Is the arterial switch operation still a challenge in small centers

Objective: In the last years, major changes as regards timing for operation, surgical technique, and perioperative care determined a great improvement in the arterial switch operation (ASO) allowing excellent mid-term results in a few leading centers. This stimulated the widespread adoption of ASO as procedure of choice for transposition of the great arteries (TGA), even in small institutions. We reviewed our early experience with ASO in an attempt to evaluate its safety in a small center. Methods: Since April 1992, 39 consecutive patients underwent TGA repair by ASO in our department. There were 27 patients with simple TGA, 8 with TGA and VSD and 4 with Taussig-Bing heart and aortic coarctation. Median age and weight at operation
