				        	Objective To explore the clinic results of our new designed transcatheter valve in valve for the mitral biopro-thesis deterioration.Methods Mitral bioprothesis deterioration patients with high risk for the routine bypass surgery got con-sent.After general anesthesia in the hybrid operation the left ventricle apical puncture was performed with guidance of 3D echo and X-ray.The retro-preset J Valve system was guided into the left atrium and the mitral bioprothesis with the beating heart . Results There were total 9 cases between Jan 2019 to Mar 2019 which had STS score above 6-8.The mitral bioprothesis in-cluded Hancock valve 3 cases, Perimount valve 3 cases, Epic valve 2 cases, Baxiter valve 1 case.The mitral bioprosthesis size included 27 for 6 cases and 25 for 3 cases.The successful implant rate was 100%, mortality rate 0, and all the patients recov-ered well without any main complications.The mean tran-valular pressure was only(8 ±2) mmHg (1 mmHg=0.133 kPa). Conclusion This innovative mitral valve in valve technique with retro-preset J Valve system got very good clinic results and worthy of deep research.
