Diastolic ventricular interaction in patients after atrial switch for transposition of the great arteries: A speckle tracking echocardiographic study

Background We tested the hypothesis that diastolic ventricular interaction occurs after atrial switch operation for transposition of the great arteries (TGA) and that subpulmonary LV diastolic function is influenced by septal geometry. Methods Twenty-nine patients (male 19) after atrial switch operation for TGA aged 20.8±4.1 years and 27 healthy controls were studied. Two-dimensional longitudinal systolic strain, systolic (SRs), early diastolic...
