Transmitral thrombectomy to treat a patient with Takotsubo cardiomyopathy

Abstract

A 68-year-old woman with a history of bipolar disorder was admitted to another hospital with a gastric ulcer. On admission, Takotsubo cardiomyopathy was suspected because her electrocardiogram was abnormal and the characteristic left ventricular wall motion was apparent. On hospital day 11, echocardiography revealed a thrombus in the apex of the left ventricle. She was transferred to our hospital and heparin treatment was commenced. On follow-up echocardiography, the left ventricular wall motion had normalized but thrombus mobility had increased. Thrombectomy was performed via a transmitral approach with endoscopic assistance. Endoscopy allowed excellent visualization of the intracardiac structure.
