Abstract
Objective: To build a grounded and uniform knowledge to carry out a medical quality practice, through theoretical foundation and critical analysis on the importance of early diagnosis of congenital heart disease. Methods: This study is a literary review, integrative and experimented by its authors, whose elaboration took place through the following steps: identify the theme and select the research question, search for articles in digital databases, analyze them with the application of criteria for inclusion and exclusion of studies, and discussion of the results obtained by the journals. Results: It can be inferred that the best form of early identification of cardiac anomalies is through prenatal ultrasound screening and, for a more accurate and confirmatory diagnosis, fetal echocardiography. Final considerations: Confirm whether an early diagnosis research is carried out in order to provide the patient with adequate treatment, quality of life and reduction of morbidity, highlighting the need to include tests such as ultrasound and fetal echocardiography in prenatal screening programs.
