| Findings suspicious for prosthetic pulmonary valve stenosis |
|---|
| Cusp or leaflet thickening or immobility Narrowing of forward color map Peak velocity through the prosthesis >3 m/s or >2 m/s through a homograft* Increase in peak velocity on serial studies** Impaired RV function or elevated RV systolic pressure |
*Suspicious but not diagnostic of stenosis.
**More reliable parameter.
