Abstract
A 48-year-old female underwent emergency surgery for an undetermined mass in the right atrium associated with bilateral pulmonary artery emboli. Under deep hypothermic circulatory arrest, a large gelatinous mass was excised from the right atrium, and large embolic lumps were removed from both main pulmonary arteries. Histopathological testing of excised specimens confirmed the diagnosis of a vascularized myxoma. At 6 months of follow-up, repeated transthoracic echocardiography has not shown any signs of local recurrence or elevated pulmonary artery pressure. The potential for right atrial myxoma as a source of pulmonary embolization should be borne in mind, as this potentially fatal yet curable condition demands emergency surgical intervention.
