Double Outlet Right Ventricle in Tetralogy of Fallot

Double Outlet Right Ventricle (DORV) is a congenital heart defect where both the aorta and the pulmonary artery arise primarily from the right ventricle, instead of the aorta arising from the left ventricle as in normal anatomy. DORV is associated with Tetralogy of Fallot (TOF), it represents a more complex form of the defect, incorporating the features of TOF—such as ventricular septal defect (VSD), pulmonary stenosis, right ventricular hypertrophy, and an overriding aorta.

In this case, the large VSD becomes critical for blood flow to the left ventricle, allowing oxygenated blood to enter the circulation. However, the presence of pulmonary stenosis often results in cyanosis due to reduced blood flow to the lungs. Surgical repair for DORV with TOF typically involves rerouting blood flow to ensure oxygenation, addressing the pulmonary stenosis, and separating systemic and pulmonary circulations to optimize heart function.

The model is quite complex, it contains 12 structures. What makes this structure unique is that not only structures of tissues are presented, but also the volumes of ventricles were segmented, too. The size of the structure is up to 15,7 MB and thus they are suitable for smaller printers. However, use of resin printer would be nice to enhance details of structures.
