فیبریلاسیون دهلیزی بعد از جراحی دریچه میترال در بیماران رماتولوژیک و غیر روماتولوژیک متفاوت است.

Atrial fibrillation (AF) is the most common arrhythmia after open heart surgery that can lead to early morbidity and mortality following operation. Mitral stenosis (MS) is a structural abnormality of the mitral valve apparatus that can result from previous rheumatic fever or non-rheumatic fever such as congenital mitral stenosis, malignant carcinoid disease etc. This study was designed to test the hypothesis that type of mitral stenosis can affect on post-mitral valve replacement incidence, duration and frequency of AF, and early complications in patients undergoing mitral valve replacement
We concluded that type of mitral stenosis affect on post-operative outcomes, especially incidence of atrial fibrillation and some complications after mitral valve replacement
