摘　　要：目的:研究分析双源CT心脏冠脉CT血管造影(CTA)对心肌桥-壁冠状动脉(MB-MCA)的诊断效果。方法:本次研究选取我院在2021年1月—2024年1月期间收治的86例存在冠心病症状或心脏体检患者采取双源CT心脏冠脉CTA检查,分析检查结果。结果:86例患者经检查发现,心肌桥检出23例,检出率26.74%,心肌桥共计32处,发生位置分别在左旋支远段、前降支近段、前降支中段、前降支远段、第一对角支、第二对角支、钝缘支、右冠中段、后降支,数量分别为1处(3.13%)、1处(3.13%)、19处(59.38%)、3处(9.38%)、2处(6.25%)、1处(3.13%)、2处(6.25%)、2处(6.25%)、1处(3.13%);邻近心肌桥近端冠状动脉斑块位于5个位置,共计12处,其中左旋支远段、前降支远段、第一对角支、右冠中段数量相同,均为1处,而前降支中段数量最多为7处。心肌桥按照狭窄程度分为轻度、中度和重度狭窄,长度分别为(23.51±11.98)mm、(27.49±8.20)mm、(18.53±10.11)mm,厚度分别为(0.48±0.70)mm、(2.47±1.33)mm、(3.42±1.50)mm。结论:在MB-MCA中采取DSCT诊断有着较高的应用价值,可清晰显示病变位置、长度及厚度,对MB-MCA做出准确判断,为临床治疗提供了更多的可靠依据。Objective:To study and analyze the diagnostic effect of dual source CT coronary angiography(CTA)on myocardial bridge wall coronary artery(MB-MCA).Methods:In this study,86 patients with coronary heart disease symptoms or undergoing cardiac examinations admitted to our hospital from January 2021 to January 2024 were selected for dual source CT coronary angiography examination,and the examination results were analyzed.Results:After examination,23 cases of myocardial bridges were detected in 86 patients,with a detection rate of 26.74%.There were a total of 32 myocardial bridges,which occurred in the distal left circumflex branch,proximal anterior descending branch,middle anterior descending branch,distal anterior descending branch,first diagonal branch,second diagonal branch,blunt margin branch,middle right coronary artery,and posterior descending branch.The number of myocardial bridges was 1(3.13%),1(3.13%),19(59.38%),3(9.38%),2(6.25%),1(3.13%),2(6.25%),2(6.25%),and 1(3.13%),respectively;The coronary artery plaques near the proximal end of the myocardial bridge are located in 5 locations,totaling 12 locations.Among them,the number of distal left circumflex artery,distal anterior descending artery,first diagonal artery,and middle right coronary artery plaques is the same,all with 1 location,while the maximum number of middle anterior descending artery plaques is 7.Myocardial bridges are classified into mild,moderate,and severe stenosis according to the degree of stenosis,with lengths of(23.51±11.98)mm,(27.49±8.20)mm,and(18.53±10.11)mm,and thicknesses of(0.48±0.70)mm,(2.47±1.33)mm,and(3.42±1.50)mm,respectively.Conclusion:DSCT diagnosis in MB-MCA has high application value,which can clearly display the location,length,and thickness of the lesion,make accurate judgments on MB-MCA,and provide more reliable basis for clinical treatment.
