CPT® Code 33322

The procedure described by CPT® Code 33322 involves the suture repair of the aorta or great vessels, which are critical components of the cardiovascular system. This surgical intervention is performed with the use of cardiopulmonary bypass, a technique that temporarily takes over the function of the heart and lungs during surgery. The access to the heart is achieved by opening the sternum or chest wall, allowing the surgeon to directly visualize and repair the damaged area. During the procedure, the heart continues to beat, and the surgeon meticulously sutures the affected aorta or great vessel to restore its integrity. Following the completion of the repair, the cardiopulmonary bypass is discontinued, and the chest is subsequently closed. This procedure is essential for addressing significant vascular injuries or defects that could compromise blood flow and overall cardiovascular health.
