Abstract
Background Due to their delayed onset of symptoms, atrial septal defects (ASDs) are common congenital cardiac defects that are frequently identified in adulthood. In cases of complicated ASD morphology, transcatheter closure employing devices such as the Amplatzer septal occluder (ASO) presents with difficulties. While the Amplatzer cribriform occluder (ACO) has gained popularity as a specialized option, little is known about its initial use or results, especially in older patients. Objective The goal of this study was to describe the early experience with ACO in patients aged 18 to 38 years who had ASDs at a tertiary care hospital in Pakistan, with a focus on the device's efficacy, safety, and viability. Methods A total of six cases with ASD who underwent ASD closure with the ACO were retrospectively reviewed at Lady Reading Hospital-Medical Teaching Institution (LRH-MTI), Peshawar, Pakistan. All the required data were obtained from the hospital management information system (HMIS), including patient demographics, defect features, procedure specifics, complications, and outcomes. Results Of all patients, 83.3% (n=5) were females and 16.7% (n=1) were males, and the mean age of the group was 27.7 ± 7.9 years. The results of echocardiography showed variation, with a mean fenestrated septum size of 22.4 mm (SD ± 5.4) and a range of device sizes between 18 and 35 mm. The ideal access method for device deployment in every situation was the right femoral vein. There were very few complications; in one instance, a residual shunt necessitated replacing the device. During the six-month follow-up, no complications were found, and all patients were discharged without any problems. Conclusion In conclusion, our study indicates that the ACO is a good choice for young adult patients' ASD closure, showing good safety and efficacy. To verify these results and evaluate the long-term functioning of the device, more prospective trials with larger cohorts are required.

Abstract
Atrial septal defects (ASDs) present a significant healthcare challenge, demanding accurate and timely diagnosis and precise management to ensure optimal patient outcomes. Artificial intelligence (AI) applications in healthcare are rapidly evolving, offering promise for enhanced medical decision-making and patient care. In the context of cardiology, the integration of AI promises to provide more efficient and accurate diagnosis and personalized treatment strategies for ASD patients. In interventional cardiology, sometimes the lack of precise measurement of the cardiac rims evaluated by transthoracic echocardiography combined with the floppy aspect of the rims can mislead and result in complications. AI software can be created to generate responses for difficult tasks, like which device is the most suitable for different shapes and dimensions to prevent embolization or erosion. This paper reviews the current state of AI in healthcare and its applications in cardiology, emphasizing the specific opportunities and challenges in applying AI to ASD diagnosis and management. By exploring the capabilities and limitations of AI in ASD diagnosis and management. This paper highlights the evolution of medical practice towards a more AI-augmented future, demonstrating the capacity of AI to unlock new possibilities for healthcare professionals and patients alike.

Abstract
Over the past seven decades, significant advancements and innovations have occurred in the field of percutaneous atrial septal defect (ASD) closure using transcatheter-based devices. This article focuses on the current literature surrounding the three Food and Drug Administration (FDA)-approved devices for ASD and patent foramen ovale (PFO) closure in the United States, namely, the Amplatzer Septal Occluder (ASO), Amplatzer Cribriform Occluder, and Gore Cardioform ASD Occluder. The ASO has been widely used since its FDA approval in 2001. Studies have shown its high success rate in closing ASDs, especially small-sized defects. The RESPECT trial demonstrated that PFO closure using the ASO reduced the risk of recurrent ischemic stroke compared to medical therapy alone. The Closure of Atrial Septal Defects With the Amplatzer Septal Occluder Post-Approval Study (ASD PMS II) evaluated the safety and effectiveness of ASO in a large cohort of patients, reporting a high closure success rate and rare hemodynamic compromise. The Amplatzer Cribriform Occluder is designed for the closure of multifenestrated ASDs and has shown promising results in small-scale studies. It successfully closed the majority of fenestrated ASDs, leading to improved right ventricular diastolic pressure without major complications. The REDUCE trial compared PFO closure using the Gore Helex Septal Occluder and Gore Cardioform Septal Occluder with antiplatelet therapy alone. The study demonstrated that PFO closure significantly reduced the risk of recurrent stroke and brain infarction compared to antiplatelet therapy alone. However, the closure group had a higher incidence of atrial fibrillation or atrial flutter. There is a risk of atrial fibrillation with the use of ASO as well. The FDA-approved Gore Cardioform ASD Occluder showed excellent performance in the ASSURED clinical study. The device achieved high technical success and closure rates, with low rates of serious adverse events and device-related complications. A meta-analysis comparing transcatheter ASD closure with surgical closure revealed that the transcatheter approach had a high success rate, lower rates of adverse events, and shorter hospital stays compared to surgery, without any mortality. Complications associated with transcatheter ASD closure have been reported, including femoral arteriovenous fistulas, device embolization, cardiac erosion, aortic incompetence, and new-onset migraine. However, these complications are relatively rare. In conclusion, transcatheter ASD closure using FDA-approved devices has proven to be safe and effective in the majority of cases. These devices offer excellent closure rates, reduced risk of recurrent stroke, and shorter hospital stays compared to surgery. However, careful patient selection and follow-up are necessary to minimize complications and ensure optimal outcomes.

