Determining the Safety of Radiofrequency Ablation in Cardiovascular Implantable Electronic Devices.
Radiofrequency catheter ablation (RFCA) is an effective treatment for arrhythmias. The effects of RFCA on cardiovascular implantable electronic devices (CIED) function have varied. We aim to study the effect of RFCA on device parameters and clinical outcomes in patients with CIED. We conducted a single-center retrospective cohort study between 2011 and 2018. Generator and lead parameters were compared pre- and post-ablation using paired sample t-test. The median follow-up interval for documentation of procedure-related complications and clinical outcomes was 8 weeks. We identified 119 eligible patients; whose mean age was 64.5 ± 11.91 years and 22 (18.4%) were females. Types of CIED include single-chamber implantable cardioverter defibrillators (8.93%), dual-chamber implantable cardioverter defibrillators (41.96%), and either dual-chamber or biventricular pacemakers (44.54%). Arrhythmias for which patients underwent RFCA include atrial fibrillation/atrial tachycardia (15.22%), atrial flutter (38.14%), atrioventricular node reentrant tachycardia (13.56%), and premature ventricular complex or ventricular tachycardia (20.34%). No statistically significant difference was observed in pre- and post-ablation: (1) atrial sensing thresholds, pacing thresholds, lead impedance; (2) right ventricle sensing and pacing thresholds; and (3) left ventricle pacing threshold and impedance. A decrease in right ventricle impedance after ablation (549.77 ± 173 ohm vs 507.40 ± 129.0 ohm, P-value
