Assessment of Left-Ventricular Function

The Thoracic and Cardiovascular Surgeon, 1998
There are three distinct phases of the cardiac cycle (contraction, active relaxation, and passive relaxation) which should be examined in order to perform a thorough assessment of global left-ventricular function. Accurate measurements of left-ventricular pressure and volume are necessary to assess these phases of the cardiac cycle.

Left Ventricular Function

2012
Many of the substitute endpoints used in clinical research on heart disease are parameters obtained using imaging techniques. The most frequently used endpoint is left ventricular ejection fraction (LVEF). At rest and at peak aerobic exercise, left ventricular contractility measurements can be obtained in a clinical setting by noninvasive methods [1 ...

Left Ventricular Systolic Function

2016
The estimation of left ventricular systolic function, both qualitative and quantitative, remains essential to the perioperative management of the cardiovascular status of the surgical patient. As a result of its portability and versatility, echocardiography is now widely used for this purpose (Lang et al. in European Journal of Echocardiography 7(2):79–

Left ventricular diastolic function

2020
Abnormalities of diastolic function in the critically ill have been demonstrated to be associated with important intensive care outcomes such as mortality and ventilator weaning failure. The assessment of left ventricular (LV) diastolic function refers requires the analysis of the onset, pattern, and termination of left ventricular filling as ...

Left ventricular systolic function

2020
Left ventricular systolic function assessment is an essential component of the echocardiographic assessment of the critically ill patient. A wide range of diseases from sepsis to coronary ischaemia can affect the left ventricle (LV). An understanding of the events and timings in LV systole within the cardiac cycle is important, together with an ...

Left Ventricular Diastolic Function

Journal of Diagnostic Medical Sonography, 1993
Two-dimensional echocafdiography has gained widespread acceptance I as the procedure of choice to evaluate left ventricular function. In the last decade, the importance of diastolic function in the overall performance of the left ventricle has received much attention.

Left ventricular and left atrial function

2015
Global left ventricular (LV) function is an important prognostic parameter and is useful for therapeutic decision-making. Since its introduction, two-dimensional (2D) echocardiography has played an important role in the quantitation of LV function.

Understanding Left Ventricular Function

1988
The characteristics of cardiac muscle contraction and relaxation have been extensively investigated using isolated heart muscle preparations. In such preparations, the effects of changes in preload (Starling’s law of the heart) and in contractility have been clearly defined, and many indices of contractility described.

Left Ventricular Pump Function

1997
The heart is a cleverly designed organ that propells blood around the body. Satisfactory performance depends on competent cardiac valves and powerful contraction of cardiac muscle. The heart’s performance is often compared to that of a hydraulic pump where efficiency is computed as the ratio of work performed to oxygen consumed.
