Uncommon Anomaly and Uncommon Errors: Anomalous Left Coronary Artery from the Pulmonary Artery (ALCAPA) in 60 year Old Women

Anomalous origin of the left coronary artery from the pulmonary artery (ALCAPA) is rare congenital cardiac anomaly which results high mortality during infantile period and only 10% to 15% of the individuals with this defect reach adulthood.We describe a 60 yearold women case with ALCAPA who was misdiagnosed with LM occlusion that lead to unnecessary coronary artery bypass grafting (CABG).After surgery a patient's symptoms deteriorated until visit at our clinic definitive diagnosis was not estabilished.This clinical case highlights the importance of recognizing the risks of misdiagnosis, which can lead to life-threatening conditions.Invasive coronary angiography (ICA) was the standard for ALCAPA diagnosis as it depicted the course of the anomalous coronary artery; however, it has been largely replaced by noninvasive diagnostic testing.Thorough examination is essential, particularly when atypical alterations in the vascular bed are identified.
