ABSTRACT
BACKGROUND:
The aim of this study is to evaluate the predictors of permanent pacemaker (PPM) implantation after TAVI.METHODS:
Between January 2008 and February 2012, 418 patients with severe aortic stenosis underwent TAVI and were enrolled in a Brazilian multicenter registry. After excluding patients who died during the procedure and those with a previous PPM, 353 patients were included in the analysis.RESULTS:
At 30 days, the overall incidence of PPM implantation was 25.2%. Patients requiring PPM were more likely to be older (82.73 vs. 81.10 years, p=0.07), have pre-dilation (68.42% vs. 60.07%, p=0.15), receive CoreValve (93.68% vs. 82.55%, p=0.008), and have baseline right bundle branch block (RBBB, 25.26% vs. 6.58%, p<0.001). On multivariable analysis, CoreValve vs. Sapien XT (OR, 4.24; 95% CI, 1.56-11.49; p=0.005), baseline RBBB (OR, 4.41; 95% CI, 2.20-8.82; p<0.001), and balloon pre-dilatation (OR, 1.75; 95% CI, 1.02-3.02; p=0.04) were independent predictors of PPM implantation.CONCLUSION:
PPM implantation occurred in approximately one-fourth of cases. Pre-existing RBBB, balloon pre-dilatation, and CoreValve use were independent predictors of PPM after TAVI. The type of prosthesis used and pre-balloon dilatation should be considered in TAVI candidates with baseline RBBB.Key words
