Single Coronary Artery: Right Coronary Artery Originated From Middle of Left Anterior Descending Artery in a Patient With Severe Mitral Regurgitation

摘要

The single coronary artery is a benign and very rare coronary artery abnormality. Anomalous origin of the right coronary artery originating from the left anterior descending artery has been reported previously in just a few cases. In this article, we presented a patient with an anomalous origin of the right coronary artery from the midportion of the left anterior descending artery. The anomalous coronary artery was discovered incidentally during a coronary angiography performed prior to mitral valve surgery. Copyright ? 2010 Wiley Periodicals, Inc.
