Figure 2 Changes in left ventricular ejection fraction (LVEF) after surgical correction of chronic severe aortic regurgitation (solid triangles = group A patients; open triangles = group B patients). Group A and B patients have similar preoperative values (Pre-op). The LVEF is higher in group A patients after the procedure (Post-op) (p < 0.001) and at five-year (p < 0.001) and 10-year follow-up (p < 0.001).
