Meta-Analysis
BACKGROUND
The exact incidence and predictors of new-onset atrial fibrillation (AF) after percutaneous closure of patent foramen ovale (PFO) are unknown.
OBJECTIVE
We sought to find post-procedural AF incidence rates and differences due to different screening strategies and devices.
METHODS
A systematic search was conducted in Cochrane, MEDLINE and EMBASE. Controlled trials fulfilling the inclusion criteria were included into this meta-analysis. The incidence of new-onset AF was the primary outcome. Further parameters were surveillance strategy, device type, AF treatment and neurological events. New AF was determined as early onset within one month after implantation and late thereafter.
RESULTS
8 controlled trials and 16 cohort studies were eligible for quantitative analysis. 7643 patients received percutaneous PFO closure after cryptogenic stroke or transient ischaemic attack, 117 with other indications, whereas 1792 patients formed the control group. Meta-analysis of controlled trials showed an AF incidence of 5.1% in the interventional and 1.6% in the conservative arm, respectively (OR 3.17, 95% CI 1.46-6.86, P = 0.03, I = 55%). 4.7% received high-quality surveillance strategy with Holter-ECG or Loop recorder whereby AF incidence was overall higher compared to the low-quality group with 12-lead ECG only (3.3-15% vs. 0.2-4.3%). Heterogeneous results on time of AF onset were found, limited by different follow-up strategies. CardioSEAL and Starflex seemed to have higher AF incidences in early and late onset with 4.5% and 4.2%, respectively.
CONCLUSION
Percutaneous PFO closure led to higher AF post-procedural incidence compared to the conservative strategy. Heterogeneity in surveillance and follow-up strategy limited the generalizability.

Secundum atrial septal defects (sASDs) are common congenital cardiac defects mostly treated using a transcatheter approach. However, small children (<15 kg) are still undergoing surgical sASD closure in many centres. Although both options have been proved to have excellent results in children, comparative data of the two techniques are missing for patients ≤ 15 kg. The medical records of children ≤ 15 kg who underwent sASD surgical (group A) and transcatheter (group B) closure between 2010 and 2023 were reviewed retrospectively. Twenty-five children in group A and twenty-two in group B were included (mean weight 8.9 kg in group A and 10.3 kg in group B). The main indications for closure were right heart enlargement and failure to thrive. Major complications occurred in two patients in group A and none in group B. Minor complications occurred in eight patients in group A and one in group B. At last follow-up, symptoms resolved completely or improved significantly for all infants, with the exception of failure to thrive in the sub-population of children with extra-cardiac comorbidities. sASD closure can be performed safely in symptomatic infants ≤ 15 kg, even in the presence of comorbidity, and should not be postponed. However, in patients with extra-cardiac comorbidities, the only indication of growth retardation must be carefully evaluated.

INTRODUCTION
Though less common in the current era, surgical closure of secundum atrial septal defects (ASD2) is still performed in certain clinical situations. Guidelines currently recommend lifelong follow-up with transthoracic echocardiograms (TTE) for patients who have undergone a surgical ASD2 closure. The goal of this study was to determine the utility of follow-up TTE in patients who underwent an uncomplicated ASD2 closure.
METHODS
Chart review was performed on patients who had a surgical ASD2 closure between April 1, 1996, and August 30, 2021. Patients were excluded if they had other congenital heart disease, had a diagnosis of a residual ASD2, atrial/ventricular arrhythmias, pulmonary hypertension, heart failure, or did not have a follow-up TTE > 6 months after the procedure. The most recent TTEs and clinic notes were evaluated.
RESULTS
A total of 30 patients met the criteria. The median age at ASD2 surgery was 4.0 years (IQ; 1.9-10.5). ASD2 was closed via patch repair in 16 patients and primarily closed in 14 patients. The most recent TTE was performed a median of 9.5 years (IQ; 4.0, 14.7) after ASD2 closure. Two patients had mild right atrial and ventricular dilation, one patient had mild right atrial dilation, and one patient had mild right ventricular dilation. All other patients had qualitatively normal right-sided chamber sizes. All patients had normal biventricular function (left ventricular fractional shortening (median 36% (IQ; 33, 42)), no evidence of residual atrial shunts, and no evidence of pulmonary hypertension. No patient was on any cardiac medications at last clinic visit. Four patients were discharged from cardiology clinic and 10 patients were lost to follow-up. There were no deaths. Twenty-four patients had 46 repeat echocardiograms > 1 year after ASD2 with no change in clinical management.
CONCLUSION
In patients who underwent an uncomplicated ASD2 closure, there were no significant abnormalities noted on follow-up TTEs. The need for repeat lifetime TTEs and their frequency, in this uncomplicated population, should be reassessed if larger studies with longer follow-up confirm these initial findings.

