Comparative study of rapid and long-term two-stage arterial switch operation in treatment of transposition of the great arteries with intact ventricular septal / 中国胸心血管外科临床杂志

ABSTRACT

@#Objective    To summarize the experience of surgical treatment of transposition of the great arteries with intact ventricular septal (TGA-IVS) after left ventricular regression by comparing the characteristics of rapid and long-term two-stage arterial switch operation (ASO). Methods    Forty-one patients who were mainly diagnosed with TGA-IVS from January 2007 to January 2019 and underwent two-stage ASO were included. They were divided into a rapid two-stage ASO group (19 patients) and a long-term two-stage ASO group (22 patients) according to the interval of left ventricular training surgery and ASO. The clinical effectiveness of the two groups was compared. Results    There was a statistical difference in age, body weight, blood oxygen saturation before ASO, end diastolic diameter of left ventricle before training, and thickness of posterior left ventricular wall before ASO (P<0.05). Children older than 1 year was an independent risk factor for long-term two-stage ASO. Conclusion    Long-term two-stage ASO is suitable for children who are older than 1 year and who have severe left ventricular regression.
