The missing vector - TactiFlex sensor enabled ablation catheter.

New ablation catheters have continuously developed to improve the safety and efficacy of ablation procedures. The TactiFlex Ablation Catheter Sensor Enabled (Abbott, Minneapolis, MN) is a novel open-irrigation radiofrequency ablation catheter that has contact force-sensing technology and flexible tip, allowing real-time contact force assessment with directionality. This case report reported a loss of contact force vector and directionality with the TactiFlex SE ablation catheter during de novo atrial fibrillation (AF) ablation.
