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

National and Kapodistrian University of Athens40 enrolled

Overview

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).
