Diastolic compression of the coronary arteries is a rare and likely acquired finding. Previous reports hypothesized that the artery becomes compressed against epicardial and pericardial scarring during ventricular filling, which leads to reduced coronary blood flow and clinical ischemia. We present two cases of isolated diastolic coronary artery compression resulting from contact against postoperative pericardial reflections that became calcified during the course of 10 to 20 years.
冠状动脉舒张期受压是一种罕见且可能为后天获得性的表现。既往报道推测,心室充盈时动脉受压于心外膜和心包瘢痕,导致冠状动脉血流减少和临床缺血。我们报告了两例孤立性舒张期冠状动脉受压的病例,其原因是心包反射在术后 10 到 20 年的过程中发生钙化并与之接触。
