Using cryopreserved allogeneic pericardium to repair congenital heart defects in children.

Patches prepared from autologous, allogeneic, or xenogeneic tissues are widely used in the repair of congenital heart defects in children. Since 2002, cryopreserved allogeneic pericardial patches have been prepared in our institution as an alternative to commercially available patches. This study retrospectively reviewed donor and patient data concerning cryopreservation time and the clinical use of the pericardium in 382 children who were operated on at a single center between 2004 and 2021.

Late right pulmonary artery stenosis after arterial switch operation in mirror image dextrocardia and situs inversus totalis.

The operation of D-transposition of the great arteries is performed extremely rarely in patients with mirror image dextrocardia and situs inversus totalis. Therefore, it is not surprising that such unusual anatomy case presents problems with primary operation. We present a case of late right pulmonary artery stenosis after neonatal surgical anatomic correction of mirror image dextrocardia and situs inversus totalis.

Cost-effectiveness of mini-circuit cardiopulmonary bypass in newborns and infants undergoing open heart surgery.

Background And Aim: Miniaturisation of the extracorporeal circuit is a current trend in modern paediatric cardiac surgery. Many investigators stress that reduction of priming volume and artificial surface area of extracorporeal circulation could lead to clinical and economic benefits. The aim of this paper was to evaluate the costs of mini-circuit use in infants undergoing open heart surgery.

Evolving approach to aortic valve replacement in children and adolescents--a preliminary report.

Background: Surgical treatment methods are still controversial in children with congenital or acquired aortic valve dysfunction.

Aim: To evaluate treatment results in children after mechanical or biological valve implantation.

Methods: We analysed a group of 55 children after mechanical valve implantation (group A) and a group of 8 children after Freestyle biological valve implantation (group B).
