Percutaneous transluminal angioplasty of coronary arteries with anomalous origin.

Coronary angioplasty to diseased anomalous coronary arteries is being more readily applied in revascularization of these vessels. Several cases of angioplasty have been described in various coronary anomalies. Probably more attempts of PTCA to anomalous coronary arteries are performed but not reported. For this reason, we cannot assume that the success rate is the same as in "normal" origin arteries or which complications occurred, including the need for coronary bypass. Although not yet reported, in some instances other techniques, such as laser atherectomy and coronary stents, may be applied, provided the artery is not tortuous, as it may be in some anomalous coronaries. The key to a successful procedure depends on angiographic knowledge of their course and appropriate equipment selection.
