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

National and Kapodistrian University of Athens

Status: Unknown

Conditions: Atrial Fibrillation

Treatments: Procedure: Pulmonary vein isolation

Study type: Observational

Funder types: Other

Identifiers

NCT02801175

1/13.6.2016

Details and patient eligibility

About

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).

Enrollment: 40 estimated patients
