Description

There is a lack of knowledge regarding the presence of myocardial fibrosis in patients with chronic primary mitral regurgitation before onset of symptoms and left ventricular dysfunction. The relationship between myocardial fibrosis and imaging detection is important, as additional methods are need to optimise care and outcomes in relation to timing intervention. Awareness of the presence of fibrosis and knowledge of associated factors that may drive the fibrotic process.

The CME activity aims to narrow the knowledge gap in terms of histological evidence of myocardial fibrosis and the relationship to imaging markers.

To close the gap above:

1. Learners need to know about the presence of myocardial fibrosis in asymptomatic and symptomatic patients with severe chronic primary MR.
2. Learners need to know how to apply this knowledge when interpreting cardiovascular imaging and tissue characterisation in these patients.
3. Learners need to recognise changes in tissue characterisation and associated factors in imaging these patients.
