Key result
The arterial-arterial rail technique is a recommended strategy for post-TAVI paravalvular leak closure when standard approaches are ineffective, enhancing success rates with lower-profile plug devices.
Why the study?
Post-TAVI paravalvular leak greater than mild increases mortality, heart failure hospitalizations, and reintervention, yet closure is more challenging than in surgical valves.
The arterial-arterial loop technique is a recommended strategy to ensure procedural success for paravalvular leak closure after TAVI when standard approaches fail.
A-A rail may aid post-TAVI PVL closure; leaves open need for prospective validation before wider use.
More than mild paravalvular leak (PVL) following transcatheter aortic valve implantation (TAVI) is associated with a twofold increase in all-cause mortality, heart failure hospitalizations, and the need for reintervention. Successfully addressing PVL in TAVIs is more challenging than in surgical valves. The arterial-arterial (A-A) rail technique emerges as a valuable strategy for post-TAVI PVL closure, enhancing success rates by enabling the effective use of lower-profile vascular plug devices. When standard approach is ineffective, generating an A-A loop for post-TAVI PVL closure is probably the most recommended strategy to ensure procedural success.

Flores‐Umanzor et al. (2024) conducted a review in Paravalvular leak following transcatheter aortic valve implantation (TAVI). Arterial-arterial (A-A) rail technique was evaluated. The arterial-arterial rail technique is a recommended strategy for post-TAVI paravalvular leak closure when standard approaches are ineffective, enhancing success rates with lower-profile plug devices.
