“…Compared with the two-dimensional digital image, the three-dimensional model could more directly and comprehensively present the spatial information of the object, so the reconstructed three-dimensional model of the blood vessel was conductive to diagnosis of the disease better. Manuel et al (2017) showed in the study that most adult ASD patients had different degrees of TR, and patients with moderate to severe TR accounted for about 20% of the total number [14]. In this experiment, there were 12 patients with the amount of TR above 25 mL before the surgery, and there were no patients with the amount of TR higher than 50 mL.…”

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.

“…There are reports of a floppy eustachian valve directing the flow from the inferior caval vein to the left atrium. [1][2][3] This has been described as early as in 1976. 10 The very first description of atrial septal defects with cyanosis dates from 1949, where Selzer and Lewis postulate functional drainage of systemic venous blood into the left atrium.…”

“…In very few case reports, the eustachian valve remains functional and even after birth divides systemic venous blood towards the left atrium. [1][2][3] Anatomical connections of systemic veins to the left atrium are rare. They lead to different degrees of cyanosis dependent on the amount of systemic venous blood mixing with the pulmonary venous retour.…”

Cyanosis due to an isolated atrial septal defect: case report and review of the literature

2020

Isolated atrial defects usually lead to left-to-right shunt and right ventricular volume load. Descriptions of cyanosis with this congenital heart defect are rare. We describe a rare case of inferior caval vein flow directed through an atrial septal defect in the fossa ovalis leading to severe cyanosis, but without any additional intracardiac anatomical abnormalities. The baby with clinical features of Marfan’s syndrome had an eventration of the right-sided diaphragm. Surgical closure of the defect resolved the cyanosis, but the child died 10 weeks later of severe valvar dysfunction, related to Marfan’s syndrome. Mechanisms of cyanosis in patients with atrial septal defects are discussed. Echocardiographic bubble studies both from the lower and upper half of the body may help to clarify the mechanism of an otherwise unexplained cyanosis.

Atrial septal defect with right-to-left shunt in the absence of pulmonary hypertension

Abstract: We describe the case of a 27-year-old gentleman who developed late-onset clubbing and cyanosis. Transoesophageal echocardiography revealed a 27-mm ostium secundum atrial septal defect and a large, floppy Eustachian valve directing right atrial blood to the left side of the heart.
