PURPOSE: To present immediate results of percutaneous mitral valvuloplasty (PVM) with Inoue balloon for the treatment of mitral stenosis.
METHODS: One hundred and twelve consecutive patients mean age 31.26 +/- 9.5 years, 82% females, the majority in functional class III/IV (69%) underwent percutaneous mitral valvuloplasty (PVM) with Inoue balloon. The procedure was undertaken by the transseptal technique.
RESULTS: PMV achieved significant reduction in mean left atrial pressure pre 24.57 +/- 5.37 post 12.36 +/- 4.82, mitral gradient pre 15.31 +/- 4.28 post 3.48 +/- 2.09 and increased mitral valve area pre 0.88 +/- 0.12 post 2.0 +/- 0.28 (P < 0.001). An increase of at least 25% of the mitral valve area with a final result greater than 1.5 cm2 was obtained in 96% of the cases. Cardiac tamponade occurred in five cases (4.4%). In 4 a successful treatment was accomplished in the catheterization laboratory. Significant mitral regurgitation was seen in one case (0.9%) and there was one death (0.9%).
CONCLUSION: The results of this series attest to the effectiveness of the PMV with Inoue balloon in selected cases of mitral stenosis.
