Multislice Computed Tomography Coronary Angiography Uncovers Complex Post-ASD Repair Anatomy

A 53-year-old male with a history of heart failure with reduced ejection fraction (HFrEF) and permanent atrial fibrillation, who underwent ostium secundum atrial septal defect (ASD) repair at age 9, underwent multislice computed tomography (CT) coronary angiography to assess for significant coronary stenosis. The calcium score of 2 indicated minimal plaque burden, with the most significant lesion located at the ostium of the LCX, measuring 15.5%. This resulted in a CAD-RADS classification of 1/P1/HRP.
