Enhancing management of double outlet right ventricle when the interventricular communication is remote from the...

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.

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.

These cases underscore 3D printing's role in improving precision, reducing complications, and potentially lowering costs in managing complex congenital heart disease.
