WebEjection fraction (EF) is a measure of how much blood leaves the heart with each heartbeat. Every heartbeat cycle has two parts: Contraction and relaxation. When the heart contracts, blood is ejected from two ventricles. During relaxation, the ventricles are filled with blood. No matter how forceful heart contractions get, they’re never ... WebIntroduction Cardiovascular MRI (CMR) is the gold standard for calculation of left ventricular ejection fraction (LVEF). Echocardiography (echo) has been shown to consistently underestimate LVEF when compared to CMR. However, this has not been demonstrated for different categories of LVEF.
