Cor triatriatum sinistrum in a Nigerian adult

Abstract

Classical triatriatum sinistrum or cor triatriatum sinistrum is a rare congenital heart disorder arising from the left atrium being divided into two chambers and may present with undistinguishing features such as exertional dyspnea, hemoptysis, and orthopnea. It has been scarcely reported among adult Nigerians. The case being reported presented at an unusual age of 30 years. Most cases previously reported were in children. Definitive treatment is a corrective surgery with an excellent outcome. Nonintervention could have a catastrophic outcome. Therefore, there must be a high index of clinical suspicion and early diagnosis. This report is to increase awareness of such condition.
