• aged mutants exhibit extracellular matrix abnormalities such as an increase in cleaved versican in the cusp and annulus regions, increase in total proteoglycan content and decrease in type I and III collagens in the aortic valves
• aortic valves exhibit extracellular matrix structural abnormalities including proteoglycan accumulation in the annulus region and abnormal cartilage-like nodule formation in subareas of the annulus, specifically near the commissures and aortic-mitral continuity
• nodules are characterized by chondrocyte-like halo-cell morphology and are seen at all stages, indicating a developmental abnormality preceding the development of aortic valve disease
• proteoglycan accumulation is seen only in aged mutants
• MMP expression in the annulus indicates early maladaptive extracellular matrix (ECM) remodeling in aortic valve malformation without aortic valve disease and worsening pathologic ECM remodeling with aortic valve disease
• aortic valves show a progressive decrease in regional tissue tensile stiffness
