Overview
Pulmonary valve regurgitation may be classified according to pulmonary valve morphology and severity of the disease. According to the pulmonary valve morphology, it may be classified into primary and secondary or functional regurgitation. Severity of disease may classify into mild, moderate and severe disease.[1][2][3]
Classification
Pulmonary valve regurgitation is classified into the following types based on the morphology of the valve and severity of the disease:
Based on the Pulmonary Valve Morphology
Pulmonary valve regurgitation is classified into primary and secondary types based on the involvement of the pulmonary valve
- Primary pulmonary regurgitation: The pulmonary valve morphology is affected. Isolated PR is very rare and is most commonly associated with other congenital heart diseases.[1]
- Secondary or functional pulmonary regurgitation: The pulmonary valve function is normal. Conditions such as pulmonary hypertension and pulmonary artery aneursym cause dilation of the valve annulus resulting in regurgitation.[2]
Based on the Severity
Pulmonary valve regurgitation is classified into three categories based on the severity of the regurgitant jet demonstrated on the [[2D echocardiography.[3]
- Mild: Normal valve morphology and usually asymptomatic
- Moderate: Normal to abnormal valve morphology with mild symptoms
- Severe: Abnormal valve morphology with significant symptomatology
