PG - 003757 LID - 10.12890/2023_003757 [doi] LID - 003757 AB - According to the modified World Health Organization (WHO) classification, mechanical valves pose a high maternal risk and complications for pregnant women with heart disease. Left atrial appendage aneurysm (LAAA) is a rare condition that can manifest clinically in several ways or remain silent for a long time and can be either congenital or acquired. We present the case of a pregnant woman who had a LAAA discovered several years after her last mitral valve replacement. LEARNING POINTS: Left atrial appendage aneurysm is a rare entity and, in most cases, is congenital due to poor myocardial contractility of dysplastic pectinate muscles.Clinical manifestations range from an asymptomatic course with an incidental finding on echocardiography up to serious sequelae such as cardioembolic manifestations.The treatment approach includes a conservative strategy using anticoagulation and a surgical strategy with aneurysmectomy.
