[General surgery and closed mitral commissurotomy: when necessity makes the rules].
Since emergency transfer of patients from Africa to European cardiovascular facilities is difficult, surgeons at the Principal Hospital in Dakar, Senegal, have reevaluated closed mitral commissurotomy. The purpose of this study was to ascertain patient selection criteria, optimal operative conditions, immediate and middle-term outcome, and cost of closed mitral commissurotomy. From June 1995 to March 1998, closed mitral commissurotomy was carried out on 21 patients (13 women and 8 men). Inclusion criteria were symptomatic mitral stenosis with a mitral surface less than 1.5 square centimeters. Exclusion criteria were associated valve disease, Wilkins score higher than 8, severe pulmonary artery hypertension, and evidence of mitral thrombus. One patient died on the fourth postoperative day and one patient developed transient hemiparesis. Twenty patients showed significant functional improvement. Mean mitral surface increased from 0.87 to 1.8 square centimeters. Follow-up at one-year confirmed stable results. Only one patient developed grade 3 mitral insufficiency but it was well tolerated and did not require valve replacement. The cost of the procedure was 1,000,000 F CFA in second category and 820,000 F CFA in third category. The findings of this study show that closed mitral commissurotomy can be performed without circulatory assistance equipment in African facilities such as the Principal Hospital in Dakar, that immediate and middle-term results are excellent, and that African surgeons should continue to learn the technique.
