Why the study?
Takotsubo cardiomyopathy rarely causes left ventricular thrombus and resulting thromboembolism.
Catheter aspiration thrombectomy may be an effective treatment for thromboembolism secondary to Takotsubo cardiomyopathy.
Answers are grounded in this paper and cite their sources.
May indicate efficacy of catheter thrombectomy for renal embolism in Takotsubo; hypothesis-generating and should not change practice.
Takotsubo cardiomyopathy (TC) is a temporal dysfunction of the left ventricle (LV) due to psychological or physiological stress; however, it rarely causes LV thrombus. We report a case of a 49-year-old woman who developed LV thrombi due to TC despite anticoagulation therapy. The thrombi caused acute systemic infarction, with the most severe occlusion being in the right renal artery. The patient underwent percutaneous catheter aspiration thrombectomy of the right renal artery and her renal function recovered shortly after. The results of this case suggest that catheter aspiration thrombectomy is effective in the treatment of thromboembolism in TC.
