Abstract

Background: The choice of an alternative access for transcatheter aortic valve replacement (TAVR) remains controversial when transfemoral (TF) access is not feasible. Methods: We conducted a network meta-analysis to compare the outcomes of TAVR via various peripheral vascular accesses. MEDLINE and EMBASE were searched through July 2022 to identify studies that investigated outcomes in patients who underwent TAVR via TF, trans-subclavian (Tsc), transcarotid (TC), or transcaval (Tcav) access. A network meta-analysis was conducted via random-effects model. Outcomes of interest were major or life-threatening bleeding, stroke, major vascular complication, and 30-day mortality. Results: No randomized trial was identified. Our analysis included 33 observational studies that enrolled a total of 43,455 patients who underwent TAVR via TF (n = 36,202), Tsc (n = 3869), TC (n = 3066), or Tcav (n = 318) access. The risk of major or life-threatening bleeding was higher via Tsc compared with TF [odds ratio (OR); 95 % confidence interval (CI) =1.51 (1.03–2.23), p = 0.034]. The risk of stroke was higher via Tsc compared with TF and Tcav [OR (95 % CI) =2.00 (1.14–3.52), p = 0.018, OR (95 % CI) =2.43 (1.03–5.74), p = 0.044, respectively]. The risk of major vascular complications was lower via TC compared with Tsc, and Tcav and higher with Tcav compared with TF and Tsc. 30-day mortality was higher via Tsc compared with TF. Tsc was associated with higher risk of major or life-threatening bleeding compared with TF, and higher risk of stroke compared to TF and Tcav. Tcav had the highest risk of major vascular complications. Conclusion: In patients who underwent TF, Tsc, TC, or Tcav TAVR, Tsc had a higher rate of stroke compared to TF and Tcav, and major or life-threatening bleeding compared to TF. The rate of major vascular complications in Tcav was the highest among the four approaches.
