Enhancing management of double outlet right ventricle when the interventricular communication is remote from the arterial roots through three-dimensional printing

Abstract

Abstract Background Double outlet right ventricle with remote interventricular communication presents significant surgical challenges. Traditional imaging often fails to provide the detailed, three-dimensional anatomical insights required for complex cases. Advancements in three-dimensional (3D) printing offer a valuable tool for preoperative planning and decision-making. Cases In the first case, a 5-year-old with double outlet right ventricle and remote interventricular communication underwent a Glenn procedure with anticipated univentricular repair. 3D printing revealed the potential for enlarging the communication, leading to a one-and-a-half ventricle repair. The second case involved a 2-day-old infant with double outlet right ventricle, aortic arch interruption, and remote communication. At one year, 3D modelling enabled a successful left ventricle-to-aorta baffle. Conclusion These cases underscore 3D printing’s role in improving precision, reducing complications, and potentially lowering costs in managing complex congenital heart disease.
