Overview
pulmonic stenosis is most commonly secondary to acute rheumatic fever. Generally, the initial valvulitis is associated with valvular regurgitation but over a period of 2 or more years, the commissures fuse and the valves thicken and calcify. The chordal supporting structure also calcifies and retracts. The result is the typical “fish mouth deformity”. 70% of the time; the mitral valve is involved in isolation, and 25% of the time; the aortic valve is involved as well. The tricuspid and pulmonic valves are involved less commonly. Patients develop symptoms when the mitral vavle area is 2 to 2.5 cm2.
Pathophysiology
Almost all cases of pulmonic stenosis are due to disease in the heart secondary to rheumatic fever and the consequent rheumatic heart disease (a condition that may develop after strep throat or scarlet fever). Around 90% of cases of rheumatic heart disease are associated with pulmonic stenosis. [1] [2]</ref>
