Abstract

BackgroundThe aim of this work is to assess the uses of cardiac MR in evaluating post-operative congenital heart disease procedures and related complications.ResultsThis is a retrospective study done in between December 2015 and October 2017, including 71 patients with age ranging from 6 months to 33 years (mean age 16.75). All of the patients were referred for post-operative evaluation after echocardiographic examination to exclude post-operative complications and to plan for re-intervention if needed. Forty-three percent of patients suffered from post-operative complications. The most common congenital heart disease coming for post-operative evaluation was tetralogy of Fallot (TOF) which represented 32% of the cases. The most common post-operative complication in all procedures was pulmonary branch stenosis (12.6%) followed by patch dilatation (9.8 %) and right ventricular failure (7%). In 7 patients following TOF repair, there was aneurysmal dilatation of the patch with significant pulmonary regurgitation. The regurgitation fraction was less than 40% in 3 of them, while the remaining 4 cases showed regurgitation fraction of more than 40%, an indication for re-intervention.ConclusionMRI is an extremely useful imaging method for evaluation of normal and abnormal findings after surgical repair for congenital heart disease. It is effective in providing long-term surveillance and identifying post-procedural complications, which allowed us to further intervene on a timely manner when deemed necessary.

Highlights

The aim of this work is to assess the uses of cardiac Magnetic resonance (MR) in evaluating post-operative congenital heart disease procedures and related complications
We performed a retrospective analysis to evaluate the uses of cardiac MR in evaluating the postoperative congenital heart disease patient and demonstrate how cardiac MR contributed to the multidisciplinary evaluation of these patients
Magnetic resonance imager Both adults and children with congenital heart disease were scanned on a Philips Gyroscan Intera (1.5 T) whole-body MRI scanner housed in our radiology department

Summary

Introduction

The aim of this work is to assess the uses of cardiac MR in evaluating post-operative congenital heart disease procedures and related complications. Congenital heart disease (CHD) patient survival has greatly improved in recent decades, largely in part to technical advances related to diagnosis and treatment. Many of these patients have had palliative and corrective surgical procedures, creating a need for long-term surveillance so that anatomic parameters can be monitored and complications can be identified on a timely basis. Cardiac magnetic resonance (CMR) imaging is a non-invasive modality that has proven to be effective in determining both cardiac function and anatomy. It has become an integral and crucial part of ongoing follow-up of these patients because it. We performed a retrospective analysis to evaluate the uses of cardiac MR in evaluating the postoperative congenital heart disease patient and demonstrate how cardiac MR contributed to the multidisciplinary evaluation of these patients
