Smith CR, Leon MB, Mack MJ, Miller DC, Moses JW, Svensson LG, PARTNER Trial Investigators et al (2011) Transcatheter versus surgical aortic-valve replacement in high-risk patients. While SE THV were associated with lower rates of vascular complications, BE THV were more often used in cases with challenging anatomical circumstances. However, SE THV were more often used and were associated with a higher rate of device success. Conclusionsīoth, SE and BE THV can be safely used in TAx-TAVI.
In logistic regression analysis, BE THV were a risk factor for vascular complications and axillary stent implantation. TAx-TAVI was more often conducted by right sided axillary artery in the BE group (33/368, 9.0% vs 17/64, 26.6% p < 0.001). Imaging revealed lower axillary artery diameters in the SE group (max/min diameter in mm: 8.4/6.6 vs 9.4/6.8 mm p < 0.001/ p = 0.04) but a higher proportion of axillary tortuosity in BE group (62/368, 23.6% vs 26/64, 42.6% p = 0.004) with steeper aorta-left ventricle (LV) inflow (55° vs 51° p = 0.002) and left ventricular outflow tract (LVOT)-LV inflow angles (40.0° vs 24.5° 0.002). Resultsįrom 432 patients, 368 patients (85.3%, SE group) received self-expanding (SE) THV and 64 patients (14.8%, BE group) received balloon-expandable (BE) THV. Acute procedural, early and 1-month clinical outcomes were adjudicated in accordance with standardized VARC-3 definitions. Methodsįor the TAXI registry anonymized data of patients treated with TAx-TAVI were collected from 18 centers. This study used the Trans-AXillary Intervention (TAXI) registry to compare procedural success according to different types of transcatheter heart valves (THV). Transaxillary (TAx) transcatheter aortic valve implantation (TAVI) is a preferred alternative access in patients ineligible for transfemoral TAVI.
