Percutaneous transluminal coronary angioplasty of anomalous coronary arteries. Case reports.

To date, technical experience reported in the literature is very limited on angioplasty in patients with anomalous coronary arteries. Balloon angioplasty may be a more favorable approach for revascularization in these vessels. A major factor is selection of the guiding catheter. The authors report 4 patients with severe atherosclerotic lesions of anomalous coronary arteries who underwent coronary angioplasty of the anomalous vessel. Three patients had an anomalous circumflex artery and 1 had an anomalous right coronary artery. Angiographic and clinical success were achieved in 3 patients.
