Abstract

Background: The operative procedures for correction of tetralogy of Fallot (TOF) concentrates on the impact of pulmonary valve regurgitation (PR) on the function of right ventricle (RV) pointing to alleviating right ventricle outflow tract (RVOT) narrowing, and minimizing the PR degree at the same time, closing ventricular septal defect (VSD). Various complications could be encountered after TOF repair as; PR, dilated RV with/without impaired function, RVOT residual obstruction/ dilatation, residual VSD, tricuspid regurge (TR), aortic root dilatation with/without regurge and significant difference in differential pulmonary flow. Objective: Address the most common complications that could be encountered following TOF surgical repair, the role of cardiac magnetic resonance imaging (CMRI) in evaluation of these complications and summarize them as a checklist for reporting post-operative cases. Methods: A retrospective study involved 116 patients, their ages ranging from two years to eighteen years (Mean ± standard deviation (SD)=8.1 ± 4.5) from March 2021 to May 2023, evaluated for possible complications following TOF operative repair by MRI. Results: 105 patients had dilated RV. 31 patients had impaired function. All patients had PR. 12 had severe TR, 18 had aortic regurgitation. 18 had residual VSD. 7 had residual RVOT stenosis, 5 had aneurysmally dilated RVOT. 39 patients had significant differences in differential pulmonary flow. Conclusions: MRI is critical for evaluation of post TOF repair patients and possible complications. CMRI is accurate in quantifying PR, RV size and function and evaluating other possible important complications related to RVOT, pulmonary arterial diameters and differential flow, VSD closure and LV function and size as well.
