flow from the right ventricle into the pulmonary arteries, which carry blood to your lungs to pick up oxygen. The mitral valve lets oxygen-rich blood from your lungs pass from the left atrium into the left ventricle. The aortic valve opens the way for the oxygen-rich blood to pass from the left ventricle into the aorta and out to your body.
Mitral Valve Disease in the Dog
In dogs with mitral valve disease, called MVI, for mitral valve insufficiency, the valve between the left atrium and the left ventricle wears out and becomes leaky. The murmur sound we hear with a stethoscope is created by turbulent blood flowing the wrong direction, back around the leaking valve, from the left ventricle to the left atrium.

Heart Valve Disease: Mitral and Tricuspid Valves
Secondary (functional) mitral regurgitation does not involve anything wrong with the valve itself, but is a disease of the left ventricle of the heart. When heart disease causes the left ventricle to enlarge, the papillary muscles that support the mitral valve s two leaflets are moved and the valve opening (annulus) is stretched.

Improved preservation of left ventricular function due to maintenance of the papillary muscle - mitral annular continuity - has been demonstrated. Thromboembolism is rare after mitral repair in patients in sinus rhythm.
Patient Information Mitral Valve Regurgitation (Insufficiency)
The mitral valve is the door that separates the top part of the heart, the atria, from the bottom part, the ventricle, on the left side. Valves are like doors that open and close to allow pressure in the heart to increase and decrease which creates flow going forward.

MITRAL VALVE DISEASE AND HEART FAILURE IN DOGS
atrium and left ventricle is called the mitral valve Because of the high pressure created when the left ventricle contracts, the mitral valve may begin to l eak or wear out in many dogs. This is known as mitral valve insufficiency (MVI) and is often associated with a heart murmur and left -sided congestive heart failure (LS -CHF).

Rx for Success - Mitral or Aortic Valve Surgery(043)
Mitral stenosis is a narrowing of the valve opening, most often due to rheumatic fever. Mitral insufficiency (aka regurgitation) is the failure of the valve to close properly, thus allowing blood to flow abnormally back into the left atrium. Mitral valve prolapse (MVP) is a condition in which floppy valve leaflets (i.e., cusps) fail to close

Anatomy and function of the mitral valve Normal mitral valve function depends on perfect function of the complex interaction between the mitral leaﬂets, the subvalvular apparatus (chordae tendineae and papillary muscles), the mitral annulus, and the left ventricle (LV). An imperfection in any one of these components can cause the valve to leak.3

Minimally Invasive Mitral Valve Surgery
Long-standing or chronic mitral valve disease or insufficiency causes backwards flow of blood into the left atrium (LA) and destructively increases pressure on the left ventricle and heart. Over time, the left atrium dilates as a response to the larger volume. This remodeling produces an increase in LA and LV pressures.

Over time, this dysfunction can lead to enlargement of the left ventricle, weakening of the myocardium and pulmonary hypertension.

The prospect of noninvasively studying the active relaxation period of the left ventricle is also very attractive.
Minimally Invasive Mitral Valve Surgery
Mitral valve insufficiency allows blood to flow backwards into the left atrium, forcing the heart to work harder to push blood out into the body. Pressure increases in the left atrium and the left ventricle. Over time, in chronic mitral valve insufficiency, the heart expands detrimentally as a response to the increased blood volume.

Red arrows show the path of the oxygen-rich blood through the left atrium, mitral valve, left ventricle and aortic valve to the aorta.

The mitral valve normally acts as a seal on the left side of the heart between the left atrium (the filling chamber) and the left ventricle (the pumping chamber), Figure 1. When the ventricle contracts, oxygenated blood is pumped around the body, and the mitral valve closes and prevents blood from going back into the left atrium.
