Effect of Left Atrial Ablation on Left Atrial Appendage Emptying Flow Velocity (ABLAA-FV)

June 13, 2016 updated by: Spyridon Deftereos, National and Kapodistrian University of Athens

Differential Effect of Radiofrequency and Cryoballoon Ablation on Left Atrial Appendage Emptying Flow Velocity

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).
