Nonangiographically evident collateral flow during primary percutaneous transluminal coronary angioplasty favors contractile recovery

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...

Normalization of coronary flow reserve by percutaneous transluminal coronary angioplasty.

Fifteen patients undergoing routine follow-up angiography 5 months after successful percutaneous transluminal coronary angioplasty (PTCA) without angina and with normal exercise thallium scintigraphy were selected for analysis. The coronary flow reserves of these patients were compared with those of 24 patients with angiographically normal coronary arteries to establish whether PTCA can restore...

[Percutaneous transluminal coronary angioplasty (PTCA)].

In 1959, Dr. Mason Sones reported on selective coronary arteriography, a technique that quickly became the standard for precise diagnosis of coronary artery disease. In the early 1960s Drs. Dotter and Judkins introduced the original concept of using a catheter to dilate an atherosclerotic obstruction in a peripheral artery. Now, almost 2 decades later, the selective coronary catheter is being p...

Percutaneous Transluminal Coronary Angioplasty Registry

In 1,801 patients in the 1985-1986 Percutaneous Transluminal Coronary Angioplasty Registry, overall 1-year mortality was 3.2%, the 1-year myocardial infarction rate was 7.2%, and the l-year coronary artery bypass surgery rate was 13.2%. In the 78% of the cohort with all lesions successfully dilated and without major procedural complications (successful patients), the corresponding rates were 1....
