Pathological changes induced by repeated percutaneous transluminal coronary angioplasty.

Pathological changes induced by repeated percutaneous transluminal coronary angioplasty.

The histopathological appearances of seven coronary arteries obtained from four patients after repeated percutaneous transluminal coronary angioplasty were analysed. A complex picture was found; typically there were ruptured atherosclerotic plaques, plaque dissection, and a fibrous tissue response. The histopathological appearance of older and more recent fibrous lesions was different. Older le...

Pathological findings after percutaneous transluminal coronary angioplasty.

Ten serial pathological cross sections at 1 mm intervals of both the left anterior descending artery at the site of a percutaneous transluminal coronary angioplasty and of the circumflex artery in the untreated stenotic area were studied at necropsy in a patient who died immediately after the procedure. The extent of calcification and atheroma were similar in both branches. Intimal or medial sp...

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...

Percutaneous transluminal coronary angioplasty.

[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...
