Treat symptomatic severe pulmonary valve stenosis

Question 1

The palpable, late-peaking systolic murmur located at the second left intercostal space; absence of an ejection click; and features of right ventricular pressure overload suggest?

Answer 1

Severe pulmonary valve stenosis.

Question 2

The echocardiogram confirms the presence of severe pulmonary valve stenosis with?

Answer 2

Peak systolic gradient of 65 mm Hg and mean systolic gradient of 50 mm Hg

Question 3

Balloon valvuloplasty is recommended for?

Answer 3

symptomatic patients with appropriate valve morphology

who have a peak Doppler gradient of greater than 50 mm Hg

Hg or a mean gradient greater than 30 mm Hg

favorable valve characteristics for percutaneous intervention.

Question 4

Do patients with pulmonary valve stenosis without a history of endocarditis or pulmonary valve replacement require endocarditis prophylaxis

Answer 4

No

Question 5

Surgical pulmonary valve replacement should be considered when?

Answer 5

The valve is dysplastic

more than moderate coexisting pulmonary valve regurgitation

small annulus

severe subvalvar or supravalvar pulmonary valve stenosis

another cardiac lesion that requires operative intervention is present
