Percutaneous Transluminal Laser Angioplasty: Clinical Results

Conventional angioplasty versus percutaneous transluminal laser angioplasty.

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 angioplasty.

IN 1963 Dr Charles Dotter, a radiologist of Portland, Oregon whilst performing an aortogram by retrograde catheterisation of the right iliac artery inadvertently passed his guide wire, and then a catheter, through a complete occlusion of the artery. There was a palpable though diminished femoral pulse in the groin and the catheter was passed easily. It was only when radiographs were taken that ...

[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...