Abstract
Swiss-cheese atrial septal defect (ASD) is a malformation characterized by multi-fenestrated interatrial defects. Here, we describe a vignette of a 23-year-old man with Swiss-Cheese ASD characterized by two defects with areas of 0.74 cm2 and 0.44 cm2, complicated with an atrial septal aneurysm successfully repaired with a cribriform amplatzer septal occluder (ASO) via the percutaneous transcatheter approach. This case emphasizes the importance of attaining a clear view of three-dimensional structures for proper device selection and deployment in repair as additional structural defects such as concomitant aneurysms impose significant challenges.

Abstract
BACKGROUND Two separate ostium secundum atrial septal defects are a challenging substrate for device closure due to lack of a well-described strategy or an adequately evaluated protocol. METHODS This is a prospective study comprising 20 patients with 2 atrial septal defects who underwent device closure. All of them underwent balloon interrogation (BI) of the intervening tissue to decide 1- versus 2-device strategy. During BI, if the flow through both the defects could be stopped completely implying adequate mobility of the separating tissue, a single device strategy was used. The size of the device in this subset was determined by BI diameter. In case the flow persisted, 2 devices were used to close the defects separately. RESULTS The mean age was 24±17 years. The main defect size was (mean 14.5 mm±SD 2.69 mm), whereas the second defect measured (mean 8.5±SD 3.02 mm). The tissue separating the 2 defects was measured (mean 6.1±SD 2.6 mm). In 15 of them, based on the BI results, a single device was used successfully to close both the defects without a residual shunt. In the remaining 5 patients, 2 devices were used. There were no complications during the procedure or at follow-up period of 41.9±16.9 months. CONCLUSIONS BI in patients with 2 atrial septal defects is helpful in defining 1- versus 2-device strategies and in choosing the size of the device to be used. Nearly 3/4 of the patients may get away with a single device for closing both the defects successfully thereby decreasing the cost and complexity of the procedure.

Abstract
BACKGROUND To date, extensive experience in transcatheter closure of fenestrated atrial septal aneurysm (ASA) in the pediatric population is limited. METHODS To report on procedural feasibility, efficacy, and long-term outcome, we enrolled all children submitted to an attempt of transcatheter closure of fenestrated ASA at two, large volume, pediatric cardiology units (Naples and Massa, Italy) between April 2000 to May 2020. RESULTS This retrospective study included 139 patients (median age 9 years [range 2-18] and weight 36 kg [range 10-102]); 19 (13.7%) children were ≤20 kg (range 10-20) and 14 (10.1%) were ≤5 years old. Single perforation was observed in 28 patients (20.1%), while 111 patients (79.9%) had multifenestrated ASA. The median size of the main defect was 15 mm (range 6-34) and 25 patients (18%) had a defect ≥20 mm. The procedural success rate was 99% (95% confidence interval [CI]: 94.9-99.8) using a single device in 75 (69%), two devices in 31 (28%), and three devices in 3 (3%) cases. Early minor adverse events (AEs) occurred in four patients (2.8%). Late minor AEs were recorded in one patient (0.7%) over a median follow-up of 5 years ([range 0-18 years; total 890.2 person-years, and with 30 patients (22%) followed ≥10 years). Neither mortality nor major AEs were recorded. Freedom from AEs was 99.1% at 10-15 years (95% CI: 93.5-99.8%), without any difference according to atrial septum anatomy or patient age and weight. CONCLUSION Transcatheter closure of fenestrated ASA is technically feasible and effective in children with excellent long-term outcomes.

