Objectives: To assess the long term outcomes of iliofemoral stents after Trans-catheter Aortic Valve Replacement (TAVR).
Background: Vascular access site and access-related complications present a common problem during trans-femoral TAVR. Although stent placement in the common femoral artery (CFA) is a commonly used solution for such complications, its long term safety and efficacy are not well defined.
Methods: From a single center cohort of 648 patients who underwent TAVR at Sheba Medical Center in Israel, 90 patients suffered an access-related complication requiring intervention. Of these, 56 patients underwent common femoral artery (CFA) stent insertion. Patients were assessed by history and physical examination, underwent follow-up duplex ultrasound velocity evaluation of the common femoral stent and a bilateral Doppler ultrasound arterial exam, including Ankle-brachial index (ABI) measurement.
Results: Mean follow up time was 676 days. None of the 56 patients needed a vascular intervention of the affected limb, and none suffered from a relevant limb claudication. There was no difference between pre-procedural and post procedural ABI values (1.2±0.14 and 1.19±0.24, respectively), and only one patient demonstrated a significant decrease in the ABI associated with medium severity CFA stent stenosis that did not require further intervention. There were no stent fractures.
Conclusions: Ilio-femoral stent insertion is a safe and efficacious treatment for vascular access site and access-related complications during trans-femoral TAVR.
