ABSTRACT
AIMS:
Prognostic impact of post-procedural changes in right ventricular (RV) function after tricuspid transcatheter edge-to-edge repair (T-TEER) is still unclear. We investigated association of RV function and its post-procedural changes with clinical outcomes in patients undergoing T-TEER. METHODS ANDRESULTS:
We retrospectively analysed 204 patients who underwent T-TEER and echocardiographic follow-up at 3 months after T-TEER. RV function was assessed by RV fractional area change (RVFAC), and RV dysfunction was defined as RVFAC <35%. Patients with an increase in RVFAC from baseline to the follow-up were considered as RV responders. Patients were divided into four groups according to baseline RVFAC and the RV responder. The primary outcome was a composite of mortality and hospitalization due to heart failure within 1 year. Forty-five of 204 patients (22.1%) had RVFAC <35% at baseline, and 71 (34.8%) were RV responders. The association between the RV responder and the composite outcome had a significant interaction with RVFAC at baseline. Among patients with baseline RVFAC <35%, RV responders had a lower risk of the composite outcome than RV non-responders, while this association was not significant in those with baseline RVFAC ≥35%. Among patients with baseline RVFAC <35%, a smaller RV diameter and a greater reduction of tricuspid regurgitation were predictors for the RV responder.CONCLUSION:
Post-procedural increase in RVFAC after T-TEER is associated with improved outcomes in patients with RV dysfunction. The factors related to the increase in RVFAC may support patient selection for T-TEER in patients with RV dysfunction.Palavras-chave
