Oiigen anomalo de la arteria coronaiia derecha de la arteiia pulmonar en un lactante con soplo cardiaco: A proposito de un caso / Anomalous origin of the right coronary artery from the pulmonary artery in an infant with a heart murmur: Case report

El origen anómalo de la arteria coronaria derecha de la arteria pulmonar es una entidad rara con una incidencia del 0,002 % y potencialmente grave, que puede causar muerte súbita. El diagnóstico frecuentemente es incidental, secundario a evaluaciones por soplos cardíacos a diferencia del origen anómalo de la arteria coronaria izquierda de la arteria pulmonar, reconocido por presentar isquemia miocárdica e insuficiencia cardíaca. Se reporta el caso de una niña de 6 meses evaluada por un soplo y derivada por sospecha de fístula coronaria. La evaluación mediante ecocardiograma doppler color, cateterismo cardíaco y angiotomografía mostró la presencia de una comunicación interauricular ostium secundum pequeña y origen anómalo de la arteria coronaria derecha de la arteria pulmonar. A los 11 meses, se realizó una cirugía de reimplante de la arteria coronaria derecha en la arteria aorta y el cierre de la comunicación interauricular.

The anomalous origin of the right coronary artery from the pulmonary artery (ARCAPA) is a rare entity that has an incidence of 0.002 % and can potentially cause sudden death. Unlike to the anomalous origin of the left coronary artery from the pulmonary artery (ALCAPA), usually presented with myocardial ischemia and heart failure; the diagnosis of ARCAPA is often incidental during evaluation of a heart murmur. We report a case of a 6 months old female patient referred to us with a cardiac murmur and a suspicion of coronary fistula. For a proper diagnostic assessment an echocardiogram, a computed tomography angiography and a cardiac catheterization were requested. A small ostium secundum-type atrial septal defect (ASD) and an ARCAPA were revealed. At 11 months old, the patient was scheduled for corrective cardiovascular surgery. The aim of this report is to describe a low incidence and potentially fatal disease.

Anomalous Origin of the Right Coronary Artery from the Pulmonary Artery / 대한흉부외과학회지

Anomalous origin of the right coronary artery from the pulmonary artery is a rare congenital anomaly that has generally been found incidentally during autopsy or surgery. Sudden death may occur without antecedent symptoms in apparently healthy, asymptomatic patients and hence operation is recommended when the lesion is recognized. As opposed to the more frequent anomalous origin of the left coronary artery from the pulmonary artery, only a few children with this anomaly have been reported to have undergone surgical treatment. This report describes a 2-year old patient whose diagnosis was made by echocardiography, confirmed by angiocardiography, and successfully corrected by reimplantation of the anomalous coronary artery into the aorta.
