Review
The GORE CARDIOFORM atrial septal defect (ASD) Occluder (GCA) is composed of a platinum-filled nitinol wire frame covered with expanded polytetrafluoroethylene, making it softer and more conformable compared with nitinol mesh devices. After the ASSURED clinical study confirmed the efficacy and safety of the device, it received U.S. Food and Drug Administration approval and a European conformity mark. Our aim was to understand the learning curve implicated in using the GCA for ASD closure in paediatric and adult patients as well as to study the early outcomes. To this end, a review of ASD device closures with GCA in 4 UK centres was conducted between January 2020 and January 2023. Implantation success was the primary outcome; the secondary outcomes were serious adverse events, including new onset arrhythmia. In all, 135 patients were included, and 128 (95%) had successful ASD device closure with GCA. The median patient age was 49 years, the median defect size was 18 mm, and the median device size was 37 mm. The median follow-up time was 6 months (interquartile range 1-14). One device embolisation occurred, and 15 patients (12% of GCA implantations) developed new onset arrhythmia - this was not related to patient age, defect diameter or device oversizing but was positively associated with device size. With growing experience using GCA, the device can be applied to a wide variety of ASD sizes and morphologies. Given the number of successful implantations with an absence of aortic erosion, as well as the ability to perforate through the device should procedures be required in the left atrium, the GCA device is an important addition for interventionists who close atrial septal defects.

BACKGROUND
Holt-Oram syndrome (HOS) is a rare genetic illness, which concerns disturbances in the appearance of the upper limbs, congenital heart malformations, and cardiac conduction diseases. HOS usually requires the implantation of a pacemaker, because of cardiac conduction disturbances.
CASE REPORT
We present the case of a patient with HOS qualified for pacemaker implantation due to overt bradycardia. To prevent the development of heart failure in the future, the His-bundle pacing technique was used. The implantation was successful. In the control, after one year, the man remains in good condition. The pacing was over 90%, and the left ventricular ejection fraction (LVEF) was stable (60%).
CONCLUSIONS
So far, there are no reports on which methods of stimulation are required when it comes to patients with HOS. His-bundle pacing technique is a new type of physiological pacing, which can avoid heart failure.

Review
New generation 3-dimensional matrix array intracardiac echocardiography catheters have become commercially available recently, increasing image plane options compared to 2-dimensional and older generation 3-dimensional intracardiac echocardiography catheters. They are beginning to play an important role in structural heart interventions, especially for transcatheter tricuspid interventions, due to advantages in some situations that increase image quality over transesophageal echocardiography.

Review
At present, the patent foramen ovale (PFO) does not receive the deserved medical attention. The PFO poses a serious threat to health and even the life of mankind. The first respective case report in the medical literature dates back to the 19th century. It led to death. The fact that a PFO is present in roughly 25% of people underscores its overall potential to cause harm. Yet at the same time, the sheer number discourages the medical community from screening for it and from treating it. About 5% of the population have particularly dangerous forms of PFOs. Such PFOs portray a high enough risk for clinical events, the likes of death, stroke, myocardial infarction, or ocular, visceral, and peripheral embolism, to justify screening for them. Highly significant health incidents being at stake, it appears obvious that PFO closure should be used for primary prevention. This is supported by the fact that closing a PFO is the simplest intervention in cardiology, with presumably the highest clinical yield. Being mainly a preventive measure, PFO closure represents a mechanical vaccination. When closing PFOs for one of the rarer therapeutic indications (migraine, platypnea orthodeoxia, etc.), patients automatically profit from the collateral benefit of getting, at the same time, mechanically vaccinated for life against paradoxical embolism. Vice versa, closing a PFO for the prevention of paradoxical embolism betters or cures migraine or exercise dyspnea not infrequently, thereby improving quality of life as a collateral benefit.

