According to the American Heart Association/American College of Cardiology (AHA/ACC) guidelines, in case of domed pulmonic valve with moderate or severe valvular stenosis and less than moderate pulmonic valve regurgitation, balloon valvotomy is recommended.

Severe stenosis: peak gradient ≥64 mmHg; Moderate stenosis: peak gradient between 36 and 64 mmHg.

Otherwise, surgical repair is recommended in case of symptomatic patients with moderate or severe valvular pulmonic stenosis who are ineligible for balloon valvotomy or who have failed it.

In these patients, surgical repair is required to excise thickened and obstructive valve leaflets and place a transannular patch.
