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\u20102) 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\u20102 based ablation through the help of echocardiographic methods which contain Doppler and strain parameters.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>Consecutive 77 patients (mean age: 57.5 \u00b1\u00a0\u00a011.2; 57% men) with PAF underwent CB\u20102 were prospectively analyzed. All patients were in sinus rhythm before and after the procedure.
