Objective: To review and analysis the surgical results of 113 arteries Switch operations.
Methods: One hundred and thirteen patients had been repaired by arterial Switch operation from January 2001 to December 2005. There were 60 patients with transposition of the great arteries and intact ventricular septum (TGA/IVS), 53 patients with transposition of great arteries and ventricular septal defect (TGA/VSD). The lowest body weight was 2.3 kg, and the youngest operative age was 6 h. The arteries Switch operation was performed underwent deep hypothermic circulation arrest and low-flow perfusion.
Results: The total mortality was 9.7%. There were 5 deaths among TGA/IVS (8.3%), 6 deaths among TGA/VSD (11.3%). Following improvement of surgical technique, post-operative management and cardiopulmonary bypass, the operative mortality was decreased from 16.6% to 5.5%.
Conclusions: The main reason for operative mortality was abnormal coronary arteries. The incidence of abnormal coronary arteries was high at TGA/VSD. The surgical results was not infected by the position of great arteries. The low cardiac output was appeared if the ratio of left ventricular pressure and right ventricular pressure less than 0.6.
