摘要: BACKGROUND Eight patients with severe congenital mitral stenosis underwent double transseptal, double-balloon valvuloplasty; two had isolated stenosis, six additional cardiac defects, and one previous surgical valvotomy. Ages ranged from 0.6 to 36 years (median, 9 years). METHODS AND RESULTS All procedures were tolerated well. After valvuloplasty, the left atrial a wave minus ventricular end-diastolic pressure (LVEDP) gradient was reduced 25 +/- 6 mm Hg 3 (p less than 0.001), valve mean 18 7 8 = 0.003), LVEDP unchanged. marked clinical improvement. Only patient developed significant regurgitation. Two of first four repeat balloon valvuloplasty months later. Follow-up evaluation on 4 54 revealed no recurrence symptoms or increased regurgitation. CONCLUSIONS Double is an effective treatment for many forms stenosis. Mitral regurgitation uncommon after this procedure. The transseptal approach results in trauma septum femoral veins allows easy assessment any residual postvalvuloplasty gradient.
