Reconstruction of Right Ventricular Outflow Tract (RVOT) may necessitate placing a conduit that establishes the continuity between the Right Ventricle (RV) and the Pulmonary Artery (PA). In addition to this method of reconstruction, some surgeons prefer direct RVPA connection to avoid conduit-related complications. Compression of a coronary artery caused by a RV-PA conduit is a rare but serious complication. It has been described in a few reports in the literature. We here are reporting two cases of this complication.
