Percutaneous Coronary Intervention for Coronary Arteries with Origin and Course Anomalies: Case Reports and Literature Review

Abstract

Coronary artery anomalies (CAAs) are defined as variants of normal epicardial coronary arteries. They are mostly detected incidentally during coronary angiography. Clinical studies have shown that abnormal origins and courses of coronary arteries make them more prone to atherosclerosis. Percutaneous treatment for atherosclerotic occlusions in anomalous coronary arteries has some difficulties, including inadequate guiding-catheter support and the need for an experienced operator. Here, we describe successful percutaneous coronary interventions for critical stenoses in 2 different CAAs and present a brief literature review.
