BACKGROUND Because heterogeneous results have been reported, we assessed coronary flow velocity changes in individuals who underwent percutaneous transluminal coronary angioplasty (PTCA) and examined their impact on clinical outcome. METHODS AND RESULTS As part of the Doppler Endpoints Balloon Angioplasty Trial Europe (DEBATE) II study, 379 patients underwent Doppler flow-guided angioplasty. ...

Objectives. We sought to assess the angiographic outcome, complication rates and clinical features of percutaneous transluminal coronary angioplasty (PTCA) after failed thrombolysis for acute myocardial infarction. Background. “Rescue angioplasty” refers to mechanical reopening of an occluded infarct-related artery (IRA) after failed intravenous thrombolysis. Although the procedure is commonly ...

A study was undertaken to evaluate the significance of elevated troponin-T after perculaneous transluminal coronary angioplasty (PTCA) in 52 patienrs. After PTCA, 35 palients (67.3%ù showed elevated TnT. Except in one patient who developed heartfailure, the other patients-had uneventful clinical course. l[/e conclude that PTCA might induce minor myocardial injury, which is no! associated with i...

severe coronary artery disease often coexists with peripheral vascular atherosclerosis. the assessment of the supra-aortic circulation is, therefore, of clinical relevance. we herein describe a case of coronary artery disease treated with surgical revascularization using the internal mammary artery and thereafter the progressive atherosclerotic disease of the native coronary arteries as well as...

OBJECTIVES How effective and safe is rescue percutaneous transluminal coronary angioplasty [PTCA] compared with primary PTCA, and is it cost effective? BACKGROUND In acute myocardial infarction (AMI), primary PTCA has been shown to be beneficial in terms of clinical outcome. In contrast, the value of rescue PTCA has not been established. METHODS In a retrospective analysis, we compared the ...

Background. Cilazapril is a novel angiotensin converting enzyme inhibitor with antiproliferative effects in the rat model after balloon injury. Methods and Results. We conducted a randomized, double-blind placebo-controlled trial to assess the effect of cilazapril in angiographic restenosis prevention after percutaneous transluminal coronary angioplasty (PTCA). Patients received cilazapril 2.5 ...

Left ventricular performance during percutaneous transluminal coronary angioplasty was assessed in 52 patients by intravenous digital subtraction ventriculography. After injection of contrast into the right atrium ventriculograms were obtained before and during balloon inflation. In 37 patients they were also obtained after the procedure. A 12 lead electrocardiogram was monitored throughout. Du...

Cardiac interventional radiology (IVR) has gained popularity since the late 1980s. An extensive search of literature published from 1996 to 2009 identified 78 reports regarding radiation-induced skin injuries (RISI) following cardiac IVR. The authors present a case report and a review of the relevant literature. A 59-year-old man underwent percutaneous transluminal coronary angioplasty (PTCA). ...

We studied 25 patients who underwent percutaneous transluminal coronary angioplasty (PTCA) to determine the association of sympathovagal imbalance and the outcome of coronary angioplasty. We examined the profiles of heart rate variability (HRV) using echocardiography, stress thallium scanning and radionuclide angiography before, immediately after and 1 month after the procedure. Coronary angiog...

Percutaneous transluminal coronary angioplasty (PTCA) of angulated stenoses has been found in studies using older PTCA equipment to be associated with a heightened risk of procedure-related major ischemic events. To better understand the factors associated with procedural risk and to identify means of lessening that risk, 100 patients, treated sequentially from 1986 to 1989, who underwent PTCA ...
