Abstract
Four cases of successful coronary angioplasty for anomalous coronary arteries, including dextrocardia associated with three-vessel disease, single left coronary artery with proximal left anterior descending lesion, anomalous right coronary artery (RCA) from adjacent left coronary sinus of Valsalva associated with proximal RCA lesion, and anomalous left circumflex angulated lesion bifurcated from the RCA, were encountered. Four cases with 8 target lesions who had a mean age of 63.5 ±11.5 years old are presented. All the targets lesions were completely dilated through balloon angioplasty, including use of a newly developed support device for cases with large jeopardized myocardium. The factors for complete revascularization were appropriate selection of catheters and originality and ingenuity of procedural technique based on the anatomic characteristics.
