Abstract:
Abnormal origin of coronary artery is a rare clinical manifestation in cardiovascular disease,among which the abnormal origin of left circumflex artery accounts for 0.022％-0.024％of all coronary angiography patients.Cases of abnormal origin of the left circumflex artery combined with acute occlusion are even rarer.Timely and effective strategies and methods for finding abnormal openings during surgery are crucial for completing interventional treatment.This case reports a rare left circumflex artery anomaly originating from the absence of coronary sinus and acute occlusion of the left circumflex artery leading to myocardial infarction during coronary intervention treatment.The patient experienced sudden chest pain and was admitted to the hospital.The electrocardiogram showed elevated ST segments in the lower and posterior walls.The acute coronary angiography showed only the left main trunk,left anterior descending branch,and right coronary artery(thrombolysis in myocardial infarction blood flow grade Ⅲ),but no left circumflex branch No left circumflex branch was found in the left and right coronary sinuses.Non selective angiography was performed at the root of the ascending aorta,and an abnormal opening of the left circumflex branch was finally discovered in the non coronal sinus.This case discusses common sites of abnormal origin of the left circumflex branch,strategies,methods,and interventional treatments for finding abnormal openings.
