Key result
CARTO VIZIGO sheath delamination during AF ablation causes a thromboembolic transient ischemic attack.
Why the study?
A thromboembolic event due to delamination of a steerable guiding sheath during atrial fibrillation ablation indicates a device deficiency in structural integrity.
Case Report (n=1)
This case highlights the rare but serious risk of structural delamination of steerable guiding sheaths during atrial fibrillation ablation, emphasizing the need for procedural vigilance regarding device integrity to prevent thromboembolic complications.

Device delamination caused TIA in one AF ablation; leaves open broader safety implications for CARTO VIZIGO sheath.
We report a case of transient ischemic attack due to a thromboembolic event secondary to delamination of the steerable guiding sheath, CARTO VIZIGO™ (J&J MedTech, New Brunswick, NJ, USA), indicating a device deficiency in structural integrity. This case illustrates an unforeseen device-related complication, emphasizing the importance of heightened vigilance for this potential complication during catheter ablations incorporating this sheath.

Golzarian et al. (2026) conducted a case report in Atrial Fibrillation (n=1). CARTO VIZIGO steerable guiding sheath was evaluated on Transient ischemic attack due to sheath delamination. Structural delamination of the CARTO VIZIGO steerable guiding sheath during atrial fibrillation ablation resulted in a thromboembolic transient ischemic attack.
