Popis: To evaluate the utility of a three-dimensional printed model (3D-model) for surgical decision planning in a complex case of multiple ventricular septal defect (VSD) (so-called Swiss-cheese septum). A 3 month-old-girl with diagnosis of multiple apical VSDs in the trabecular septum, perimembranous VSD, and atrial septal defect that resulted in congestive heart failure was referred for surgical intervention. Due to inconclusive understanding of the total number, openings and locations of the apical VSDs, there were concerns regarding the best surgical approach. Using computed tomography images, a 3D-model was fabricated by fused deposition modeling of polyurethane filament. The 3D model helped identifying the total number of VSD, their origins and exits as well as the minimum number of septal bands to resect, the optimal patch size and morphology to completely close all VSDs without reducing significantly the RV cavity. The procedure was successfully replicated in the patient by right atrial approach, resulting in good RV cavity size, function and no residual VSDs evaluated by transesophageal echocardiography. Direct evaluation of the 3D printed replica anatomy and surgical simulation may help optimizing surgical approach, patch size and location and therefore it might reduce complications and residual defects.
