冠状动脉起源与走行变异较少见。国外研究显示,在接受冠状动脉造影的患者中,起源异常约占0.5%〔1〕。国内的冠状动脉变异造影检出率为1.03%〔2〕。研究显示,多数冠状动脉变异无临床意义。然而,部分冠状动脉变异可导致心肌梗死、心律失常甚至猝死。正确识别冠状动脉变异并检出高危患者具有重要的临床意义。 Variation of coronary artery origin and walking is rare. Foreign studies have shown that in patients undergoing coronary angiography, the origin of about 0.5% [1]. The domestic detection rate of coronary artery angiography was 1.03% 〔2〕. Research shows that most coronary artery disease has no clinical significance. However, some coronary artery variability can lead to myocardial infarction, arrhythmia and even sudden death. Correct identification of coronary artery disease and detection of high-risk patients has important clinical significance.
