2. Fig 1
Peak pressure gradients according to type of repair, preoperatively, immediately after surgery and at last follow-up. Gradients are expressed as means with one standard deviation. Mean follow-up was 7.0 ± 6.5 years following one-patch repair (▴-▴), 8.9 ± 4.3 years after Doty procedure (●-●), and 5.0 ± 3.3 years after Brom repair (■-■).
