Right Ventricular Ejection Fraction (RVEF) is an essential diagnostic measure in cardiology, quantifying the percentage of blood ejected from the heart’s right ventricle with each heartbeat. It’s a vital indicator of right ventricular function, particularly in diagnosing and monitoring cardiac conditions like right heart failure, pulmonary hypertension, and congenital heart diseases. A normal RVEF ranges from 45% to 60%, indicating efficient pumping of the right ventricle. When the RVEF is lower than normal, it suggests impaired right ventricular function, which can lead to inadequate blood flow to the lungs and subsequent oxygenation issues in the body. Right Ventricular Ejection Fraction (RVEF) is typically measured using imaging techniques like echocardiography, cardiac MRI, or radionuclide ventriculography. Monitoring Right Ventricular Ejection Fraction is crucial for guiding treatment decisions and predicting outcomes in patients with cardiovascular diseases.
