[Interauricular communications in children: diagnosis and treatment, about 49 cases at the Children?s University Hospital in Dakar]. / Les communications interauriculaires chez l'enfant: diagnostic et prise en charge à propos de 49 cas aux CHU pédiatriques de Dakar.

Interauricular communication (IAC) is the second most important congenital heart disease in children. It accounts for 6-8% of congenital cardiac malformations in children. However, many questions are still open about this pathology. Thus, this study aims to report the prevalence rate of IAC in hospital but especially to describe its clinical, paraclinical and therapeutic aspects. For this purpose, we conducted a retrospective descriptive study. Data were collected by means of a questionnaire and then entered and analyzed in Sphinx (V5). The prevalence in Hospital was 2x1000. The average age of patients was 37 months, the sex-ratio was 0,75. No prenatal diagnosis was made. Parental consanguinity was detected in 30% of cases. Respiratory infections were found in 24% of cases. Cardiomegaly was found in 35 cases with hypervascularization in 63% of cases. Ultrasound showed a predominance of ostium secundum; wide IAC was found in 63% of cases. Pulmonary stenosis was the most important associated heart attack. Pulmonary arterial hypertension was found in 63% of the cases. Treatment was based on diuretics, which were largely used and only 7 children underwent surgery. Evolution was favorable in 39 patients reflecting a rate of 79%. Early diagnosis of IAC should be improved as well as surgical treatment of IAC affecting infants.
