Abstract

Pulmonary veins isolation usually requires a multielectrode catheter for mapping in addition to the ablation catheter. We describe our experience with a new multipolar catheter designed for simultaneous mapping and ablation (MESH, Bard). We tested the catheter in 15 patients (mean age 61.1 +/- 7.9; eight men) scheduled for paroxysmal atrial fibrillation ablation. The catheter was positioned in front of the pulmonary vein ostia. A pulmonary vein potential was demonstrated in 63.5% of the veins, which were disconnected with a mean of 1.6 radiofrequency applications with a mean time of 351 +/- 125.8 s (range 180-650) for each vein. Mean procedural time was 93 +/- 17.1 min (range 65-120), and fluoroscopy time was 13.7 +/- 4.0 (range 5-15) min. No complications occurred during and after or procedures. Pulmonary veins disconnection with MESH ablator catheter is feasible with short procedural and X-ray exposure time. Further studies are needed to compare this new device to standard multipolar mapping catheters in order to evaluate its ability to correctly identify pulmonary vein potentials and to compare its safety and efficacy.

Atrial Filbrillation

Atrial fibrillation refers to the abnormal heart rhythm characterized by rapid and irregular beating of the atria. Here is the latest research.

Arrhythmia

Arrhythmias are abnormalities in heart rhythms, which can be either too fast or too slow. They can result from abnormalities of the initiation of an impulse or impulse conduction or a combination of both. Here is the latest research on arrhythmias.

Atrial Fibrillation

Atrial fibrillation is a common arrhythmia that is associated with substantial morbidity and mortality, particularly due to stroke and thromboembolism. Here is the latest research.
