CPT® Code 33675

A ventricular septal defect (VSD) is a congenital heart defect characterized by one or more abnormal openings in the septum that separates the heart's ventricles. This condition can lead to significant hemodynamic changes and requires surgical intervention for correction. The procedure associated with CPT® Code 33675 involves the closure of multiple VSDs through a surgical approach that typically requires an incision in the chest to access the heart. During the operation, the pericardium, which is the fibrous sac surrounding the heart, is incised, and a patch may be harvested if necessary for the repair. Cardiopulmonary bypass is initiated to maintain circulation and oxygenation while the heart is being operated on. The multiple VSDs are repaired through an incision made in the right atrium, pulmonary artery, or the outflow tract of the right ventricle, known as the infundibulum. The defects can be closed using sutures or by placing a patch over the openings. If a patch is utilized, it may consist of synthetic material or a previously harvested piece of pericardium, which is sutured securely over the defects to restore normal heart function. After the repairs are completed, the access incision is closed, and cardiopulmonary bypass is discontinued. Chest tubes are then placed to facilitate drainage, and the chest incision is finally closed, marking the completion of the procedure.
