Background: Tetralogy of Fallot represents 7-10% of congenital heart diseases occurring in 0.5/1000 live births and is the second most common form of complex congenital heart diseases. The four elements of Tetralogy of Fallot: (a) sub-pulmonary obstruction resulting in (b) right ventricle hypertrophy, and (c) malalignment ventricular septal defect resulting in (d) apparent overriding of the aorta over both ventricles. Primary cardiac repair for Fallot Tetralogy patients includes right ventricular out flow tract widening interventions and ventricular septal defect closure. For such patients right ventricular assessment in the postoperative period is essential in aiding further management planning. The purpose of this study is to emphasize the role of cardiac MRI in functional and structural assessment of the right ventricle in Fallot tetralogy patients after surgical management. Results: The current study included 30 Fallot Tetralogy patients underwent cardiac MRI after surgical management. The majority of patients 26 out of 30 (86.6%) showed right ventricular dilatation. Four patients had right atrial dilatation. Less than one-third of patients 8 out of 30 (26.6%) had right ventricular systolic dysfunction. The majority of patients 29 out of 30 (96.6%) had main pulmonary artery regurgitation. More than half of the patients 18 out of 30 (60%) had main pulmonary artery stenosis. The majority of patients 25 out of 30 (83.3%) had right ventricular outflow tract late gadolinium enhancement and 18 patients (60%) had base of interventricular septal enhancement. Conclusions: MRI is an extremely useful imaging method for functional and structural assessment of the right ventricle after surgical repair of Fallot tetralogy patients with absence of ionizing radiation.
