Key result
Catheter ablation successfully eliminated atrial tachycardia originating from the tip of the right atrial appendage despite difficulties in catheter manipulation and achieving adequate power.
Case Report (n=1)
Catheter ablation is feasible and effective for eliminating atrial tachycardia originating from the tip of the right atrial appendage, despite anatomical challenges.
Supports feasibility of RAA tip ablation despite technical hurdles; leaves open reproducibility, safety, and durability in larger cohorts.
Right atrial appendage tachycardia is not common and can be eliminated by catheter ablation with a high success rate and low recurrence rate. However, the structural properties of the atrial appendage, including blind-ended structure, abundant trabeculations, and reduced wall thickness could make the procedure of catheter ablation difficult, especially if the focus is at the tip of atrial appendage. We describe a case of atrial tachycardia originating from the tip of the right atrial appendage that was eliminated by catheter ablation in spite of some difficulties in manipulation of the catheter and achieving adequate radiofrequency power.
