What is tricuspid stenosis?

• Tricuspid stenosis (TS), which is much less prevalent than mitral stenosis (MS) in North America and Western Europe (generally rheumatic in origin, and is more common in women than men) • A mean diastolic pressure gradient of 4 mmHg is usually sufficient to elevate the mean RA pressure to levels that result in systemic venous congestion. • TS is almost always accompanied by significant TR. (Operative repair may permit substantial improvement of tricuspid valve function. If repair cannot be accomplished, the tricuspid valve may have to be replaced )