Atrial septal defect secundum is a common type of congenital heart defect and even more common among children born premature. The aim of this study was to assess premature birth as a potential associated risk factors for cardiac morbidity in children with isolated ASD II. In this retrospective national registry-based case-control study all children born in Sweden between 2010 and 2015 with an isolated ASD II diagnosis were included. Association between premature birth and cardiac morbidity in children with isolated ASD II was assessed by different outcomes-models using conditional logistic regression and adjustments were made for confounding factors. Overall, 11% of children with an isolated ASD II received treatment for heart failure. Down syndrome was the only independent risk factors for associated with cardiac morbidity in children with ASD II (OR = 2.25 (95%CI 1.25-4.07). Preterm birth in children was not associated with an increased risk of ASD II cardiac morbidity.

Background Pulmonary hypertension (PH) is a debilitating cardiovascular disorder characterized by abnormally elevated blood pressure within the lungs. The diverse range of causes and varied clinical presentations contribute to the complexity of its diagnosis and management. In eastern India and surrounding areas, awareness of PH remains limited, and resources for its management are scarce. This study aims to address this knowledge gap by investigating clinical characteristics and treatment approaches adopted for PH patients in eastern India. Methods This retrospective-prospective cohort study included patients diagnosed with PH, defined by a pulmonary artery systolic pressure (PASP) > 50 mmHg or a mean pulmonary artery pressure (mPAP) >20 mmHg, between July 2015 and October 2023. Data retrieved from hospital records formed the retrospective cohort, while the prospective cohort comprised patients directly recruited for the study. Results The PULMOEAST study enrolled 93 patients with confirmed PH, divided into prospective (59 patients) and retrospective (34 patients) cohorts. The most prevalent cause of PH was congenital heart disease (CHD), with shunt lesions (59.13%), followed by complex CHD (13.97%) and idiopathic PH (20.43%). Six additional patients presented with rare causes of PH, and three experienced transient PH following atrial septal defect device closure. Geographic distribution revealed that 72.04% of patients originated from eastern India, while 18.27% hail from other eastern states and 8.6% from neighboring countries. Patients exhibited varying functional classes (FC), with 57 classified as FC-II and 31 classified as FC-III. Treatment strategies primarily involve supportive medications and pulmonary vasodilators. Monotherapy was administered to 26 patients (27.95%), dual therapy to 50 patients (53.76%), and triple therapy to one patient. Notably, 16 patients did not receive any vasodilator therapy as they were waiting for further evaluation. Among the vasodilator regimen, two patients received Selexipag. Three patients underwent intervention for shunt lesion closure, including one patient who received a fenestrated atrial septal occluder implant. Additionally, one patient underwent clot removal for pulmonary thromboembolism. Despite the overall positive response to treatment, the study recorded eight fatalities (8.6%) during the observation period. However, most patients exhibited significant improvement, including a decrease in functional class, during a mean follow-up duration of 14.31 months. Conclusion The PULMOEAST study undertook a comprehensive exploration of PH in eastern India and surrounding regions, revealing a stark dominance of CHD as the primary culprit. The study confirmed the pivotal role of echocardiography as a readily available and effective tool for both initial and follow-up evaluations in resource-scarce settings. It painted a hopeful picture by showcasing significant clinical improvement in most treated patients, with supportive medications and pulmonary vasodilators playing a crucial role. However, the diverse etiologies, limited access to PH-specific resources, and lack of widespread awareness within the region continue to pose substantial challenges for patients. The study underscores the need for refined diagnostic approaches, cost-effective management strategies, collaborative care initiatives, and enhanced patient education to optimize PH care and improve outcomes in eastern India.