Abstract
Atrial septal defects (ASDs) are one of the most common congenital heart disorders encountered by cardiologists. Percutaneous ASD closure for secundum ASD is commonly performed not only for children but also for adults, given its non-inferiority to surgical repair. The choice of closure technique should be based on assessing a patient's baseline comorbidities, including the presence of pulmonary hypertension, supraventricular tachycardias, and left ventricular diastolic dysfunction. Furthermore, anatomical features and defect types determined using echocardiography need to be considered when developing a management plan. Percutaneous closure is often the preferred method, given its comparable successful rate to surgical repair while also being far less invasive.

Transcatheter closure of multiple secundum atrial septal defects using multiple occluder devices: A comparative experience between pediatric and adult patients. Ann Pediatr Cardiol 2022; 15:128-137. [PMID: 36246750 PMCID: PMC9564409 DOI: 10.4103/apc.apc_269_20] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/03/2020] [Revised: 05/17/2021] [Accepted: 05/19/2021] [Indexed: 11/25/2022] Open
Abstract
Background: Device closure of multiple atrial septal defects (MASDs) is frequently done using a single centrally deployed septal or cribriform occluder, but multiple devices are needed for large defects separated more than 6 mm. There is a concern about complications while using multiple devices, especially in children. Methods: Patients who received multiple devices for closure of MASD were grouped according to their age and analyzed for procedural techniques, immediate and late complications. MASDs closed by a single device were not included. Balloon sizing was done when echocardiographic images were suboptimal before simultaneous device deployment through two venous accesses or sequential deployment through one access. Duration and number of antiplatelet drugs and residual flows were analyzed on follow-up. Results: Twenty-five patients received multiple devices. Balloon interrogation was performed in 16/18 adults but only in 2/7 children. Device size was 2–5 mm larger than echocardiographic defect size or equal to balloon waist. There were no procedural failures; 7/25 showed small postprocedural residual flows. Complications including embolization in one, arrhythmia in one, and cobra deformity in two were managed successfully. On a median follow-up of 5.5 years (1–12 years), residual flows disappeared in 4/7 and there were no major late complications. Conclusions: Use of multiple devices for closing MASD is feasible with good technical success. Echocardiography and balloon interrogation are the keys for success. Simultaneous deployment is often needed and sequential delivery is feasible rarely if the defects are far apart. Minor residual leaks are common but improve on follow-up. There are no significant new complications on long-term follow-up.

Abstract
AIM To report on the feasibility, efficacy and long-term outcome of transcatheter closure of fenestrated Atrial Septal Aneurysm (ASA). METHODS Between April 2000 and May 2020, 568 patients with fenestrated ASA underwent transcatheter closure at two large-volume Pediatric Cardiology and GUCH Units (Naples and Massa, Italy). Procedural indications were cardiac volume overload in 223 patients (39%) or prophylaxis of paradoxical embolization in 345 patients (61%). Patients' median age and weight were 42 years (range 19-52) and 66 kg (range 54-79), respectively. One-hundred and thirty-nine patients (25%) were younger than 18 years. RESULTS Single fenestration was found in 311 patients (55%) (Group 1), whereas 257 patients (45%) had multifenestrated ASA (Group 2). The procedure was successful in all but seven patients (1.2%). In Group 1, closure was achieved with a single device. In Group 2, one device was used in 168 patients (67%), two devices in 74 patients (28%), three devices in 12 patients (5%), and four devices in 1 patient (0.3%). The early complication rate was 3%, without any difference according to anatomy or patient's age. At discharge, complete shunt closure was higher in Group 1 (92% vs. 72%, P < 0.0001), without any difference between groups at the last follow-up evaluation (100% vs. 99%, P = 0.12). Procedural safety was persistent during the long-term follow-up (mean 7.2 ± 5.4, range 0-19 years): freedom from adverse events was 97% at 10-15 years. Seventeen patients (3%) were submitted to reintervention, mostly as prophylaxis of paradoxical embolization. CONCLUSION Transcatheter closure of perforated ASA is technically feasible in a high percentage of cases, with excellent long-term outcomes.

