title: In vitro simulation research on the hoop stress of myocardial bridge--coronary artery.
abstract: OBJECTIVE
  The aim of this study is to investigate how the myocardial bridge oppression affects the hoop stress of mural coronary artery.
  
  
  METHODS
  The "myocardial bridge - coronary artery" simulative device records the hoop stress which is changed by adjusting the external pressure of the simulated coronary artery and the oppression degree of the respectively.
  
  
  RESULTS
  Simulation experiment in vitro indicates that the abnormal hoop stress mainly occurs in the proximal end of mural coronary artery. As the oppression degree of myocardial bridge increases, the mean and the oscillatory value (maximum-minimum) of hoop stress in the proximal end increase markedly.
  
  
  CONCLUSIONS
  The "myocardial bridge - coronary artery" simulation device can provide an experiment method of studying the hoop stress influence on mural coronary artery in vitro.
