Abstrakt: Hemodynamic alterations are a well-known phenomenon that influence the outcome of orthotopic liver transplantation (OLT). Whether or not myocardial dysfunction, which has various causes, contributes to this instability is still debated. Previous transesophageal echocardiography (TEE) studies have presented controversial data, not leading to final clarification. This is mainly because the impact of other contributing factors (inotropic support, alternating preload conditions and temperature) remained unaccounted for. We therefore measured the left ventricular shortening fraction (LVSF), a parameter reflecting myocardial contractility, in 10 consecutive patients undergoing OLT without veno-venous bypass. We measured during preparation (PP), during the anhepa tic (AP) phase and the immediate reperfusion phase (RP). During the AP we observed a significant decrease of LVSF which never fell to subnormal levels in the majority of our patients, whereas during the RP, LVSF returned to PP [ABSTRACT FROM AUTHOR]
