The relationship between senile aortic valve calcification and coronary heart disease;

Protective effect of chondroitin sulfate on homograft aortic valve cryopreserved in liquid nitrogen;

Experimental study on construction of tissue-engineered heart valve using porcine decellular aortic valve;

In recent years,research has involved percutaneous aortic valve replacement,percutaneous mitral valve reconstruction and even percutaneous pulmonary valve replacement after successful application of percutaneous mitral commissurotomy in clinical practice.

We examined the mechanical behavior of human aortic valve and pulmonary valve by measuring their uniaxial tensile stress-strain, stress-re laxation and fracture behavior.

The first successful human percutaneous implantation of a catheter-based stent valve was accomplished in the pulmonary valve position by Bonhoeffer in 2000.
