title: Takotsubo cardiomyopathy and canalith repositioning procedure for benign paroxysmal positional vertigo.
abstract: BACKGROUND
  Takotsubo cardiomyopathy, also known as left ventricular apical ballooning syndrome, ampulla cardiomyopathy, or transient left ventricular dysfunction is characterized by chest pain, electrocardiographic changes, transient left ventricular apical aneurysm, and normal coronary arteries. Takotsubo is a round-bottomed, narrow-necked Japanese octopus trap and lends its name to takotsubo cardiomyopathy because of its resemblance to echocardiographic and ventricular angiographic images of the left ventricle in this condition. This appearance takes its source from peculiar, transient regional systolic dysfunction involving the left ventricular apex and mid-ventricle with hyperkinesis of the basal left ventricular segments. Benign paroxysmal positional vertigo (BPPV) is the most common cause of vertigo caused by peripheral vestibular dysfunction. The symptoms of BPPV are attributed to intralabyrinthine particles, presumed displaced otoconia. Thus, the treatment recommended for BPPV is head repositioning maneuvers.
  
  
  OBJECTIVE
  To present the first takotsubo cardiomyopathy case in the English literature related to BPPV undergoing canalith repositioning procedure.
  
  
  CONCLUSIONS
  This report will provide additional information for physicians encountering acute-onset chest pain and vertigo. It will also expand the spectrum of clinical correlates of the increasingly well recognized but poorly understood syndrome, takotsubo cardiomyopathy.
