Lesion Contiguity in Very High Power-short Duration Ablation

No results posted yet for this study

Summary

This observational trial investigates the effect of very high power-short duration radiofrequency ablation on lesion contiguity as assessed by late gadolinium enhancement cardiovascular magnetic resonance (LGE-CMR). Patients with paroxysmal or early persistent atrial fibrillation (AF) scheduled for pulmonary vein isolation (PVI) undergo point-by-point ablation using the QDOT micro catheter applying Qmode+ (90W over 4 seconds). All patients receive an LGE-CMR 3 months after the procedure for ablation lesion assessment. Contiguity of LGE-CMR-detected ablation lesions will be compared with a matched control group of patients that have undergone PVI accomplished by ablation index-guided ablation with 40 W following the CLOSE protocol.
