title: [Percutaneous mitral commissurotomy with Inoue balloon. Short-term results. Initial experience at the Ignacio Chavez National Institute of Cardiology].
abstract: Percutaneous transvenous mitral commissurotomy (PTMC) using balloon catheters has emerged as an alternative to surgery for patients with mitral stenosis. This report details our recent experience of PTMC with the Inoue balloon in 20 consecutive patients with mitral stenosis from april 2 to july 27, 1991. Mean age was 35.6 +/- 9.5 years. Mitral valve area increased form 1.04 +/- 0.3 to 2.32 +/- 0.5 cm2 (p less than 0.0001). Mitral valve gradient decreased from 19.2 +/- 8.8 to 6.6 +/- 2.3 mmHg. (p less than 0.0001). Two patients developed mitral regurgitation greater than 2+/4 after the procedure. In none the residual left to right shunt was greater than 1.2L. There was no mortality. We conclude that in selected patients, excellent results are obtained PMTC with the Inoue balloon. Complications are minimal.
