Heart mitral valve tricuspid valve slight regurgitation generally no obvious clinical symptoms, without special treatment, regular review dynamic evaluation of the heart ultrasound can be. 1. The mitral valve is the valve that separates the left atrium from the ventricle. With normal heart valves, when the left ventricle contracts, the mitral valve closes completely and blood is ejected into the aorta; when the mitral valve closes incompletely, a portion of the left ventricle’s blood will regurgitate back into the left atrium, but slight regurgitation will not significantly reduce the ejection fraction and will not affect the heart’s pumping function, so there is no need for treatment. 2. The tricuspid valve is a valve between the right atrium and the right ventricle. Similarly, when the right ventricle contracts, the tricuspid valve closes completely and blood is ejected into the pulmonary artery. When the tricuspid valve closes insufficiently, a portion of the right ventricle will regurgitate back into the right atrium, but the slight regurgitation will not significantly reduce the blood flow to the lungs for oxygenation and will not cause the right atrium to become overloaded, so no treatment is needed. 3. Dynamic evaluation of cardiac ultrasound is sufficient in the above cases, but when moderate to severe regurgitation of the mitral or tricuspid valves occurs with significant adverse effects, prompt medical attention is required. Slight mitral tricuspid regurgitation has no obvious clinical symptoms, but when the degree of regurgitation worsens, and symptoms such as dizziness, chest tightness, and panic occur, timely consultation and treatment are needed.
