Abstract: the choice of valve replacement or valve repair is mainly determined by the nature and extent of the lesion. In addition, the surgeon's experience and technology in the judgment of the disease, especially in the repair of the valve also play an important role.

I do not want to change valve, can you repair valve?

The choice of valve replacement or valve repair is mainly determined by the nature and extent of the lesion. In addition, the surgeon's experience and technology in the judgment of the disease, especially in the repair of the valve also play an important role. Many outside the hospital must valve replacement patients with congenital heart disease, rheumatic heart disease and traumatic valvular injury, where the success of the valve repair, not only save the cost, but also avoids the defects after valve replacement for life taking anticoagulants, especially beneficial to the growth and development of children.

What is valvular stenosis? What is valvular regurgitation?

The heart has four valves that control the flow of blood through the coordination of opening and closing. The role of the valve is similar to the valve of the water supply system, valve stenosis is a small valve to limit the flow of water, the valve is not completely closed valve leakage caused by water reflux. Whether valvular stenosis or insufficiency, or coexistence of stenosis and regurgitation, both increase the burden on the heart and the long-term development of heart failure.

What are the types of valves? What are the disadvantages?

The artificial heart valve is divided into two kinds: biological valve and mechanical valve. The biological valve is made of biological tissue material. Biovalve thromboembolism rate is low, without anticoagulant therapy, avoid the complications caused by taking anticoagulant drugs, but its durability than mechanical valve, the average working life of 15 years, so for young patients may face two valve replacement surgery may be. The mechanical valve is made of advanced composite materials and titanium alloy steel, with strong durability, and require life-long anticoagulation; daily taking anticoagulant drugs, periodically anticoagulation index, ensure anticoagulation in a safe range; valvular heart disease after surgery anticoagulation could happen if embolism or bleeding risk.
