Results of transcarotid compared with transfemoral transcatheter aortic valve replacement.

The femoral artery is the preferred vascular access to perform transcatheter aortic valve replacement (TAVR). However, the optimal alternative approach has not been elucidated in patients who are not candidates for a transfemoral (TF) access. The objective of this study was to compare the outcomes of TAVR performed by the transcarotid (TC) compared with the TF approach. This was a single-center study that included 526 consecutive patients who underwent TAVR between 2015 and 2019. TC-TAVR was performed in 127 and TF-TAVR in 399 patients. Postprocedural and 30-day clinical events were evaluated according to main access (TC vs TF) using a multivariate logistic regression model. One-year survival and freedom from neurological events were also evaluated. The prevalence of diabetes, chronic obstructive pulmonary disease, coronary artery disease, and peripheral vascular disease was higher in the TC group. In-hospital mortality (3.2% vs 2.0%, adjusted odds ratio, 1.83; 95% confidence interval, 0.47-7.15; P = .39), and 30-day stroke (2.4% vs 3.3%; odds ratio, 0.84; 95% confidence interval, 0.21-3.41; P = .81), were similar between groups as were other outcomes: procedural success (98.4% vs 97.0%; P = .52), 30-day cumulative mortality (4.8% vs 2.8%; P = .26), major vascular complication (2.4% vs 4.5%; P = .25), and major/life-threatening bleeding (4.7% vs 6.0%; P = .41) (TC vs TF, respectively). No differences were found among groups regarding survival or neurological events at 1-year follow-up. The TC approach is a safe alternate-access strategy for TAVR, and is associated with similar outcomes compared with TF-TAVR, despite a higher disease burden in TC patients.
