横切面箭头示心肌的破裂点。三周前发生过一次心肌梗死，相应部位心室壁非常薄弱，因此第二次心肌梗死发生三天后出现破裂。
In cross section, the point of rupture of the myocardium is shown with the arrow. In this case, there was a previous myocardial infarction 3 weeks before, and another myocardial infarction occurred, rupturing through the already thin ventricular wall 3 days later.
