Background: Mitral regurgitation (MR) is the most common valvular disease worldwide. MR has been managed surgically, with either a mitral valve replacement or repair. Percutaneous transcatheter mitral valve repair (TMVr) with MitraClip® insertion has gained wide popularity and success over medical and surgical therapy for MR. Some patients with acute MR or decompensated heart failure could benefit from urgent TMVr. This meta-analysis aims to compare clinical outcomes of urgent versus elective TMVr. Methods: We performed a study-level meta-analysis to compare the clinical outcomes of urgent versus elective TMVr using the MitraClip system. The primary endpoint outcome was all-cause mortality. Additional outcomes included procedural success, postoperative acute kidney injury (AKI), stroke, and length of in-hospital stay. Results: Overall, 30-day mortality was significantly higher in the urgent group (odds ratio [OR]: 2.74; 95% confidence interval [CI] [2.17, 3.48]; P < 0.00001; I
2 =0%). However, subgroup analysis of matched cohorts showed no significant difference between both groups (OR: 1.80; 95% CI [0.94, 3.46]; P = 0.08; I2 =0%). One-year mortality was similar between both groups (and: 1.67; 95% CI [0.96, 2.90]; P = 0.07; I2 =0%). Procedural success was similar between both groups (89.4% vs. 89.8%; P = 0.43). Postoperative AKI was significantly higher in the urgent group (OR: 4.12; 95% CI [2.87, 5.91]; P < 0.00001; I2 =0%). Conclusion: Urgent TMVr should be indicated in select populations as it is considered therapeutic with acceptable outcomes therein. [ABSTRACT FROM AUTHOR]- Published
