Left ventricular function after arterial switch operation as assessed by two-dimensional speckle-tracking echocardiography in patients with simple transposition of the great arteries

ABSTRACT

Background: The late postoperative course for children with transposition of the great arteries [TGA] with an intact ventricular septum [IVS] is very important because the coronary arteries may be at risk of damage during arterial switch operation [ASO]. We sought to investigate left ventricular function in patients with TGA/IVS by echocardiography
