Giant Left and Right Atrium in Rheumatic Mitral Stenosis and Tricuspid Regurgitation.

Dilation of atria occurs in patients with valvular heart disease, especially in rheumatic mitral regurgitation, mitral stenosis, or tricuspid valve abnormalities. We report a case of giant left and right atrium in the context of rheumatic mitral stenosis and severe tricuspid regurgitation in a 68-year-old woman.
