Patients with transposition of the great arteries treated with arterial switch repair: Long-term results

Abstract

Background: The preferred surgical technique for great artery transposition is arterial switch surgery. Its result is not without unfavourable events, nevertheless. The work's objective was to assess the incidence and outcome of neo-pulmonary and neo-aortic valve disorders, incidence of coronary disease and branch pulmonary artery disease. Also to assess systemic ventricular function. Methods: A retrospective study of one hundred people with large vessel transposition (D-transposition) (TGA) was conducted among those who underwent ASO with LeCompte Manoeuvre. All patients were subjected to electrocardiogram, full trans thoracic echocardiographic examination, peripheral pulmonaries and coronary arteries and computed tomography/ magnetic resonance imaging. Results: There was no correlation between left ventricle global longitudinal strain (LVGLS) and age at time of ASO. Age and sex did not significantly correlate with LVGLS. There was significant relation between LVGLS and type of TGA, ventricular septal defect (VSD). Forty patients developed significant pulmonary stenosis (PS), 16 patients have moderate to severe aortic regurgitation, 21 patients have right ventricle (RV) dilatation, 6 patients have RV systolic dysfunction, 4 patients have LV systolic dysfunction, and one patient has significant aortic root dilation. Between the groups under study, there is a substantial difference (p
