The left atrium is the most common location of myxomas, which are benign tumors. Only a few cases of myxomas in pregnancies have been reported. Our thorough medical literature search showed only 17 reported cases in the course of pregnancy. Myxomas during pregnancy and in the preterm period constitute a serious phenomenon that can mimic an early sign of a life-threatening pathology like severe mitral stenosis. We describe a 33-year-old woman, who presented with acute dyspnea to a gynecology center and was referred to our hospital for further evaluation of pulmonary embolism. Transthoracic echocardiography showed a huge left atrial myxoma, and computed tomography scan illustrated paradoxical pulmonary embolism in the left upper lung lobe via a large patent foramen ovale. The tumor required urgent cardiac surgery. In this article, we review causes of dyspnea in pregnancy and the cardiovascular effects of myxomas in pregnancy. We also describe the pathophysiological effects of cardiopulmonary bypass on the mother, fetus, and the feto-placental system during open-heart surgery. We performed a successful surgical resection of a myxoma in a pregnant woman. Given the rarity of such cases, individual multidisciplinary assessment and management strategies are essential.
