Abstract:
Objective To compare the value of the coronary angiography by dual source CT (DSCT)and the transthoracic echo-cardiography (TTE)in the diagnosis of patent foramen ovale(PFO).Methods Recruiting total 476 cases,those who had both of the coronary angiography by DSCT and TTE within 24 hours,collecting the diagnosis cases number and related data for analysis.Results There were 101 out of 476 cases(21.2%)that were diagnosed PFO by coronary angiography DSCT.There were 68 out of 101 cases (67.3%)combined with left right shunt in atrium and there were 33 of 101 cases (32.7%)had no findings in diagnosis of left right shunt(LRS).There were also 5 out of 101 cases combined with atrial septal aneurysm.Meanwhile,there were 71 out of 476 cases (14.94%)that were diagnosed PFO by TTE.5 out of them were combined with atrial septal aneurysm.The diagnosis rate of PFO by TTE combined with CDFI was less than coronary angiography DSCT(P<0.05).The diameter of the opening in PFO measured by DSCT and TTE were (2.55 ±1.62)mm and (2.71±1.41)mm respectively,which was no statistically significant (P>0.05).Con-clusion Coronary angiography DSCT is better than TEE in diagnosis rate and anatomical structures displing in PFO.
