Abstract
Background: Tetralogy of Fallot (TOF), the second most prevalent kind of complicated congenital heart disease (CHD), accounts for 7-10% of CHD and affects 0.5/1000 live births. After surgical care, cardiac magnetic resonance imaging (MRI) may be used to assess the right ventricle in TOF.The aim of the current study is to evaluate the role of cardiac MRI in functional and structural assessment of the right ventricle in TOF patients after surgical management. Patients and methods: The study was conducted on 30 patients of variable age groups that were collected from our institute, who were referred to the radio diagnosis department after TOF operations and underwent cardiac MRI. Full structural and functional assessment of the right ventricle could be done using various MRI pulse sequences as well as the late gadolinium enhancement protocol. Results: Of the included 30 patients,26 (86.6%) showed right ventricular dilatation. Right ventricular end diastolic volume index: Left ventricular end diastolic volume index (RVEDVI: LVEDVI) ratio was 1.84:1. Four patients had right atrium dilatation. Of the 30 participants, 8 (26.6%) had RV systolic dysfunction with mean ejection fraction (EF) was 51.83% (SD 9.39). Out of 30 TOF cases, 29 (96.6%) had main pulmonary artery (MPA) regurgitation, and 18 (60%) had right ventricular outflow tract obstruction (RVOTO). Conclusions: MRI is an extremely useful imaging method for the functional and structural assessment of the right ventricle after surgical repair of TOF.
