CPT® Code 33976

An extracorporeal ventricular assist device (VAD) is a mechanical device designed to support the heart's function by assisting in the pumping of blood. This procedure involves the insertion of a VAD into one or both of the heart's ventricles, which are the lower chambers responsible for pumping blood to the lungs and the rest of the body. The VAD consists of a mechanical pump, a control system, and an energy supply, all of which work together to facilitate blood circulation. Unlike implantable devices, an extracorporeal VAD operates externally, with pumps that are situated outside the body and connected to the heart via cannulas. VADs are primarily utilized in patients who are awaiting a heart transplant, providing crucial support during this waiting period. They are also employed to prolong the lives of patients suffering from severe heart failure, offering a temporary solution to maintain adequate blood flow. Additionally, VADs can be used post-operatively following heart surgery to aid in the recovery of one or both ventricles, ensuring that the heart can regain its function effectively. The procedure typically involves a median sternotomy, which is a surgical incision made along the sternum to access the heart. Cardiopulmonary bypass is initiated to maintain blood circulation and oxygenation during the surgery, allowing the surgical team to work on the heart safely. The insertion of the VAD is a complex process that requires careful manipulation and suturing to ensure proper placement and function of the device.
