Disorder - Mitral valve stenosis

Organ Systems Involved
Cardiovascular

Alternative disorders described within LIDA

Congenital supravalvular mitral stenosis; Congenital dysplasia of the mitral valve complex

Presenting Signs

With this heart valve disorder, cats may have weakness in the hindlimbs, a reduced appetite (anorexia) and/or a low temperature (hypothermia). The cat may be breathing faster, or have trouble breathing. There may be an increased heart rate. Listening to the heart (auscultation) with a stethoscope would reveal a heart murmur. An ultrasound would reveal abnormal heart valves, and possibly enlargement of the heart or fluid surrounding the lungs. There may also be abnormal lung sounds, coughing or problems in the pulse. Extremities may be cold or bluish in appearance. There may be some fluid in the lung or in the space inside the pleural membranes, surrounding the lungs.

Breeds Affected
Siamese


Treatment

Surgical and medical: medical therapy with diuretics, vasodilators, anti-clotting drug, and ace-inhibitors has been reported to help abate clinical signs. Surgery has been described as a potentially possible way to correct mitral valve stenosis.
