BACKGROUND: The femoral artery is generally used as primary access for transcatheter aortic valve implantation. However, peripheral artery disease often precludes femoral access. The purpose of this study was to describe clinical outcome of transcatheter aortic valve implantation using the left axillary artery (LAA) as primary access site. METHODS: From December 2008 until June 2016, data on all consecutive patients treated with a Medtronic device through the LAA at our hospital were registered, and outcome was prospectively collected according to the updated Valve Academic Research Consortium-2 criteria. Mortality check was performed nationally. RESULTS: In total, 362 patients were included (median age 80 years [range, 76 to 84]; logistic European System for Cardiac Operative Risk Evaluation 17% +/- 12%). Successful axillary access was achieved in 99%. Medtronic CoreValve (86%) and Evolut R (14% [Medtronic, Minneapolis, MN]) were implanted. Major vascular complications occurred in 5% of patients, 1% was LAA related. Life-threatening bleeding and major bleeding were observed in 2% and 10%, respectively. Additional complications were new left bundle branch blood (30%), new permanent pacemaker (11%), and stroke (1%). There were 6 procedural deaths (2%) and 19 deaths (5%) within 30 days. One-year mortality rate was 19%. CONCLUSIONS: This is the first study reporting outcome after transcatheter aortic valve implantation using the LAA as default access. We conclude that it is highly feasible and safe with low rates of major vascular complications, bleeding, and stroke.
