Anomalous course of coronary artery challenging mitral valve surgery

Abstract

Suture-related injuries of the left circumflex branch are a serious and well-known complication of mitral valve surgery. Avoiding this complication is challenging, especially in an unexpected course of coronary arteries. We present a case of minimally invasive mitral valve repair in a patient with a rare anatomical variant of the main stem in direct proximity to the whole anterior leaflet.anomalous, coronary artery, mitral valve surgery
