Antiphospholipid syndrome is a hypercoagulable state mediated by antibodies (anticardiolipins or lupus anticoagulant) that is characterized by the recurrence of fetal losses and arterial and venous thromboembolic events. Its frequency in patients that present a venous thromboembolic episode, ranges from 4 to 14% [1].

Due to the increased risk of recurrent thromboembolic episodes in these patients, the current guidelines suggest extending antithrombotic therapy after an initial event, probably for life.

The images of Figures 1 and 2 correspond to a 30-year-old woman, with diagnosis of antiphospholipid syndrome that came to the medical office because of stress dyspnea and peribuccal cyanosis, so transthoracic echocardiogram is indicated, showing a large mass (87 mm x 35 mm), hypermobile in the right atrium, that protrudes in the right ventricle through the tricuspid valve (Figure 1A). Moreover, another mobile mass is identified (20 mm x 25 mm), rounded, more dense, in the left atrium, adhered to the interatrial septum (Figure 1B). Both masses are initially assumed as biatrial thrombosis, so it is decided to make a surgical intervention [2-3]. In the surgical act, the tumors are removed from both atria (Figures 2A and B). The histopathological study reports that it is a thrombus in the right atrium and a myxoma in the left atrium.
