Axillary Transcatheter Aortic Valve Replacement in Patients With Peripheral Vascular Disease

The axillary artery seems an interesting alternative in nonfemoral transaortic valve replacement (TAVR) patients. This study describes our experience with this technique and its short-term follow-up results. This is a retrospective single center study. All axillary TAVR performed in our department between 2015 and 2017 were included in the study. Mean follow-up was 13.2 ± 9.5 months. All reporting was done according to the VARC-2 criteria. During the period covered, 43 patients had an axillary TAVR. Most patients were men (62.7%), had a mean age of 83.9 ± 5.3 years and presented with EuroSCORE I, II, and STS score of 27.9 ± 13.5%, 5.6 ± 4.9%, and 7.7 ± 4.05%, respectively. Vascular access was successful in all patients with a higher frequency of left approach (69.7%, n = 30). Both Medtronic CoreValve 37.2% (n = 16) and Edwards Sapien3 62.8% (n = 27) valves were used. An apical Certitude delivery system was preferentially used (24/27) in the latter group. There were no reported instances of valve migration or need for a second valve implantation. A single case (2.3%) of arterial vascular complication was reported. Central neurologic morbidity was 2.3%. No patient experienced brachial plexus injury. A pacemaker was implanted in 18.6% of cases (n = 8), with no significant difference between the 2 valves patient groups (S3 14.8% vs CV 25%, P 0.67). The 30-day mortality was 6.9% (n = 3) and 1-year survival was 86% [95% CI 72.6, 93.4]. Axillary TAVR is associated with acceptable morbidity, mortality, and leads to satisfactory short-term clinical outcomes. It has the potential to become the main alternative access route in nonfemoral TAVR patients.
