Neurogenic stunned myocardium after embolization in two children with vein of Galen aneurysmal malformation

Abstract

Reversible left ventricular dysfunction is observed in adult patients mainly after subarachnoid hemorrhage and is called neurogenic stunned myocardium (NSM). Other forms of brain injuries have also been identified accounting for this condition in adults. In pediatric population especially with specific cerebral diseases, NSM may be underdiagnosed.

Neurogenic Stunned Myocardium in Two Children with Neurological Injury

“…Moreover, it has been described in different neurological conditions, including intracerebral hemorrhage, acute stroke, seizure, and traumatic brain injury. 4 In pediatric cases, neurogenic stunned myocardium has been documented after neurosurgery 5,6 and acute hydrocephalus. 7 Clinical findings in neurogenic stunned myocardium include left ventricular wall motion abnormality, electrocardiographic changes, and elevated myocardial enzymes in the absence of coronary artery disease.…”

Central nervous system (CNS) disease triggering Takotsubo syndrome

“…In some of these cases it is even questionable if the CNS-disorder was in fact the trigger or if other circumstances caused the catecholamine storm. CNSdisorders which have been rarely reported as triggers of TTS include mitochondrial disorders, 39 subdural haemorrhage, 40 removal of a posterior fossa medulloblastoma, 41 vein of Galen aneurysmal malformation, 42 astrocytoma with hydrocephalus, 43,44 hepatic encephalopathy, 45 or exacerbation of a multiple sclerosis (MS).…”
