  "abstract": "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.\n\nMethods: 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.\n\nResults: 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.\n\nConclusions: 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.",
