## What is Rvef?

Right ventricular ejection fraction (RVEF) is the measurement of how much blood is being pumped out of the right side of the heart to the lungs for oxygen. In most cases, the term “ejection fraction” refers to left ventricular ejection fraction.

## How is Rvef measured?

In CMR, right ventricular ejection fraction (RVEF) is often used as a measure of RV function. RVEF can be determined by calculating the end-diastolic and end-systolic volumes of the RV in the short-axis (SA) plane [5].

What is normal Rvef?

A normal LVEF reading for adults over 20 years of age is 53 to 73 percent. An LVEF of below 53 percent for women and 52 percent for men is considered low. An RVEF of less than 45 percent is considered a potential indicator of heart issues.

### What is Rvef heart?

CMR = cardiac magnetic resonance, RVEF = right ventricular ejection fraction, TAPSE = tricuspid annular plane systolic excursion, TTE = transthoracic echocardiography.

### What is the normal EF of the heart?

A normal ejection fraction is about 50% to 75%, according to the American Heart Association. A borderline ejection fraction can range between 41% and 50%.

How is EF calculated?

The ejection fraction or EF is an indicator of how efficient the ventricle is at emptying itself. It’s the percentage of the EDV that is ejected from the ventricle. The formula is: EF=SV/EDV. (If we want to turn this into a percentage, we simply multiply by 100).

## Can EF be improved?

Keeping tabs on it not only helps your doctor treat you more effectively but also leads to better outcomes. Cardiologist J. Emanuel Finet, MD, says it straight: “Low ejection fraction is directly proportional to survival. By improving it, you improve your survival outlook.”
