Abstract:
Objective To investigate the value of prenatal ultrasound observation of subaortic conical connection in the diagnosis of complete transposition of great arteries(TGA).Methods Echocardiography findings of 22 cases with complete TGA confirmed by autopsy were retrospectively analyzed and summarized.Results All cases were shown subaortic conical connection on two-dimensional echocardiography,the two great arteries were parallel in 18 cases on left ventricular long-axis view,the character of normal right ventricular outflow tract surrounding the aortic root disappeared in 17 cases.There were 13 cases with ventricular septal defect and 2 cases with left ventricular outflow tract obstruction.Aorta and pulmonary artery were shown in right anterior and left posterior position among 20 cases,and in anterior and posterior position in 2 cases.Conclusions Prenatal ultrasound observation of subaortic conical connection is of great value in the diagnosis of complete TGA.