We report a unique intraoperative finding of an additional double left atrial appendage (LAA) during an arterial switch operation with ventricular septal defect closure in a 4-month-old girl. Immediately after the procedure, a prolapsing mass within the left atrium (LA) on the transesophageal echocardiogram raised concerns of a possible thrombus. The LAA was clearly visible with a pressure monitoring line which was put intraoperatively. To investigate further, cardiopulmonary bypass was resumed, and the heart was arrested and explored. There was an appendage-like structure, separate from the one that had the pressure monitoring line, which was inverted inside. It was pulled out from outside clearly establishing a double LAA. This report illustrates an example of a diagnostic dilemma caused by a double atrial appendage which was invaginated into LA masquerading as a mass or thrombus.

BACKGROUND
Patients with atrial septal defect (ASD) exhibit distinctive electrocardiogram (ECG) patterns. However, ASD cannot be diagnosed solely based on these differences. Artificial intelligence (AI) has been widely used for specifically diagnosing cardiovascular diseases other than arrhythmia. Our study aimed to develop an artificial intelligence-enabled 8-lead ECG to detect ASD among adults.
METHOD
In this study, our AI model was trained and validated using 526 ECGs from patients with ASD and 2,124 ECGs from a control group with a normal cardiac structure in our hospital. External testing was conducted at Wuhan Central Hospital, involving 50 ECGs from the ASD group and 46 ECGs from the normal group. The model was based on a convolutional neural network (CNN) with a residual network to classify 8-lead ECG data into either the ASD or normal group. We employed a 10-fold cross-validation approach.
RESULTS
Statistically significant differences ( < 0.05) were observed in the cited ECG features between the ASD and normal groups. Our AI model performed well in identifying ECGs in both the ASD group [accuracy of 0.97, precision of 0.90, recall of 0.97, specificity of 0.97, F1 score of 0.93, and area under the curve (AUC) of 0.99] and the normal group within the training and validation datasets from our hospital. Furthermore, these corresponding indices performed impressively in the external test data set with the accuracy of 0.82, precision of 0.90, recall of 0.74, specificity of 0.91, F1 score of 0.81 and the AUC of 0.87. And the series of experiments of subgroups to discuss specific clinic situations associated to this issue was remarkable as well.
CONCLUSION
An ECG-based detection of ASD using an artificial intelligence algorithm can be achieved with high diagnostic performance, and it shows great clinical promise. Our research on AI-enabled 8-lead ECG detection of ASD in adults is expected to provide robust references for early detection of ASD, healthy pregnancies, and related decision-making. A lower number of leads is also more favorable for the application of portable devices, which it is expected that this technology will bring significant economic and societal benefits.

Review
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.

Review
Congenital heart disease (CHD), birth defect with the highest incidence rates worldwide, and is mainly characterized by the abnormal internal structure of the heart or/and the anatomical structure of great vessels. In the past few decades, CHD repair surgery through standard median sternotomy incision combined with cardiopulmonary bypass (CPB) technology has been considered the gold standard for surgical correction of heart and great vessels. With the promotion and clinical application of interventional catheterization technology, transcatheter closure of CHD under radioactive radiation has gradually been recognized and applied. However, its radiation exposure and potential complications related to arteriovenous vessels still face challenges. In recent years, an increasing number of surgeons have explored new surgical procedures, for the safe and effective treatment of CHD, as far as possible to reduce surgical trauma, avoid radiation exposure, and improve the cosmetic effect. Therefore, on the premise of satisfactory exposure or guidance, how to integrate ultrasound and percutaneous interventional technology remained the focus of the exploration. This mini-review highlights and summarizes the signs of progress of ultrasound intervention in the last decade that have proven the effectiveness and operability of a well-established procedure for percutaneous closure of congenital heart diseases under echocardiographic guidance only. We discuss potential diseases that will benefit from this emerging procedure based on this progress. Owing to the crucial advantages played by this strategy in the treatment of CHD, better understanding and promotion of this less exploited field may contribute to the development of therapeutics targeting CHD, improve medical utilization rate, promote the optimization of medical resources, and ultimately achieve precise and efficient medical treatment.
