FIBER ORIENTATION AND EJECTION FRACTION IN THE HUMAN LEFT VENTRICLE EDWARD A. SALLIN From the Department ofBionmathematics, University ofAlabama Medical Center, Birmingham, Alabama35233 ABSTRACT Fiber orientation and ventricular geometry are incorporated in a mathematical model for ejection fraction ofthe human left ventricle.

Ejection fraction is the fraction of the end-diastolic volume (EDV, i.e blood volume in the ventricle at the end of diastole) that is pumped out during systole. Currently, two-dimensional (2D) echocardiography for calculation of ejection fraction is the dominant method for assessing left …

A. Ejection fraction refers to the volume of blood that's pumped out of the heart's left ventricle each time it contracts. Contrary to what many people believe, a normal ejection fraction is not 100%. Even a healthy heart pumps out only about half to two-thirds of the volume of blood in the chamber in one heartbeat. In most cases, ejection fraction refers to the percentage of blood that's pumped out of the left ventricle with each heartbeat. For example, an ejection fraction of 50% means that 50% of the blood from the left ventricle is being pumped out during each beat. There are two types of ejection fraction: left ventricular and right ventricular.

Therefore, it can be stated that the normal range for the left ventricle (LV) ejection fraction is 55 to 70 percent. What Does the Ejection Fraction Tell Us The left ventricular ejection fraction (LEVF) might seem like an arbitrary measurement, but it can tell us a lot about the health of a person’s heart. 2009-01-21 · Normal ranges for left ventricular mass, volumes and function. All variables varied according to age group (ANOVA, p < 0.05) except for EDV/BSA (p = 0.13) and ESV/BSA (p = 0.06) in males, and EDV (p = 0.39), EDV/BSA (p = 0.15), ESV/BSA (p = 0.28), SV (p = 0.14) and LVM/BSA (p = 0.24) in females.

The left ventricle squeezes and pumps some (but not all) of the blood in the ventricle out to your body. A normal ejection fraction is more than 55%.

2019-12-09 · Ejection fraction from 55% to 70%. When the pumping ability of the heart is normal, between 55% and 70% of the blood is pushed out into the body by the left ventricle each time the heart contracts. Just because heart function appears normal based on the ejection fraction, it is still possible to have heart failure.

Anatomy and Views. The most common views to assess for left ventricular ejection fraction are the parasternal long axis, parasternal short axis (mid-papillary level), and apical 4 chamber view.The subxiphoid view can also be performed with the parasternal or apical views cannot be obtained.

A left ventricle ejection fraction below 53% for women and 52% for men is considered low. An ejection fraction of 45% or below is considered a potential indicator of heart issues. Ejection fraction can also be too high. An ejection fraction of 75% or higher may indicate a heart condition such as hypertrophic cardiomyopathy. Ejection fraction (EF), is shown in the following equation: EF is normally 65% to 80% and does not change appreciably with age.

Left ventricular Ejection Fraction of lower than 52% in men and lower than 54% in women are considered abnormal left ventricular systolic function. Normal range cut-off values for 2D LVF EF in % according to current ASA Guidelines Heart failure with preserved ejection fraction (HFpEF) is a form of heart failure in which the ejection fraction - the percentage of the volume of blood ejected from the left ventricle with each heartbeat divided by the volume of blood when the left ventricle is maximally filled - is normal, defined as greater than 50%; this may be measured by echocardiography or cardiac catheterization.

That’s because there’s less blood coming into the stiffened left ventricle, but your heart is still able to pump that blood It means that the left ventricle is very efficient and is pumping 70% of the total blood volume it contains OUT into the bloodstream.

It means that the left ventricle is very efficient and is pumping 70% of the total blood volume it contains OUT into the bloodstream. When the ejection fraction drops into the 50% range, it means the heart has been damaged by disease or a heart attack.
