point of angina or up to a maximum rate of 166/min was carried out in 37 patients during coronary angiography. In 9 patients with normal coronary arteries both the right and left ventricular end-diastolic pressures fell remained steady with increasing heart rate. The same response was observed in 14 patients with angiographically(More)
Nine patients with aortic root dilatation without dissection and four patients with a dissecting aneurysm of the ascending aorta were studied with single-plane echocardiography. Previously reported echocardiographic findings, which have been shown to be similar in these two groups of patients, are confirmed. In addition to (a) aortic root dilatation, (b)(More)
