Abstract
Thrombolysis may favorably affect the clinical outcome of mobile right atrial thrombus following pulmonary embolism (PE). We report the case of three patients with mobile right atrial thrombus following PE, in whom fibrinolysis was performed. Atrial mass disappeared on the control echocardiogram, but control ventilation perfusion scan showed new perfusion defects in all patients. Thrombolysis seems successful for the treatment of patients with mobile right atrial thrombus following PE; however, recurrent PE may be induced by fibrinolysis. This may affect the benefit of such therapy and should be taken into account when using this therapeutic treatment.
