I am a bit confused. I have read that the Rheumatic fever is the most common cause of Mitral Stenosis but UW says Rheumatic Fever causes Mitral reguritation..
Mitral regurgitation is the most common early valvular manifestation and may be accompanied by aortic regurgitation; isolated aortic regurgitation is less common. Mitral regurgitation is often caused by mitral valve prolapse. Mitral valve prolapse in acute rheumatic fever involves predominantly the anterior leaflet with minimal leaflet redundancy, in contrast to myxomatous disease which more commonly involves the posterior leaflet and is associated with prominent leaflet redundancy. Leaflet prolapse appears to be due to annular dilation and chordal elongation. Aortic or mitral stenosis is unusual at presentation; these are typically late manifestations due to scarring and calcification of damaged valves.
Kaplan QBank also says the same - MR is a cardiac problem of RF.
