Objective. Behcet's disease (BD) is a chronic, multisystemic disorder characterised by recurrent oral aphtous ulcers, genital ulcers and ocular inflammation. Vasculitis and thrombotic events are the most important causes of mortality. Vena cava thrombosis, pulmonary artery aneurysms, Budd-Chiari syndrome, peripheral artery aneurysms, dural sinus thrombosis and abdominal aorta aneurysms are the other less common vascular manifestations of BD. Cardiac involvement in BD is a rare and life-threatening complication. The aim of this study was to assess the clinical characteristics and outcome of patients with BD who have intracardiac thrombus.
