Pulmonalinsufficiens (regurgitation af pulmonalklappen)
| Let regurgitation | Moderat regurgitation | Svær regurgitation | |
| Pulmonalklappens morfologi | normal | normal/abnorm | abnorm |
| Signalintensitet ved CW-Doppler | svag, langsom deceleration | variabel | kraftig, stejl deceleration, tidligt ophør af det diastoliske flow |
| Jetbredde ved farve-Doppler | lille, < 10 mm i længden, smal oprindelse | variabel | stor, bred oprindelse |
| Forholdet mellem pulmonal- og aortaflow | normalt | variabelt | betydeligt forøget |
