⇓Enhanced computed tomography revealed both calcification of the pericardium (white arrows) and a largely right atrial thrombus (dark arrows) in a 53-year-old Japanese man who had had several episodes of systemic and pulmonary embolism (A). At operation, an organized right atrial thrombus (65 g; white arrows in B) and calcified pericardium were successfully removed. There was no left atrial thrombus. Right atrial thrombus formation was considered to be due to hemostasis in the markedly dilated right atrium secondary to decreased diastolic compliance and to atrial fibrillation. After surgery, anticoagulation therapy with warfarin was given to prevent the recurrence of thromboembolism. RA indicates right atrium; RV, right ventricle; LA, left atrium; LV, left ventricle; and SVC, superior vena cava.
