ABSTRACT
BACKGROUND AND OBJECTIVES:
Atrioventricular plane displacement (AVPD) has been used for evaluating systolic function. However, its relations with other echocardiographic variables reflecting diastolic function are not well documented. This study was designed to assess the relations between AVPD and those echocardiographic variables known to reflect diastolic function, especially using mitral annulus velocity. SUBJECTS ANDMETHODS:
Eighty-seven patients with normal left ventricular (LV) systolic function (normal echocardiography group (Group I, n=44), concentric left ventricular hypertrophy (LVH) group (Group II, n=43)) and 51 patients with LV dysfunction (Group III) were studied. To evaluate the correlation with echocardiographic variables reflecting LV systolic and diastolic function, we measured mitral inflow velocity and mitral annulus Doppler tissue velocity.RESULTS:
AVPD was correlated negatively with age, the ratio of early diastolic mitral inflow velocity and early diastolic mitral annulus velocity (E/E'), isovolumic relaxation time, and E/A ratio. AVPD was correlated positively with deceleration time, ejection fraction, and systolic mitral annulus velocity (S'). By multivariate analysis, AVPD was independently correlated with S' (beta=0.4, p<0.001) and E' (beta=0.5, p<0.001) in the normal LV function group, and with S' (beta=0.6, p<0.001) and E/E'(beta=-0.3, p=0.005) in the LV dysfunction group.CONCLUSION:
AVPD may be used as a diagnostic tool for evaluating LV diastolic function.
