Why the study?
Bovine aortic arch is the most common arch variant and represents challenging anatomy for cerebral embolic protection device insertion during TAVR.
Is Sentinel Cerebral Protection System insertion feasible and safe in patients with bovine aortic arch anatomy undergoing TAVR compared to non-bovine anatomy?
Population
165 adult patients undergoing transfemoral TAVR
Comparison
Bovine aortic arch vs non-bovine aortic arch

Sentinel insertion remains safe in bovine arch TAVR despite lower two-filter success; leaves open need for anatomy-specific device refinements.
Is Sentinel Cerebral Protection System insertion feasible and safe in patients with bovine aortic arch anatomy undergoing TAVR compared to non-bovine anatomy?
Sentinel cerebral embolic protection device insertion is safe in patients with bovine aortic arch anatomy undergoing TAVR, though successful two-filter deployment is significantly lower than in non-bovine anatomy.
