ВИКОРИСТАННЯ АУТОПЕРИКАРДУ ДЛЯ ПЛАСТИКИ СТУЛОК АОРТАЛЬНОГО КЛАПАНА У НОВОНАРОДЖЕНИХ І НЕМОВЛЯТ

Introduction. The pathology of the aortic valve in neonates and infants is an important problem in cardiac surgery, since the fibrously modified and dysplastic valve is difficult to apply to plastic. Objective. This article analyzes the results of plasty of aortic valve with autopericardium in neonates and infants which were operated in our Center. Materials and methods. For the period from 2009 to 2016, 10 patients under the age of 1 year were exposed to open aortic valvuloplasty with extension or replacement of aortic cusps with autopericardium. Eight of 10 patients have undergone balloon vulvuloplasty in the newborn period. Among the 10 patients, 7 (70%) had a fresh autopericardium, 3 (30%) - autopercicardium treated with glutaraldehyde. The median age was 1.77 months (from 6 days to 11.5 months), two of the 10 patients were newborns. Average weight 4.8 ± 1.9 kg (from 2.9 to 8.4 kg). Results. During the operation in 5 (50%) patients were performed the extension of leaflet with autopercicardium and in 5 (50%) was made replacement of one or two leaflets with autopericardium. Eight patients (80%) out of ten had reoperations at the aortic valve, the median time of reoperation was 3 years (from 0 to 5 years). There was no immediate mortality, the long-term mortality was 1 (10%). Conclusions. Freedom from reoperation after plasty with autopericardium was 20%. Most of the patients 8 (80%) who were operated using autopericardium underwent 12 operations in the remote period. Thus, the plasty of the aortic valve with pericardium is associated with a high risk of re-interventions.
