This study was to explore the application and effect of three-dimensional (3D) images of the esophagus in the treatment of atrial septal defect (ASD) combined with tricuspid regurgitation (TR) surgery under the processing of marching cubes (MC) image reconstruction algorithm. The MC image reconstruction algorithm was improved as the optimized MC image reconstruction algorithm. 100 patients who had successfully undergone the ASD combined with TR surgery in the hospital from January 2017 to December 2019 were selected as the research objects and grouped based on size of the defect. The preoperative and postoperative conditions of the patients were analyzed with the MC image reconstruction algorithm. Compared with the traditional MC image algorithm, the optimized MC was advanced with less running time and fewer fixed points ( P < 0.05 ). There were significant differences in TR of all ASD patients after the surgery ( P < 0.05 ), and the TR of all patients showed obvious declines from the 1st day to 30th day after surgery and gradually stabilized from the 3rd month to the 6th month after surgery. Compared with patients with normal pulmonary artery pressure, the amount of TR in patients with elevated pulmonary artery pressure increased significantly, and the difference was statistically significant ( P < 0.05 ). In addition, the improvement of TR after occlusion was correlated with the preoperative ASD of the patient. The optimized MC algorithm had been improved greatly in the number of fixed points and running time. The analysis using the optimized MC algorithm showed that ASD patients generally suffered different degrees of TR, TR increased with the increase of the defect, and good effect could be achieved in surgery of all kinds of ASD patients.

Background and Objectives. Pulmonary arterial hypertension (PAH) pathomechanism involves an increased plasma level of endothelin-1 and a reduced plasma level of prostacyclin and nitric oxide. Whether similar mechanisms prevail in PAH associated with atrial septal defect (ASD) is unclear. This study aimed to investigate the relationship of endothelin-1, prostacyclin, and nitric oxide with PAH in uncorrected ASD in Indonesian population. Methods. The study design was cross-sectional. The subjects were adult uncorrected secundum ASD with PAH. Pulmonary artery pressure was measured with right heart catheterization. Pulmonary venous blood was obtained during catheterization for measuring endothelin-1, prostacyclin, and nitric oxide. Correlation tests were performed to determine any association between biomarkers and mean pulmonary artery pressure (mPAP). The levels of biomarkers were compared based on the severity of PAH. Statistical significance was determined at p<0.05. Results. Forty-four subjects were enrolled in this study. Endothelin-1 level and mPAP had significant moderate positive correlation (r = 0.423 and p value = 0.004). However, no significant correlation was observed between prostacyclin, nitric oxide levels, and mPAP. The pattern of endothelin-1, prostacyclin, and nitric oxide was distinctive. Levels of endothelin-1 were incrementally increased from mild, moderate, to severe PAH. The levels of prostacyclin and nitric oxide had similar pattern in association with the severity of PAH, which was increased in mild-to-moderate PAH but decreased in severe PAH. Conclusions. There was a distinctive pattern of endothelin-1, prostacyclin, and nitric oxide based on severity of PAH in adult uncorrected ASD. Significant correlations existed between endothelin-1 and the severity of PAH and mPAP.

Uncorrected atrial septal defect undergoes right ventricle chronic volume overload which may lead to pulmonary hypertension and Eisenmenger Syndrome. The soluble suppression of tumorigenicity-2 is a left ventricle strain biomarker; however, its role in right ventricle strain is unclear. This study aimed to investigate the implication of serum soluble suppression of tumorigenicity-2 in adult uncorrected atrial septal defect. This was a cross-sectional study. We enrolled 81 adult uncorrected secundum atrial septal defect patients. Clinical and hemodynamic data were collected. Serum samples were withdrawn from the pulmonary artery during right heart catheterization. Serum soluble suppression of tumorigenicity-2 and NT-proBNP levels were measured. Subjects were divided into three groups based on clinical and hemodynamic severity. The correlation of soluble suppression of tumorigenicity-2 with patients' data and comparison among groups were analyzed. A p value <0.05 was considered statistically significant. Results showed that, there were significant correlations between serum soluble suppression of tumorigenicity-2 and mean pulmonary artery pressure ( r = 0.203, p = 0.035) and right ventricle end-diastolic diameter ( r = 0.203, p <0.05). Median serum soluble suppression of tumorigenicity-2 level was incrementally increased from group I (atrial septal defect and no-pulmonary hypertension), group II (left-to-right atrial septal defect and pulmonary hypertension), to group III (Eisenmenger Syndrome): (17.4 ng/mL, 21.8 ng/mL, and 29.4 ng/mL, respectively). A post-hoc analysis showed that serum soluble suppression of tumorigenicity-2 level was significantly different between groups I and III ( p = 0.01). Serum N terminal pro brain natriuretic peptide (NT-proBNP) level was consistently associated with worse clinical and hemodynamic parameters. No correlation was found between serum soluble suppression of tumorigenicity-2 and NT-proBNP level. In conclusion, serum soluble suppression of tumorigenicity-2 level had significant positive correlation with mean pulmonary artery pressure and right ventricle end-diastolic diameter in uncorrected secundum atrial septal defect patients. Higher serum soluble suppression of tumorigenicity-2 level was associated with the presence of pulmonary hypertension and Eisenmenger Syndrome in uncorrected secundum atrial septal defect patients.

Abstract Pulmonary hypertension is not the only cause of arterial desaturation in patients with atrial septal defect. Arterial desaturation can also occur with normal pulmonary artery pressure making it mandatory to understand the mechanism to avoid erroneous diagnosis. In this report, for the first time, we demonstrate atrial flutter as the cause of arterial desaturation in a patient with large atrial septal defect despite normal pulmonary artery pressure, which was normalised following successful radiofrequency ablation.

Pulmonary hypertension is a common complication of congenital heart disease due to systemic – pulmonary circulation shunt which if left uncorrected leads to increased pulmonary artery pressure, vascular remodeling and further increase of pulmonary vascular resistance. Percutaneous closure of the defect interrupts this shunt thus reducing right heart and pulmonary circulation load and pulmonary artery pressure. In this paper we present two cases of percutaneous secundum atrial septal defect closure complicated by pulmonary hypertension along with echocardiographic evaluation of cardiopulmonary hemodynamic changes before and shortly after device closure. Forty years old and thirty three years old females presented to our clinics with classical symptoms of atrial septal defects, assessment revealed TVG of 37 mmHg and 30 mmHg,shortly after the procedure patient was re-evaluated and revealed TVG of 39 mmHg and 23 mmHg respectively. From these cases we conclude that changes in pulmonary artery pressure is not constantly found after device closure. However both patients display improvements in functional capabilities.
