Figure 1 The left ventricular mass index (LVMI)/left ventricular end-diastolic volume index (LVEDVI) of 12 patients with aortic valve stenosis and 7 patients with aortic regurgitation, before (PRE) and after (POST) valve replacement, compared with 10 control subjects. 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).
