[Long-term results of mitral percutaneous valvuloplasty with Inoue technique. Seven-years experience at the Cardiology Hospital of the National Medical Center "Siglo XXI", IMSS].
2006
UNLABELLED: Since the last decade, percutaneous balloon mitral valvuloplasty with Inoue catheter is considered the treatment of choice for selected patients (mobile valve, no calcification and minimal subvalvular disease) with rheumatic mitral stenosis. OBJECTIVE: We present the seven-year follow-up experience of 456 patients treated with this technique in the catheter laboratory of the Cardiology Hospital in National Medical Center SXXI. MATERIAL AND METHODS: It is a retrospective, transversal and observational study performed with data obtained from January 1994 and December 2000, with a follow-up of 58.5 +/- 26.6 months (range 12-96 mean 22). RESULTS: We achieve an initial success of 82.8%, improvement of initial mitral valve area from 0.9 +/- 0.1 to 1.8 +/- 0.3 cm2, with a gain area from 88 to 106% (p 90%. From these patients, 93.1% remained in NYHA-II or -I functional class and the incidence of restenosis decreased.
