Transposition of the great arteries (TGA) is a lethal condition without intervention. Cross-sectional echocardiography is the diagnostic investigation of choice. Intravenous infusion of prostaglandin is employed to maintain ductal patency and allow mixing of blood, thus improving tissue oxygenation. Balloon atrial septostomy is recommended once the diagnosis is made. The ...
Murakami T - - 2000
BACKGROUND: Although the arterial switch operation has become the standard surgical procedure for treatment of complete transposition, postoperative problems have not been fully appreciated. One such problem may be the postoperative function of great arteries that are manipulated radically. METHODS: The diameters at four levels of the aorta were measured ...
