Takotsubo cardiomyopathy, also known as stress-induced cardiomyopathy or broken-heart syndrome, is a non-ischemic cardiomyopathy that presents as a transient regional systolic dysfunction of the left ventricle with minimal increase in troponins. The pathogenesis of takotsubo cardiomyopathy is not well understood. Some possible theories include increased catecholamines causing sympathetic overdrive, microvascular dysfunction, coronary spasm, or inflammation. The association of herpes simplex virus (HSV) encephalitis with takotsubo cardiomyopathy has rarely been reported with only two cases being described in literature.
