Percutaneous Transluminal Coronary Angioscopy

Percutaneous Transluminal Angioscopy During Coronary Intervention

To investigate the feasibility of angioscopic-guided percutaneous transluminal coronary angioplasty and to elucidate the mechanism of efficacy of coronary stenting for acute myocardial infarction, we performed coronary angioscopy in 102 patients with stable angina or acute myocardial infarction. Thrombi and intimal flaps were observed in most patients after coronary angioplasty. Large intimal s...

Percutaneous coronary angioscopy.

Morphologic changes in the coronary arteries of patients with ischemic heart disease were evaluated by angiography. Although a powerful diagnostic tool, angiography can show only the shadow of the luminal changes and therefore is an insufficient tool for diagnosis of pathological changes. Recent advances in fi beroptic technology now enable observation of the luminal changes even in small diame...

Percutaneous transluminal coronary angioplasty.

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...
