ACC / AHA Guidelines - Indications for balloon valvotomy in Pulmonary Stenosis (DO NOT EDIT)
According to 2008 ACC/AHA guidelines[1], following are the indications for balloon valvotomy in pulmonary stenosis:
| Class I |
| "1.Balloon valvotomy is recommended in adolescent and young adult patients with pulmonic stenosis who have exertional dyspnea, angina, syncope, or presyncope and an RV–to–pulmonary artery peak-to-peak gradient greater than 30 mm Hg at catheterization.(Level of Evidence: C) " |
| "2.Balloon valvotomy is recommended in asymptomatic adolescent and young adult patients with pulmonic stenosis and RV–to–pulmonary artery peak-to-peak gradient greater than 40 mm Hg at catheterization.(Level of Evidence: C) " |
| Class I |
| "1.Balloon valvotomy is not recommended in asymptomatic adolescent and young adult patients with pulmonic stenosis and RV–to–pulmonary artery peak-to-peak gradient less than 30 mm Hg at catheterization.(Level of Evidence: C) " |
CLASS IIb
1. Balloon valvotomy may be reasonable in asymptomatic adolescent and young adult patients with pulmonic stenosis and an RV–to– pulmonary artery peak-to-peak gradient 30 to 39 mm Hg at catheterization. (Level of Evidence: C)
CLASS III
1. Balloon valvotomy is not recommended in asymptomatic adolescent and young adult patients with pulmonic stenosis and RV–to–pulmonary artery peak-to-peak gradient less than 30 mm Hg at catheterization. (Level of Evidence: C) }}
