Recurrent second-trimester intrauterine fetal death due to undiagnosed atrioventricular block: a case report
Fetal cardiac abnormalities are one of the common causes of non-immune fetal hydrops. Early diagnosis and treatment may prevent the late consequences that can occur as heart failure and intrauterine fetal death. Herein we report the case of a 32-year-old patient with a history of recurrent second trimester intrauterine fetal death. She presented with fetal hydrops at 23 weeks. A detailed echocardiography revealed that the fetus had a third degree atrioventricular block and advanced hydropic changes due to heart failure. Corticosteroid therapy was started but the fetus died in utero after 2 weeks.
