Method: The modfied Inoue method was performed. Results: Effective PBMV was performed in 344 cases, the success rate was 98.3%:mitral area assessed by 2 dimenrional echocardiography (1.11±0.29 to 2.19 ±0.40cm 2, P <0.01 ). One hundrad and five patients were followed at a mean (46.7± 26.3 ) months (range 9 months to 8.5 years). after procedure restenosis was 11.4%(12/15), death 2.9 %(3/105, cerebral embolism in 2, congestive heart failure in 1; mitral valve replacement in 3.8%(4/105). Conclusions: percutaneous mitral commissurotomy provided excellent immediate and lale clinical results.展开更多

METHODS:The effects of cilostazol to the expression of lectin-like oxidized low-density lipoprotein receptor-1(LOX-1)at mRNA and protein levels,superoxide generation and neointimal hyperplasia in the rat carotid artery after balloon injury were examined.展开更多
