Abstract:

Anomalous Origin of The Left Coronary Artery from The Pulmonary Artery (ALCAPA), also known as Bland-White-Garland syndrome, is a rare and potentially lethal congenital heart disease. Although it is typically diagnosed during infancy, the presence of collateral circulation between the right and left coronary arteries may allow survival into adulthood. We report the case of a 36-yearold woman with late-diagnosed ALCAPA following hemodynamic decompensation in the postgestational period, despite preserved ventricular function. This case highlights the importance of recognizing this anomaly in adults presenting with atypical ischemic symptoms and underscores the need for early surgical correction to prevent fatal outcomes.
