[Sudden death due to an anomalous origin of the left anterior descending coronary artery from the pulmonary trunk in a 9-year-old boy].
A 9-year-old healthy boy is presented, who complained of dizziness and to being exhausted after climbing numerous stairs, collapsing immediately after. Advanced resuscitation efforts were unsuccessful. At autopsy an isolated congenital anomaly in the origin of the left anterior descending coronary artery from the pulmonary trunk was found, with the origin of the right and left circumflex coronary arteries from the aorta, accompanied by with cardiac hypertrophy and chronic ischemic changes in the myocardium irrigated by the anterior descending artery. This represents a very infrequent variant that allows a longer survival and less functional repercussion if compared with those cases in which the main left coronary is originated from the pulmonary trunk.
