Successful Conservative Treatment of Cardiac Rupture Associated with Takotsubo Syndrome.

We herein report a 75-year-old woman who was diagnosed with Takotsubo syndrome (TTS) complicated by left ventricular outflow tract obstruction on admission. Treatment with beta-blocker and anticoagulant was started; however, her hemoglobin level decreased gradually, and computed tomography performed one week later revealed hemopericardium. Oozing-type cardiac rupture was suspected; therefore, we discontinued heparin treatment. Finally, she recovered uneventfully without cardiac surgery. It is noteworthy that cardiac rupture may occur with TTS, especially in patients treated with prophylactic anticoagulation therapy for apical thrombus. Furthermore, conservative, careful observation is an alternative approach in patients with oozing-type cardiac rupture associated with TTS.
