How this condition is diagnosed and what test results mean.
Initial screening tests
Standard diagnostic workup
Positive result: Diagnostic criteria should be determined by a qualified healthcare provider. [Content pending medical review.]
Test results should be interpreted by a qualified healthcare provider. [Content pending medical review.]
Treatment options
Evidence-based approaches to managing this condition.
First-line treatments
Balloon pulmonary valvuloplasty
A minimally invasive catheter-based procedure where a balloon is inflated to widen a narrowed pulmonary valve, improving blood flow from the heart to the lungs. This is often the preferred first-line intervention for symptomatic valve narrowing.
Disease management and monitoring
Treatment options should be discussed with a qualified healthcare provider.
Pulmonary valve repair or replacement
Open heart surgery to either repair the native valve or replace it with a mechanical or biological prosthesis. Recommended when valvuloplasty is insufficient or anatomy is not suitable for catheter-based approaches.
Additional treatment options
Symptomatic medication management
Pharmacological therapy to manage associated symptoms such as heart failure, arrhythmias, or pulmonary hypertension that may accompany valve dysfunction. Treatment is tailored to specific symptoms and severity.
medicationSerial echocardiographic surveillance
Regular cardiac imaging to track valve function, chamber dimensions, and pulmonary artery pressures over time. Frequency depends on severity and clinical stability.
monitoringActivity modification and exercise guidance
Tailored physical activity recommendations based on functional capacity and valve severity. Low-to-moderate intensity activities are generally encouraged while avoiding competitive athletics in severe cases.
