Figure 1: Myocardial Fibrosis in Subtypes of Aortic Stenosis

(A) No/mild myocardial fibrosis in a patient with “classical” aortic stenosis. (B) Severe myocardial fibrosis in a patient with “paradoxical” aortic stenosis. (C) Distribution of different degrees of myocardial fibrosis. Mann-Whitney U test revealed significant differences between control group and all AS patients (p = 0.001). Comparison was made between study patients’ subgroups using Kruskal-Wallis test (p = 0.007). ASrEF = aortic stenosis with reduced left ventricular ejection fraction; cAS = “classical” aortic stenosis; pAS = “paradoxical” aortic stenosis.
