Lastly, there is some evidence that TTC may be neurally mediated. Similar transient wall motion abnormalities are seen frequently in patients with subarachnoid haemorrhage, in whom the wall motion abnormality is thought to be due to neurally mediated localised microvascular ischaemia. Histopathological features of the myocardium are very similar, with contraction band necrosis,27 and can be prevented by cardiac sympathectomy.
