AIMS Transcatheter aortic valve implantation (TAVI) is performed through a transarterial approach with encouraging results in "one-type valve" registries. We report 30-day data from a mixed population of patients treated with either Medtronic CoreValve (MCV) or Edwards SAPIEN (ES) valves. METHODS AND RESULTS Forty-five patients had TAVI via the transarterial approach (21 MCV and 24 ES). Mean age was 81.8+/-4.2 years, Logistic EuroSCORE was 25.2+/-8.4%. Procedural success rate was 97.8%. In-hospital death rate was 4.4%. Vascular complication rate was 8.9%. Of MCV patients, 28.6% had a permanent pacemaker vs. 4.2% of ES patients; p=0.02. No additional deaths were observed between discharge and 30 days. NYHA functional class was improved at 30-days: 2.07+/-0.4 vs. 3.09+/-0.05, p
