Abstract

BACKGROUND

A nondominant right coronary artery supplies a small portion of the myocardium. Albeit rare, an acute occlusion of a nondominant right coronary artery is believed to be inconsequential with minimal clinical relevance.

CASE PRESENTATION

We present a case of a middle-aged man who presented with chest pain and an electrocardiogram demonstrating anterior ST-segment elevation. An emergent coronary angiogram revealed acute thrombotic occlusion of the proximal nondominant right coronary artery with no significant obstructive atherosclerotic disease in the dominant left coronary circulation. Balloon angioplasty of the occluded vessel followed by implantation of a drug-eluting stent resulted in the resolution of the chest pain and ST-segment elevation.

CONCLUSION

While electrocardiographic ST-segment elevations in the anterior precordial leads are highly suggestive of a left anterior descending artery occlusion, herein, we present a rare case of an acute anterior ST-segment elevation myocardial infarction secondary to a nondominant right coronary artery occlusion.

摘要

背景

非优势型右冠状动脉供应一小部分心肌。尽管罕见，但非优势型右冠状动脉急性闭塞被认为无关紧要，临床意义极小。

病例介绍

我们报告一例中年男性，表现为胸痛，心电图显示前壁ST段抬高。急诊冠状动脉造影显示非优势型右冠状动脉近端急性血栓性闭塞，而优势型左冠状动脉循环中无明显阻塞性动脉粥样硬化疾病。对闭塞血管进行球囊血管成形术，随后植入药物洗脱支架，胸痛和ST段抬高得以缓解。

结论

虽然胸前导联心电图ST段抬高高度提示左前降支动脉闭塞，但在此我们报告一例罕见的因非优势型右冠状动脉闭塞继发急性前壁ST段抬高型心肌梗死的病例。
