How long can patients with mitral stenosis live?

The most common form of mitral stenosis in adults is rheumatic fever, a condition known as rheumatic heart disease involving heart valves. Life expectancy depends on the age of onset. If a patient exhibits severe mitral stenosis in his 20s and does not undergo active valve replacement, his life expectancy may be around 50 years old, that is, he can live for more than 30 years. However, if the patient is in his 60s and exhibits mitral stenosis, it is possible that he will live to 70 or even 80. However, if the patient with mitral stenosis wants to prolong his life, he should undergo aggressive surgical valve replacement before presenting severe stenosis. Otherwise, as he gets older, he may lose the opportunity of surgery or the surgical results will become very poor.
