Popis: | From November 1987 to May 1998, 16 patients with a small aortic annulus underwent patch enlargement of the aortic valve by Nicks' technique (in 9) or Manouguian's method (in 7). The mean age of the patients was 40 years (range, 22 to 58 years), mean body surface area was 1.54 m2 (range, 0.95 to 2.05 m2), and 11 were female. Concomitant procedures were mitral valve replacement in 4 cases, tricuspid commissurotomy and De Vega annuloplasty in 2, and one case each of patent ductus arteriosus ligation and coronary bypass. Aortic annular sizes were 15 to 19 mm (mean, 17.4 mm) preoperatively and 20 to 24 mm (mean, 22.1 mm) after the procedure. Two patients (12.5%) died in the early postoperative period. Peak pressure gradients across the prostheses were 15 to 22 mm Hg (mean, 19.4 mm Hg) on echocardiography. The mean duration of follow-up was 32.85 months (3 months to 8 years) and it was 92.8% complete. There were no late deaths. Mitral valve function was good except in one patient who had minimal mitral regurgitation after Manouguian's procedure. Both methods were found to be effective and reliable and should be performed when there is a risk of patient-prosthesis mismatch. |
