Background: Atrial septal defect and its closure can lead to changes in the right and left cardiac cavities' function and size. In this study, Z-scores of the cardiac chambers and the heart function were assessed, and the important complications were mentioned. Methods: This interventional cross-sectional study was done on patients who had atrial septal defect closure aged younger than 18 years. All patients were recruited for transthoracic echocardiography. About half of the patients were randomly selected. The information of angiography and its side effects belong to all patients, but the echocardiographic parameters and Z-scores belong only to the selected group. Results: A total of 370 patients underwent the atrial septal defect closure, of whom 150 patients participated in the study. The patients' average age and weight were 9.25 ± 3.44 years and 15.12 ± 11.83 kg, respectively, and the mean follow-up time was 2.56 years. Z-scores of the interventricular septal dimension in diastole, the left ventricular posterior wall dimension in diastole, the left ventricular internal dimension in systole, and Z-scores of the size of the right atrium, right ventricle, pulmonary valve annulus, and the main pulmonary artery were more than Z-scores of the normal population. Furthermore, Z-scores of the E/A and the Eat/Aat of the tricuspid valve were less than their peers. Besides, the correlation between Z-scores and the atrial septal defect size and weight of the patients was assessed, which was statistically significant, and patients who underwent atrial special defect closure at the age of fewer than three years and less than 15 kg had more normal cardiac Z-scores. Conclusions: Z-scores of the cardiac chambers and pulmonary artery were more than normal after successful closure of the atrial septal defect in the mid-term follow-up.

Abstract Background Unilateral pulmonary artery discontinuity is a rare malformation that is associated with other intracardiac abnormalities. Cases accompanied by other cardiac abnormalities are often missed on prenatal echocardiography. The prenatal diagnosis of isolated unilateral pulmonary artery discontinuity can also be delayed. However, undiagnosed this malformation would have an effect on further prognosis. We report our case of a prenatal diagnosis of pulmonary atresia with ventricular septal defect and left pulmonary artery discontinuity. Case presentation A 33-year-old Asian woman visited our institution at 24 weeks of gestation because of suspected fetal congenital heart disease. Fetal echocardiography revealed a small atretic main pulmonary artery giving rise to the right pulmonary artery without bifurcation and the left pulmonary artery arising from the ductus arteriosus originating from the left subclavian artery. The neonate was delivered by cesarean section at 376/7 weeks of gestation. Postnatal echocardiography and multidetector computed tomography showed a right aortic arch, with the small right pulmonary artery originating from the atretic main pulmonary artery and the left pulmonary artery originating from the left subclavian artery. Patency of the ductus arteriosus from the left subclavian artery was maintained with prostaglandin E1. Right ventricular outflow tract reconstruction and pulmonary angioplasty with Gore-Tex graft patch was performed 25th day after birth. Unfortunately, the neonate died because of right heart failure 8 days postoperation. Conclusion There is a possibility that both pulmonary arteries do not arise from the same great artery (main pulmonary artery or common arterial trunk). Therefore, clinicians should check the origin of both pulmonary arteries.

Background: Secundum atrial septal defect (SASD) closure is contraindicated in the presence of severe pulmonary artery hypertension (PAH). However, there is no consensus on the threshold of severe PAH, in terms of mean pulmonary artery pressure (mPAP), which would contraindicate for defect closure surgery in adults. Furthermore, PAH can persist, or even increase in severity, after the closure. The aim of this study was to produce a predictive model correlating mPAP in adult SASD patients with PAH after defect closure surgery. Methods: Between January 2014 and March 2017, 29 consecutive adult SASD patients who had PAH and underwent defect closure surgery were included in the study. Age, right atrium (RA) dimension, right ventricle (RV) dimension, and mPAP before surgery were analyzed using multiple regression to produce the model.Results: Multiple regression produced the following model: mPAP prediction = (0.24)(Age) + (0.06)(mPAP before surgery) + (0.17)(RA dimension) + (0.47)(RV dimension) – 13.79 (P = .0008). The mPAP prediction was compared to mPAP of the patients six to nine months after surgery, and showed no significant difference (P = .9562). Conclusion: In adult SASD patients with PAH, our model can significantly predict the mPAP after the closure. If the predicted mPAP is within its normal range, the closure is indicated.

The objective of this study was to compare the effects of different shunt diameters and pulmonary artery (PA) stenosis grades on the hemodynamics of central shunts to determine an optimal surgical plan and improve the long-term outcomes of the operation. A 3D anatomical model was reconstructed based on the patient’s clinical CT data. 3D computational fluid dynamics models were built with varying degrees of stenosis (the stenosis ratio α was represented by the ratio of blood flow through the main pulmonary artery to cardiac output, ranging from 0 to 30%; the smaller the value of α, the more severe the pulmonary artery stenosis) and varying shunt diameters (3, 3.5, 4, 4.5, and 5 mm). Our results show that the asymmetry of pulmonary artery flow increased with increasing shunt diameter and α, which will be more conducive to the development of the left pulmonary artery. Additionally, the pulmonary-to-systemic flow ratio (QP/QS) increases with the shunt diameter and α, and all the values exceed 1. When the shunt diameter is 3 mm and α = 0%, QP/QS reaches the minimum value of 1.01, and the oxygen delivery reaches the maximum value of 205.19 ml/min. However, increasing shunt diameter and α is beneficial to reduced power loss and smoother PA flow. In short, for patients with severe PA stenosis (α is small), a larger-diameter shunt may be preferred. Conversely, when the degree of PA stenosis is moderate, a smaller shunt diameter can be considered.
