Introduction: congenital malformations are causes of disease, sequelae and death in infants and children and constitute in our country the second cause of death during the first year of life. Atrioventricular malformations include several anomalies among which complete forms of the atrioventricular canal are included.
Objective: to describe the case of an infant with complete atrioventricular canal.
Case presentation: 2-month-old infant of rural origin, product of a dystocic delivery, at term, normal weight at birth, with a history of high-risk newborn (mother with mild mental retardation). At 12 days old, he was admitted to the neonatology department with the medical diagnosis of a full-term, normal-weight newborn (maternal case). Several days after birth, physical examination revealed a grade II/VI systolic diastolic murmur. He was admitted to the neonatology intensive care unit for further study and treatment. Complementary tests were performed. Echocardiogram diagnosed complete atrioventricular canal. Support treatment was imposed according to protocol and the patient was transferred to the Agostinho Neto Provincial Hospital.
Conclusions: complete canal septation defect is a rare congenital heart disease generally associated to genetic disorders. In the patient presented, the absence of genetic disorders constitutes an atypical presentation. The form of presentation of this case constitutes a reason for thorough scientific research for specialists and students.
