Pulmonary valve regurgitation

Pulmonary valve regurgitation, if trivial to mild, is so common that it is considered physiologic.

Mild pulmonary regurgitation is extremely useful echocardiographically, as the Doppler velocity of the regurgitant trace may be used to predict mean and end-diastolic pulmonary artery pressures.

Pulmonary valve regurgitation is commonly noted in adults, and recognized originating from the pulmonic valve as turbulent flow traveling into the ventricular outflow tract during diastole.

There are several pathologic causes of pulmonary valve regurgitation, including its association with pulmonary valve stenosis.

Dilation of the pulmonary annulus, which can be idiopathic or due to pulmonary artery dilation, amplitude (less than 6 mm) with thickening of the leaflets.

Pulmonic valve regurgitation can be caused by numerous cardiac pathologies, including:
*Pulmonary hypertension
*Bacterial endocarditis
*Pulmonary valvotomy
*Congenital defects
*Carcinoid heart disease
*Trauma
