In a 52-year-old man with severe chest pain of 3 hours duration and ST-segment elevation in leads V1 and V2, a nondominant right coronary artery was recanalized by an intracoronary infusion of urokinase. Coronary cineangiography revealed a total occlusion of the nondominant right coronary artery and no significant narrowing of the left coronary artery. Hemodynamic studies during the acute phase of myocardial infarction demonstrated an increase of right atrial mean pressure in association with normal pulmonary capillary wedge pressure. Following the recanalization, chest pain disappeared and hemodynamic alterations were corrected. The purpose of this report is to document a case of isolated right ventricular infarction due to a nondominant right coronary artery occlusion.
在一名52岁男性患者中，其胸痛剧烈，持续3小时，V1和V2导联ST段抬高，通过冠状动脉内注入尿激酶使非优势型右冠状动脉再通。冠状动脉造影显示非优势型右冠状动脉完全闭塞，左冠状动脉无明显狭窄。心肌梗死急性期的血流动力学研究表明，右心房平均压升高，同时肺毛细血管楔压正常。再通后，胸痛消失，血流动力学改变得到纠正。本报告的目的是记录一例因非优势型右冠状动脉闭塞导致的孤立性右心室梗死病例。
