Case Session 05: Systemic and Inflammatory Disease (2018)-How can CMR help to identify infectious diseases affecting the heart

How can CMR help to identify infectious diseases affecting the heart

Video Transcription

Video Summary

Cardiac MRI (CMR) is presented as a key noninvasive tool for diagnosing infectious heart diseases, especially myocarditis, but also pericarditis, endocarditis, pancarditis, and Chagas heart disease. It detects inflammation through T2 imaging/mapping for edema, early gadolinium enhancement for hyperemia, and late gadolinium enhancement for necrosis and fibrosis. The talk explains how CMR helps distinguish myocarditis from ischemic injury by showing noncoronary, often subepicardial or mid-wall lesions, and it can also assess prognosis, guide treatment, and sometimes avoid coronary angiography.
