We present the case of a young patient with Anomalous Origin of the Left Coronary Artery from the Pulmonary Artery ( ALCAPA) syndrome who underwent reconstructive surgery and multiple cardiac computed tomography angiography (cCTA) studies for pre-surgical evaluation and follow-up. Throughout patient’s clinical course, progressive implementation of radiation dose-saving techniques significantly lowered the radiation dose by 95%. This case highlights the capabilities of developing radiation protection strategies that drastically lower radiation exposure during cCTA.
