The main challenge is identifying all defects intraoperatively, without which residual defects are inevitable. Patient-specific three-dimensional (3D) printed models can help accurately demonstrate intracardiac anatomy. We present our experience using this technology to surgically close multiple muscular VSDs .<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>Data of all patients with multiple VSDs in whom a 3D-printed model was used to aid surgical planning between September 2021 and July 2023 was collected retrospectively. Our approach involved generating a 3D model from a preoperative computerized tomography scan for each patient, which was then used to precisely identify the location of the multiple VSDs and plan surgical intervention.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>Six patients underwent closure of multiple VSDs using a 3D model. The mean age at surgery was 3.5 years (SD \u00b1 2.8 years). Five (83.3%) patients had previously undergone pulmonary artery banding. The VSDs were approached through the right atrium in three (50%) and the right ventricle in three (50%) patients. Mean cardiopulmonary bypass and myocardial ischemia times were 185.2\u2005min (SD \u00b1 94.8\u2005min) and 147.5\u2005min (SD \u00b1 86\u2005min), respectively. There was no postoperative heart block or a hemodynamically significant residual VSD. All six patients had normal biventricular function at a median follow-up duration of 1.7 months (interquartile range: 1.2-7.4 months).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>3D printing to aid closure of multiple VSDs is safe, reliable, and reproducible.
