Periprocedural thrombus formation is not only responsible for one of the most serious complications of percutaneous transluminal coronary angioplasty, acute thrombotic occlusion of the coronary artery, but has also been postulated as the initial trigger of pathophysiological mechanisms leading to restenosis. The latter hypothesis is based on experimental findings showing that thrombin activatio...

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...

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...

Inappropriate percutaneous transluminal coronary angioplasty of the anterior descending artery was avoided in a 52-year-old woman when the intracoronary administration of glyceryl trinitrate immediately before the angioplasty disclosed the organic component of the supposedly fixed, critical (80%) stenosis to be less than 50% of the lumen diameter. The spastic component of the stenosis had not b...

In two patients percutaneous transluminal coronary angioplasty was complicated by coronary perforation. In both cases the complication was managed conservatively.

Percutaneous transluminal coronary angioplasty (PTCA) is a nonoperative mechanical dilatation of atherosclerotic coronary artery stenosis by a balloon-tipped dilating catheter system. This method can effectively reduce highly stenotic coronary lesions and provide early recovery of ischemic but viable myocardium. The technique of transluminal angioplasty was originally devised by Dotter and Judk...

introduction: percutaneous transluminal coronary angioplasty (ptca) is an effective method for revascularizing of stenotic coronary vessels. lack of response to this treatment, either in symptomatic or asymptomatic patients, is usually due to incomplete revascularization, restenosis, and/or irreversibility of myocardial perfusion. introduction of a noninvasive method with high predictive value ...

Background: The number of interventional cardiology (IC) procedures has increased rapidly. coronary angiography (CA) and percutaneous transluminal coronary angioplasty (PTCA) are now widely performed as a matter of routine, and they are considered safe procedures for experienced cardiologists. However, it is also known that these procedures are associated with high radiation doses due to long f...
