Pulmonary Regurgitation

Pulmonary regurgitation commonly occurs with pulmonary artery dilatation due to pulmonary hypertension. It rarely occurs in isolation. Trivial pulmonary regurgitation is a frequent finding in otherwise normal individuals and is of no clinical significance.

It is classified as mild, moderate, or severe. It may complicate mitral stenosis

Clinical features

• An early diastolic decrescendo murmur at the left sternal edge (Graham Steell murmur)
• The murmur is difficult to differentiate from that of aortic regurgitation

Investigations:

• Echocardiogram, cardiac MRI

Management

-Monitoring in patients with moderate to severe disease

-Severe disease;

• Surgical valvuloplasty
• Valve replacement
