Mitral regurgitation, also known as mitral insufficiency or mitral incompetence, is the backward flow of blood from the left ventricle, through the mitral valve, and into the left atrium, when the left ventricle contracts, resulting in a systolic murmur radiating to the left armpit.
Mitral regurgitation: the backflow of blood from the left ventricle into the left atrium, owing to insufficiency of the mitral valve; it may be acute or chronic, and is usually due to mitral valve prolapse, rheumatic heart disease, or a complication of cardiac dilatation. See also Mitral regurgitation.
Symptoms tend to present between 40 and 70 years of age. Mitral regurgitation is a holosystolic murmur. One can best hear it at the apex location and it may radiate to the axilla or precordium. When associated with mitral valve prolapse, one may hear a systolic click. In this scenario, valsalva maneuver will decrease left ventricular preload.
Mitral regurgitation. Mitral regurgitation (MR) occurs when the mitral valve fails to close completely, causing blood to flow back into the left atrium during ventricular systole. The constant backflow of blood through the leaky mitral valve implies that there is no true phase of isovolumic contraction.
This can also produce a mid-diastolic murmur, such as in severe mitral regurgitation where a large regurgitant volume in the left atrium can lead to "functional mitral stenosis." Mid-diastolic Austin Flint murmur: An apical diastolic rumbling murmur in patients with pure aortic regurgitation.
During diastole, the mitral valve opens and lets blood fill into the ventricle. If the mitral valve doesn’t open enough, it gets harder to fill the left ventricle, called mitral valve stenosis. Let’s start with mitral valve regurgitation - the leading cause of mitral valve regurgitation in the United States and the most common of all ...
Mitral valve prolapse is frequently associated with mild mitral regurgitation, [15] where blood aberrantly flows from the left ventricle into the left atrium during systole. In the United States, MVP is the most common cause of severe, non-ischemic mitral regurgitation. [4]
This disease is classified using regurgitant fraction (RF), or the amount of volume that flows back through the valve divided by the total forward flow through the valve during systole. Severe disease has an RF of >50%, while progressive aortic regurgitation has an RF of 30–49%.
