Objective To explore the value of three-vessel and trachea(3VT) view plus aortic arch coronal section in ultrasonic diagnosis and classification of fetal right aortic arch(RAA).Methods Echocardiography data and follow-up results of 44 fetuses with RAA were retrospectively analyzed.Sonographic features on 3VT view and aortic arch coronal section were summarized.Results Among 44 fetuses with RAA,27 cases(61.36%) were RAA with aberrant left subclavian artery(ALSA) and the left ductus arteriosus(LDA) connecting the ALSA and U-shaped vascular ring was formed;17 cases(38.64%) were mirror right aortic arch(MRAA).Among 17 cases with MRAA,3 cases were with LDA connecting the descending aorta(DAO) and U-shaped vascular ring was formed;1 case was with LDA connecting the left innominate artery(LINA),8 cases were with absent ductus arteriosus(ADA),5 case were with right ductus arteriosus(RDA),no vascular ring was formed.Parts of MRAA were combined with other complex intracardiac abnormalities.RAA-ALSA-LDA were rarely combined with intracardiac abnormalities.Conclusions 3VT view is simple and intuitive for diagnosing RAA.Aortic arch coronal section has great clinical value in determining the concrete type of RAA.

Objective To summarize the prenatal ultrasonographic characteristics of anomalous origin of one pulmonary artery from the aorta( AOPA ) ,and describe the diagnostic and clinical outcomes of fetal AOPA . Methods Echocardiographic characteristics of 3 fetuses with AOPA were reviewed . The ultrasonographic features were comparatively analyzed with postpartum autopsy findings . The relevant literature were reviewed and the experience of prenatal diagnosis of AOPA were summarized . Results In 3 cases with AOPA ,2 cases were the proximal type and anomalous origin of right pulmonary artery from the aorta ,of them ,one was accompanied with coarctation of the aorta , the other was accompanied with aortopulmonary window . One case was the distal type and anomalous origin of left pulmonary artery from the left innominate aorta ,it was only associated with mirror right aortic arch and right ductus arteriosus . Ultrasound characteristics were no bifurcation in distal pulmonary artery ,main trunk of pulmonary artery extends directly to one branch ,the other branch originated from the ascending aorta or left innominate artery . Three cases were confirmed by postpartum autopsy . Conclusions There are some characteristic signs on ultrasonic features of AOPA . Prenatal ultrasound has important value for diagnosis of AOPA .

Objective:
This study used cardiac magnetic resonance imaging (MRI) to compare the characteristics of left ventricular remodeling in patients with primary aldosteronism (PA) with those of patients with essential hypertension (EH) and healthy controls (HCs).
Materials and Methods:
This prospective study enrolled 35 patients with PA, in addition to 35 age- and sex-matched patients with EH, and 35 age- and sex-matched HCs, all of whom underwent comprehensive clinical and cardiac MRI examinations. The analysis of variance was used to detect the differences in the characteristics of left ventricular remodeling among the three groups. Univariable and multivariable linear regression analyses were used to determine the relationships between left ventricular remodeling and the physiological variables.
Results:
The left ventricular end-diastolic volume index (EDVi) (mean ± standard deviation [SD]: 85.1 ± 13.0 mL/m2 for PA, 75.9 ± 14.3 mL/m2 for EH, and 77.3 ± 12.8 mL/m2 for HC; p = 0.010), left ventricular end-systolic volume index (ESVi) (mean ± SD: 35.2 ± 9.8 mL/m2 for PA, 30.7 ± 8.1 mL/m2 for EH, and 29.5 ± 7.0 mL/m2 for HC; p = 0.013), left ventricular mass index (mean ± SD: 65.8 ± 16.5 g/m2 for PA, 56.9 ± 12.1 g/m2 for EH, and 44.1 ± 8.9 g/m2 for HC; p < 0.001), and native T1 (mean ± SD: 1224 ± 39 ms for PA, 1201 ± 47 ms for EH, and 1200 ± 44 ms for HC; p = 0.041) values were higher in the PA group compared to the EH and HC groups. Multivariable linear regression demonstrated that log (plasma aldosteroneto-renin ratio) was independently correlated with EDVi and ESVi. Plasma aldosterone was independently correlated with native T1.
Conclusion
Patients with PA showed a greater degree of ventricular hypertrophy and enlargement, as well as myocardial fibrosis, compared to those with EH. Cardiac MRI T1 mapping can detect left ventricular myocardial fibrosis in patients with PA.

【Objective】 To compare the clinical value of magnetic-controlled capsule endoscopy (MCE) and traditional capsule endoscopy (CE) in the diagnosis of intestinal diseases in hospitalized patients. 【Methods】 A single-center retrospective study was conducted in 263 inpatients who underwent MCE and CE in The First Affiliated Hospital of Xi’an Jiaotong University from March 2016 to March 2020. The information included the patients’ general data, chief complaints, and results of capsule endoscopic examination. 【Results】 ① The overall detection rate in small intestinal diseases was 74.45% in MCE group and 73.81% in CE group, respectively (P=0.905). The three most common diseases in the two groups were erosive/ulcerative lesions, vascular lesions, and lymphangiectasia. ② The endoscopic auxiliary rate was significantly lower in MCE group than in CE group (0% vs. 9.49%, P<0.001). ③ There was no significant difference in the rate of intestinal incompletion between the two groups (7.94% vs. 13.87%, P=0.185). 【Conclusion】 MCE is similar to CE in the diagnostic value for intestinal diseases. Currently, it can be used as one of the methods of small intestinal examination, but this needs to be supported by more multicenter and sizable simple studies.
