In the United States, pulmonic stenosis often results from calcium deposits on the pulmonic valve. These deposits occur naturally with age and have no relationship with the amount of calcium in the diet. Worldwide, aortic stenosis occurs most commonly in those who've had rheumatic fever, a condition that may develop after strep throat or scarlet fever. Valve problems do not develop for 5 - 10 years or longer after rheumatic fever occurs. Rheumatic fever is increasingly rare in the United States. pulmonic stenosis may be present from birth (congenital), or it may develop later in life (acquired). Children with pulmonic stenosis may have other congenital conditions. Radiation treatment to the chest, and some medications may cause pulmonic stenosis. pulmonic stenosis is not common. It occurs more often in men than in women. As the pulmonic valve becomes more narrow, the pressure increases inside the lower chamber of the heart (the right ventricle). This causes the right ventricle to become thicker, decreasing blood flow and can lead to chest pain.
