ANALYSIS OF PERCUTANEOUS BALLOON MITRAL VAVULOPLASTY WITH 8 CASES

According to the method of Inone, percutaneous ballon mitral vavuloplasty(PBMB)wassuccessfully done in rehumatic heart valvular disease: 3 cases of simple mitral stenosis, 3 cases of mitralstenosis with associated mild mitra1 regurgitation, 2 cases of mitral stenosis with associated mild aortic re-gurgitation- After the PBMB: the mitral valve area (MVA) enlarged (P 0. 01 ), the mean pulmonaryartery and the left artial pressure decreased significantly (P 0. 01 ), the left ventricular functi0n of somepatients also improved. The subjectS' preparati0n before PBMB, the method of transseptal and the choiceof diameter of Inone balloon are the key factors in increasing success rate and reducing complication.
