Effect of Left Atrial Ablation on Left Atrial Appendage Emptying Flow Velocity

Conditions
Atrial Fibrillation
Interventions
Procedure: Pulmonary vein isolation
Registration Number
NCT02801175
Lead Sponsor
National and Kapodistrian University of Athens
Brief Summary

Consecutive patients with paroxysmal AFib scheduled to undergo pulmonary vein isolation either with radiofrequency (RF) or cryoballoon will be included. Left atrial appendage emptying flow velocity (LAA-EFV) will be measured with transesophageal echocardiography (TEE) immediately before and following left atrial ablation (1 month post). The change in LAA-EFV will be compared between the two groups (RF versus Cryo).
