Context: Triple valve surgery (TVS) is a relatively higher in-hospital mortality rate than any isolated valve surgery. In advanced-stage valvular heart disease, maladaptation may occur, creating RV-PA uncoupling. Aims To evaluate whether RV-PA coupling is associated with the in-hospital outcome of patients after TVS. Settings and Design: From the medical records, clinical and echocardiography data were collected and compared between the survived and patients with in-hospital mortality groups. Methods and Material: Patients with the rheumatic multivalvular disease who underwent triple valve surgery were included in the study. Statistical and analysis used Uni and bivariate analysis assessed any association between the RV-PA coupling using TAPSE/PASP and other clinical variables with the in-hospital mortality post TVS. Result: From 269 patients, the in-hospital mortality rate was 10 %. The median value of TAPSE/PASP ratio in all group is 0.41 (0.02-5.79). Impaired RV-PA coupling which value < 0.36 occurs in 38.3 % population. By multivariate analysis, independent predictors of in-hospital mortality were TAPSE/PASP < 0.36 (OR 3.46, 95 % CI 1.21 – 9.89; P 0.02), age (OR 1.04, 95 % CI 1.003-1.094; P 0.035), CPB duration, (OR 1.01, 95 % CI 1.003-1.017; P 0.005). Conclusion: RV-PA uncoupling assessed by TAPSE / PASP ratio < 0.36 is associated with the in-hospital mortality in patients post triple valve surgery. Other factors associated with the outcome were older age and longer CPB machine duration.
