Permanent pacemaker implantation
The primary endpoint of the study was PPI within 30 days after TAVR. The
indications for PPI following TAVR were: persistent high degree
atrioventricular block (AVB), new onset alternating bundle branch block,
pre-existing right bundle branch block (RBBB) with new post-procedure
conduction disturbance. Among the 179 included in the study, 48 had
previous CAs (11 1st degree AVB, 31 right or left
bundle branch block (RBBB or LBBB), 6 AVB and RBBB or LBBB), and 131 had
no evidence of CAs at hospital admission. Thus, the analysis included 48
patients with pre-TAVR CAs and 131 patients without pre-TAVR CAs. The
two groups were assessed for new onset CAs requiring PPI (Table 1).
The study protocol was approved by our local institutional review board
(#000127/2017). The present study complies with the Declaration of
Helsinki.
