ABSTRACT
Objective To evaluate of left atrial(LA) function in patients with rheumatic mitral stenosis(MS) by real time three‐dimensional echocardiography (RT‐3DE) .Methods Thirty patients with MS and 50 healthy volunteers underwent RT‐3DE . The left atrial end‐diastolic volume (LAVmax ) ,end‐systolic volume (LAVmin ) and pre‐systolic volume (LAVpre ) were measured to calculate the total ,passive and active atrial stroke volume (TASV ,PASV ,AASV) ,left atrial expansion index (LAEI) ,left atrial to‐tal ,passive ,active ejection fraction (LAEF ,LAEFpassive ,LAEFactive ) .The volume data were corrected by body surface area (BSA) to gettheleftatrialend‐diastolicvolumeindex (LAVmaxI),end‐systolicvolumeindex(LAVminI),pre‐systolicvolumeindex(LAVpreI) and the total ,passive and active atrial stroke volume index (TASVI ,PASVI ,AASVI) .The correlations between the LA volume , stroke volume ,function indices and the mitral valve area (MVA) were analyzed .Results (1)LAVmaxI ,LAVminI and LAVpreI were significantly greater in patients with MS than the controls(all P0 .05) .(3) LAEI ,LAEF ,LAEFpassive and LAEFactive were significantly lower in patients with MS than the controls(all P0 .05) .Conclusion LA function in patients with mitral stenosis decreased .RT‐3DE can be used to evaluate LA function in patients with MS and sinus rhythm .
