Possibility of hybrid surgery for haemodynamic correction in a child with left heart hypoplasia syndrome: clinical observation

Owing to the development of prenatal diagnosis and interventional cardiology, newborns can survive complex palliative surgical procedures. Modern methods make it possible to change the principles of treatment for children undergoing haemodynamic correction, the last surgery being Fontan operation, and also stimulate the development of hybrid interventions (catheter procedures and surgical operations in the neonatal period). This article presents the dynamic monitoring of a child diagnosed with left heart hypoplasia syndrome, who underwent Norwood surgery at the age of 2 weeks, followed by restenosis of the distal anastomosis and balloon dilatation of neo-aorta restenosis with installation of a cobalt-chromium balloon-expandable stent (Andrastent XL) along with pararectal left-side access to the infrarenal section of the aorta at 11 months in order to reduce surgical risk and prepare for the next stage of correction (Glenn and Fontan operations).
