Outreach Session: Outcomes Research and Imaging (2018)-Is it Time to Include CMR as a Core Attribute in Classification of Cardiomyopathies?

Is it Time to Include CMR as a Core Attribute in Classification of Cardiomyopathies?

Video Transcription

Video Summary

The speaker argues that CMR should become a core part of cardiomyopathy classification. He explains that cardiomyopathies are often genetic and involve families, not just individual patients, and that phenotype alone is not enough for prognosis or treatment decisions. He proposes the MOJES system: Morpho-functional phenotype, Organ involvement, Genetic transmission, Etiology, and Staging, modeled on TNM cancer staging. This framework can describe disease more precisely, including early or mixed forms. He also highlights why imaging must be added: ejection fraction alone is often misleading for ICD decisions, while CMR findings like late gadolinium enhancement and native T1 mapping better predict scar, fibrosis, arrhythmia risk, and mortality. The talk concludes that adding CMR to classification will improve communication, research registries, and clinical management of cardiomyopathies.
