Pulmonic Valve Regurgitation

  • Pulmonic Valve Regurgitation is usually due to a functional defect in pulmonic valve closure due to dilation of the pulmonic annulus secondary to dilative right ventricular hypertrophy. In general, any pathophysiological process that leads to severe pulmonary hypertension will result in right ventricular hypertrophy which in its end-stage takes a eccentric pattern, enlarging the pulmonic annulus, and thus potentially leading to pulmonic regurgitation. Pulmonic regurgitation can be ausultated as a decrescendo, blowing diastolic heart murmur along the left sternal border.
