Objectives: To analyze the clinical characteristics, echocardiographic features, and prognosis of fetuses based on three groups of cardiac manifestations associated with maternal anti-Ro and anti-La antibodies in China. This study included three groups: the isolated-arrhythmia, isolated-endocardial fibroelastosis (EFE), and mixed groups. Methods: We prospectively evaluated 36 fetuses with cardiac manifestations due to maternal anti-Ro and anti-La antibodies from our center between 2016 and 2020 in China. Clinical and echocardiographic data were collected. Results: There were 13 patients (36%) in the isolated-arrhythmia group, eight (22%) in the isolated-EFE group, and 15 (42%) in the mixed group. All patients in the isolated-EFE group presented with mild EFE. Severe EFE was identified in four patients (27%) in the mixed group. Atrioventricular block (AVB) was more common in the isolated-arrhythmia group (13, 100%) than in the mixed group (6, 40%; p = 0.001). Moderate-severe mitral regurgitation (p = 0.006), dilated cardiomyopathy (DCM, p = 0.017), and low cardiovascular profile scores (p = 0.013) were more common in the mixed group than in the other two groups. Twenty-one mothers decided to terminate the pregnancy and 15 fetuses were born with regular perinatal treatment. They all survived at 1 year of age. One patient in the isolated-arrhythmia group and two in the mixed group required a pacemaker due to third-degree AVB or atrioventricular junctional rhythm. Five patients in the isolated-EFE group and five in the mixed group had no DCM or heart failure and the location of mild EFE was significantly reduced. Conclusion: Fetal cardiac manifestations due to maternal anti-Ro and anti-La antibodies can be divided into three groups, i.e., the isolated-arrhythmia, isolated-EFE, and mixed groups. AVB usually occurs in the isolated-arrhythmia group. Severe EFE, moderate-severe mitral regurgitation, and DCM mainly appear in the mixed group. Location of mild EFE significantly reduces after birth and the outcome of fetuses with mild EFE depends on the presence of arrhythmia and its subtypes.
RESUMO
OBJECTIVE: To explore whether the post-left atrium space (PLAS) ratio would be useful for prenatal diagnosis of total anomalous pulmonary venous connection (TAPVC) using echocardiography and artificial intelligence. METHODS: We retrospectively included 642 frames of four-chamber views from 319 fetuses (32 with TAPVC and 287 without TAPVC) in end-systolic and end-diastolic periods with multiple apex directions. The average gestational age was 25.6 ± 2.7 weeks. No other cardiac or extracardiac malformations were observed. The dataset was divided into a training set (n = 540; 48 with TAPVC and 492 without TAPVC) and test set (n = 102; 20 with TAPVC and 82 without TAPVC). The PLAS ratio was defined as the ratio of the epicardium-descending aortic distance to the center of the heart-descending aortic distance. Supervised learning was used in DeepLabv3+, FastFCN, PSPNet, and DenseASPP segmentation models. The area under the curve (AUC) was used on the test set. RESULTS: Expert annotations showed that this ratio was not related to the period or apex direction. It was higher in the TAPVC group than in the control group detected by the expert and the four models. The AUC of expert annotations, DeepLabv3+, FastFCN, PSPNet, and DenseASPP were 0.977, 0.941, 0.925, 0.856, and 0.887, respectively. CONCLUSION: Segmentation models achieve good diagnostic accuracy for TAPVC based on the PLAS ratio.

BACKGROUND: Isolated aortic brachiocephalic artery (IABA) is a rare congenital aortic arch anomaly. It is difficult to diagnose IABA prenatally and the prevalence in the prenatal population is unknown. PURPOSE: To evaluate the echocardiographic characteristics and associations in fetuses with IABA. MATERIAL AND METHODS: We retrospectively analyzed all cases of prenatal diagnosis of IABA from January 2012 to November 2020 and reviewed the follow-up results. Copy Number Variation Sequencing (CNV-Seq) was performed using the biological specimens of the of the fetuses and family members. RESULTS: Ten cases (10/45652, 0.022%) of IABA were identified in our center. The prevalence of the cases with isolated left subclavian artery (ILSCA) in the right aortic arch (RAA) population was 0.98% (6/613). The ILSCA was the most common isolated arch branch. All the isolated branches were on the opposite side of aortic arch in all the cases. The "ice stick" sign in the coronal section could be seen in most cases of IABA. Of the 10 cases, 8 (8/10, 80%) were associated with tetralogy of Fallot (TOF). Two cases of IABA were combined with 22q11.2 deletion syndrome. CONCLUSION: IABA is a rare aortic anomaly. ILSCA was the most common isolated arch branch and TOF was the most common associated intra-cardiac anomaly. The "ice stick" sign in the coronal section could indicate a diagnosis of the IABA.

