Why the study?
Does TAVI with the CoreValve system improve acute and short-term echocardiographic hemodynamic parameters in high-risk patients with aortic stenosis?
Population
60 high-risk patients with aortic stenosis (26 males, 34 females; mean age 84.7 ± 5.8)
Design
Cohort
Follow-up
3 months
Key result
TAVI with the CoreValve system significantly improved aortic valve area (from 0.64 to 1.67 cm2, P<0.001) and mean gradient (from 51.9 to 8.8 mmHg, P<0.001) immediately post-procedure.

Does TAVI with the CoreValve system improve acute and short-term echocardiographic hemodynamic parameters in high-risk patients with aortic stenosis?
Absolute Event Rate: 1.67% vs 0.64%
p-value: p=<0.001
TAVI with the CoreValve system provides immediate and short-term (3-month) improvements in cardiac hemodynamics, including increased aortic valve area, reduced gradients, and favorable left ventricular reverse remodeling.
Silva et al. (2014) conducted an observational in aortic stenosis (n=60). Transcatheter aortic valve implantation (TAVI) with CoreValve system vs. Baseline (pre-procedure) was evaluated on aortic valve area (AVA) (p=<0.001). TAVI with the CoreValve system significantly improved aortic valve area (from 0.64 to 1.67 cm2, P<0.001) and mean gradient (from 51.9 to 8.8 mmHg, P<0.001) immediately post-procedure.
