How to Deal with Pulmonary Valve Regurgitation?

If pulmonary valve regurgitation is mild, no treatment is required, and regular check-ups are sufficient. However, if the regurgitation is severe, surgical treatment to replace the valve is necessary, as it may otherwise lead to new functional failure. It is also essential to examine for any other cardiopulmonary organ pathologies. If there are primary diseases, targeted treatment is required.

Pulmonary valve regurgitation occurs due to incomplete closure of the pulmonary valve, which can be caused by various reasons, such as pulmonary hypertension and rheumatic valvular disease. In general, pulmonary valve regurgitation is not a severe condition and often does not present with clinical symptoms. Mild regurgitation does not require treatment, but further examination is still necessary to ensure no qualitative changes in other cardiopulmonary organs. If there are primary heart diseases, targeted treatment is required. Severe regurgitation requires surgical treatment to replace the valve, as it can lead to heart failure.

Pulmonary valve regurgitation in small amounts refers to the phenomenon where the pulmonary valve does not close completely during the end of the right ventricular contraction and the diastolic phase, leaving a small opening, allowing blood to flow back from the pulmonary artery into the right ventricle. This condition can occur in older individuals due to gradual organ function decline, or it may be caused by high pulmonary artery pressure stemming from left atrial or pulmonary artery pathologies. Mild pulmonary valve regurgitation is often caused by pulmonary hypertension, which, if severe, can lead to right ventricular hypertrophy, further progressing to right and left heart failure. Chronic bronchitis is a common clinical cause of mild pulmonary valve regurgitation due to pulmonary hypertension, and heart hypertrophy resulting from this condition can be severe.
