title: Resolution of left ventricular thrombus by rivaroxaban.
abstract: Intracardiac thrombus is a potentially life-threatening condition, with a high risk of embolic complications. Although vitamin K antagonists have been traditionally used for the treatment of intracardiac thrombus, they have relevant disadvantages that limit their use. Rivaroxaban is a once daily oral anticoagulant, currently indicated for the prevention of stroke and systemic embolism in patients with nonvalvular atrial fibrillation, and for the prevention and treatment of venous thromboembolism. We present the case of a 78-year-old man with nonvalvular atrial fibrillation, heart failure and creatinine clearance of 40 ml/min, anticoagulated with rivaroxaban 15 mg/day as the patient had very difficult access to hematologic controls. The transthoracic echocardiogram showed dilated left ventricle, severe left ventricular dysfunction and two images of thrombus, which disappeared after 4 weeks of treatment with rivaroxaban. To our knowledge, this is the first case reported regarding the resolution of left ventricular thrombosis with rivaroxaban.
