P
eripheral artery disease (PAD) affects >200 million people
worldwide, including >50 million people in Europe and
North America, with symptoms ranging from none to critical
limb ischemia.
1
Its prevalence is known to increase in those
over the age of 50 years, especially in those with other vascu-
lar risk factors, including diabetes mellitus, hyperlipidemia,
smoking, and chronic renal insuffciency.
2
These risk factors
overlap with those of aortic stenosis.
3
Given the shared risk factors, PAD is a frequent comor-
bidity in patients referred for transcatheter aortic valve
replacement (TAVR).
4
In clinical trials, the prevalence of
PAD in patients undergoing TAVR ranged from 27.8% in
the PARTNER B (prohibitive risk) trial (Placement of Aortic
Transcatheter Valves, Cohort B) to 41.3% in the CoreValve
US study.
5,6
However, the population studied in clinical trials
may differ from the population undergoing commercial TAVR
in important ways; commercial TAVR patients are more often
men and have lower operative risk than patients enrolled in
pivotal trials, for example.
7,8
Moreover, PAD has been associ-
ated with increased cardiovascular mortality and stroke risk
in the general population and in patients undergoing coro-
nary artery bypass grafting
9–11
and may therefore represent an
Background—Peripheral artery disease (PAD) is associated with increased cardiovascular mortality, and PAD risk factors
overlap with those for aortic stenosis. The prevalence and outcomes associated with PAD in a population undergoing
transcatheter aortic valve replacement (TAVR) are unknown.
Methods and Results—Using the Society of Thoracic Surgeons/Transcatheter Valve Therapy Registry linked to Medicare
claims data, we identifed patients ≥65 years old undergoing TAVR from 2011 to 2015. We calculated hazard ratios for
1-year adverse outcomes, including mortality, readmission, and bleeding, for patients with PAD compared with those
without, adjusting for baseline characteristics and postprocedure medications. Analyses were performed separately by
access site (transfemoral and nontransfemoral). Of 19 660 patients undergoing transfemoral TAVR, 4810 (24.5%) had
PAD; 3730 (47.9%) of 7780 patients undergoing nontransfemoral TAVR had PAD. In both groups, patients with PAD were
signifcantly more likely to have coronary and carotid artery diseases. At 1-year follow-up, patients with PAD undergoing
TAVR via transfemoral access had a higher incidence of death (16.8% versus 14.4%; adjusted hazard ratio, 1.14; P=0.01),
readmission (45.5% versus 42.1%; hazard ratio, 1.11; P<0.001), and bleeding (23.1% versus 19.7%; hazard ratio, 1.18;
P<0.001) compared with patients without PAD. Patients with PAD undergoing TAVR via nontransfemoral access did not
have signifcantly higher rates of 1-year mortality or readmission compared with patients without PAD.
Conclusions—PAD is common among patients undergoing commercial TAVR via transfemoral and nontransfemoral access.
Among patients undergoing transfemoral TAVR, PAD is associated with a higher incidence of 1-year adverse outcomes
compared with absence of PAD.
