Abstract
AimTo examine procedural and clinical outcomes among patients undergoing percutaneous mitral valve repair (PMVR) within an admission for acute-decompensated heart failure (ADHF). Methods and resultsProspective registry of all consecutive patients with symptomatic mitral regurgitation (MR) grade 3+ or 4+ who underwent PMVR our centre and classified in 2 groups: elective group and urgent PMVR group (within the index admission for ADHF). Echocardiographic, procedural and clinical outcomes were compared between groups. 85 patients (median age 77.0 [67.8–83.4] years, 64.7% male) were treated within the recruitment period. Among them, 17 (20%) underwent urgent MitraClip®. Urgent PMVR were at a higher risk for conventional surgery (p = 0.002) and had worse estimated prognosis according to HF risk scores (p < 0.001). Overall technical success was 100%, without differences between groups. At 30 days, no differences were found in mortality, MR reduction and in NYHA functional improvement between groups. Cumulative estimated survival free from all-cause death was 92.9% (82.4% vs. 95.6%), 89.4% (82.4% vs. 91.1%), 76.3% (82.4 vs. 74.9%) at 6 months, 1-year and 2-years, respectively, with no significant differences between urgent or elective PMVR (p = 0.769). ConclusionMitraClip® implantation can be considered as an urgent therapy during admission for ADHF.
