Abstract:
Objective To analyze the CTA features of asymptomatic myocardial bridge.Methods The CTA images of 69 cases with asymptomatic solitary myocardial bridge were studied retrospectively, and CTA images of 60 cases with symptoms as the contrast group.The type, age, thickness of myocardial bridge, mural coronary artery length and diameter changes of each cases of two groups were analyzed.Results In the study group, 51 cases of 69 (74%) were superficial style, while 18 cases were deep type (26%).In the contrast group, the superficial and deep style were 13 (22%) and 47 (78%) respectively.The mean age,thickness of myocardial bridge,mural coronary artery length and the diameter of mural coronary artery were (53.01±11.17) years old,(1.25±1.16) mm,(21.33±7.32) mm,(2.86±0.45) mm and (51.36±9.31) years old,(1.45±1.87) mm,(20.07±6.60) mm and (1.37±0.41) mm.The rate of type and diameter of mural coronary artery had significant differences between two groups (P<0.05), while other data had no significant differences (P>0.05).Conclusion The CTA features of asymptomatic myocardial bridge are mostly superficial type.The diameter of mural coronary artery on the end systolic is a factor to judge the rate on the occurrence of clinical symptom.
