Peripheral vascular disease (PVD) is common in patients referred for transcatheter aortic valve implantation (TAVI). We sought to investigate the impact of PVD on patients who underwent TAVI. Using data from the National Inpatient Sample database 2011 and 2014, we identified patients who had undergone TAVI. We studied the clinical characteristics and procedural outcomes in patients with PVD who underwent TAVI compared with those patients without PVD using propensity score matching score matching. Results: A total of 42,215 patients underwent TAVI; of which 1,388 patients were matched using propensity score matched scores to 694 in each (PVD vs no PVD) patients. The population had a mean age of 81 years old and 55.8% were of female gender. African-Americans constituted 4.3%. PVD patients who underwent TAVI were found to have higher rates of vascular complications (11.8% vs 5.9 % p <0.001) compared with non-PVD patients and tended to have higher mortality (5.5% vs 3.6%, p = 0.121) and post-TAVI bleeding (13.5% vs 12% p = 0.143). In conclusion, PVD patients have higher in-hospital mortality and higher incidence of in-hospital overall complications compared with patients who have no PVD.
