Overview

Physical examination findings of pulmonary regurgitation includes increased JVP, prominent "a" wave, "v" wave in the neck. A palpable impulse (lift or heave) is usually present at the left lower sternal border because of right ventricular dilation. On auscultation, it may be associated with wide splitting of S2 with right sided S3 accentuated with respiration. Murmer of pulmonic regurgitation may vary depending on the underlying cause.[1]

Physical Examination

Neck

Palpation

  • A palpable impulse (lift or heave) is usually present at the left lower sternal border because of right ventricular dilation.

Auscultation

Heart Sounds

  • Pulmonic regurgitation is associated with wide splitting of S2.
  • P2 is accentuated because of presence of pulmonary regurgitation. In case of, absence of pulmonic valves (congenital or secondary to surgical resection), P2 is inaudible.
  • A right-sided S3 may be audible and may also be accentuated with inspiration.
  • Likewise, a right-sided S4 may also be audible and accentuated with inspiration.

Murmur

  • Murmur of residual pulmonic regurgitation after Tetralogy of Fallot repair:[1]
    • It is a low-pitched and soft murmur.
    • Best heard along the second or third intercostal spaces adjacent to the left sternal border.
    • It is accentuated by squatting and inspiration.
    • It is made softer by Valsalva maneuvers or expiration.
  • Murmur of pulmonic regurgitation associated with Pulmonic hypertension:[2]
    • When the pulmonary artery systolic pressure exceeds 60 mm Hg, dilatation of the pulmonary artery ring may then result in Graham-Steell's murmur.
    • It is a high-pitched, "blowing", early diastolic decrescendo murmur like that of aortic regurgitation.
    • Best heard along the left parasternal region.
    • It is accentuated by inspiration.
