Summary:We report a case of variant origin of the right coronary artery from the left posterior aortic sinus. This was observed routinely during a medico legal autopsy of a 58 year old male who died in a road traffic accident. Initially it was believed that the right coronary artery was absent since there was no obvious right coronary artery ostium from the anterior aortic sinus. However it was found later that the right coronary ostium was present just beside the left coronary ostium in the left posterior aortic sinus and the right coronary artery was arising from the left posterior aortic sinus. The right coronary artery had an intramural course between the aorta and pulmonary trunk, which is considered as very dangerous and life threatening. We believe that the present case report will be enlightening to the cardiologist and cardiothoracic surgeon. It is also true that the conduction of medico legal autopsies of coronary arteries is important for the medico legal resolution. KEY WORDS: Aortic Sinus; Coronary Artery Ostium; Right Coronary Artery; Left Coronary Artery. Se presenta un caso de variacion de origen de la arteria coronaria derecha desde el seno aortico posterior izquierdo. Esto se observo de forma rutinaria durante una autopsia medico-legal de un hombre de 58 anos que murio en un accidente de transito. Inicialmente se creia que la arteria coronaria derecha estaba ausente ya que no habia un ostium observable desde el seno aortico anterior. Sin embargo, se descubrio mas tarde que el ostium de la arteria coronaria derecha estaba presente justo al lado del ostium de la arteria coronaria izquierda en el seno aortico posterior izquierdo y la arteria coronaria derecha se originaba del seno aortico posterior izquierdo. La arteria coronaria derecha presento un recorrido intramural entre la aorta y el tronco pulmonar, que se considera como muy peligroso y potencialmente mortal. Creemos que el presente trabajo sera esclarecedor para el cardiologo y el cirujano cardiotoracico. Tambien consideramos que el conocimiento de la anatomia de las arterias coronarias es importante durante el desarrollo de la autopsia medico-legal para lograr alcanzar una correcta resolucion del proceso medicolegal. PALABRAS CLAVE: Seno aortico; Ostium de la Arteria Coronaria; Arteria coronaria derecha; Arteria coronaria izquierda.
