After Arterial Switch Surgery Myocardial Performance Index Left Ventricular Function does it Provide as much Information as a Cardiac MRI?

Objectives: In this study, a comparison of cardiac magnetic resonance imaging (MRI) and simultaneous transthoracic echocardiography data were obtained from patients with great artery transposition (TGA), who underwent arterial switch operation (ASO) surgery.In to discover the most effective and optimal viewing method during long-term follow-ups. Materials and Methods:This retrospective cohort included 20 TGA patients (16 male, 4 female), which had ASO surgery.Along with cardiac MRI and transthoracic echocardiography data were obtained from the images.The mean age was 93.00±29.82months (60-144).Seventeen patients had TGA only.However, 3 patients with TGA included an existing ventricular septal defect.Results: We showed a meaningful correlation between echocardiographic variables (left ventricle dilatation of the left ventricle function of the aorta failure, myocardial performance index) and MRI parameters (ejection fraction of left ventricle dilatation of the left ventricle function of the aorta insufficiency).
