We present here a case of an infant who was prenatally diagnosed with an isolated left atrial appendage aneurysm. Although asymptomatic, we proceeded with surgical resection due to rapid progression of aneurysm size. Multimodality imaging – transthoracic echocardiography, transesophageal echocardiography, and cardiac computed tomography – was used for procedural planning, from which a detailed 3D computational model and 3D print of this patient’s heart were created. The aneurysmectomy was performed at 6 months of age, with an uneventful postoperative course.
