Impact of pre-existing conduction abnormalities on permanent pacemaker implantation after transcatheter aortic valve replacement: A meta-analysis

Figure 6 Forest plot depicting the association between pre-existing right bundle branch block and permanent pacemaker implantation after transcatheter aortic valve replacement across four studies (n = 2160) using random-effects restricted maximum likelihood analysis. Pooled odds ratio (OR) = 4.52 (95%CI: 2.64-7.74); I² = 50.3%, P < 0.001. Individual study ORs ranged from 2.23 (Wasim et al[30]) to 8.61 (Bagur et al[23]). Valve platforms are indicated per study. OR: Odds ratio; BEV: Balloon-expandable valve; SEV: Self-expanding valve.
