Key result
Catheter ablation of the critical isthmus and CTI sustainably terminated atrial flutter in a patient with previous tricuspid valve-in-valve replacement.
Why the study?
The feasibility and safety of cavo-tricuspid isthmus-dependent atrial flutter ablation after transcatheter tricuspid valve-in-valve replacement had not been reported.
Case Report (n=1)
This case provides the first reported evidence that CTI-dependent atrial flutter ablation is feasible and safe after tricuspid valve-in-valve replacement.
Supports feasibility of CTI ablation after tricuspid ViV; leaves open need for larger studies on safety and efficacy.
A patient with previous transcatheter tricuspid valve-in-valve replacement underwent catheter ablation for symptomatic atrial flutter. An incisional and cavo-tricuspid isthmus (CTI) dependent right atrial flutter was confirmed. Ablation of the critical isthmus at the lateral right atrial wall and CTI ablation sustainably terminated the flutter. This case highlights the feasibility and safety of CTI-dependent atrial flutter ablation after tricuspid valve-in-valve replacement, which has not been reported so far. Keywor

Suna et al. (2023) conducted a case report in Symptomatic atrial flutter after transcatheter tricuspid valve-in-valve replacement (n=1). Catheter ablation was evaluated on Termination of flutter. Catheter ablation of the critical isthmus and CTI sustainably terminated atrial flutter in a patient with previous tricuspid valve-in-valve replacement.
