ABSTRACT
OBJECTIVES: Transfemoral (TF) access for transcatheter aortic valve replacement (TAVR) may be challenging in patients with peripheral arterial disease (PAD). Alternative access through intra- and extrathoracic approaches can be performed. Recently, a facilitated TF access strategy, which involves the use of intravascular lithotripsy to optimize the iliofemoral arteries prior to TAVR, has been utilized. The aim of this study was to evaluate early outcomes of facilitated TF access compared to alternative access in patients with severe PAD.
METHODS: Patients with severe PAD who underwent TAVR from 2021 to 2023 were included in the study and were divided into 2 groups: facilitated and alternative access. The primary endpoint was a composite of mortality, stroke, and vascular complications. Mortality was evaluated in-hospital and at 1-month follow-up.
RESULTS: Of 150 TAVR patients with severe PAD, 24 underwent facilitated access. Baseline characteristics including age, Society of Thoracic Surgeons score, and mean gradients were similar between the 2 groups. The most common alternative access was transsubclavian, followed by transcarotid. Primary outcomes were numerically higher in the alternative access group (14% vs 8%); however, this did not reach statistical significance (P = .49). General anesthesia use and postoperative length of stay were higher in the alternative access group. Postoperative and 1-month mortalities were similar between the 2 groups.
CONCLUSIONS: Although the primary endpoint did not reach statistical significance, the numerical trend toward better outcomes in the facilitated TAVR group indicates a potential advantage. Large-scale prospective studies are required to determine the appropriate access strategy for TAVR in patients with severe PAD.
