✦ Synopsis

Left-sided heart failure (LHF) after liver transplantation (LT) is rare and poorly understood. We performed a case-control study. We reviewed the data of all patients with LHF after LT at our center from November 2000 to July 2007. Each case was matched to 1 LT control without LHF for age, sex, date of transplantation, and liver disease. Twenty of 599 patients developed LHF (3.3%). Pretransplant cardiovascular characteristics and risk factors were similar in cases and controls, except for the prevalence of left ventricular enlargement, which was greater in controls. At the time of diagnosis, the median left ventricular ejection fraction was 25% in cases, and increased afterload was documented by markedly elevated vascular resistances. The prevalence of infection at the time of LHF in cases was higher (55%) than in controls (10%, P ϭ 0.02). The reported causes of LHF were infection [bacterial (n ϭ 1) or viral (n ϭ 7)], intraoperative cardiac arrest (n ϭ 2), and unknown (n ϭ 10). In comparison with their controls, cases with immediate postoperative LHF (day 0) did not have a higher Model for End-Stage Liver Disease (MELD) score (15 versus 21.5) or infection prevalence rate (17% versus 34%), whereas those with later onset LHF had a significantly higher MELD score (25.5 versus 17, P ϭ 0.01) and infection prevalence rate (71% versus 0%, P ϭ 0.002). Mortality was 45% in cases versus 0% in controls (P ϭ 0.004), and the 11 cases who survived recovered from LHF. In conclusion, LHF after LT carries a high mortality risk and may have different causes. Except for immediate postoperative cases, an infection and an elevated MELD score appear to be determinant.
