3D in Congenital Heart Disease: Double Outlet Right Ventricle
Dr. Pedro Becker Rencoret
Hospital Clínico UC Christus - Santiago de Chile, Chile
✔ Increased understanding of anatomy
✔ Design of the surgical plan
✔ Improved interaction between the physician and the patient's family
✔ Improved interaction between the physicians involved
Approximately 3-month-old infant with double outlet right ventricular, a Congenital Heart Disease.
In addition to the anomalous outflow and interventricular connection, the patient has a right pulmonary artery stenosis.

Surgical plan and results in operating room
In order to understand the complex anatomy of the heart and to plan the procedure to be performed, the heart was segmented and 3 models were printed with different views of the model. A first model corresponds to the visualisation of the blood pool; a second model, with a septal view of the endocardial surface and finally, the third model, which corresponds to a basal view of the endocardial surface. The views showed the anatomy of the interventricular septum and its discontinuity, the outflow and inflow tracts of the ventricles, especially the anomalous outflow.
The 3D model made it possible to easily assess the relationship of the interventricular connection to the conal septum and to the ventriculo-infundibular fold.
