Abstract

OBJECTIVE:

Left ventricular diastolic dysfunction is receiving more attention in patients with end-stage liver diseases. The importance of diastolic dysfunction observed before orthotopic liver transplantation (OLT) and its adverse effects on hemodynamics and outcomes of OLT patients, have not been fully explored. We carried a retrospective study to investigate the influence of diastolic dysfunction on OLT patients.

METHODS:

Included in this retrospective study were 330 consecutive patients scheduled for cadaveric OLT over a 5-year period. According to preoperative Doppler echocardiogram (ECHO) findings, patients were divided into two groups: DD group (patients with diastolic dysfunction) and control group (patients with normal ECHO). Patient characteristics, operation variables, hemodynamic course, blood products and drug requirements, postoperative courses and outcomes were evaluated.

RESULTS:

306 patients met the study entry criteria and 100 had preoperative diastolic dysfunction. Mean artery blood pressure was significantly lower in DD group after graft reperfusion than that in control group (P<0.01). More patients in DD group required epinephrine, and the mean dose of epinephrine was higher in DD group than that in control group (P<0.01). There was no significant difference in postoperative ventilation time, duration of ICU and hospital stay, renal failure and postoperative mortality between the two groups.

CONCLUSION:

Diastolic dysfunction is common in liver transplant recipients. Patients with diastolic dysfunction may be associated with substantial hemodynamic alterations after graft reperfusion and need more inotropic support during OLT. Diastolic dysfunction was not associated with significant adverse postoperative outcomes.
