Thrombolysis of mobile right atrial thrombi following severe pulmonary embolism

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