Feasibility and Procedural Considerations of Balloon-Expandable TAVR in Patients With Prior Endovascular Aortic Stent Grafts.

Objectives

To evaluate the feasibility and short-term outcomes of transcatheter aortic valve replacement (TAVR) using balloon-expandable Sapien valves in patients with prior endovascular aortic stent grafts.

Methods

We conducted a single-center, retrospective study of 23 patients with prior endovascular aortic stent grafts who underwent TAVR between 2012 and 2025 using Sapien platform balloon-expandable valves. Descriptive statistics and univariate logistic regression analysis were used to characterize and identify outcomes of peri-procedural complications.

Results

Transfemoral access was used in 87% of cases, and valve deployment was successful in all patients without aortic injuries or graft-related complications during the procedural and up to 30-day post-procedure period. Median length of stay was 3 days, and there were no deaths up to 30-days. Post-procedural events were infrequent and included new-onset atrial fibrillation (n = 2), transient hemodialysis (n = 1), pleural effusion (n = 1), and stroke (n = 1). In exploratory analyses limited by the small number of events, older age (OR 1.27, 95% CI 1.04-1.71) and higher baseline mean aortic-valve gradient (OR 1.24, 95% CI 1.06-1.76) were associated with periprocedural events.

Conclusions

The complications observed in our cohort are general outcomes associated with TAVR, instead of graft-associated outcomes. Balloon-expandable TAVR is technically safe and feasible in patients with prior endovascular aortic stent grafts when performed at experienced centers.
