Normal long axis function

The importance of long axis ventricular function.

Maternal left ventricular diastolic and systolic long-axis function during normal pregnancy.

AIMS The aim of this study was to evaluate left ventricular (LV) function during normal pregnancy and investigate the effect of maternal factors. Little information about LV diastolic and long-axis systolic function in normal pregnancy exists. METHODS AND RESULTS Two hundred and twenty eight Doppler echocardiography and DTI studies of the mitral annulus were performed in 63 normal pregnant wo...

Assessment of regional long-axis function during dobutamine echocardiography.

Echocardiographic analysis of regional left ventricular function is based upon the assessment of radial motion. Long-axis motion is an important contributor to overall function, but has been difficult to evaluate clinically until the recent development of tissue Doppler techniques. We sought to compare the standard visual assessment of radial motion with quantitative tissue Doppler measurement ...

Systolic left ventricular long axis function during dobutamine stress echocardiography.

AIMS To compare long-axis function and wall motion analysis for the detection of significant coronary artery stenoses in patients with single and multivessel disease. METHODS AND RESULTS We performed dobutamine stress echocardiography in 67 subjects, 14 with normal coronary anatomy, and 53 with significant coronary disease. A blunted increase in mean long-axis shortening of <0.25 cm was the b...

Comparability of M mode echocardiographic long axis and short axis left ventricular function derivatives.

M mode echocardiographic anteroposterior indexes of left ventricular function derived from long and short axis parasternal planes were compared in one hundred cases. In all the disease groups studied the paired values were within acceptable statistical limits of comparability and interchangeability; that is they were within two standard deviations of the mean difference in both directions. Valu...
