| Abstract |
The impact of coronary artery disease (CAD) on outcomes after transcatheter aortic valve implantation (TAVI) has not been clarified. Furthermore, less is known about the indication and strategy of revascularization in these high risk patients. This study sought to determine the prevalence and prognostic impact of CAD in patients undergoing TAVI, and to assess the safety and feasibility of percutaneous coronary intervention (PCI) before TAVI. Patients with severe aortic stenosis (AS) undergoing TAVI were included into a prospective single center registry from 2007 to 2012. Clinical outcomes were compared between patients with and without CAD. In some patients with CAD, it was decided to perform elective PCI before TAVI after decision by the Heart team. The primary endpoints were 30-day and 2-year all-cause mortality. A total of 91 consecutive patients with mean age of 79 ± 9 years (52% men) underwent TAVI with a median follow-up duration of 16 months (interquartile range of 27.6 months). CAD was present on 46 patients (51%). At 30-day, the incidences of death were similar between CAD and non-CAD patients (9 and 5%, p = 0.44), but at 2 years were 50% in CAD patients and 24% in non-CAD patients [crude hazard ratio with CAD, 2.2; 95% confidence interval (CI), 1.1-4.6; p = 0.04]. Adjusting for age, gender, left ventricular ejection fraction, and glomerular filtration rate, the hazard of death was 2.6-fold higher in patients with CAD (95% CI, 1.1-6.0; p = 0.03). Elective PCI before TAVI was performed in 13 patients (28% of CAD patients). There were no more adverse events in patients who underwent TAVI + PCI when compared with those who underwent isolated TAVI. In severe symptomatic AS who underwent TAVI, CAD is frequent and adversely impacts long-term outcomes, but not procedure outcomes. In selected patients, PCI before TAVI appears to be feasible and safe. |

Attention Score in Context
This research output has an Altmetric Attention Score of 1. 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 22 December 2015.
All research outputs
#15,352,477
of 22,836,570 outputs
Outputs from Frontiers in Cardiovascular Medicine
#2,549
of 6,719 outputs
Outputs of similar age
#157,114
of 263,998 outputs
Outputs of similar age from Frontiers in Cardiovascular Medicine
#8
of 15 outputs
Altmetric has tracked 22,836,570 research outputs across all sources so far. This one is in the 22nd percentile – i.e., 22% of other outputs scored the same or lower than it.
So far Altmetric has tracked 6,719 research outputs from this source. They receive a mean Attention Score of 4.0. This one has gotten more attention than average, scoring higher than 58% 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 263,998 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 31st percentile – i.e., 31% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 15 others from the same source and published within six weeks on either side of this one. This one is in the 13th percentile – i.e., 13% of its contemporaries scored the same or lower than it.
