Overview
Physical Examination
Neck
- Increased JVP
- Prominent "a wave" may be present
- Prominent "v wave" may be present in presence of tricuspid regurgitation
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.
