Rare and atypical forms of Tako-Tsubo cardiomyopathy diagnosed by contrast-echocardiography during subarachnoid haemorrhage: confirming the appropriateness of the new Tako-Tsubo classification.

摘要

Although the precise pathophysiological mechanism of reversible left ventricular dysfunction, better known as Tako-Tsubo cardiomyo-pathy (TTC), remains to be defined, it has become accepted as a distinct clinical entity [1]. An almost identical form of TTC has long been known in association with intracranial haemorrhage and it was originally called "neurocardiogenic stunning" [2]. In the original version of the Mayo clinic criteria the presence of intracranial bleeding was considered an exclusion criterion for the diagnosis of TTC; reasonably, this has been finally removed in the recently updated version of the criteria [3].
