ClinConnect Summary

Surgery for severe aortic stenosis (AS) prior to symptom onset is controversial. Conventionally changes in valve area and gradient are used to time intervention but myocardial changes may be more predictive of surgical need. This study aims to elucidate the role of diffuse myocardial fibrosis as a prognostic marker, implementing a novel, non-invasive technique to measure it.

AS is the most common valvular heart condition in the United Kingdom and the Western world. Its prevalence rises with age - about 3% aged over 75 have severe AS. During a period of progressive valve narrowing, the left...
