Characteristics of the Posterior Aortic Wall Motions in M-mode Echocardiogram of the Patients with Various Valvular Heart Diseases

ABSTRACT

To observe the characteristics of the posterior aortic wall motions of the patients with various valvular heart diseases the aortic root echocardiogram of the 60 patients with various valvular diseases were examined. 15 cases in each group of patients with mitral stenosis, mitral insufficiency, mitral stenoinsufficiency or aortic insufficiency. Thirty normal subjects were served as a control group. In each, the total amplitude of the aortic posterior wall motion(OV), the amplitude of the motion evented at atrial systole(AV), AV/OV ratio, atrial emptying index(AEI), left atrial and aortic root dimensions (LAD and AOD), and LAD/AOD were measured. The results were as follows ; 1) The AV was significantly increased in mitral stenosis(P<0.01) and decreased in mitral insufficiency(P<0.05) compared with control group. 2) The OV was increase in mitral insufficiency and aortic insufficiency(p<0.01, p<0.05), but decreased in mitral stenosis(p<0.05). 3) The AV/OV was increased in mitral stenosis(p<0.01) and decreased in mitral insufficiency and aortic insufficiency(p<0.01). 4) The AEI was decreased in all patient groups(p<0.01) and LAD was increase in all compared with control group(p<0.01). 5) The AOD was increased only in aortic insufficiency(p<0.01). 6) The LAD/AOD ratio was increased in all patient groups(p<0.01).
