Long Segmental Right Coronary Artery Dissection Successfully Treated by Percutaneous Coronary Intervention

並列摘要


The pathogenic mechanism of acute myocardial infarction in majority is plaque rupture with acute thrombus occluding the culprit vessel, however, spontaneous coronary artery dissection, although rare, may result acute coronary syndrome and a catastrophic outcome. We report a 41-year-old male presenting to our emergency department because of chest pain. The electrocardiogram showed a sinus rhythm with a rate of 76 beats per min, Q wave and ST segment elevation in leads Ⅱ, Ⅲ, and aVF. Emergent coronary angiography revealed a dissection extending from the middle portion of the right coronary artery to the posterior descending branch. Successful percutaneous coronary intervention with stent implantation was performed with an optimal angiographic result.
