Three-Dimensional Cardiac Imaging: A Necessity to the Diagnosis and Treatment of Swiss-Cheese Atrial Septal Defect

Swiss-cheese atrial septal defect (ASD) is a malformation characterized by multi-fenestrated interatrial defects. Here, we describe vignette of 23-year-old man with Swiss-Cheese ASD two defects areas 0.74 cm2 and 0.44 cm2, complicated an aneurysm successfully repaired cribriform amplatzer occluder (ASO) via the percutaneous transcatheter approach. This case emphasizes importance attaining clear view three-dimensional structures for proper device selection deployment in repair as additional structural such concomitant aneurysms impose significant challenges.
