CPT® Code 33927

A total replacement heart system (also known as a total artificial heart or TAH) is a sophisticated mechanical device designed to replace both ventricles of the heart. This system utilizes polyurethane structures and disc valves, which are connected to an external pumping drive, to mimic the function of a natural heart. The primary purpose of a TAH is to provide temporary support for patients with severe heart failure, acting as a bridge until a suitable donor heart becomes available for transplantation. The procedure for implantation of a TAH, identified by CPT® code 33927, involves a surgical technique known as recipient cardiectomy, which entails the complete removal of the patient's failing heart. The surgical approach typically begins with a median sternotomy, allowing access to the thoracic cavity. Following the creation of a peritoneal pocket in the abdomen for the external components of the device, a series of precise incisions and dissections are performed to facilitate the connection of the TAH to the patient's vascular system. This complex procedure requires meticulous attention to detail to ensure proper placement and function of the artificial heart, as well as to minimize complications during and after surgery.
