MRI for the Functional Evaluation of Systemic Right Ventricle in TGA

ABSTRACT

During the past few decades, rapid development has been achieved in cardiac MRI. Cardiac MRI has also proven to be a useful tool in congenital heart disease, especially for the evaluation of its function and physiology. MRI can measure the ventricular volume, ventricular mass, flow velocity and flow volume accurately. Cardiac MRI has basically three-dimensional natures, so it is well suited for the measurement of functional parameters of right ventricle without geometrical assumption unlike echocardiography. MRI is becoming the useful imaging modality for the evaluation of systemic right ventricle which is often failed in the patients with unoperated or surgically corrected transposition of the great arteries.
