Four unusual cases of phasic (occurring only in systole or only in diastole) coronary artery narrowing are reported. In two cases, diastolic compression of the left anterior descending coronary artery was due to tight pericardial adhesions in patients with aortic insufficiency; in the third case, systolic compression of two right ventricular coronary branches was associated with hypertrophic cardiomyopathy and a normotensive right ventricle; and in the fourth case, a large aneurysm of the inferior wall of the left ventricle caused systolic compression of the posterior descending coronary artery, which was epicardial. The diagnostic and pathophysiologic characteristics of each case are discussed.
本文报告了4例罕见的阶段性（仅在收缩期或仅在舒张期出现）冠状动脉狭窄病例。其中2例，左前降支冠状动脉的舒张期受压是由于主动脉瓣关闭不全患者的心包粘连紧密所致；第3例，两条右心室冠状动脉分支的收缩期受压与肥厚型心肌病及血压正常的右心室有关；第4例，左心室下壁的一个大动脉瘤导致了心外膜后降支冠状动脉的收缩期受压。文中讨论了每个病例的诊断和病理生理特征。
