Background: Adverse cardiovascular events after liver transplantation (LT) are relatively common and are a significant source of early mortality. Although new-onset systolic dysfunction after LT is a reported phenomenon, there is little data regarding its incidence, risk factors, and outcomes. Methods and Results: This single-center retrospective study included all adult patients from January 2002 to March 2015 with deceased-donor LT and available preoperative transthoracic echocardiograms (TTEs). In total, 1,760 patients were included in the study, 602 (34.2%) of whom had a postoperative TTE. The primary end point was development of new-onset cardiomyopathy, defined as a new left ventricular ejection fraction (LVEF) of <40% within 180days of transplant. Sixty-nine (11.4%) of the patients who received post-LT TTE had a reduction in LVEF to <40% within 6 months. Clinical parameters of donor and recipient did not show significant impact on development of post-LT LV systolic dysfunction (LVSD). Presence of wall motion abnormalities (P =.004) on preoperative TTE was predictive of development of post-LT LVSD. These patients did not have longer hospitalizations, but they had worse survival. Conclusions: Post-LT LV systolic dysfunction occurs at higher rates than previously suspected and may develop more frequently in patients with underlying cardiac structural abnormalities, which appear to adversely affect post-LT survival.
