Cardiac arrest due to aberrant left coronary artery originating from the right sinus of Valsalva in a young girl.

We report a 14-year-old girl who sustained a syncope followed by cardiac arrest. She was kept alive for three days by full cardiocirculatory support using left and right ventricular assist devices, but subsequently died in multiple organ failure. Autopsy revealed an anomalous origin of the left coronary artery (LCA) from the right sinus of Valsalva (RSV) and a major left anterior wall infarction. A cyclo-ergometric stress test performed two years before having been negative, we discuss its value in preventing sudden death due to coronary anomalies.
