Coronary Artery Fistula

Pathology presented herein is a rare congenital heart defect characterized by double outlet right ventricle, ventricular septal defect, and pulmonary atresia. The condition presents complex anatomical challenges, requiring precise surgical planning to restore normal cardiac function. The model illustrates the detailed spatial relationships within the heart, including the position of the ventricular septal defect relative to the aorta, which originates from the right ventricle. A virtual patch reconstruction demonstrates the creation of a blood flow pathway from the left ventricle through a tunnel formed by the patch to the aorta. The volumes of the right and left ventricles are segmented, allowing objective assessment. Additionally, the volume of the right ventricle without the tunnel connecting it to the aorta is evaluated. Since this volume matches the left ventricular volume, the operation can be performed safely without the risk of an undersized right ventricle post-surgery.

The model is composed of nine .STL files corresponding to each anatomical structure of the heart and its vessels. The structures are small, up to 19 MB for left ventricle. Printing each structure is suitable even for smaller 3D printers. We do recommend to print each structure by different color and then glue it together to make a great model for demonstrating the very rare pathology
