OBJECTIVE: Native aortic valve @entity460 and transcatheter @entity886 have been reported to predict pacemaker implantation after transcatheter aortic valve insertion. We reviewed our experience to better understand the association. METHODS: We retrospectively reviewed the records of 300 @entity1 with no prior permanent pacemaker implantation who underwent transcatheter aortic valve insertion from November 2008 to February 2015. Valve oversize was calculated using area. The end point of the study was 30-day postoperative pacemaker implantation. RESULTS: @entity1 data included age of 81.1      8.4  years, female sex in 135 @entity1 (45%), @entity955 in 74 @entity1 (24.7%), Society of Thoracic Surgeons predicted risk of mortality of 7.6% (interquartile range [IQR], 5.3-10.6), aortic valve @entity460 score of 2568 (IQR, 1775-3526) Agatston units, and annulus area of 471      82  mm(2). Balloon-expandable valves were inserted in 244 @entity1 (81.3%). Transcatheter @entity886 was 12.8% (IQR, 3.9-23.3). Pacemaker implantation was performed in 59 @entity1 (19.7%). Aortic valve @entity460 score (adjusted P  =  .275) and transcatheter valve oversize (adjusted P  =  .833) were not independent risk factors for pacemaker implantation when controlling for preoperative @entity714 (adjusted odds ratio, 3.49; 95% confidence interval, 1.61-8.55; P  =  .002), implantation of self-expanding valve (adjusted odds ratio, 4.09; 95% confidence interval, 1.53-10.96; P  =  .005), @entity714 (adjusted P  =  .331), previous percutaneous coronary intervention (adjusted P  =  .053), or valve surgery (adjusted P  =  .111), and PR interval (adjusted P  =  .350). CONCLUSIONS: @entity714 and implantation of a self-expanding prosthesis were predictive of pacemaker implantation, but not native aortic valve score or transcatheter valve oversize.

The influence of native aortic valve XXXX and transcatheter valve oversize on the need for pacemaker implantation after transcatheter aortic valve insertion.
