Overview

Cardiac MRI is noninvasive imaging for the evaluation of cyanotic congenital heart disease and determines myocardial function and area of fibrosis, the direction of flow and velocity across the palliative shunt and valves, the anomaly of connection of arteries and veins and correlation of anatomic and morphologic ventricles with great arteries in complex congenital heart disease.

MRI

A cardiac MRI is a useful tool for diagnostic of cyanotic congenital heart disease. Findings on a cardiac MRI in cyanotic congenital heart disease include:^[1]

Assessment of turbulent flow in stenotic or regurgitant valves, septal defect, ventricular mass, chamber volume, ejection fracture
Assessment of anatomic and physiologic information of simple and complex congenital heart lesions
Determination of blood velocity and blood flow gradients across the shunt and direction of blood flow
Determination of the flow and anatomic relation of aorta and pulmonary arteries
Evaluation of right ventricular dysfunction in patients with right ventricular obstruction and study the left ventricle of patients with transposition of great arteries

Recommendation for Cardiac MRI(CMR)imaging in congenital heart disease according to 2018AHA/ACC Guideline

Class OF Recommendation	Level Of Evidence	Recommendations
।	B	Serial CMR for assessment of right ventricle enlargement and dysfunction in congenital heart disease who are at risk
॥a	C	Initial evaluation and serial assessment of congenital heart disease based on complexity and anatomy
