Cardiovascular magnetic resonance radiomics for phenotyping myocardial fibrosis in severe aortic stenosis
Myocardial fibrosis (MF) is a key determinant of adverse outcomes in severe aortic stenosis and limits the efficacy of valve implantation. Endomyocardial biopsy is the reference standard for diagnosing MF, but its invasiveness limits routine use. Cardiovascular magnetic resonance (CMR)-derived extracellular volum...
