Prenatal Diagnosis and Neonatal Surgical Management of a Giant Proximal Right Coronary Artery to Right Ventricular Fistula

We report a case of prenatal diagnosis and early neonatal surgical repair of a large proximal right coronary artery to right ventricular fistula. The surgical findings and technical details of the reparative operation are discussed in the context of the differential diagnosis, which, in addition to coronary-cameral fistula, also includes aortoventricular tunnel and ruptured sinus of Valsalva aneurysm. Timely and appropriate diagnosis and surgical management resulted in preserved patency of the right coronary artery and restoration of normal right ventricular function.
