Peds/CHD Pre-Conference Course 03 - Practical Imaging Suggestions for Pediatric & CHD CMR-How to image Tetralogy with CMR

Video Transcription

Video Summary

Cardiac MRI is essential in follow-up of repaired Tetralogy of Fallot because pulmonary regurgitation can cause progressive right ventricular dilation, dysfunction, and failure. CMR provides reproducible measurements of ventricular volumes and function, quantifies regurgitant fraction, and evaluates the RV outflow tract, pulmonary arteries, coronaries, and myocardial fibrosis. Imaging plane and segmentation method should be consistent to maximize reproducibility. RVOT anatomy helps determine candidacy for surgical or transcatheter pulmonary valve replacement. Late gadolinium enhancement may indicate worse disease progression and outcomes.
