CPT® Code 33970

The procedure described by CPT® Code 33970 involves the insertion of an intra-aortic balloon assist device (IABP) through the femoral artery using an open surgical approach. This procedure is typically performed to support patients with severe cardiac conditions, particularly those experiencing heart failure or undergoing high-risk cardiac surgeries. The IABP is designed to enhance coronary blood flow and improve cardiac output by inflating and deflating a balloon within the aorta in synchrony with the cardiac cycle. The inflation occurs during diastole, which increases blood flow to the coronary arteries, while deflation occurs during systole, assisting the heart in ejecting blood more efficiently. The procedure requires careful surgical techniques to expose the femoral artery, secure a vascular graft, and ensure proper placement of the balloon catheter within the descending aorta. This intervention is critical in managing patients with compromised cardiac function, as it can significantly reduce the workload on the heart and improve overall hemodynamic stability.
