Anomalous origin of the right coronary artery from the left sinus of Valsalva.
A 1-month-old boy without precedent clinical signs of heart disease died unexpectedly. At autopsy, the child was found to have origin of the right coronary artery from the left sinus of Valsalva immediately leftward to the thickening of the aortic wall at the cuspal commissure and adjacent to the ostium of the left main coronary artery. The association of this coronary anomaly with otherwise unexplained prenatal or early postnatal death has only recently been appreciated as a potential cause of sudden infant death and mimic of sepsis, dysrhythmias, congestive heart failure, or metabolic storage diseases.
