Patients with liver cirrhosis (LC) undergoing cardiac surgery (CS) face perioperative high mortality and morbidity, but extensive studies on this topic are lacking. All adult patients with LC undergoing a CS procedure between 2000 and 2017 at 10 Italian Institutions were included in this retrospective cohort study. LC was classified according to preoperative Child-Turcotte-Pugh (CTP) score and Model for End-Stage Liver Disease (MELD) score. Early-term and medium-term outcomes analysis was performed in the overall population and according to CTP classes. The study population included 144 patients (mean age 66 ± 9 years, 69% male). Ninety-eight, 20, and 26 patients were in CTP class A, in early CTP class B (MELD score <12), or advanced CTP class B (MELD score >12), respectively. The main LC etiologies were viral (43%) and alcoholic (36%). Liver-related clinical presentation (ascites, esophageal varices, and encephalopathy) and laboratory values (estimated glomerular filtration rate, serum albumin, and bilirubin, platelet count) significantly worsened across the CTP classes (P =.001). Coronary artery bypass grafting or valve surgery (87% bioprosthesis) were performed in 36% and 50%, respectively. Postoperative complications (especially acute kidney injury, liver complication, and length of stay) significantly worsened in advanced CTP class B (P =.001). Notably, observed mortality was 3-fold or 4-fold higher than the EuroSCORE (European System for Cardiac Operative Risk Evaluation) II–predicted mortality, in the overall population, and in the subgroups. At Kaplan-Meier analysis, 1-year and 5-year cumulative survival in the overall population was 82% ± 3% and 77% ± 4%, respectively. The 5-year survival in CTP class A, early CTP class B, and advanced CTP class B was 72% ± 5%, 68% ± 11%, and 61% ± 10%, respectively (P =.238). CS outcomes in patients with LC are significantly affected in relation to the extent of preoperative liver dysfunction, but in early CTP classes, medium-term survival is acceptable. Further analysis are needed to better estimate the preoperative risk stratification of these patients. [Display omitted] [ABSTRACT FROM AUTHOR] |
