High afterload rather than myocardial fibrosis predicts reduced ejection fraction in severe aortic stenosis with afterload mismatch
Background Afterload mismatch (AM) refers to high-gradient (mean gradient ≥40 mm Hg) severe aortic stenosis (AS) with reduced left ventricular ejection fraction (LVEF <50%) that is hypothesised to arise from mechanisms other than true contractile impairment. The extent, pattern and functional...
