Project description:BackgroundSeptal malalignment is related to erosion and device embolization in transcatheter closure of atrial septal defect (ASD), but limited information is available.ObjectivesThis study aimed to assess clinical significance of septal malalignment and to determine appropriate evaluation of ASD diameter, including the selection of device size.MethodsFour hundred and seventeen patients with ASD who underwent transcatheter closure were enrolled. Septal malalignment was defined as separation between the septum primum and the septum secundum on transesophageal echocardiography.ResultsOne hundred and eighty-four patients had septal malalignment. The frequency of septal malalignment increased with age reaching around 50% in adult patients. Septal malalignment was related to aortic rim deficiency. The distance of separation between the septum primum and the septum secundum was 5 ± 2 mm (range, 1-11 mm). In patients with septal malalignment, the ASD diameter measured at the septum primum was 19 ± 6 mm, while the ASD diameter measured at the septum secundum was 16 ± 6 mm. There was a difference of 4 ± 2 mm (range, 0-8 mm) between the ASD diameter measured at the septum primum and that measured at the septum secundum. For transcatheter closure, the Amplatzer Septal Occluder device size 2-3 mm larger and the Occlutech Figulla Flex II device size 4-7 mm larger than the ASD diameter measured at the septum primum were frequently used. During the study period, erosion or device embolization did not occur in all of the patients.ConclusionsSeptal malalignment is highly prevalent in adult patients with aortic rim deficiency. The measurement of ASD diameter at the septum primum can be valuable for the selection of device size in patients with septal malalignment.

Project description:To date, no significant association has been reported between atrial septal defects (ASD) and cardiac myxomas. This study reports a 56-year-old woman with cardiac myxoma following transcatheter closure of ASD. She presented with a 3-month history of recurrent dizziness, vertigo, palpitations, and generalized weakness after undergoing ASD occlusion a year earlier. Echocardiography and cardiac computed tomography scans identified a large, mobile mass (7.2 cm × 2.8 cm) in the left atrium, protruding through the mitral valve. The patient underwent median sternotomy and pericardiotomy, and the histopathological examination confirmed the diagnosis of atrial myxoma. The current case illustrates the challenges in determining whether an atrial mass is a benign myxoma or a dangerous thrombus. While there is no definitive link between the implantation of an ASD closure device and the formation of a myxoma, the emergence of this tumor is a potential occurrence.

Project description:A 92-year-old man was referred to our hospital with decompensated heart failure. He was treated with diuretics and inotropic agents, but the clinical response was unsatisfactory. Echocardiography incidentally revealed an atrial septal defect (ASD) with a significant left-to-right shunt and pulmonary-to-systemic-blood-flow ratio of 2.36. Because the ASD was considered to be the primary cause of his treatment-resistant heart failure, the patient underwent transcatheter ASD closure. Shortly after shunt closure, his hemodynamics significantly improved, and he was discharged nine days later. This is an extremely rare case of a nonagenarian who showed an excellent clinical course after transcatheter ASD closure.

Project description:Cor triatriatum dexter is an extremely rare congenital heart defect and cause of hypoxia in adults. We describe a case of cor triatriatum dexter discovered incidentally due to an iatrogenic atrial septal defect. The cor triatriatum dexter resolved with balloon dilation - a novel technique to manage this rare clinical condition. <Learning objective: Management of cor triatriatum dexter, an exceptionally rare diagnosis, has often been thought to be surgical. However, percutaneous intervention may be considered in select clinical situations.>.

Project description:Atrial septal defect (ASD) and patent ductus arteriosus (PDA) are both common congenital heart diseases, but the combination of these two cardiac defects is extremely rare, and the therapeutic strategy is controversial. We treated an adult patient with combined ASD and PDA, and safely attained a successful outcome with two-stage transcatheter closure, which is PDA closure preceding ASD closure, to prevent serious complications. Transcatheter closure of one of the defects is now widely accepted as an alternative to surgical closure. In addition, adults with both ASD and PDA are better suited for transcatheter closure than surgical closure. One of the reasons is the difficulty to ligate the ductus arteriosus of an adult patient due to its friability and calcification. Meanwhile, simultaneous combined transcatheter closure of ASD and PDA can result in serious complications, such as thrombocytopenia and haemolysis, whose mechanism is considered to be the destruction of platelets and red blood cells by the residual shunt through implanted devices. Additionally, antiplatelet therapy that prevents device-related thrombus formation after ASD closure can possibly exacerbate thrombocytopenia and haemolysis. Therefore, the staged strategy is reasonable from the perspectives of antiplatelet therapy and haemodynamic changes.

Project description:Atrial septal defect (ASD) is a common congenital defect that leads to various hemodynamic complications if untreated. Transcatheter closure (TCC) of isolated secundum ASD is the preferred treatment. Herein we describe a unique malaligned ASD secondary to a membranous chord. With balloon sizing and intracardiac echocardiography (ICE), TCC was successfully pursued. (Level of Difficulty: Beginner.).

Project description:Automated echocardiogram interpretation with artificial intelligence (AI) has the potential to facilitate the serial diagnosis of heart defects by primary clinician. However, the fully automated and interpretable analysis pipeline for suggesting a treatment plan is largely underexplored. The present study targets to build an automatic and interpretable assistant for the transthoracic echocardiogram- (TTE-) based assessment of atrial septal defect (ASD) with deep learning (DL). We developed a novel deep keypoint stadiometry (DKS) model, which learns to precisely localize the keypoints, i.e., the endpoints of defects and followed by the absolute distance measurement with the scale. The closure plan and the size of the ASD occluder for transcatheter closure are derived based on the explicit clinical decision rules. A total of 3,474 2D and Doppler TTE from 579 patients were retrospectively collected from two clinical groups. The accuracy of closure classification using DKS (0.9425 ± 0.0052) outperforms the "black-box" model (0.7646 ± 0.0068; p < 0.0001) for within-center evaluation. The results in cross-center cases or using the quadratic weighted kappa as an evaluation metric are consistent. The fine-grained keypoint label provides more explicit supervision for network training. While DKS can be fully automated, clinicians can intervene and edit at different steps of the process as well. Our deep learning keypoint localization can provide an automatic and transparent way for assessing size-sensitive congenital heart defects, which has huge potential value for application in primary medical institutions in China. Also, more size-sensitive treatment planning tasks may be explored in the future.

Project description:Transcatheter edge-to-edge repair has revolutionized the management of mitral regurgitation in the high surgical-risk population. Iatrogenic atrial septal defects (iASDs) are an obligatory consequence of the procedure. The long-term sequelae of persistent iASDs are unknown but are believed to be dependent on their size, directionality of flow, and underlying hemodynamics. We discuss an uncommon scenario of a post-transcatheter edge-to-edge repair iASD that required immediate closure. (Level of Difficulty: Intermediate.).
