We report a case of transcatheter paravalvular leak (PVL) closure assisted by three-dimensional (3D) printing and intracardiac echocardiography (ICE) in a patient with complex valvular history. A 70-year-old male manifested acute exacerbation of dyspnea, accompanied by orthopnea and nocturnal paroxysmal respiratory distress. Echocardiographic evaluation revealed severe aortic PVL. After multidisciplinary heart team evaluation, transcatheter aortic PVL closure was selected as the preferred therapeutic strategy. The preoperative assessment of PVL location, size, and morphology using 3D printing technology accurately guided the interventional position and the selection of the occluder size and the successful completion of closed treatment under local anesthesia, which was assisted by intracardiac echocardiography to ensure the safety and smoothness of the procedure.
