Because of diastolic coupling between the left atrium and left ventricle, we hypothesized that left atrial (LA) function mirrors the diastolic function of left ventricle. The aims of this study were to assess whether LA volume parameters can be good indexes of left ventricular diastolic dysfunction. Six hundred fifty-nine patients underwent cardiac catheterization and measurements of left ventricular filling pressure (LVFP). Echocardiographic examinations including tissue Doppler and LA volumes were also assessed. Ratio of early diastolic mitral inflow velocity to early diastolic mitral annular velocity and LVFP tended to increase after progression of diastolic dysfunction. The inverse phenomenon existed in LA ejection and LA distensibility. LA distensibility was superior to LA ejection fraction and early diastolic mitral inflow velocity/early diastolic mitral annular velocity for identifying LVFP >15 mm Hg (areas under receiver operating characteristic curve 0.868, 0.834, and 0.759, respectively) and for differentiating pseudonormal from normal diastolic filling (areas under receiver operating characteristic curve 0.962, 0.907, and 0.741, respectively). Multivariate logistic regression showed that LA ejection fraction and LA distensibility were associated significantly with the presence of pseudonormal/restrictive ventricular filling. In conclusion, LA volume parameters can identify LVFP >15 mm Hg and differentiate among patterns of ventricular diastolic dysfunction. For assessing diastolic function LA parameters offer better performance than even tissue Doppler.
