RESUMO
Objective:To comparative Research with MSCT and CAG in the myocardial bridge-wall diagnostic coronary. Methods: Selected 93 patients for the study in January 2011 to the end of December 2013,MB-MCA patients diagnosed in Beijing North Hospital, all patients underwent catheter coronary angiography (CAG) and 64-slice spiral CT (MSCT), comparison of the diagnostic accuracy of the two inspection methods, and the results of the correlation analysis, results processing and analysis using statistical software SPSS17.0. Results:MSCT and CAG were two examination methods in the diagnosis of superficial and deep type MB-MCA, with a high degree of consistency in the diagnosis of MB-MCA average length, average depth comparison with statistical significance(t=3.021, t=3.758;P<0.05), there was not statistically significant comparison in the narrow detection rate. Conclusion:MSCT as a novel, non-invasive means of MB-MCA examination, the diagnosis results are reliable, accurate and capable of providing a richer diagnostic information for clinicians, clinician and patient can be widely applied.
RESUMO
Objective: To discuss the morphologic diagnosis value of CTA technical on myocardial bridge-wall coronary artery. Methods: Three hundred and seventy seven patients suspected MB-MCA and with CTA and CAG inspection voluntary in cardiology clinic or hospital were analyzed, and the occurrence of type MB-MCA and MCA MB length and degree of stenosis were recorded, the results were analyzed using SPSS17.0 statistical software. Results:103 cases of 377 were diagnosed as final MB-MCA, and there were 110 MB-MCA in total. CTA and CAG checked by means of two kinds of shallow and deep in the model type MB-MCA diagnostic analysis were compared through Kappa analysis, the Kappa value were 0.803 and 1.000. Two methods had a good consistency in the diagnosis of MB-MCA;There were statistically significant in CTA and CAG two kinds of examination methods in the diagnosis of superficial in type (t=-5.149)and deep in the type MB (t=-2.457, P=0.024)(P<0.05). Conclusion:The multi-slice spiral CT angiography CTA technology has good consistency with CAG in MB-MCA diagnosis, can achieve complementary advantages, can combine their respective advantages MB-MCA to improve the diagnostic accuracy for clinical richer diagnostic information.
