Temperature-controlled Ablation Versus Conventional Ablation for Pulmonary Vein Isolation in the Treatment of AF: A Systematic Review and Meta-Analysis.

ABSTRACT:

Background

This study compared the efficacy and safety of temperature-controlled and conventional contact-force-sensing radiofrequency ablation catheters for pulmonary vein isolation (PVI) in AF.

Methods

Seven studies (1,138 patients) were included. Randomised controlled trials and observational (single-arm and two-arm) studies that reported freedom from AF ≥3 months after PVI with temperature-controlled radiofrequency ablation catheters (Biosense Webster QDOT MICRO operating in QMODE or Medtronic DiamondTemp) were included.

Results

Freedom from AF at a mean (± SD) follow-up of 9.0 ± 3.6 months did not differ significantly between temperature-controlled and conventional ablation (OR 1.22; 95% CI [-0.79, 1.64]; p=0.24). Total procedure duration (-13.5 minutes; 95% CI [
