Transcatheter aortic valve implantation (TAVI) is recommended in patients with severe aortic stenosis that is either inoperable or at high-risk for surgical valve replacement.


To evaluate trends in the feasibility and safety of transfemoral TAVI over the past 4 years.


Between 2010 and 2013, all consecutive patients undergoing TAVI in our institution were included in a prospective registry. Population characteristics and 30-day and 1-year outcomes were analysed. Outcomes were classified according to the Valve Academic Research Consortium-2.


Overall, 429 patients underwent TAVI; transfemoral access was used in 368 (85.7%). The proportion of patients treated via a transfemoral approach increased (70.1% to 89.9%; P<0.0001) and the use of prior balloon aortic valvuloplasty decreased (44.7% to 11.2%; P<0.0001). The mean logistic EuroSCORE decreased significantly from 19.4±10.9% to 15.8±8.7% (P=0.01). The 30-day mortality rate did not change significantly (6.4% vs. 5.6%; P=0.99). Similarly, rates of major vascular complications (12.8% vs. 15.4%; P=0.87) and stroke (2.1% vs. 1.4%; P=0.75) remained unchanged. Mean length of stay after TAVI decreased significantly from 8.9±11.3 days to 4.8±4.7 days (P=0.002) and 72 (50.3%) patients were discharged early in 2013. One-year survival increased significantly from 81.0% to 94.4% (P=0.03).


Over the past 4 years, TAVI has been increasingly performed using a transfemoral approach. Treated patients are at lower-risk with less co-morbidity. Thirty-day mortality and complications remained unchanged, but length of stay after TAVI and 1-year mortality decreased dramatically.
