Comparative analysis of postoperative outcomes following surgical and transcatheter edge-to-edge mitral valve repair for secondary mitral regurgitation: a meta-analysis & systematic review.

Both outcomes were higher in the SMVr group but did not reach statistical significance (acute renal failure: RR = 1.23; 95% CI = 0.84–1.80; p = 0.28; I 2 = 9%; Figure 13 ; postoperative myocardial infarction: RR = 1.07; 95% CI = 0.71–1.62; p = 0.73; I 2 = 0%; Figure 14 ). 3.5 Mid term outcome 3.5.1 Mid term mortality Despite in-hospital mortality outcome analysis favoring the TEER strategy, during a total follow-up of 211,976 person-months, 253 deaths occurred in the SMVr group and 676 deaths in the TEER group.
