Large Left Atrial Thrombus Under Oral Anticoagulation Therapy with Rivaroxiban

1. Abstract A 75 years old male patient, had a lower limb phlebitis treated by Rivaroxiban, presented an increasing dyspnea. A Doppler echography found a left sural deep venous thrombosis (DVT). The Transthoracic and transesophageal echocardiography found a large left atrial tumor, moving randomly across the mitral valve, 100 mm of length and going until the left ventricular apex (Figure 1). The surgical procedure was performed, 24 hours after Rivaroxiban?s interruption.
