Abstract

Background: Tetralogy of Fallot (TOF) represents the prevailing form of cyanotic congenital cardiac disease. Cardiac magnetic resonance imaging (CMR) plays a crucial role in monitoring adult patients with congenital heart disease. Transthoracic echocardiography (TTE) is capable of providing the majority of the requisite data for sequential monitoring in patients with tetralogy of Fallot (TOF). Aim of the work: To investigate the respective contributions of cardiac magnetic resonance imaging and echocardiography in the evaluation of post-operative Fallot tetralogy, using a comparative analysis. Methodology: This study will be carried out on 30 cases of patients referred to the Heart Institute diagnosed by corrected tetralogy of Fallot by surgery, followed by echocardiography and cardiac MRI, as a comprehensive study between April 2022 and May 2023. Results: Our study revealed that patient with post-operative Fallot repair revealed the following complications by ECHO and CMRI: Dilated RV with variable degree of affected function, residual pulmonary stenosis with or without its branches, pulmonary regurgitation PR, tricuspid regurge TR as well as residual VSD shunt if present. Conclusion: Cardiac magnetic resonance imaging (CMR) offers a notable benefit compared to transthoracic echocardiography (TTC) due to its ability to precisely measure the size and function of both ventricles. CMR is widely regarded as the standard method for assessing volume and blood flow in cases with tetralogy of Fallot (TOF), as well as residual pulmonary stenosis.
