Abstract

BACKGROUND: Nationwide studies documenting temporal trends in permanent pacemaker implantation (PPMI) following transcatheter aortic valve replacement (TAVR) are limited. METHODS AND RESULTS: We selected patients who underwent TAVR between 2012 and 2017 in the National Readmission Database. The primary end point was the 6-year trend in post-TAVR PPMI at index hospitalization and at 30, 90, and 180 days after discharge. The secondary end point was the association between PPMI and in-hospital mortality, stroke, cost, length of stay, and disposition. Among the 89 202 patients who underwent TAVR, 77 405 (86.8%) with no prior pacemaker or defibrillator were included. Patients who required PPMI had a higher prevalence of atrial fibrillation (43.6% versus 38.7%, P<0.001) and conduction abnormalities (28.4% versus 15.3%, P<0.001). The incidence of PPMI during index admission increased from 8.7% in 2012 to 13.2% in 2015, and then decreased to 9.6% in 2017. The incidence of inpatient PPMI within 30 days after discharge increased from 0.5% in 2012 to 1.25% in 2017 (Ptrend <0.001). Inpatient PPMI beyond 30 days remained rare (<0.5%) during the study period. After risk adjustment, PPMI was not associated with in-hospital mortality or stroke but was associated with increased nonhome discharge, longer hospitalization, and higher cost. The incremental expenditure associated with post-TAVR PPMI during index admission increased from $9.6 million to $72.2 million between 2012 and 2017. CONCLUSIONS: After an upward trend, rates of PPMI after TAVR in the United States stabilized at ~10% in 2016 to 2017, but there was a notable increase in PPMI within 30 days after the index admission. PPMI was not associated with increased in-hospital morbidity or mortality but led to longer hospitalization, higher cost, and more nonhome discharges.
