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 ventricles of the heart, which is particularly beneficial for patients experiencing severe heart failure or those awaiting a heart transplant. The VAD consists of several components, including 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 connected to the heart via cannulas. The procedure typically requires a median sternotomy to gain access to the heart, and cardiopulmonary bypass is initiated to maintain blood flow during the surgery. The insertion of a left VAD involves specific steps, such as placing a partial occluding clamp on the aorta, suturing an outflow graft, and carefully inserting the inflow cannula into the left ventricle. If a right VAD is necessary, similar techniques are employed, with adjustments made for the pulmonary artery and right ventricle. This procedure is critical for patients who need temporary support for their heart function, allowing for recovery or bridging to a more permanent solution, such as a heart transplant.
