Comparison of early results of percutaneous metallic mitral commissurotome with Inoue balloon technique in patients with high mitral echocardiographic scores.

We compared the safety, efficacy, and cost of the newly introduced percutaneous metallic commissurotome (PMC) with the results of Inoue balloon mitral valvuloplasty (BMV) in 80 patients with mitral stenosis (MS). The mean increase in mitral valve area (MVA) was 0.95 +/- 0.
