Objective To examine changes of in-hospitalization mortality for arterial switch operation (ASO) for the patients with D-transposition of the great arteries (TGA) in our hospital. Methods We retrospectively analyzed the clinical data of 473 consecutive TGA patients undergoing ASO to assess temporal trends of in-hospital mortality between 2001 and 2012 year. The patients in every 2 years were brought together into a group. By this way, all the patients were divided into 6 groups. In risk-adjusted analyses, mortality of each group between 2001 and 2012 year were compared within the 6 groups. Results Among all the patients, 29 in-hospital deaths occurred. Between 2001 and 2012 year, the prevalence of preoperative factors-including age (P=0.13), gender (P=0.94), height (P=0.29), weight (P=0.21), combined with pulmonary hypertension (P=0.59), training for left ventricle (P=0.14), and anatomy of coronary arteries (P=0.27) did not significantly change. Crude mortality significantly decreased during that period (17.4% in the first group vs. 4.1% in the sixth group, P<0.001). Adjusted mortality also significantly became better in the ten years (the sixth group vs. the first group, odds ratio 0.098, 95% confidence interval, 0.018-0.550,P=0.01). Conclusion Between 2001 and 2012 year, the prevalence of risk factors among TGA patients undergoing ASO remains unchanged, but the in-hospital mortality substantial decreases.
