Abstract:
Objective To investigate the value of echocardiography in the diagnosis of interrupted aortic arch (IAA). Methods Forty-three children that diagnosed as IAA by transthoracic echocardiography (TTE) were reviewed. The results of CTA (CT Angiography) and operation also were compared. Results Among the 43 children, 41 was admitted as IAA by operation and 2 were diagnosed as coarctation of aorta. According to the type of IAA, 25 cases were diagnosed as type A, 13 cases were diagnosed as type B, 3 cases were diagnosed as type C. Thirty-ifve cases were diagnosed by TTE correctly, 3 cases were misdiagnosed by TTE, 4 cases were suspected as IAA by TTE and ifnally conifrmed by operation. The accuracy rate was 81%(35/43). Among the 35 deifnite diagnosed cases, corrected typing cases were 30, the accuracy rate was 86%(30/35). The accuracy rate of type A, B, C were 96%(23/24), 64%(7/11) and 0. According to the results of CTA, 40 cases were diagnosed correctly, 1 case was misdiagnosed. The accuracy rate was 98%(40/41). Among the deifnite diagnosed cases, corrected typing rate was the same with operation result. Conclusions TTE is the ifrst choice for the detection of IAA. During TTE, in case the indistinct display of aortic arch, CTA should be used to improve the accuracy rate of IAA.
