Case Review Session 3: Valvular Heart Disease and Flow (2020)-Assessment of Mitral Valve Disease in Clinical Practice

Assessment of Mitral Valve Disease in Clinical Practice

Video Transcription

Video Summary

The speaker reviewed cardiac MRI assessment of mitral valve disease. He explained how MRI helps distinguish primary MR, caused by valve abnormalities like prolapse or flail, from secondary MR due to ventricular or atrial dilation. He showed how to evaluate mitral annular disjunction, calcification, stenosis, repairs, replacements, and procedure complications. Key MRI methods include measuring regurgitant volume/fraction from ventricular and aortic stroke volumes, or directly planimetering the regurgitant orifice. MRI also accurately measures ventricular function and can detect delayed enhancement/fibrosis, which may have prognostic value.
