Recently, an easily measured Doppler index of combined systolic and diastolic ventricular
myocardial performance (the Tei index) was proposed as a potentially useful predictor of …

BACKGROUND: The presence of signs and symptoms of heart failure (HF), abnormal
diastolic function and an ejection fraction> 45%, have been defined as diastolic HF (DHF) …

Tissue Doppler imaging (TDI) is a useful echocardiographic technique to evaluate global
and regional myocardial systolic as well as diastolic function. It can also be used to quantify …

The importance of systolic ventricular dysfunction in the genesis of the signs and symptoms
of congestive heart failure has long been recognized. It has only been in the last decade that …

Tissue Doppler imaging (TDI) has evolved to become a useful noninvasive method that can
complement other echocardiographic techniques in the assessment of left ventricular …

Doppler echocardiography is a noninvasive technique that provides unique hemodynamic
information otherwise not available without invasive monitoring. The accuracy of the results …

Tissue Doppler echocardiography is a variation of conventional Doppler flow imaging. This
modality allows quantification of the Doppler shift within the range of myocardial tissue …

Diastolic function represents the filling property of the heart during diastole. Diastole
comprises four phases: isovolumic relaxation, rapid filling, slow filling (diastasis), and active …

D iastolic dysfunction of the left ventricle is an important cause of cardiac morbidity and
appears to be one of the earliest detectable abnormalities in a number of disorders. 1-6 Left …

There are many myocardial and non-myocardial conditions that cause heart failure with
normal left ventricular ejection fraction (LVEF). Among them, diastolic heart failure (heart …
