Hemodynamics of left ventricular assist device implantation

Le résumé fourni par la source

The modern history of left ventricular (LV) assist devices (LVAD) dates back to the late 1970s and early 1980s with the development of the Jarvik artificial heart. There are multiple factors that should be considered when assessing a patient's eligibility for LVAD. It is critical to evaluate not only their expected tolerability of the initial operative insult but also the likelihood that the patient will reap durable benefits from mechanical support. The ideal LVAD patient has predominantly advanced LV dysfunction. These individuals will have elevated left-sided cardiac filling pressures, and often secondarily increased right-sided filling pressures. When present, cardiac tamponade can result in hemodynamics characterized by a rise in and equalization of diastolic pressures. Hemodynamic assessment will continue to be a pivotal tool for guiding appropriate patient selection, assisting with patient management, and monitoring for potential sequelae of LVAD therapy.
