Overview
Echocardiography
2D Echocardiography
- Thickened leaflets with systolic bowing in valvular stenosis.
- Difficult to distinguish between valvular, sub valvular and supra valvular stenosis with 2D echocardiography.
- Post stenotic pulmonary artery dilatation can be visualised sometimes.
Doppler Echocardiography
- Ante grade velocity increased with corresponding maximum and mean pressure gradients.
- Pulmonary valve area can be calculated using the continuity equation.
- Pulmonary Valve Area = (Cross sectional areaRVOT * VTIRVOT)/ VTIPV
- The site of obstruction can be difficult to diagnose by 2D echo. Cautious use of colour flow mapping and PW Doppler can pin point the location of obstruction.
- Pulmonic Stenosis 1

Severity Assessment
| Severity | mild | moderate | severe |
|---|---|---|---|
| Valve area | >1.0 | 1- 0.5 | <0.5 |
| Peak gradient (mm Hg) | <10-25 | 25-40 | >40 |
2008 ACC/AHA Guidelines for the Management of Adults With Congenital Heart Disease (DO NOT EDIT)[1]
Recommendations for Evaluation of the Unoperated Patient (DO NOT EDIT)[1]
| Class I |
| "1. Two-dimensional echocardiography-Doppler, chest x-ray, and ECG are recommended for the initial evaluation of patients with valvular PS.(Level of Evidence: C) " |
| "2. A follow-up physical examination, echocardiography-Doppler, and ECG are recommended at 5-year intervals in the asymptomatic patient with a peak instantaneous valvular gradient by Doppler less than 30 mm Hg.(Level of Evidence: C) " |
| "3. A follow-up echocardiography-Doppler is recommended every 2 to 5 years in the asymptomatic patient with a peak instantaneous valvular gradient by Doppler greater than 30 mm Hg.(Level of Evidence: C) " |
| Class III |
| "1. Cardiac catheterization is unnecessary for diagnosis of valvular PS and should be used only when percutaneous catheter intervention is contemplated. (Level of Evidence: C) |
2008 ACC/AHA Guidelines for the Management of Patients with Valvular Heart Disease (DO NOT EDIT)[2]
Evaluation of Pulmonic Stenosis in Adolescents and Young Adults (DO NOT EDIT)[2]
| Class I |
| "1. Transthoracic Doppler echocardiography is recommended for the initial evaluation of pulmonic stenosis in adolescent and young adult patients, and serially every 5 to 10 years for follow-up examinations. (Level C)" |
