Abstract
OBJECTIVES: The aim of this study was to determine the prevalence of peripheral artery disease (PAD) and its association with in-hospital outcomes after endovascular transcatheter aortic valve replacement (EV-TAVR).
BACKGROUND: TAVR is an established treatment for patients at prohibitive, high, or intermediate surgical risk. PAD is a significant comorbidity in the determination of surgical risk. However, data on association of PAD with outcomes after EV-TAVR are limited.
METHODS: Patients in the National Inpatient Sample who underwent EV-TAVR between January 1, 2012 and September 30, 2015 were evaluated. The primary outcome was in-hospital mortality.
RESULTS: A total of 51,685 patients underwent EV-TAVR during the study period. Of these, 12,740 (24.6%) had a coexisting diagnosis of PAD. The adjusted odds for in-hospital mortality [OR 1.08 (95% CI 0.83-1.41)], permanent pacemaker implantation [OR 0.98 (0.85-1.14)], conversion to open aortic valve replacement [OR 1.05 (0.49-2.26)], or acute myocardial infarction [OR 1.31(0.99-1.71)] were not different in patients with versus without PAD. However, patients with PAD had greater adjusted odds of vascular complications [OR 1.80 (1.50-2.16)], major bleeding [OR 1.20 (1.09-1.34)], acute kidney injury (AKI) [OR 1.19 (1.05-1.36)], cardiac complications [aOR 1.21 (1.01-1.44)], and stroke [OR 1.39(1.10-1.75)] compared with patients without PAD. Length of stay (LOS) was significantly longer for patients with PAD [7.23 (0.14) days vs. 7.11 (0.1) days, p < 0.001].
CONCLUSION: Of patients undergoing EV-TAVR, ~25% have coexisting PAD. PAD was not associated with increased risk of in-hospital mortality but was associated with higher risk of vascular complications, major bleeding, AKI, stroke, cardiac complications, and longer LOS.
