The primary anomalies of coronary artery origin and course: A coronary angiographic analysis of 16,573 patients.

Abstract

The most frequent anomaly observed in the present study was related to the Cx artery, which is consistent with previous reports. Although coronary artery anomalies are rare, they may cause difficulties during coronary interventions or cardiac surgery and may occasionally result in sudden cardiac death. Therefore, the recognition and diagnosis of these anomalies is important and requires specialization in coronary angiographic techniques and other imaging modalities.
