Anomalous origin of the right coronary artery from the left sinus of Valsalva: report of two cases.
Anomalous origin of the right coronary artery (RCA) from the left sinus of Valsalva (LSV) is rare and has only recently been recognized as a cause of sudden cardiac death in otherwise healthy individuals. In this report, we describe two cases of anomalous origin of the RCA from the LSV. In the first case, a previously healthy 11-year-old girl died suddenly and unexpectedly. An autopsy revealed no abnormalities, except for anomalous origin of the RCA from the LSV. In the second case, a 21-year-old woman died by drowning in a bath, probably after an episode of syncope brought about by anomalous origin of the RCA from the LSV.