Thoracic echocardiography (TTE) can provide sufficient cardiac structure information, evaluate hemodynamics and cardiac function, and is an effective method for atrial septal defect (ASD) examination. This paper aims to study a deep learning method based on cardiac ultrasound video to assist in ASD diagnosis. We chose four standard views in pediatric cardiac ultrasound to identify atrial septal defects; the four standard views were as follows: subcostal sagittal view of the atrium septum (subSAS), apical four-chamber view (A4C), the low parasternal four-chamber view (LPS4C), and parasternal short-axis view of large artery (PSAX). We enlist data from 300 children patients as part of a double-blind experiment for five-fold cross-validation to verify the performance of our model. In addition, data from 30 children patients (15 positives and 15 negatives) are collected for clinician testing and compared to our model test results (these 30 samples do not participate in model training). In our model, we present a block random selection, maximal agreement decision, and frame sampling strategy for training and testing respectively, resNet18 and r3D networks are used to extract the frame features and aggregate them to build a rich video-level representation. We validate our model using our private dataset by five cross-validation. For ASD detection, we achieve AUC, accuracy, sensitivity, specificity, and F1 score. The proposed model is a multiple instances learning-based deep learning model for video atrial septal defect detection which effectively improves ASD detection accuracy when compared to the performances of previous networks and clinical doctors.

Review
This article provides comprehensive insights into the evaluation of simple congenital heart diseases (CHDs) in adults, emphasizing the pivotal role of echocardiography. By focusing on conditions such as congenital aortic stenosis, aortic coarctation, patent ductus arteriosus, atrial septal defects (ASDs), and ventricular septal defects (VSDs), the review underscores echocardiography's intricate contributions to precise clinical decision-making. Echocardiography serves as the primary imaging modality, offering high-resolution visualization of anatomical anomalies and quantification of hemodynamic parameters. It enables tailored therapeutic strategies through its capacity to discern the dimensions, spatial orientation, and dynamic shunt dynamics of defects such as ASDs and VSDs. Moreover, echocardiography's advanced techniques, such as tissue Doppler imaging and speckle tracking, provide detailed insights into atrial mechanics, diastolic function, and ventricular filling kinetics. Integration of echocardiographic findings into clinical practice empowers clinicians to create personalized interventions based on quantified ventricular function, which spans systolic and diastolic aspects. This approach facilitates risk stratification and therapeutic planning, particularly pertinent in heart failure management within the CHD patient population. In summary, echocardiography transcends its role as an imaging tool, emerging as a precision-guided instrument adept at navigating the complexities of simple CHD in adults. Its ability to expedite diagnosis, quantify hemodynamic impacts, and unravel multifaceted functional dynamics culminates in a comprehensive depiction of these conditions. The fusion of these insights with clinical expertise empowers clinicians to navigate the intricate pathways of CHD, crafting tailored therapeutic strategies characterized by precision and efficacy.

Comparative Study
OBJECTIVES
Paradoxical embolism from right-to-left shunt through atrial septal defect (ASD) and patent foramen ovale (PFO) is a well-accepted cause of "cryptogenic" strokes (CS). To better understand the pathogenic role of ASD, we compared ASD patients with CS having a high and low likelihood of being PFO-related.
METHODS
In the Acute Stroke Registry and Analysis of Lausanne, we calculated prevalence of PFO and ASD in CS patients undergoing echocardiography, and calculated odds ratios (OR) when compared to non-CS. Using the Risk of Paradoxical Embolism (RoPE) score, we divided CS PFO patients in high (HL-PFO, RoPE 8-10) and low-likelihood (LL-PFO, RoPE 0-4) PFO-related stroke. We then performed univariate comparison of epidemiological, clinical and radiological variables of ASD patients with both PFO groups.
RESULTS
Among all CS, prevalence of ASD and PFO were 1.3% and 36.8% respectively. When compared to non-CS, ASD and PFO were associated with CS (OR of 5.2, CI= 1.6-16.6, and 2.8, CI= 2.1-3.8). Compared with HL-PFO, ASD patients were older, more often female, had more cardiovascular risk factors and silent strokes. Compared with LL-PFO, ASD patients were younger, more often female, and had less risk factors. No differences were found for clinical and radiological characteristics and clinical outcome.
CONCLUSION
ASD is a rare stroke risk factor for CS. Since characteristics of such patients lie in-between high and low-likelihood paradoxical PFO-strokes, a thorough work-up for other stroke mechanisms is warranted. Individual evaluation of the likelihood of the ASD being causative for stroke may be preferable over routine ASD closure.
