Novel Repair for Obstructed Total Anomalous Pulmonary Venous Connection to Coronary Sinus

A 4-month-old infant underwent surgery for total anomalous pulmonary venous connection to the coronary sinus with obstructions both at the entry of the common chamber into the coronary sinus and at the patent foramen ovale. Using a novel technique, the right atrium was opened with a transverse incision. The coronary sinus was de-roofed. The coronary sinus–common chamber junction was split open into the common chamber. The incision extended up to the drainage of the right-sided pulmonary veins into the venous chamber. The common chamber was then anastomosed to left atrium thereby establishing an unobstructed pathway. The atrial septal defect was closed with a pericardial patch.
