... In the 1980s, clinicians reported what seemed to be a surprisingly high prevalence (approximately 30%) of a normal LV ejection fraction in patients with congestive heart failure (14–16). Recurrent pulmonary edema was reported in elderly patients with ischemic heart disease—despite a normal LV ejecti ...

Mitral insufficiency
Mitral insufficiency (MI), mitral regurgitation or mitral incompetence is a disorder of the heart in which the mitral valve does not close properly when the heart pumps out blood. It is the abnormal leaking of blood backwards from the left ventricle, through the mitral valve, into the left atrium, when the left ventricle contracts, i.e. there is regurgitation of blood back into the left atrium. MI is the most common form of valvular heart disease.
