| Abstract |
-Surgical risk scores do not include frailty assessments (e.g., gait speed), which are of particular importance for severe aortic stenosis patients considering transcatheter aortic valve replacement (TAVR). -We assessed the association of 5-meter gait speed with outcomes in a cohort of 8039 patients who underwent TAVR (11/2011-06/2014) and were registered in the Society of Thoracic Surgeons/American College of Cardiology Transcatheter Valve Therapy Registry™ (STS/ACC TVT Registry). We evaluated the association between continuous and categorical gait speed and 30-day all-cause mortality before and after adjustment for STS-predicted risk of mortality score and key variables. Secondary outcomes included in-hospital mortality, bleeding, acute kidney injury, and stroke. The median gait speed was 0.63 m/s (0.47-0.79), with the slowest walkers (<0.5 m/s) constituting 28%, slow walkers (0.5 to 0.83 m/s) 48%, and normal walkers (>0.83 m/s) 24% of the population. Thirty-day all-cause mortality rates were 8.4%, 6.6%, and 5.4% for slowest, slow, and normal walkers, respectively (p<0.001). Each 0.2 m/s decrease in gait speed corresponded to an 11% increase in 30-day mortality (adjusted odds ratio 1.11, 95% confidence interval 1.01-1.22). The slowest walkers had 35% higher 30-day mortality than normal walkers (adjusted odds ratio 1.35, 95% confidence interval 1.01-1.80), significantly longer hospital stays, and a lower probability of being discharged to home. -Gait speed is independently associated with 30-day mortality following TAVR. Identification of frail patients with the slowest gait speeds facilitates pre-procedural evaluation and anticipation of a higher level of post-procedural care.

Attention Score in Context
This research output has an Altmetric Attention Score of 20. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 23 August 2016.
All research outputs
#1,900,832
of 25,782,917 outputs
Outputs from Circulation
#4,213
of 21,264 outputs
Outputs of similar age
#29,740
of 313,194 outputs
Outputs of similar age from Circulation
#78
of 180 outputs
Altmetric has tracked 25,782,917 research outputs across all sources so far. Compared to these this one has done particularly well and is in the 92nd percentile: it's in the top 10% of all research outputs ever tracked by Altmetric.
So far Altmetric has tracked 21,264 research outputs from this source. They typically receive a lot more attention than average, with a mean Attention Score of 31.5. This one has done well, scoring higher than 80% of its peers.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 313,194 tracked outputs that were published within six weeks on either side of this one in any source. This one has done particularly well, scoring higher than 90% of its contemporaries.
We're also able to compare this research output to 180 others from the same source and published within six weeks on either side of this one. This one has gotten more attention than average, scoring higher than 56% of its contemporaries.
