Abstract
<p>INTRODUCTION</p> <p>Vascular access complications (VAC) are the most common in-hospital adverse event following transcatheter aortic valve implantation (TAVI). Often, ileo-femoral VAC requires bail-out percutaneous interventions with either prolonged balloon inflation and/or stent implantation. The long-term outcomes of these procedures have not been characterized. We aim to assess the clinical and imaging outcomes of patients who underwent bailout percutaneous vascular interventions due to VAC following TAVI.</p> <p>METHODS</p> <p>Single-centre prospective study including all consecutive patients with a VAC following trans-femoral TAVI, between 2015-July 2023. VAC was defined as uncontrolled bleeding, acute occlusion or flow limiting stenosis of the femoral vessel leading to percutaneous treatment. Clinical and imaging follow-up was performed with bilateral arterial ultrasound (US) Doppler to assess patency and peak systolic velocity of common femoral arteries.</p> <p>RESULTS</p> <p>A total of 1518 patients underwent TF-TAVI, of which 7% (N=107) underwent concomitant ileo-femoral percutaneous angioplasty (PTA) intervention in the same day as TAVI. In patients submitted to PTA, 7 were treated to gain access for TAVI, and 100 (7%) were performed to treat vascular access complications. At a mean follow-up time of 23±3 months, 37 patients died (37%), 6 (16%) from in-hospital complications and 31 (84%) from non-vascular causes after discharge. From the surviving 63 patients (study group) – mean age 83±6 years-old, 29% male, 46% with previous peripheral arterial disease –, 24 underwent bilateral US. Unable to perform imaging on 39 patients due to geographical or mobility issues. At a mean follow-up time of 30±23 months, only 6 patients (10%) reported intermittent claudication, of which 4 (67%) had pre-TAVI symptoms. No patient had at rest symptoms or amputation history. All but one had patent vessel on US. The mean peak systolic velocity of the treated vessel and the contralateral vessel were 71.1±22.9cm/s and 73.1±23.8cm/s, respectively, with no statistically significant difference between them in each patient (mean difference 1.9±25.4, p=0.709). We found no statistically significant differences between peak systolic velocities between both vessels in each patient, accordingly with the treated vessel (Table 2).</p> <p>CONCLUSION</p> <p>This prospective study shows that patients submitted to percutaneous bailout iliofemoral interventions have a very low rate of lower limb adverse events with very good patency rates at mean follow up of 2.5 years.</p>
