CT; LAEF, left atrial ejection fraction; LAVI_max, the index of maximum left atrial volume; LAVI_min, the index of minimum left atrial volume; LAV_max, maximum left atrial volume; LAV_min, minimum left atrial volume; MOD, modified Simpson's rule; PTSMA, percutaneous transluminal septal myocardial ablation.
