Surgical Versus Interventional Treatment of Major Access Site Complications During Transfemoral TAVI Procedures at a Large Volume Center.

Purpose: Access-related vascular complications in transfemoral transcatheter aortic valve implantation (TAVI) can be treated endovascularly or surgically. The aim of this study was to evaluate the short- and long-term outcomes of endovascular treatment compared with surgical repair for access-related vascular complications.

Methods: This retrospective study was performed from January 1, 2018, to December 31, 2020. All transfemorally treated TAVI patients in whom a surgical or endovascular treatment for an access site complication was needed were included. The primary outcome was the need for any related vascular re-operation.

Results: In total, 1219 transfemoral TAVI procedures were conducted during the study period. 19 patients suffered an access complication requiring endovascular treatment, while 54 patients required surgical repair. No differences were seen with regard to re-operations (endovascular 15.8% vs surgical 14.8%; p=0.919), wound infections (endovascular 0% vs surgical. 11.1%; p=0.129), and wound healing disorders (endovascular 15.8% vs surgical 29.6%; p=0.237). Patients undergoing endovascular treatment were discharged earlier (endovascular 11.2 vs surgical 14.9 days; p=0.028). After surgical repair, patients received significantly more blood transfusions than endovascularly treated patients (endovascular 1.00 vs surgical 3.1 red blood cell concentrate bags; p<0.001). No differences were found regarding the new onset of walking pain, rest pain, and ischemic ulcers during follow-up.

Conclusion: In this retrospective cohort, endovascular treatment of access-related vascular complications of transfemoral TAVI procedures was safe and feasible. During the hospital stay, endovascularly treated patients received fewer blood transfusions and were discharged faster than surgically treated patients. No differences regarding clinical outcomes and re-intervention rates were seen during the follow-up.Clinical ImpactGiven the in this retrospective study demonstrated safety and feasibility of endovascular treatment for major access-related vascular complications, along with the in-hospital benefits and absence of follow-up disadvantages compared to surgical treatment, endovascular treatment should be considered in cases of major access-related vascular complications in transfemoral TAVI patients.
