Zusammenfassung:Background: Congenital aortic valve (AV) disease is viewed in 2% of the population and in 20 out of 1000 neonates are presented with bicuspid configuration. Treatment of the congenital AV diseases requires multiple interventions. The ultimate goal is to provide adequate close to physiological left ventricle outflow and minimization of regurgitation. The optimal operative management of AV disease in children and young adults remains controversial. AV neocuspidization with glutaraldehyde‐treated autologous pericardium may be a satisfactory alternative in pediatric cardiac surgery. Objectives: The data of the AVNeo procedure results enable a comparative analysis of various AV reconstructive approaches in the pediatric cohort. In this article, we present the comparative study of various techniques in pediatric AV surgery, including the immediate and midterm outcomes of AVNeo, commissurotomy with aortic leaflet augmentation using pericardial patch (“free style” technique), and Ross procedure. Study Design: We conducted a retrospective analysis of the early and midterm results of surgical AV disease treatment of 44 children in 5 cardiac surgery centers from 2014 to 2022. The patients were divided into 3 groups: group I: glutaraldehyde‐treated autologous pericardium AVNeo ( n = 12), group II: “free style” technique ( n = 10), and group III: Ross procedure ( n = 22). We described the immediate and midterm outcomes. The study design was approved by the ethics committees of the participating centers. Results: A total of 44 children after surgical treatment of the AV disease in 5 cardiac surgery centers were included in the study and were grouped as group I: AVNeo ( n = 12), group II: “free style” technique ( n = 10), and group III: Ross procedure ( n = 22). The median follow‐up period was 57 ± 23.8 months. In‐hospital mortality was 4.5% ( n = 2). In the midterm follow‐up, the peak pressure gradient was 18.45 ± 4.63 mmHg for group I and 8.9 ± 1.6 mmHg for group III ( p = 0.00001), respectively. The cumulative freedom from reoperations was 100%, 30%, and 95.2% for 40 months of follow‐up and 100%, 30%, and 83.4% for 70 months of follow‐up in I, II, and III groups, respectively. No cases of midterm mortality were detected in all groups. Conclusion: The AV neocuspidization with glutaraldehyde‐treated autologous pericardium has an enormous advantage in pediatric AV surgery, significantly surpassing the freedom from resurgery of repair procedures and having comparable resu
