Consensus on early detection of congenital heart disease

Congenital heart diseases are the most frequent birth defects, and one of the main causes of perinatal morbidity and death. Early diagnosis allows a timely treatment and improves the patients' prognosis. Early detection includes screening studies during the first and second trimesters of pregnancy, a neonatal complete clinical examination and the neonatal pulse oximetry test. The aim of this consensus is to present recommendations for early detection and diagnosis of congenital heart disease.
