Rheumatic Mitral Stenosis

Rheumatic mitral stenosis is mitral-valve narrowing from rheumatic leaflet thickening, commissural fusion, and chordal shortening, presenting years after acute rheumatic fever with dyspnea, atrial fibrillation, and pulmonary congestion. Treatment: diuretics/salt restriction; rate control/anticoagulation for AF; percutaneous balloon mitral valvotomy or surgical commissurotomy/replacement for significant symptomatic stenosis; secondary penicillin prophylaxis.

Common Symptoms

Dyspnea; atrial fibrillation; LA enlargement; diastolic murmur; history of rheumatic fever

Causes and Pathogenesis

Rheumatic inflammation thickens/fuses mitral leaflets, narrowing the orifice.

Treatment

Diuretics; rate control/anticoagulation; balloon valvotomy/surgery; secondary penicillin prophylaxis

Preventive Measures

Secondary prophylaxis; anticoagulate AF; treat symptoms early.
