Abstract

Aims This multicentre study investigated the association of periprocedural changes in the levels of N-terminal pro-B-type natriuretic peptide (NT-proBNP) with clinical outcomes after transcatheter edge-to-edge mitral valve repair (TMVR). Methods and results Patients were retrospectively analysed who underwent TMVR with the MitraClip system (Abbott Vascular, Santa Clara, CA, USA) and had available sequential NT-proBNP testing at baseline and 2 months after TMVR. Periprocedural changes in NT-proBNP following TMVR were assessed as the percent change in NT-proBNP between baseline and the 2 month follow-up, and the significant reduction in NT-proBNP was defined as a decrease of >30% in the follow-up NT-proBNP compared with the pre-procedural NT-proBNP level. Primary outcome was defined as a composite outcome consisting of all-cause mortality and hospitalization due to heart failure from 2 months to 2 years after TMVR. Additionally, we identified the cut-off value of pre-procedural NT-proBNP to predict the composite outcome using a receiver operating characteristic analysis (cut-off: 2485 pg/mL). Of 485 patients undergoing TMVR (age: 76.2 +/- 9.2 years, female: 42.1%, secondary mitral regurgitation: 67.2%), 150 patients (30.9%) had the significant reduction in NT-proBNP (>30%) following the procedure. Patients with the NT-proBNP reduction had a lower incidence of the composite outcome, compared with those without the reduction in NT-proBNP (31.4% vs. 40.2%; log-rank P = 0.03). The significant reduction in NT-proBNP was also associated with a lower risk of the composite outcome [adjusted hazard ratio (HR): 0.67; 95% confidence interval (CI): 0.45-0.97; P = 0.04], independently of pre-procedural NT-proBNP levels and other clinical parameters. The percent change in NT-proBNP was associated with a linear trend of the incidence of the composite outcome (adjusted HR per 10% decrease: 0.96; 95% CI: 0.94-0.98; P < 0.001). A stratified analysis revealed that the prognostic impact of the significant reduction in NT-proBNP was consistent among clinical subgroups, including aetiology of mitral regurgitation (P for interaction = 0.99). Higher pre-procedural NT-proBNP level (>2485 pg/mL) was associated with the increased risk of the composite outcome (adjusted HR: 1.50; 95% CI: 1.03-2.17; P = 0.03); however, patients with a higher pre-procedural NT-proBNP who achieved the significant reduction in NT-proBNP had a similar risk of the composite outcome to those with a lower pre-procedural NT-proBNP. Conclusions Changes in sequential NT-proBNP measurements were associated with clinical outcomes within 2 years after TMVR. The assessment of NT-proBNP dynamics may be valuable to assess the residual risk for patients undergoing TMVR and could assist with post-procedural management after TMVR.
