Diagnóstico tardio de tetralogia de Fallot – relato de caso

Abstract

Congenital heart diseases are defects of the circulatory system present from birth, being divided into cyanotic and acyanotic. Tetralogy of Fallot is the most common cyanotic heart disease characterized by ventricular septal defect, pulmonary stenosis, biventricular origin of aortic valve and right ventricular hypertrophy. The diagnosis is usually performed in the first year of life due to early clinical manifestations in most cases. However, in some cases, the association of other cardiac defects and failures in the health system can contribute to late diagnosis, increasing the likelihood of unfavorable prognostics. Objective: To report a case of an adolescent patient with late diagnosis of tetralogy of Fallot, with systemic complications of cyanosis. It was surgically treated, evolving satisfactorily. Conclusion: Despite the scientific and technological advances in medicine, it is still possible to identify people at older age and with severe comorbidities not diagnosed, as congenital heart defects, resulting in complications or even death if not diagnosed on time. This fact corroborates the need for awareness of health teams for the early identification of suspected cases.
