Association between ibrutinib and mid-cavitary Takotsubo cardiomyopathy: a case report and a review of chemotherapy-induced Takostubo's cardiomyopathy

Takotsubo cardiomyopathy (TC) is a rare but increasingly recognized phenomenon, which can occur as a side effect of cancer treatment. We report an interesting case of a 53-year-old woman with non-small-cell lung cancer, who developed TC after chemotherapy with ibrutinib. Echocardiography revealed marked left ventricular dysfunction with apical hyperkinesis and mid-ventricular hypokinesia. Coronary angiogram was normal but did show mid-cavitary akinesis. To our knowledge, this is the first case of TC with ibrutinib. Therefore, TC remains a rare entity, and we present an elegant case of ibrutinib-mediated mid-cavitary Takotsubo cardiomyopathy with a literature review.
