Repair of chordae tendineae for rheumatic mitral valve disease: a twenty-year experience

摘要: Abstract Sixty-two patients with rheumatic mitral valve disease (mean age 42.2 ± 10.2 years) underwent repair of chordae tendineae between June 1974 and May 1994. Chordal shortening was done in 38 patients, fenestration 17, resection secondary 3, replacement 2, transposition 2. In 41 commissurotomy also done. Ring annuloplasty all patients. The mean follow-up years (range 2 months to 20 years). completeness during the closing interval (January July 1994) 100%. Hospital mortality occurred four (6.5%) nine died late follow-up. actuarial survival curve at 65.8% 10%. Six dysfunction (restenosis 4, insufficiency 2) one aortic (structural deterioration bioprosthesis) reoperation. freedom from reoperation for 73.1% 10.5%. 49 surviving a Doppler echographic study showed area 1.9 0.3 cm . 43 repaired native valve, absent or trivial regurgitation documented 35 mild moderate 8. conclusion, when feasible is stable safe procedure low prevalence However, type reconstructive operation experience surgical team are major considerations successful valve.
