Global diastolic strain rate for the assessment of left ventricular relaxation and filling pressures.
BACKGROUND Diastolic strain rate (SR) measurements that comprise all left ventricular (LV) segments are advantageous over myocardial velocity for assessment of diastolic function. Mitral early diastolic velocity (E)/SR ratio during the isovolumetric relaxation (IVR) period can be used to estimate LV filling pressures. METHODS AND RESULTS Simultaneous echocardiographic imaging and LV pressure ...
متن کاملEarly diastolic filling dynamics in diastolic dysfunction
BACKGROUND The aim of the study was to determine the relationship between the rate of peak early mitral inflow velocity and the peak early diastolic mitral annular tissue velocities in normal controls and to compare them with subjects with diastolic dysfunction. METHODS The relationship between early passive diastolic transmitral flow and peak early mitral annular velocity in the normal and i...
متن کاملStress Cardiomyopathy (Takotsubo Cardiomyopathy)
BACKGROUND Due to the rise in the number of reports of stress cardiomyopathy in the literature, awareness of this condition is increasing. Although different names have been used to describe this condition, the similarities in clinical, electrocardiographic, echocardiographic, and angiographic features suggest that they represent the same spectrum of diseases with different underlying causes. T...
متن کاملEffect of dobutamine stress on left ventricular filling in ischemic dilated cardiomyopathy: pathophysiology and prognostic implications.
OBJECTIVES The purpose of this research was to study the effect of dobutamine on left ventricular (LV) filling in ischemic cardiomyopathy (ICM) and to determine whether restrictive filling pattern (RFP) at peak stress has prognostic value. BACKGROUND The prognostic value of RFP at peak stress in ICM is unknown. METHODS A total of 69 patients with ICM were studied by Doppler echocardiography...
متن کاملEstimation of left ventricular filling pressures by speckle tracking echocardiography in patients with idiopathic dilated cardiomyopathy.
AIMS the ratio of early diastolic transmitral flow velocity (E) to early diastolic mitral annular velocity (E(a)) is frequently used to predict an increase in left ventricular filling pressure (LVFP). However, this approach has several limitations. The aim of this study was to test whether additional information is gained by new echocardiographic indexes utilizing strain and strain rate (SR) de...
