In STEMI patients undergoing primary PCI, AKI assessed by AKIN criteria is a frequent complication, associated with an increased risk of both short- and long-term mortality.
Objective
Determine the rates, reasons, predictors, and costs of 30‐day readmissions following transcatheter mitral valve repair (TMVR) versus surgical mitral valve repair (SMVR) in the United States.
Background
Data on 30‐day readmissions after TMVR are limited.
Methods
High‐risk patients with mitral regurgitation (MR) undergoing TMVR or SMVR were identified from the 2014–2015 Nationwide Readmissions Databases. Multivariable stepwise regression models were used to identify independent predictors of 30‐day readmission. Risk of 30‐day readmission was compared between the two groups using univariate and propensity score adjusted regression models.
Results
Among 8,912 patients undergoing mitral valve repair during 2014–2015 (national estimate 17,809), we identified 7,510 (84.7%) that underwent SMVR and 1,402 (15.3%) that underwent TMVR. Thirty‐day readmission rates after SMVR and TMVR were 10.7% and 11.7%, respectively (unadjusted OR 1.11, 95% CI 0.89–1.39, p = .35). After propensity score adjustment, TMVR was associated with a lower risk of 30‐day readmissions compared with SMVR (adjusted OR 0.70, 95% CI 0.51–0.95, p = .02). Heart failure and arrhythmias were the leading cardiac reasons for readmission. Anemia and fluid and electrolyte disorder were independent predictors of 30‐day readmission after TMVR. Demographics, comorbidities, and length of stay were independent predictors of 30‐day readmission after SMVR.
Conclusions
One in 10 patients are readmitted within 30 days following TMVR or SMVR. Approximately half of the readmissions are for cardiac reasons. The predictors of 30‐day readmission are different among patients undergoing TMVR and SMVR, but can be easily screened for to identify patients at highest risk for readmission.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
