The procedure described by CPT® Code 33506 involves the surgical repair of an anomalous coronary artery that originates from the pulmonary artery. This condition can lead to significant cardiovascular complications, as the anomalous artery may not supply adequate blood flow to the heart muscle. The surgical intervention entails a translocation of the anomalous coronary artery from its abnormal origin in the pulmonary artery to its proper position in the aorta. To access the heart, the surgeon performs a median sternotomy, which involves making an incision along the sternum to provide a clear view of the heart and surrounding structures. The procedure can be conducted using cardiopulmonary bypass, which temporarily takes over the function of the heart and lungs, or it may be performed on a beating heart using an off-pump technique, allowing for a more direct approach without the need for bypass. During the operation, the pericardium, the protective sac surrounding the heart, is incised, and a patch of pericardial tissue is harvested for later use. The surgeon then incises the pulmonary artery to excise the anomalous origin of the coronary artery, taking a button of pulmonary artery tissue along with it. The anomalous coronary artery is carefully mobilized, and an incision is made in the aorta to facilitate the anastomosis, or surgical connection, of the anomalous artery to the aorta using the harvested pulmonary artery button. After the connection is made, the defect in the pulmonary artery is repaired with the previously harvested pericardial patch. If cardiopulmonary bypass was utilized during the procedure, it is then discontinued. Finally, chest tubes may be placed as necessary to drain any fluid or air, and the chest is closed to complete the surgery.

The procedure described by CPT® Code 33506 is indicated for patients with an anomalous coronary artery that originates from the pulmonary artery. This condition can lead to various symptoms and complications, including:
The surgical procedure for CPT® Code 33506 involves several critical steps to ensure the successful repair of the anomalous coronary artery. The following outlines the procedural steps:
After the completion of the procedure, patients are typically monitored in a recovery area for any immediate complications. Post-operative care may include managing pain, monitoring vital signs, and ensuring proper heart function. Patients may require additional imaging or tests to assess the success of the repair. The length of recovery can vary based on individual patient factors and the complexity of the surgery, but patients are generally advised to follow up with their healthcare provider for ongoing assessment and management of their cardiovascular health.
