Abstract:
Reoperative tricuspid valve (TV) surgery is considered high risk even in the absence of additional concomitant cardiac procedures. The purpose of this study was to evaluate preoperative clinical parameters as predictors for survival after isolated reoperative TV surgery. METHODS From January 2005 to January 2019, 85 patients (mean age: 66.7 ± 10.3 years, 34 male) with severe isolated TV regurgitation and prior cardiac surgery were referred to our centre for elective or urgent TV repair/replacement; patients with endocarditis were excluded. We retrospectively analysed preoperative hepatorenal function [reflected by widely used clinical and laboratory parameters and the Model of End-stage-Liver Disease excluding International Normalized Ratio (MELD-XI) score] as a predictor for postoperative survival. RESULTS At hospital admission, the patients’ average preoperative New York Heart Association class was 2.9 ± 0.6, left ventricular ejection fraction 52.5 ± 10.6%, mean pulmonary artery pressure 24.7 ± 8.0 mmHg, creatinine 115.4 ± 66.6 μmol/l, bilirubin 20.0 ± 19.6 μmol/l and the mean MELD-XI score was 13.3 ± 4.0 μmol/l. The mean follow-up was 5.4 ± 4.2 years. Thirty-day mortality was 5%, 5-year survival was 60.6 ± 5.4% and 10-year survival was 42.9 ± 6.5%. The multivariable Cox regression analysis evaluated the MELD-XI score [hazard ratio (HR 1.144, confidence interval 95% 1.0–1.3, P = 0.005] and diabetes mellitus (HR 2.27, confidence interval 95% 1.0–5.0, P = 0.04) as significant predictors for excess mortality while age and mean pulmonary artery pressure did not reliably predict clinical outcome. CONCLUSIONS Hepatorenal dysfunction was one main factor accounting for limited postoperative survival in our patient cohort. The MELD-XI score is easy to calculate and seems to reliably predict the perioperative risk in patients with prior cardiac surgery and indication for TV surgery.
