Corticosteroid prophylaxis for fetal immaturity in a pregnant patient with atrial myxoma

We report a case of a woman at 32nd gestational week, admitted for resting dyspnea, showing left atrial (LA) myxoma. Cardiac myxomas are the most common primary benign tumors of the heart. The incidence of cardiac myxomas diagnosed in pregnancy is extremely low. In the present case, cesarean delivery and concomitant surgical resection of LA myxoma were both delayed after corticosteroid prophylaxis in order to reduce neonatal cerebral, intestinal, and pulmonary complications. .
