Heart disease affects about 10 percent of dogs. Insufficiency of the mitral valve is the most common cause, accounting for 75-80 percent of heart disease cases. Mitral valve disease is more common in ...

The mitral valve controls the flow of blood from the heart’s left atrium down to the left ventricle, where it is pumped out to the body. When part of the valve doesn’t close properly, it’s called ...

Mitral valve prolapse is a common cause of a heart murmur caused by a "leaky" heart valve. Most cases of mitral valve prolapse are not serious and only need to be monitored. Mitral valve prolapse is ...

Diagnosis: Rheumatic valvular disease with severe mitral stenosis, moderate mitral regurgitation, moderate aortic regurgitation, moderate aortic stenosis, severe tricuspid regurgitation, and mild ...

ABOVE: An echocardiogram from the patient shows that the left side of the heart has severely thickened mitral valve leaflets (white arrow). LEFT: In this echocardiogram with color Doppler applied, the ...

What Is Mitral Valve Regurgitation? When your heart pumps blood, it’s supposed to follow a specific path in one direction. But sometimes, it goes the wrong way. Mitral valve regurgitation is when your ...

Disease of the cardiac valves and other cardiac structures frequently results in abnormal, turbulent blood flow within the heart, causing murmurs. Careful auscultation of heart murmurs is an extremely ...

Mitral-valve repair can be accomplished with an investigational procedure that involves the percutaneous implantation of a clip that grasps and approximates the edges of the mitral leaflets at the ...

Staphylococcus aureus endocarditis commonly causes severe valve damage such as chordal rupture, abscess, pseudoaneurysm formation, or perforation. In this patient a large defect is seen in the ...

Murmurs are described by their timing in the cardiac cycle, intensity, shape, pitch, location, radiation and response to dynamic maneuvers. Using the aforementioned criteria, a clinician can ...
