Abstract

Objective: Liver disease (LD) is considered a risk factor for inferior outcomes in general and cardiac surgery, yet current cardiac surgery risk estimators exclude LD, and literature on the topic remains scant. We sought to evaluate whether the presence of advanced LD is associated with inferior outcomes following cardiac surgery.

Methods: This single-center, retrospective, observational study included 285 patients diagnosed with LD who underwent cardiac surgery in 2010 to 2020. The cohort contained 3 groups, Child-Turcotte-Pugh (CTP) class A (n = 219), CTP early-class B (n = 34), and CTP advanced-class B (n = 32). A model for end-stage liver disease score of 12.7 points (determined using a receiver-operating characteristic curve analysis on 30-day mortality) dichotomized class B into early- and advanced-groups. Univariate and multivariate logistic regression analyses were performed to identify predictors of 30-day mortality.

Results: Patients in CTP advanced-class B had the longest length of stay (14 days), highest incidence of prolonged ventilation (46.9%), renal failure (21.9%), 30-day mortality (18.8%), and in-hospital mortality (18.8%). Incidence of ≥1 postoperative complication was higher in CTP advanced-class B (59.4%), compared with CTP class A (37.9%) and CTP early-class B (38.2%). Multivariate logistic regression analysis demonstrated that female sex (odds ratio, 3.01; 95% CI, 1.07-8.77; P = .037) and peripheral vascular disease (odds ratio, 4.01; 95% CI, 1.33-12.2; P = .013) were independent predictors of 30-day mortality in patients with advanced LD.

Conclusions: Severity of LD influences perioperative outcomes following cardiac surgery. Our data suggest that patients in CTP class A and selected patients in CTP class B (model for end-stage liver disease score <12.7) can undergo surgery with acceptable risk.
