Background: Surgery for isolated tricuspid regurgitation is associated with high morbidity and mortality and is rarely performed. Transcatheter edge-to-edge repair (TEER) of the tricuspid valve (TV) is an attractive alternative to TV surgery. We aimed to examine the trends in utilization and outcomes of TV TEER.

Methods: The Nationwide Readmissions Database was queried using the International Classification of Diseases, Tenth Revision, procedure code for TEER of TV for the years 2016-2018. The main outcomes were trends in utilization and in-hospital all-cause mortality.

Results: We identified 420 hospitalizations for TEER of the TV. There was an uptrend in its utilization over time: from 13 cases in the first quarter of 2016 to 98 cases in the last quarter of 2018 (P trend < 0.001). Concomitant TEER of the MV was performed in 38.1% of admissions. The overall in-hospital mortality was 1.7%, and cardiogenic shock occurred in 7.3%, complete atrioventricular block in 2.5%, and tamponade in 1.2% of admissions. Surgical TV replacement was needed in 1.5% of admissions, none of which patients died during the index hospitalization. Unplanned rehospitalizations were common at 30 days (17.4%), 41% of them due to heart failure. There was no difference in in-hospital mortality between isolated TV TEER and combined mitral valve and TV TEER (2.3% vs 0.6%; P = 0.260).

Conclusion: In this nationwide study, there was an increase in the utilization of TV TEER. TV TEER was associated with low rates of in-hospital mortality and morbidity; however, the rate of urgent readmission remains high, mainly owing to heart failure. The ongoing TRILUMINATE Pivotal Trial and future trials will give a better understanding of the role of TV clipping for the management of severe TR.
