Preoperative factors
The mean age (in years) of the study population was 29.68 ± 12.37 for Group 1 and 28.57 ± 11.29 for Group 2. In Group 1, 10 (45.4%) patients were male, and 12 (55.6%) patients were female; in Group 2, 11 (50.0%) patients were male, and 11 (50.0%) patients were female. No statistically significant (p > 0.05) differences in patient characteristics such as ejection fraction, LA diameter, pulmonary artery systolic pressure (PASP) and atrial fibrillation was found between these two groups.
