Left Bundle Branch Ablation Guided by a Three-Dimensional Mapping System: A Novel Method for Establishing a Heart Failure Animal Model

Announcing a new article publication for Cardiovascular Innovations and Applications journal.  Few studies have been conducted to establish animal models of left bundle branch block by using three-dimensional mapping systems. This research reported by this article was aimed at creating a canine left bundle branch block model by using a three-dimensional mapping system.

A three-dimensional mapping system was used to map and ablate the left bundle branch in beagles. Ten canines underwent radiofrequency ablation, among which left bundle branch block was successfully established in eight, one experienced ventricular fibrillation, and one developed third-degree atrioventricular block. The maximum HV interval measured within the left ventricle was 29.00 ± 2.93 ms, and the LBP-V interval at the ablation site was 20.63 ± 2.77 ms. The LBP-V interval at the ablation target was 71.08% of the maximum HV interval.

This three-dimensional mapping system is a reliable and effective guide for ablation of the left bundle branch in dogs.

Experience in Application of a Three-Dimensional Pulsed Field Ablation System Integrating Mapping and Ablation

Announcing a new article publication for Cardiovascular Innovations and Applications journal. Pulsed field ablation (PFA), a promising technology for ablating arrhythmias, has significantly better efficiency and potentially greater safety than traditional ablation techniques using thermal injury. However, most clinical research on PFA for ablation to date has used basket- or flower-shaped catheters, thus requiring a large introducing sheath and catheter location under fluoroscopic guidance. The authors of this article describe initial experiences with using a three-dimensional PFA system integrating mapping and ablation, and an annular catheter.
