SAAVEDRA, Melina J et al. Anomalous origin of the right coronary artery from the pulmonary artery in an infant with a heart murmur: Case report. Arch. argent. pediatr. [online]. 2018, vol.116, n.6, pp.e789-e792. ISSN 0325-0075.  http://dx.doi.org/10.5546/aap.2018.e789.

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.
