Atrial myxoma is the most prevalent primary heart tumor., Clinical manifestations of myxomas are usually nonspecific, and they may present with dyspnea, fatigue, reduced functional capacity, edema, and, eventually, cerebral embolic events with focal neurological deficits. Although they are classified as benign neoplasms, most commonly located in the left atrium, they can cause obstruction of intracardiac blood flow and, when friable, systemic embolism with consequent tissue ischemia.,
In spite of higher prevalence in women (65%), diagnosis during pregnancy is considered uncommon, with greater challenges in treatment and an increased risk of fetal death. We report the case of a pregnant patient with a complication of atrial myxoma that manifested during labor.
