Mitral stenosis(MS)
Also known as: Mitral valve stenosis · Congenital mitral stenosis · Mitralklappenstenose · Mitralstenose · Congenital mitral valve stenosis
Overview
What it is
Mitral stenosis is a congenital heart defect where the mitral valve, which controls blood flow between the left upper and lower chambers of the heart, is abnormally narrowed. This narrowing restricts normal blood flow through the heart, causing blood to back up into the blood vessels of the lungs. Over time, this fluid buildup puts significant strain on the cardiovascular system.
How it presents
Owners typically notice signs of exercise intolerance, rapid breathing, coughing, or fainting spells, which often appear in puppies or young adults. A veterinarian will also frequently detect an abnormal heart sound, known as a murmur, during a routine physical exam.
Treatment
While the condition cannot be cured, it can be managed with lifelong heart medications or a specialized balloon catheter procedure to widen the valve. Treatment and ongoing cardiological monitoring typically cost between €1,500 and €7,000.
