Echopac software version 112

Transthoracic echocardiography was performed within 1 week before the procedure by a single experienced investigator by using an Epiq 7G (Phillips Academy, Andover, Massachusetts, USA) with a 2.5-MHz probe in the two-dimensional (2D), M, and Doppler modes. The routine evaluation consisted of the measurements of the heart chamber dimensions and the assessment of valvular function and myocardial contractility. The loops of transthoracic echocardiography were retrieved and analyzed for atrial function by one of the coauthors (UP) experienced in the echocardiography analysis, who was blinded for those general clinical data of the patients including BMI. Speckle-tracking imaging with the LA and RA strain analysis was performed by using EchoPAC Software version 112.0.0 (GE Healthcare, Horten, Norway). The five-wall model for LA segmentation corresponding with a six-segment division in apical two-chamber (2Ch) and four-chamber (4Ch) projections was used during the LA and RA strain analysis (18 (link)).

Transthoracic echocardiography was performed 1 day before and 6 months after the procedure by a single experienced investigator using an Epiq 7G (Philips, Andover, MA, USA) with a 2.5-MHz probe in 2D, M, and Doppler modes. The routine check-up consisted of measurements of the heart chamber dimensions, the assessment of valvular function and myocardial contractility.
Transoesophageal echocardiography was performed in all of patient 24 h before the procedure to exclude the potential presence of an LA appendage thrombus.
Speckle-tracking imaging with LA strain analysis was performed using EchoPAC Software version 112.0.0 (GE Healthcare, Horten, Norway). The five-wall model for left atrium segmentation corresponding with a six-segment division in apical two- (2Ch) and four-chamber (4Ch) projections was used during the LA strain analysis [4 (link)].