Abstract
Transcatheter closure has been widely accepted as a highly effective way to treat abnormal blood flows and/or embolization of thrombus in the heart. It allows the closure of four types of congenital heart defects (CHDs) and stroke-associated left atrial appendage (LAA). The four types of CHDs include atrial septal defect (ASD), patent foramen ovale (PFO), patent ductus arteriosus (PDA), and ventricular septal defect (VSD). Advancements in the materials and configurations of occlusion devices have spurred the transition from open-heart surgery with high complexity and morbidity, or lifelong medication with a high risk of bleeding, to minimally invasive deployment. A variety of occlusion devices have been developed over the past few decades, particularly novel ones represented by biodegradable and 3D-printed occlusion devices, which are considered as next-generation alternatives to conventional Nitinol-based occlusion devices due to biodegradability, customization, and improved biocompatibility. The aim here is to comprehensively review the next-generation occlusion devices in terms of materials, configurations, manufacturing methods, deployment strategies, and (if available) experimental results or clinical data. The current challenges and the direction of future work are also proposed. STATEMENT OF SIGNIFICANCE: Implantation of occlusion devices has become a widely accepted and highly effective treatment for occluding abnormal blood/thrombus flow within the heart. Due to the serious complications such as erosion and displacement of conventional Nitinol-based occluders, next-generation occluders with reduced risk of complications and improved biocompatibility has emerged. Here, we comprehensively review the next-generation occluders developed for atrial septal defect (ASD), patent foramen ovale (PFO), patent ductus arteriosus (PDA), ventricular septal defect (VSD), and left atrial appendage (LAA), with special emphasis on biodegradable occluders. Besides, intelligent materials (e.g., automatically deployable shape memory polymers) and rapid customized manufacturing methods (3D/4D printing) for the fabrication of occluders are also introduced. Lastly, the directions of future work are highlighted.

Abstract
Purpose : Fenestrated atrial septal defects (F-ASDs) in the pediatric population pose a challenge for transcatheter device closure since multiple devices are not preferred in small hearts. Oversizing the Amplatzer Septal Occluder (ASO) to cover the surrounding fenestrations usually distorts the central waist as well as the disc profile and often defeats the purpose. This is a retrospective observational study with an aim to assess the feasibility and safety of cribriform ASO in closing F-ASDs in small children. Methods: Sixteen children with F-ASD who underwent device closure with cribriform ASO were included in the study. The fenestrated septal length (FSL) and the total septal length (TSL) were measured on transesophageal echocardiogram. A device size which was 1.5–2 times the FSL but smaller than the TSL was selected. The defect was closed with a device passed through a relatively centrally placed smaller fenestration. Results: The median age of the cohort was 5 years (2.5–10.5). Majority (14/16) required 25 or 30 mm cribriform ASO. Aneurysmal interatrial septum was seen in most of our patients (11/15). All the patients had successful device implantation. Complete closure of the defect was seen in 11 patients while 5 patients had insignificant residual shunt at a median follow-up of 40 months (1–60 months). There were no other complications. Conclusions: Cribriform ASO can be used safely and effectively in closing F-ASDs in children. Deployment of the device through a small central hole allows covering maximum fenestrations and gives more stability to the device. Residual shunts, although not infrequent, are insignificant.

