ABSTRACT
@#BACKGROUND:
This study aims to investigate whether small balloon aortic valvuloplasty (BAV) reduces the need for permanent pacemaker implantation (PPMI) after transcatheter aortic valve implantation (TAVI).METHODS:
This was a retrospective analysis using data from our local TAVI database. Small BAV was defined as a small balloon size (=18 mm) pre-dilatation. Normal BAV was defined as a balloon size >18 mm. The primary endpoint was the incidence of new PPMI.RESULTS:
Of 99 consecutive TAVI patients, five patients were excluded due to pre-existing permanent pacemaker. Patients in the small BAV group (n=57) had a significantly lower PPMI rate compared with the normal BAV group (n=37) (3.5% vs. 18.9%, P=0.026). Moderate or severe aortic valve regurgitation post-procedure was similar between the small BAV and normal BAV groups (5.3% vs. 8.1%, P=0.480); likewise, the mean aortic gradient post-procedure did not differ significantly (11.5±5.2 mmHg vs. 12.2±7.3 mmHg, 1 mmHg=0.133 kPa, P=0.580) between the groups. Device success rates were also similar (94.7% vs. 91.8%, P=0.680). In multivariable analysis, small BAV (P=0.027), the ratio of prosthesis diameter to annulus diameter (P=0.048), and mean aortic gradient by echo in the basement (P=0.021) were independent predictors of PPMI.CONCLUSIONS:
The small BAV strategy is associated with a low rate of permanent pacemaker implantation after transcatheter self-expanding valve implantation in this single-center observational study.
