Serial cardiovascular MRI mid short-axis images in diastole (top row) and systole (bottom row) in a 76 WM taken the day prior to AVR, 6 months, one year and 4 years following AVR. The LV mass decreased from 186 to 154 g over the first 6 months to only regress to 132 g over the next 3 1/2 years demonstrating the early-rapid and late-slow pattern of LVH regression. Similarly, LVEF markedly improved after afterload relief from 54% to 60% in the first 6 months with no further improvements over the ensuing 3 1/2 years (62%).
