[Intensive care treatment of patients with left ventricular assist devices].

Abstract

Apart from heart transplantation, implantation of a left ventricular assist device (LVAD) is the only established surgical treatment for therapy-refractory terminal left heart failure, The specific intensive care unit (ICU) management of these patients depends on the reason for the ICU admission and requires understanding of the characteristic hemodynamics of non-pulsatile LVADs as well as of the inherent problems. Knowledge about the specific features in hemodynamic monitoring, understanding of pump characteristics, management of anticoagulation and hemostasis and the handling of problems, such as right heart failure, aortic valve insufficiency and infections is essential. The management of unconscious LVAD patients can be challenging. It requires a sophisticated transthoracic and transesophageal echocardiography (TTE/TEE) examination, targeted laboratory diagnostics and consideration of possible alternative diagnoses. Professional interdisciplinary cooperation and exchange of current knowledge is crucial.