BACKGROUND: Congenital atrial appendage aneurysm (AAA) is a rare malformation which can coexist with potentially lethal complications. We aimed to summary echocardiographic characteristics and prognosis of fetal AAA. METHODS: We retrospectively analyzed the echocardiographic data of 17 fetuses with AAAï¼and their outcomes or pathological reports were also collected. RESULTS: Eight fetuses with left AAA (LAAA) and 9 fetuses with right AAA (RAAA) were identified. Five fetuses were diagnosed with other cardiac defects. Two fetuses with RAAA presented with arrhythmias, including atrial premature beats (n = 1) and bradyarrhythmia (n = 1). LAAA could be detected by four-chamber view (50.0%) and short-axis view (100.0%). RAAA could be detected by four-chamber view (100.0%), and view of right ventricular inflow tract (33.3%). There were three cases with mild pericardial effusion. Three cases with complex cardiac defects were selectively terminated, with confirmation of LAAA by autopsy in one case. Fourteen fetuses were born. After following 2 (range, 1-5) years, the AAA disappeared in one case with LAAA and two cases with RAAA. While, 11 cases were still diagnosed with AAA. Atrial premature beats with RAAA, which appeared in prenatal period, still persisted after birth. CONCLUSION: Congenital AAA is a rare abnormality in utero. The short-axis view and the four-chamber view were the most useful views to detect fetal AAA. Fetal AAA may disappear in childhood. Atrial tachyarrhythmias in utero may exist persistently after birth. Patients with AAA should be followed up closely and appropriate intervention should be taken when complications appeared.

Berry syndrome is a rare congenital cardiac malformation. We describe 4 cases of Berry syndrome diagnosed by fetal echocardiography. Based on our experience, the three-vessel view is important for diagnosing the aortopulmonary window and aortic origin of the right pulmonary artery. Furthermore, the true cross-sectional and sagittal views obtained by continuously scanning from the three-vessel-trachea view to the long-axis view of the aortic arch are required to image the interruption or coarctation of the aortic arch. An early and accurate prenatal diagnosis of Berry syndrome is feasible and helps to improve patient outcomes.

OBJECTIVES: Intramyocardial dissecting hematoma (IDH) after acute myocardial infarction (MI) is a rare form of subacute cardiac rupture and hence management uncertainties. The objective of this study was to describe the clinical course of a small series of IDH patients and to review the available evidence for managing similar cases. METHODS: Eight IDH patients from our center had echocardiographic, coronary angiographic and clinical outcome data reviewed. PubMed was also searched for IDH following MI. Cases were divided into three groups and compared according to the dissection location. RESULTS: In our 8 patients, 3 had septal, 1 right ventricular (RV), and 4 left ventricular (LV) dissection. Five were medically treated and 3 surgically repaired. Reviewing the literature revealed 68 IDH patients, of mean age 66 ± 10 years, 43 males. The percentage of IDH involving the LV free wall, septal, and RV free wall were 47%, 26.5%, and 26.5%, respectively. In the cohort as a whole, mortality was not different between surgically and medically treated patients (33.3% vs. 54.3%, P = 0.08), neither based on the IDH location (P = 0.49). While surgical and medical treatment of the LV free wall (20.0% vs. 40.9%, P = 0.25) and septal (46.2% vs. 60.0%, P = 0.60) were not different, surgical repair of RV free wall had significantly better survival (30.0% vs. 87.5%, P = 0.015). The LVEF (P = 0.82), mitral regurgitation (P = 0.49) failed to predict mortality. CONCLUSION: While survival following medical and surgical treatment of LV IDH is not different, patients with RV free wall dissection benefit significantly from surgical repair.

The aim of this study was to determine the diagnostic value of an ROC curve of the antepartum foramen ovale (AFO) size and the ratio of FO size to aorta (AO) size (FO/AO) for the prediction of puerperal atrial septal defect in different gestational weeks (DGWs). A total of 958 cases were divided into five groups according to number of gestational weeks. Comparisons of FO size, AO size and FO/AO were determined by variance analysis. The correlations between FO size, AO size and gestational age were determined using regression analysis and comparisons between atrial septal defect (ASD) diagnosed in DGWs and normal cardiac FO size and FO/AO were analyzed by t-test. ROC curve analysis was used for FO size and FO/AO to predict the demarcation point of puerperal ASD (pASD). The differences between FO size and AO size in the five groups at DGWs were statistically significant (P=0.000). The sizes of FO and AO increased with gestational age. The differences among pASD, normal cardiac FO size and FO/AO were statistically significant (P=0.000). FO size in the five DGW groups (18-22, 23-26, 27-30, 31-34 and 35-40 weeks) was able to predict the demarcation points of pASD, which were 5.02, 5.15, 6.55, 8.55 and 7.90 mm, respectively. The prediction of pASD with AFO size and FO/AO was accurate and may provide reliable reference values in the clinic.
RESUMO
We report the findings of three-dimensional (3D) transesophageal echocardiography (TEE) in a patient with a parachute mitral valve (MV) accompanied by aortic valve (AV) malformation. The results indicated an enhanced echo in MV anterior leaves, incrassate, and shortened subvalvular chordae tendineae, and posteromedial papillary muscle that had echo reinforcement, calcification, retroposition, and a significant decrease compared with anterolateral papillary muscle. In addition, the anterolateral papillary muscle was huge, with the bilateral papillary muscles fused partly, and the posterior subvalvular chordae tendineae incrassate, shortened, and attached parachute-like to the anterolateral papillary muscle. The MV appeared dome-shaped for the open limit in diastole with an MV area of 1.6 cm. Moreover, the left ventricle increased in size and the bicuspid AV was malformed. Continuous wave Doppler angiograph showed that the flow rate increased to 398 cm/seconds at the AV orifice area. A 3D form of the MV structure was observed from the left ventricle using 3D-TEE inspection. The anterolateral papillary muscle was fused with its posteromedial homologue. The chordae tendineae was attached to the anterolateral papillary with the parachute-like structure, indicating dome movement.
