Transcarotid (TC) access for transcatheter aortic valve replacement (TAVR) is emerging as an alternative to more traditional nonfemoral access options like transapical (TA) or transaortic (TAo); however, comparative data are limited. The purpose of the study was to analyze outcomes following TAVR using TC as compared to transthoracic (TA/TAo) access.
The Society of Thoracic Surgeons / American College of Cardiology Transcatheter Valve Therapy Registry™ was queried for patients who underwent TC, TA, or TAo TAVR with the SAPIEN 3 transcatheter heart valve between June 2015 and July 2019. Thirty-day unadjusted outcomes were evaluated and propensity score matching and logistic regression were used to compare TC access with transthoracic access.
In the propensity matched analysis, 667 TC TAVR procedures were compared to 1334 transthoracic procedures. TC TAVR was associated with lower mortality (4.2% vs 7.7%, p=0.004), less new-onset atrial fibrillation (2.2% vs 12.1%, pConclusions TAVR using TC access is associated with lower 30-day mortality, less atrial fibrillation, shorter ICU and overall LOS, fewer readmissions, greater improvement in KCCQ scores and no significant difference in stroke or major vascular complications compared to transthoracic access.
