Overview
Pulmonary valve regurgitation (PR) may be classified according to etiology of the regurgitant flow, severity of the disease and chronicity. Based on the etiology of the regurgitant flow, PR may be classified into primary and secondary/ functional types. The severity of the disease may classify into mild, moderate and severe disease. New York Heart Association's (NYHA) functional classification helps to gauge the severity of the heart failure which is a complication of PR. The severity of PR can be assessed by utilizing the American Heart Association and American College of Cardiology (AHA/ACC) staging of valvular heart disease (VHD).
Classification
Pulmonary regurgitation (PR) may be classified into subtypes based on the etiology of the regurgitant flow, severity of the disease and chronicity.[1]
Based on the Etiology
Pulmonary regurgitation (PR) may be classified into two subtypes based on either intrinsic or extrinsic factors involved in the development of the disease:
- Primary pulmonary regurgitation[2]: The valvular pathology is the cause of PR. Isolated PR is very rare and is most commonly associated with other congenital heart diseases.
- Secondary or functional pulmonary regurgitation[3][4][5]: The pulmonary valve function is normal. Conditions such as pulmonary hypertension and pulmonary artery aneurysm cause dilation of the valve annulus resulting in regurgitation. Secondary PR is more common than primary PR.
Based on the Severity
Pulmonary valve regurgitation may be classified into three categories based on the severity of the regurgitant flow:[6][7]
| Severity | Mild | Moderate | Severe |
|---|---|---|---|
| Valve morphology | Normal | Normal to abnormal | Abnormal |
| Symptom status | Usually asymptomatic | Mild symptoms | Significant symptoms |
| Causes | Physiologic PR | Secondary causes of PR (such as pulmonary artery dilation) |
Post procedure (such as valvulotomy) or anatomic abnormalities of the valve |
Based on the Chronicity
Pulmonic regurgitation (PR) may be classified into two subtypes based on the chronicity of the disease. Chronic diseases are broadly defined as conditions that last 1 year or more.[8]
- Acute PR: Acute PR may occur due to infective endocarditis and blunt chest trauma with direct injury to heart structures specially among patients with abnormal dilation of pulmonary arteries.[9]
- Chronic PR: Regurgitation through the pulmonic valve usually develops progressively after pulmonic valvotomy post pulmonary valve stenosis repair or TOF repair.[9]
Other Classifications
- According to the 2018 ACHD guidelines, moderate or greater pulmonary valve regurgitation lies under moderate complexity according to ACHD (adult congenital heart disease) anatomic and physiological classification.[10]
- Pulmonic regurgitation may lead to right and eventually left heart failure. New York Heart Association's (NYHA) functional classification helps to guage the severity of the heart failure via physical disability of the patient. To read more about the NYHA classification click here.
Staging
According to the American Heart Association and American College of Cardiology (AHA/ACC), the staging of valvular heart disease (VHD) is based on the progression of the disease. Although the staging has not been specified for PR, it is a useful tool to access the disease course.[11]
- Stage A (at risk) : Patient has developed risk factors for VHD. Asymptomatic patient. Development of pulmonary hypertension (PAH) as a risk for PR is an example.
- Stage B (progressive): Patient has developed mild-moderate VHD. Asymptomatic patient.
- Stage C (asymptomatic severe): Patient has developed severe VHD. Asymptomatic patient but exercise test can confirm symptom status.
- Stage D (symptomatic severe): Patient has developed severe VHD. Symptomatic patient such as heart failure symptoms.
