1. ObjectiveTo analyze the effect of external valvuloplasty of the superficial femoral vein for primary deep venous valvular incompetence in the lower limbs (PDVI).

2. Methods:Balloon pulmonary valvuloplasty was performed on22consecutive infants with isolated pulmonary valvular stenosis.

3. Development of infundibular stenosis following percutaneous balloon pulmonary valvuloplasty can cancel the effects of the valvuloplasty.

4. Objective To explore the clinical effects of aortic valvuloplasty in treatment of ventricular septal defect(VSD)with moderate or severe aortic valve insufficiency(AI)in children.

5. Methods External valvuloplasty of the femoral vein valve was performed in 26 patients(37 legs) with deep venous valve insufficiency of the legs.

6. Analysis of the effects by percutaneous mitral balloon valvuloplasty in rheumatic mitral stenosis.

7. Percutaneous balloon pulmonary valvuloplasty (PBPV) and balloon angioplasty were performed in 15 children with tetralogy of Fallot (TOF).

8. Objective: To report Clinical Investigation of Gastri Mucosa Valvuloplasty to prevent gastroesophageal reflux after esophagogastrostomy .

9. Conclusion External banding valvuloplasty of superficial femoral vein is an effective and simple procedure with few complications in treatment of primary lower extremity deep vein valve insufficiency.

10. Aim To evaluate the effectiveness of external banding valvuloplasty of superficial femoral vein in the treatment of primary lower extremity deep vein valve insufficiency.

11. Objective To analyze the clinical effect of external valvuloplasty of femoral vein for deep vein valve insufficiency in the lower limbs .

11.

12. Objective To evaluate the effectiveness of external constriction valvuloplasty of superficial femoral vein in the treatment of primary lower extremity deep vein valve insufficiency.

13. Objective:To observe whether percutaneous transluminal ballonmitral valvuloplasty (PTBMV) can improve the pulmonary function of patients with single mitral stenosis (MS).

14. The right ventricular function was studied before and after percutaneous balloon mitral valvuloplasty(PBMV) in 40 patients with rheumatic mitral stenosis.

15. Objective To find a simple and noninvasive method for estimating pulmonary artery systolic pressure (PASP) in patients underwent percutaneous balloon mitral valvuloplasty (PBMV).

16. Objective:To evaluate the safety and efficacy of percutaneous balloon mitral valvuloplasty(PBMV) in patients with rheumatic severe mitral stenosis and thrombus in the left atrial appendage.

17. Objective To study and evaluate the therapeutic effects of external valvuloplasty for deep venous valve insufficiency of the legs.

18. Objective To assess the immediate and long-term results of percutaneous balloon mitral valvuloplasty(PBMV)for treating rheumatic mitral valve stenosis.

19. Methods 50 patients a total 56 lower extremities of the deep veins treated with external constriction valvuloplasty and operation of superficial vein meanwhile are reported.

20. Objective: To evaluate methology and safty of inter-atrial septal puncture in patients undergoing percutaneous balloon mitral valvuloplasty (PBMV).

21. Objective To observe safty and effect of percutaneous balloon mitral valvuloplasty(PBMV) on the patients with rheumatic mitral stenosis complicated with left atrial thrombus.

22. Conclusion Surgical treatment with cardiopulmonary bypass is safer and more effective for some cases of severe pulmonary valve stenosis than percutaneous balloon pulmonary valvuloplasty.

23. Objective To summarize and analyze the clinical effect of 34 mitral insufficiency treated with mitral valvuloplasty.

24. All limbs were performed with superficial venous operation and external valvuloplasty of femoral vein valve.
