Comparative StudyDeterminants of preserved diastolic function at the lateral annulus in patients with isolated diastolic dysfunction.
The reversal of the early diastolic mitral annular velocity (e') to the late diastolic mitral annular velocity (a') ratio (e'/a' <1) develops earlier in the septum than in the lateral mitral annulus on tissue Doppler imaging (TDI). Accordingly, patients with isolated diastolic dysfunction presenting as a reversed septal e'/a' ratio can be divided into two groups depending on the presence of a reversal of lateral e'/a'. The aim of this study was to identify the determinants of preserved diastolic function at the lateral annulus in patients with isolated diastolic dysfunction. ⋯ The age, septal TDI, and LVM/h(2.7) were independent determinants of preserved diastolic function at the lateral annulus in patients with isolated diastolic dysfunction presenting as a reversed septal e'/a' ratio.
