A 20-year-old woman has mild pulmonary stenosis. Which of the following statements regarding this situation is true?
Adults with mild pulmonic stenosis are generally asymptomatic. Unlike congenital aortic stenosis, this condition usually does not progress; thus, follow-up need not be frequent. The risk of endocarditis is somewhat lower for pulmonic valves than for the other heart valves, whether normal or stenotic. Clinical signs of mild pulmonic stenosis include a prominent a wave on jugular venous pulse, a normal electrocardiogram, and normal cardiac size on chest x-ray.
Heart size on chest x-ray is likely to be enlarged
Electrocardiogram is likely to be abnormal
There is loss of the jugular a wave
Compared to other valvular defects, the risk of endocarditis is relatively low
