Current prosthetic replacement for aortic valve disease are far from the ideal. The pulmonary autograft replacement of the aortic valve, associated with a homograft in pulmonary position (Ross' procedure), offers an attractive option in younger patients, with growth potential and long-term survival. In our Institution, between January 1997 and December 1998, 12 patients have undergone this procedure. Aortic regurgitation was the main lesion in 5 cases - associated with significant mitral regurgitation, requiring intervention, in three, Aortic regurgitation associated with sub-aortic membrane - 2 cases, Aortic stenosis - 1 case. Reoperation due to failure of aortic valve reconstruction - 1 case. The ethiology was rheumatic in 83.3% of the patients. The mean age was 12.17 years (± 2.04) (range, 8 to 15 years). 41.66% (5 patients ) were in NYHA Class II and the remaining in NYHA Class III. Echocardiogram was performed for pre-op and post-op evaluation in all cases, as well as post-op cardiac catheterization. The homografts used in this series were preserved in antibiotic solution and used before three weeks. Post-op fever was present in 9 (75%) patients, congestive heart failure in 3 (25%), systemic hypertension in 4 (33.3%), excessive pulmonary secretion in 1 (8.33%) and myocardial ischemia 1 case (8.33%). Post-op cardiac catheterization, one month after surgery, showed absence of aortic or pulmonary regurgitation. All patients but 1 (8.33%) are in NYHA Class I, with no medication. In conclusion, the techniques is effective and adequate for children, but some long-term follow up is necessary for better evaluation of the grafts.
