AIMS: To evaluate the impact of tricuspid regurgitation (TR) on echocardiographic and functional outcome after mitral valve transcatheter edge-to-edge-repair (M-TEER).
METHODS AND RESULTS: A total of 740 patients underwent M-TEER at our center from 2010 to 2021. Patients were analyzed according to severity of concomitant TR at the time of M-TEER procedure: low-grade TR (grade ≤I [trace-mild], 279 patients [37.7%]), moderate TR (grade II, 170 patients [23.0%]) and high-grade TR (grade III-V [severe-torrential], 291 patients [39.3%]). Patients with moderate to high-grade TR had higher morbidity. Procedural success of M-TEER was achieved similarly in all groups (98.2% vs. 97.6% vs. 95.9%, p = 0.22). TR severity decreased rapidly and consistently after M-TEER to only 48.0% of high-grade TR patients after 3 months (p < 0.001) and to 46.8% after 12 months (p = 0.99). High-grade TR patients had significantly higher mortality (21.5% vs. 18.2% vs. 11.1%, p = 0.003) up to 12 months after M-TEER. However, high-grade TR did not independently predict mortality (HR 1.302, 95% CI 0.937-1.810; p = 0.116). Echocardiographic and functional outcome was similar in both secondary and primary MR patients.
CONCLUSIONS: High-grade concomitant TR did not independently predict adverse outcome following M-TEER. A wait-and-observe approach for these patients is reasonable.
