The frequency of advanced cardiopulmonary imaging has increased the incidence of diagnosis of coronary artery anomalies, but this poses an interesting management dilemma of what to do with them once these anomalies are found. We present the case of a 57-year-old female with a past medical history of postpartum cardiomyopathy, recovered heart failure with reduced ejection fraction (EF), and alcohol use disorder who presented with chest pain, shortness of breath, nausea, vomiting, and palpitations. A CT angiogram was performed to rule out pulmonary embolism. No pulmonary embolism was found; however, the CT scan revealed an anomalous right coronary artery originating from the left coronary cusp, which had a malignant interarterial course (ARCA-LCC-IA) with a right dominant pattern of myocardial circulation. Subsequent nuclear stress testing did not show evidence of ischemia. Echocardiogram revealed a recurrently reduced EF of 40%. Our patient poses a management dilemma since she presented with possible angina and was found to have an anomalous right coronary artery (ARCA) with a malignant course, but subsequently she had a negative exercise stress test with nuclear perfusion imaging. We will review the literature on ARCA-LCC-IA and its clinical manifestations both generally and with its connection to this case as well as its management. We discuss the incidence, diagnosis, and management of ARCA-LCC-IA, with a focus on incidentally found lesions.
