Abstract
|
|
|
|
Takotsubo cardiomyopathy or stress induced cardiomyopathy is characterized by acute transient left ventricular apical ballooning without significant coronary artery disease. The pathophysiology of Takotsubo cardiomyopathy remains unclear, but it has been suggested that the stress related neurohumoral factors, especially catecholamines, play an important role. Recently, several reports have described an inverted Takotsubo cardiomyopathy, which is characterized by the dysfunction of the basal and mid-ventricular segments sparing the apex of the heart. In this report, we present a case of a 50-year-old female with a transient left ventricular dysfunction in an inverted Takotsubo pattern, that later was diagnosed as a malignant pheochromocytoma.
