Chapter 2 - Report of the Manitoba Pediatric Cardiac Surgery Inquest

... The normal heart consists of four chambers: two upper atria (singular: atrium) and two lower ventricles. The atria are the collecting chambers of the heart, into which blood flows from the body and the lungs. The atria pump blood into the ventricles, although the force of the atrial pumping action i ...

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.
