Remarks |
In most instances, pulmonic stenosis is a congenital rather
than an acquired lesion. Most PS cases are due to valvular rather than sub-
or supravalvular stenosis. PS is associated with Noonan and Williams
syndromes.
Percutaneous valvuloplasty is the treatment of choice for valvular PS;
intervention should be considered when the peak gradient is >50 mm Hg
in a symptomatic patient (exertional dyspnea, angina, presyncope or
syncope). |
