Abstract

The study sought to determine the risk factors for post-transcatheter aortic valve replacement (TAVR) dialysis and to determine the impact of pre-TAVR or post-TAVR dialysis on mortality. TAVR is now established as an alternative treatment to surgical aortic valve replacement. Data examining the impact of dialysis on outcomes after TAVR are lacking. The UK TAVI (Transcatheter Aortic Valve Implantation) Registry was established to report outcomes on all TAVR procedures performed within the United Kingdom (2007 to 2014). Data were collected prospectively on 6,464 patients with a median follow-up of 625 days. The proportion of patients on dialysis before TAVR has remained constant at 1.8%. After TAVR, the proportion of patients newly needing dialysis after TAVR has fallen from 6.1% (2007 to 2008) to 2.3% (2013 to 2014). The risk of new dialysis requirement after TAVR was independently associated with lower baseline renal function, year of procedure, impaired left ventricular function, diabetes, use of an Edwards valve, a nontransfemoral approach, need for open surgery, and moderate-to-severe aortic regurgitation after the procedure. Requirement for new dialysis after TAVR was associated with higher mortality at 30 days (hazard ratio: 6.44; 95% confidence interval: 4.87 to 8.53) and at 4 years (hazard ratio: 3.54; 95% confidence interval: 2.99 to 4.19; p < 0.001 for all) compared with patients without dialysis requirement. The proportion of patients needing dialysis after TAVR has decreased over time. Post-TAVR dialysis is associated with increased mortality. Factors identified with dialysis requirement after TAVR require further investigation.

Attention Score in Context

Attention Score in Context

This research output has an Altmetric Attention Score of 33. 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 06 June 2019.
All research outputs
#1,203,821
of 25,382,440 outputs
Outputs from JACC: Cardiovascular Interventions
#493
of 4,032 outputs
Outputs of similar age
#24,066
of 327,230 outputs
Outputs of similar age from JACC: Cardiovascular Interventions
#11
of 91 outputs
Altmetric has tracked 25,382,440 research outputs across all sources so far. Compared to these this one has done particularly well and is in the 95th percentile: it's in the top 5% of all research outputs ever tracked by Altmetric.
So far Altmetric has tracked 4,032 research outputs from this source. They typically receive a lot more attention than average, with a mean Attention Score of 15.2. This one has done well, scoring higher than 87% 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 327,230 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 92% of its contemporaries.
We're also able to compare this research output to 91 others from the same source and published within six weeks on either side of this one. This one has done well, scoring higher than 86% of its contemporaries.