Abstract
Multiple atrial septal defects (ASDs) are one type of secundum ASD, most of which have an atrial septal aneurysm or long interdefect distance. In our retrospective single-center study, we reviewed different closure strategies for multiple ASDs. We analyzed 50 patients who underwent percutaneous transcatheter closure from May 2011 to July 2019. Information on the patients' characteristics, operation procedure, occluder selection, and complications was collected. According to the feature of the defects and device choice, multiple ASDs were divided into five groups. A successful operation was achieved in every patient. A total of 50 patients were implanted with 58 devices, with 26 patients implanted with a single standard ASD occluder (ASDO); six patients were implanted with double standard ASDOs, and only one patient was implanted with three standard ASDOs. There were 17 patients whose closure was made using the small-waist–big-edge ASDO. Seventy-six percent of the patients (38/50) had an immediate residual shunt. During the mean follow-up of 25.76 ± 22.53 months, the complete closure rate was 92%. Except for two patients with a transient atrioventricular block, individualized experience with percutaneous transcatheter closure for multiple ASDs was effective in a single-center study. After a mid- to long-term follow-up, the multiple ASDOs and small-waist–big-edge ASDO had no serious adverse events or complications.

Abstract
Several devices have been designed and tried over the years to percutaneously close atrial septal defects (ASDs). Most of the devices were first experimented in animal models with subsequent clinical testing in human subjects. Some devices were discontinued or withdrawn from further clinical use for varied reasons and other devices received Food and Drug Administration (FDA) approval with consequent continued usage. The outcomes of both discontinued and currently used devices was presented in some detail. The results of device implantation are generally good when appropriate care and precautions are undertaken. At this time, Amplatzer Septal Occluder is most frequently utilized device for occlusion of secundum ASD around the world.

Abstract
Transcatheter closure has become an accepted alternative to surgical repair for ostium secundum atrial septal defects (ASD). However, large ASDs (>38 mm) and defects with deficient rims are usually not offered transcatheter closure but are referred for surgical closure. Transcatheter closure also remains controversial for other complicated ASDs with comorbidities, additional cardiac features and in small children. This article not only provides a comprehensive, up-to-date description of the current indications and contra-indications for ASD device closure, but also further explores the current limits for transcatheter closure in controversial cases. With the devices and technology currently available, several cohort studies have reported successful percutaneous closure in the above-mentioned complex cases. However the feasibility and safety of transcatheter technique needs to be confirmed through larger studies and longer follow-up.

Abstract
The purpose of this review is to discuss the management of atrial septal defects (ASD), paying particular attention to the most recent developments. There are four types of ASDs: ostium secundum, ostium primum, sinus venosus, and coronary sinus defects. The fifth type, patent foramen ovale-which is present in 25 to 30% of normal individuals and considered a normal variant, although it may be the seat of paradoxical embolism, particularly in adults-is not addressed in this review. The indication for closure of the ASDs, by and large, is the presence of right ventricular volume overload. In asymptomatic patients, the closure is usually performed at four to five years of age. While there was some earlier controversy regarding ASD closure in adult patients, currently it is recommended that the ASD be closed at the time of presentation. Each of the four defects is briefly described followed by presentation of management, whether by surgical or percutaneous approach, as the case may be. Of the four types of ASDs, only the ostium secundum defect is amenable to percutaneous occlusion. For ostium secundum defects, transcatheter closure has been shown to be as effective as surgical closure but with the added benefits of decreased hospital stay, avoidance of a sternotomy, lower cost, and more rapid recovery. There are several FDA-approved devices in use today for percutaneous closure, including the Amplatzer® Septal Occluder (ASO), Amplatzer® Cribriform device, and Gore HELEX® device. The ASO is most commonly used for ostium secundum ASDs, the Gore HELEX® is useful for small to medium-sized defects, and the cribriform device is utilized for fenestrated ASDs. The remaining types of ASDs usually require surgical correction. All of the available treatment modes are safe and effective and prevent the development of further cardiac complications.
