Left atrial functions in the early period after cryoballoon ablation for paroxysmal atrial fibrillation

In patients with paroxysmal atrial fibrillation (PAF), functional changes are observed in the left atrium (LA) after pulmonary vein isolation (PVI) procedure. Although previous studies have investigated the altered mechanical functions of the LA with radiofrequency (RF) ablation, changes in the LA functions in the early period after cryoablation (CB‐2) have not been clearly demonstrated. This study aims to explore the early periodical changes in mechanical functions of the LA in patients with PAF who underwent CB‐2 based ablation through the help of echocardiographic methods which contain Doppler and strain parameters.
