A small amount of regurgitation of the pulmonary valve is a heart condition.
Normally, blood from the right ventricle passes through the pulmonary valve into the pulmonary artery when the heart contracts, and when the heart diastoles, the pulmonary valve closes and the blood does not regurgitate into the right ventricle. When the pulmonary valve closes insufficiently due to various reasons, blood regurgitation occurs, which is called pulmonary valve regurgitation.
When the regurgitant flow is small, there are usually no clinical symptoms. When the regurgitant flow is large, it will cause the right ventricle preload to increase, which will slowly lead to right ventricular hypertrophy, right heart failure, and then to total heart failure.
Clinically, the most common cause of small amounts of pulmonary regurgitation is pulmonary hypertension caused by chronic pulmonary heart disease. In addition lesions of the pulmonary valve itself and lesions of the left atrium may cause pulmonary regurgitation. In treatment, the main focus is on treating the cause of the disease.
When you find pulmonary valve regurgitation or other cardiac discomfort, you should pay attention to it and go to the hospital in time for a comprehensive examination and a clear diagnosis, so as to provide a basis for the subsequent treatment.
