Figure 2 (A) The maximum acceleration slope of early diastolic filling corrected for cardiac output (E accel peak/CO), and (B) the maximum deceleration slope of early diastolic filling corrected for cardiac output (E decel peak/CO) of 12 patients with aortic valve stenosis and 7 patients with aortic regurgitation, before (PRE) valve replacement and 9 ± 3 months after (POST) valve replacement, compared with 10 control subjects. The mean values are displayed with standard deviation bars. *p < 0.05 versus control subjects; p < 0.05 before surgery versus after surgery (paired two-tailed t test); p < 0.05 aortic stenosis versus aortic regurgitation (pre vs. pre or post vs. post).
