QDOT MICRO™ versus THERMOCOOL^® SMARTTOUCH™ and THERMOCOOL SMARTTOUCH^® Surround Flow in radiofrequency ablation of paroxysmal atrial fibrillation.

ABSTRACT: Aim: The objective of this study was to indirectly compare QDOT MICRO™ (QDOT), Thermocool^® SmartTouch™ (ST) and Thermocool^® SmartTouch^® Surround Flow (STSF) to treat paroxysmal atrial fibrillation. Methods: Differences in baseline characteristics between study cohorts were reduced by reweighting patients using inverse probability of treatment weighting. The primary outcome was procedure time. Secondary outcomes were fluoroscopy time, clinical success at 12 months, and rhythm monitoring-adjusted recurrence. Results: QDOT was associated with significantly faster mean procedure and fluoroscopy time, and significant improvement in the rate of recurrence compared with pooled ST/STSF. No difference was observed for clinical success at 12 mont
