Incidental Discovery of Anomalous Left Coronary Artery Arising from the Pulmonary Artery in a Coronavirus Disease-2019 Patient: A Blessing in Disguise

Anomalous origin of the left coronary artery from the pulmonary artery (ALCAPA) is a serious congenital malformation. Reports about asymptomatic, incidentally discovered ALCAPA in adults are scarce. We describe a patient with no known pre-existing cardiac condition admitted to our hospital with coronavirus disease 2019 (COVID-19) and was incidentally found to have ALCAPA. To the best of our knowledge, this is the first reported case of incidentally discovered ALCAPA in a COVID-19 patient and highlights the importance of appropriate investigation of the coronary status by Multidetector Cardiac Computed Tomographic Angiography (MDCCTA) in individuals with asymptomatic left ventricular dysfunction. The presentation of this case, discussion and literature review serves to iterate the necessity of appropriately investigating patients with asymptomatic LV dysfunction.
