Foundations of CMR: Level 1 Virtual Course-SESSION 7: EMERGING ROLE OF CMR: CHD & VALVES

Video Transcription

Video Summary

The session focused on the role of cardiac MRI (CMR) across congenital and valvular heart disease, followed by an interactive quiz.<br /><br />Dr. Supriya Jain opened with pediatric congenital heart disease (CHD), describing CMR as a noninvasive “one-stop shop” for anatomy, function, flow, shunt quantification, and tissue characterization without radiation. She highlighted its value in aortic arch anomalies, pulmonary artery and venous abnormalities, Tetralogy of Fallot, transposition of the great arteries, complex shunts, and single-ventricle/Fontan circulation. She also discussed pediatric challenges such as small anatomy, high heart rates, sedation needs, and the importance of specialized protocols, feed-and-swaddle techniques, and future tools like 4D flow, 3D printing, virtual reality, and AI. Clinical cases illustrated how CMR clarified difficult diagnoses and guided surgery.<br /><br />Dr. Amol Kulkarni then discussed adult CHD, especially repaired Tetralogy of Fallot, transposition of the great arteries, and coarctation of the aorta. He emphasized CMR for RV volumes, pulmonary regurgitation, baffle leaks, neo-aortic dilation, coronary anatomy, conduit stenosis, and residual or recurrent arch obstruction.<br /><br />A panel discussion explored practical limitations, including when CT may be preferable, how to interpret flow discrepancies, the role of LGE after contrast use, and the decreasing need for diagnostic cath in selected patients.<br /><br />Dr. Calvin Singh concluded with valvular heart disease, explaining how CMR assesses valve anatomy, stenosis/regurgitation severity, and myocardial remodeling/fibrosis, with examples in aortic and mitral disease.<br /><br />The session ended with a lively CMR quiz conducted by Dr. Vimal Raj, with prizes for top performers and a reminder to complete the course MCQ for certification.
