First application of the varipulse™ catheter for linear ablation in atrial fibrillation: a case report.

ABSTRACT:

Background

This case report documents the application of the Varipulse™ catheter in linear ablation, offering a successful exploratory experience for the linear ablation of atrial fibrillation.

Case presentation

The patient exhibited signs of AF. After successful completion of pulmonary vein potential isolation and mitral isthmus line ablation, atrial fibrillation was converted into atrial flutter. Integrating the atrial flutter's activation sequence with coronary sinus electrode mapping, we localized the reentrant circuit to the tricuspid isthmus and the surgical incision. Targeted ablation was sequentially performed at these identified sites, and subsequently, the patient's rhythm converted to sinus rhythm.

Discussion

Linear ablation for AF faces substantial technic
