ABSTRACT
Third coronary artery or supernumerary coronary artery is a direct branch from right aortic sinus and it supplies pulmonary conus and upper part of right ventricle. Third coronary artery is an important bridge for collateral circulation between right and left coronary system. The aim of this study was to determine the number of arteries that origin from right aortic sinus, their frequency and position. The study included 55 adult human hearts collected from Department of Anatomy. The hearts were morphologically studied by gross dissection for the prevalence and topographical anatomy of supernumerary coronary arteries. Out of 55 hearts, 26 (47.3 %) had one right coronary artery, 23 (41.8 %) had two right coronary arteries, and 6 (10.9 %) had three coronary arteries. The supernumerary arteries arises from the right aortic sinus. Right supernumerary coronary arteries may be present in about 52.7 % of the Serbian population. Interpretation of signs and symptoms of coronary occlusion should therefore consider possible contribution of this blood vessels.
RESUMEN
La tercera arteria coronaria o arteria coronaria supernumeraria es una rama directa del seno aórtico derecho y su ministra el cono pulmonar y la parte superior del ventrículo derecho. La tercera arteria coronaria es importante para la circulación colateral entre el sistema coronario derecho e izquierdo. El objetivo de este estudio fue determinar el número de arterias de origen del seno aórtico derecho, su frecuencia y posición. El estudio incluyó 55 corazones humanos adultos pertenecientes al Departamento de Anatomía. Los corazones se estudiaron morfológicamente mediante disección macroscópica para determinar la prevalencia y la anatomía topográfica de las arterias coronarias supernumerarias. De 55 corazones, 26 (47,3 %) tenían una arteria coronaria derecha, 23 (41,8 %) tenían dos arterias coronarias derechas, y 6 (10,9 %) tenían tres arterias coronarias. Las arterias supernumerarias surgen del seno aórtico derecho. Las arterias coronarias supernumerarias derechas pueden estar presentes en aproximadamente el 52,7 % de la población serbia. La interpretación de los signos y síntomas de la oclusión coronaria debería considerar la posible contribución de estos vasos sanguíneos.
