2. Fig 1
Peak and mean aortic valve gradients before and after aortic valve replacement. The open bar in each set represents the preoperative gradient, while the shaded bar is the postoperative gradient across the prosthetic valve measured at least 1 year after surgery. Both mean and peak gradients were significantly reduced after surgery.

3. Fig 2
Left ventricular mass before (open bar) and 1 year after (shaded bar) aortic valve replacement surgery. Left ventricular mass was significantly reduced at the follow-up study.

4. Fig 3
Left ventricular septal and posterior wall thickness before (open bars) and after (shaded bars) surgery. Both posterior wall and septal thickness are significantly reduced after surgery.

5. Fig 4
Left ventricular end diastolic (LVEDD) and end systolic (LVESD) diameters before (open bars) and after (shaded bars) surgery. Both LVEDD and LVESD are significantly reduced after surgery.
