ABSTRACT: Partial atrioventricular canal is a rare congenital heart defect. Its diagnosis in adulthood remains exceptional, especially in countries with limited resources where early detection is not systematic. We report the case of a 22-year-old female patient, with no pathological history having consulted for stress dyspnea evolving for seven years. Clinical and paraclinical explorations had concluded to a partial atrioventricular canal. A curative surgical correction had been successfully performed. The immediate postoperative evolution was favorable, with no residual leaks or shunts. This case illustrates the diagnostic and therapeutic complexity of partial atrioventricular canals discovered in adulthood, especially in resource-limited settings. It highlights the need for early diagnosis and management, combined with appropriate technical platforms, to improve the prognosis of these rare abnormalities.
