About congenital heart defects

Congenital heart disease (CHD) refers to any malformation or disease of the heart present from birth and includes structural defects, congenital arrhythmias, and some cardiomyopathies. About 1% of babies are born with a heart or circulatory condition, usually a congenital heart malformation.

Congenital heart problems range from simple to complex. Some heart problems can be watched and managed with medicines, while others will require heart surgery or transcatheter intervention (keyhole techniques) – sometimes as soon as in the first few hours after birth. Survival and medical care for babies with critical CHD has dramatically improved over the past few years due to advances in diagnostic and treatment techniques including identifying cardiac malformations before birth referred to as antenatal diagnosis.

National Congenital Heart Disease Audit (NCHDA)

NCHDA aim’s to provide key quality improvements in outcomes and service delivery for infants, children, adolescents and adults undergoing interventions for paediatric and congenital heart disease, as detailed in the main NCAP aggregate report. The background and history of the NCHDA, including methodology, analytical scope, validation and risk adjustment, is detailed here

NCHDA Summary Report 2023

The audit collects and analyses data from all centres undertaking congenital cardiac surgery, interventional procedures (including electrophysiology) and antenatal detection in the UK and Republic of Ireland between 2019 to 2022.

Quality improvement metrics for NCHDA

NICOR uses quality improvement (QI) metrics in their reports to measure processes and describe outcomes against achievable standards or benchmarks. The NCHDA QI metrics relate to the themes of patient outcomes, safety and clinical effectiveness:
