Moderate tricuspid regurgitation does not cause pulmonary hypertension; moderate mitral regurgitation does.
The tricuspid valve is a valve located between the right atrium and the right ventricle, and since blood flows out of the right ventricle before entering the pulmonary artery, the pressure in the pulmonary artery does not increase in patients with moderate tricuspid regurgitation. However, moderate tricuspid regurgitation can lead to increased preload on the right atrium, and long-term lesions can lead to right heart failure and stasis in the physical circulation.
Moderate mitral regurgitation can cause pulmonary hypertension. The mitral valve is a valve located between the left atrium and the left ventricle, and moderate mitral regurgitation can lead to increased preload on the left atrium, and long-term lesions can lead to left heart failure, which in turn can lead to pulmonary stasis and pulmonary hypertension.
If examination reveals moderate tricuspid regurgitation, please follow the doctor’s instructions for treatment.
