Coronary arteriovenous fistula draining into single left superior vena cava
摘要
A 35-year-old female presented with heart failure. She was evaluated and found to have persistent left superior vena cava, no right superior vena cava (RSVC), coronary arteriovenous fistula into left-sided superior vena cava (LSVC) with left-to-right (L-R) shunt. She underwent closure of fistula using cardiopulmonary bypass and antegrade and retrograde cardioplegia. After opening the distal left circumflex, a coronary probe was passed through the fistula to delineate the course. The fistula was closed from both ends using a pericardial patch. This is a very rare anomaly with a single SVC.
