What surgical method is used to correct transposition of the great arteries?

Transposition of the great arteries (TGA) is a congenital heart defect where the two main arteries leaving the heart are reversed, leading to a separation of systemic and pulmonary circulation. The surgical methods used to correct TGA aim to reestablish the proper anatomical configuration of the heart and great vessels.

The arterial switch procedure is the primary surgical intervention for TGA. This technique involves switching the aorta and the pulmonary artery back to their normal positions, allowing for proper circulation. This method is favored because it restores normal physiology and maintains the patient's ability to grow and exercise without significant long-term complications.

The Mustard-Senning procedure, while initially used, is now less common for TGA management, as it involves creating a baffle to redirect blood flow rather than directly correcting the vessel positions. This technique is generally applied more in cases of atrial switch operations for other forms of congenital defects.

The double-switch procedure can be an option in specific cases, especially when there is concurrent issues such as double inlet left ventricle or other complexities. However, it is not the standard approach for isolated TGA.

The Rastelli procedure is another surgical technique but is typically reserved for situations combining TGA with ventricular outflow obstruction, such as aortic sten
