Anomalous origin of left main cononary artery from anterior sinus of Valsalva with myocardial infarction
DA Murphy, DL Roy, M Sohal and BM Chandler
The origin of the left main coronary artery, or its branches, from the
right or anterior sinus of Valsalva is a recognized congenital anomaly. The
origin of the entire left main coronary artery from a separate ostium in
the right sinus of Valsalva and its course to the right and behind the
ascending aorta, in a living patient without associated congenital heart
disease, has not been described. This anomaly was recognized as the cause
of an anterior myocardial infarction in a 12- year-old girl, and it is the
subject of this case report.
