How Do Heart Valves Work During Heart Contraction and Relaxation?

2. Heart valves work through blood flow and heart contraction. Normally, blood flow is unidirectional, and heart valves ensure the stable, one-way flow of blood without reverse flow. Heart valves are valves that open and close unidirectionally. When the heart contracts, the heart valves close, and blood flows from the atrium into the ventricle. When the heart relaxes, the heart valves open, and blood flows from the ventricle into the arteries. The opening and closing of heart valves ensure that blood always flows in one direction.

3. When heart valves are abnormal, with stenosis or incomplete closure, it can lead to gradual enlargement of the patient's heart and decreased heart function, resulting in heart failure and potentially death in severe cases. At this point, patients need to seek medical treatment promptly. Patients can take medications such as Nitrendipine Tablets and Enalapril and Hydrochlorothiazide Tablets according to their doctor's advice. For severe cases, heart valve repair, heart valve replacement, or interventional surgery may be performed under a doctor's guidance.
