Is catheter-tissue contact force value important for ablation of ventricular arrhythmias originating from the left ventricular papillary muscles?

ABSTRACT:

Background

Good catheter-tissue contact is mandatory to create effective ablation lesions. The minimal contact force value for ablation of arrhythmias originating from the left ventricle is 8.0-10.0 grams but is not known for arrhythmias arising from papillary muscles.

Purpose

To analyze contact force values during successful ablation procedures of arrhythmias originating from the left ventricular papillary muscles.

Methods

24 consecutive patients (mean age 57.9 ± 11.9 years, 16 males) underwent ablation of premature ventricular complexes originating from left ventricular papillary muscles with the use of CARTO electro-anatomical system and intracardiac echocardiography.

Results

Acute complete abolition of ventricular ectopy was obtained in 23 (96%) patients. T
