CPT® Code 33676

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 increased blood flow to the lungs and may result in heart failure if not addressed. The procedure associated with CPT® Code 33676 involves the surgical closure of multiple VSDs, along with the performance of a pulmonary valvotomy or infundibular resection, specifically in cases where there is an obstruction of the right ventricular outflow tract. This obstruction may occur in conjunction with conditions such as mild (acyanotic) tetralogy of Fallot. The surgical approach requires an incision in the chest to access the heart, followed by the incision of the pericardium. A patch may be harvested if necessary, and cardiopulmonary bypass is initiated to facilitate the procedure. The surgeon will then repair the VSDs through an incision in the right ventricle or pulmonary artery, excising any obstructive fibrous or muscular bands and inspecting the pulmonary valve for any fused commissures that may need to be opened. The closure of the VSDs is performed using sutures or patches, ensuring that the heart can function effectively post-surgery. This procedure is critical for improving the patient's quality of life and preventing further complications associated with untreated VSDs and right ventricular outflow tract obstruction.
