Guidelines for the management of neonates and infants with hypoplastic left heart syndrome: The European Association for Cardio-Thoracic Surgery (EACTS) and the Association for European Paediatric and Congenital Cardiology (AEPC) Hypoplastic Left Heart Syndrome Guidelines Task Force

The IPCCC is a standardized international system of paediatric and congenital cardiac nomenclature that should be used in all registries, databases and research studies in the domain of paediatric and congenital cardiac care, including those related to HLHS. This recommendation is level 1 class C [15, 16, 700]. Multi-institutional databases and registries allow benchmarking of data concerning death, patterns of practice, morbidity and postoperative length of stay [540]. As a level 1 class C recommendation, all paediatric and congenital cardiac teams should routinely assess their own data against national and international benchmarks using multi-institutional databases and registries [540, 697–699, 701].
