Pulmonary valve stenosis

Fig 22

Pulmonary valve stenosis

RVOT

MPA

Continuous wave Doppler trace demonstrating

very high systolic velocity and the small ‘a’

wave during atrial systole. The later is the sign

for restrictive right ventricular physiology.

Parasternal short axis view of a thickened

and stenotic pulmonary valve (arrow). Note

that poststenotic dilatation of main pulmonary

artery, and significant right ventricular

hypertrophy


Pulmonary regurgitation

Pulmonary Regurgitation

A

B

Continuous wave Doppler recording obtained from the parasternal position directed through pulmonary

valve.

A: From a patient with mild PR, note the regurgitation signal persist till the end of diastole.

B: Patient with severe pulmonary regurgitation; the regurgitation signal ends at the middle of diastole.
