Estimation of left ventricular fillings pressures by speckle tracking echocardiography in patients with idiopathic dilated cardiomyopathy
Result description
The ratio of early diastolic transmitral flow velocity (E) to early diastolic mitral annular velocity (Ea) is used to predict an increase in left ventricular filling pressure (LVFP). We tested whether additional information is gained by new echocardiographic indexes utilizing strain and strain rate (SR) derived from 2D speckel tracking echocardiography (2D-STE) for the estimation of LVFP. Fifty-one patients with idiopathic dilated cardiomyopathy underwent pulsed-wave tissue Doppler echocardiography and2D-STE performed simultaneously with right heart catheterization. ROC analysis showed that circumferential strain and the SR during late diastolic LV filling, E/circumferential SR at early diastolic LV filling, and E/circumferential strain at the time ofpeak E-wave had greater area under the curve than the E/Ea ratio for the prediction of pulmonary capillary wedge pressure >12mmHg. Compared to the E/Ea ratio, several 2D-STE-derived parameters better estimated the increase in LVFP in pat
