Background: The data on readmissions following tricuspid valve repair/replacement (TVR) are scarce. We examined rates, predictors, causes, and outcomes of readmissions after TVR, using the National Readmission Database. Methods: The International Classification of Diseases—9th version was used to identify the patients who underwent isolated TVR or concomitant aortic, mitral, and coronary bypass surgeries. Rates, causes, and outcomes were assessed using the analysis of variance and the χ2 test, and predictors of readmissions were evaluated using multivariate analysis. Results: A total of 8254 patients who underwent TVR during 2013 to 2014 were included, of whom 1994 (24.16%) were isolated, and 6260 (75.84%) were performed concomitantly with other heart valve or coronary bypass surgery. A total of 1720 (20.84%) patients were readmitted within 30 days. The readmission rates were 448 (22.46%) after isolated TVR and similar after concomitant TVR (TVR + aortic valve replacement, TVR + mitral valve repair, TVR + coronary artery bypass graft, and TVR + multiple) (P =.194); whereas 1305 (20.11%) and 414 (23.45%) were after tricuspid valve repair and replacement (P =.080), respectively. The independent predictors of readmission were acute kidney injury during index visit and Charlson comorbidity index of more than 2. Mean time to readmission and median length of stay during readmission were 13.02 (±7.93) and 5 (interquartile range: 3-9) days, respectively. Total mortality during rehospitalization was 105 (6.1%), a very high (26.86%) number of patients were discharged to skilled facilities after readmission. Conclusions: One out of five patients were readmitted within 30 days after the TVR, associated with 6.1% mortality during rehospitalization, and very high need for skilled facility placement.
