Abstract
From January 1981 to June 1994, 17 patients underwent aortic annulus enlargement by a modified Manouguian's technique. A small aortic root associated with stenotic lesions was the main indication. The ages of the patients ranged from 5 to 55 years (mean, 21 ± 14 years). There were 10 males and 7 females. Four had concomitant mitral valve replacement, 2 had open mitral valvotomy, 1 underwent ventricular septal defect closure, excision of a subaortic membrane, and ascending aortic replacement. The aortic roots were enlarged to between 20 to 30 mm. A Dacron patch was used in 16 patients and glutaraldehyde-treated autologous pericardium was used in 1. Two patients (12%) died in the postoperative period, 1 due to hemorrhage and the other due to septicemia. Mitral regurgitation (grade 1) was seen in 1 patient postoperatively but there was no further deterioration on serial evaluation. Four patients were lost to follow-up. Of the 11 followed up over a period of 10 years, 7 were in New York Heart Association functional class I and 4 were in class II.
