Which wall of hea is enlarged first in a patient with mitral stenosis
* Rheumatic fever is the leading cause of mitral stenosis (MS). Other less common etiologies of obstruction to left ventricular inflow include: * congenital mitral valve stenosis, * cor triatriatum, * mitral annular calcification with extension onto the leaflets, * systemic lupus erythematosus, * rheumatoid ahritis, * left atrial myxoma, and * infective endocarditis with large vegetations. * Pure or predominant MS occurs in ~40% of all patients with rheumatic hea disease and a history of rheumatic fever.
