Background: Atrial septal defect (ASD) is a prevalent congenital heart condition in adults, which finally leads to pulmonary hypertension and right heart failure if left untreated. Right heart catheterization (RHC), the current gold standard for determining ASD closure feasibility, is invasive. Thus, a noninvasive prescreening tool is urgently needed., Methods and Results: In a multicenter, retrospective study, we assessed 924 ASD patients (2012-2022) to determine their suitability for ASD closure. Using LASSO regression, we identified predictors for a correctable shunt, enabling us to create the ASD model. The ASD model, comprising of estimated pulmonary artery systolic pressure (ePASP), peak velocity through the pulmonary valve (PV), peak E-wave velocity through the tricuspid valve (TVE), and right atrial longitudinal dimension (RA) by echocardiography, was constructed and exhibited favorable discriminative capability with an area under the curve (AUC) of 0.941 (95% CI: 0.920-0.961) in the derivation group. The model also demonstrated good calibration and discriminative abilities in the validation cohort. When juxtaposed with the earlier congenital heart disease (CHD) model, the newly developed ASD model demonstrated superior predictive capabilities for correctable shunt, supported by the net reclassification index (NRI) [0.063 (95% CI: 0.001-0.127, p = 0.047)] and integrated discrimination improvement (IDI) [0.023 (95% CI: 0.011-0.036, p < 0.001)]., Conclusion: In summary, our research advocates the ASD model as a superior tool for screening suitable ASD defect closure candidates., (© 2024 Wiley Periodicals LLC.)

The hospital admitted a 3-day-old female infant presenting with persistent facial cyanosis and hypoxic symptoms, and echocardiography revealed a congenitally unguarded tricuspid valve orifice with an atrial septal defect. After being followed up until the age of one and a half years, the child underwent bidirectional Glenn's surgery and achieved successful survival., (© 2024 Wiley Periodicals LLC.)

Background: To compare the therapeutic effects of right vertical infra-axillary thoracotomy (RVIAT) and Standard Median Sternotomy (SMS) in the repair of atrial septal defect (ASD) and ventricular septal defect (VSD), and to evaluate the safety and effectiveness of right subaxillary incision technique in the surgical treatment of common congenital heart disease (CHD) in children., Methods: Data of children diagnosed with ASD repair or VSD repair at our center from September 2019 to September 2022 were collected. Based on propensity score matching, 214 children (107 in the RVIAT group and 107 in the SMS group) who completed ASD repair surgery and 242 children (121 in the RVIAT group and 121 in the SMS group) who completed VSD repair surgery were selected for the study. The perioperative and follow-up data of the two surgical approaches were compared to evaluate clinical efficacy., Results: There was no statistically significant difference (p > 0.05) between the two surgical approaches in terms of surgical time, aortic occlusion time, total amount of ultrafiltration fluid, ICU stay time, and hospital stay; The intraoperative blood loss and total postoperative drainage fluid in the RVIAT group were lower than those in the SMS group (p < 0.05); The incidence of postoperative thoracic deformities in the SMS group is higher than that in the RVIAT group., Conclusion: The safety and effectiveness of the two approaches are similar, but RVIAT has less intraoperative bleeding, less postoperative drainage fluid and tube time, and better concealment and cosmetic effects, which is worthy of further clinical promotion and application., (© 2024.

Background: An atrial septal defect (ASD) is considered oval-shaped when its shortest diameter is less than 75% of the longest diameter. Research on percutaneous closure of oval-shaped ASDs is limited, with no known reports of non-fluoroscopic closure for this population., Objective: To assess the effectiveness of non-fluoroscopic percutaneous closure for oval-shaped ASDs., Methods: This single-center retrospective study evaluates patients undergoing non-fluoroscopic percutaneous closure of oval-shaped ASDs, defined by the shortest to longest diameter ratio < 0.75, a circular index of 1.33, or ultrasound visualization of an oval shape. Device size was chosen to be 0-4 mm larger than the defect's longest diameter, based on transthoracic and transesophageal ultrasound measurements., Results: We identified 78 patients (33.3% children, 20.5% males) with a mean age of 27.4 ± 16.3 years and a mean weight of 46.8 ± 19.8 kg. The mean longest diameter and mean shortest diameter of ASDs were 23.3 ± 6.8 mm and 15.8 ± 5 mm, respectively. The mean ratio of the shortest to longest diameter was 0.7 ± 0.1. Percutaneous closure was not attempted in 7/78 (9%) patients. Three out of 71 (4.2%) procedures were fluoroscopy-guided upfront due to technical difficulties, and 5/71 (7%) were converted to fluoroscopy-guided closure. Overall procedural success rate was 98.6% (70/71) including 63/71 (88.7%) performed with zero fluoroscopy. Mean device size was 26.5 ± 7.1 mm. Mean procedural time was 45.3 ± 22.6 min. Eleven intraprocedural complications occurred including 6 arrhythmias, 3 pericardial effusions, and 2 device dislodgements., Conclusion: Transcatheter closure of oval-shaped ASD is safe and feasible. Echocardiography is adequate for adequate operative guidance., (© 2024. The Author(s).)

Objectives: The atrial septal pouch was first recognised in humans in 2006 and, since 2010, has been described in more detail. The first reports on the left-sided atrial septal pouch linked its occurrence with a higher risk of thromboembolic stroke resulting from left atrial thrombus formation. However, subsequent studies have challenged this theory; therefore, the consequences of septal pouch occurrence remain disputed. Currently, in veterinary species, septal pouch occurrence and morphology have been described in sheep and pigs, showing species-related differences. No studies have been conducted on cats. As cats show a species-related risk of aortic thromboembolic disease resulting from left atrial thrombus formation, we aimed to describe the interatrial septum anatomical variations as the first step in the investigation of the relationship between the septal pouch presence and left atrial thrombus formation., Methods: The study was conducted on hearts collected post mortem from 80 cats. After formalin fixation and dissection, a detailed anatomical description of the interatrial septum for all cases was followed by a histopathological analysis of the heart in 25 cases. After dissection, the specimens were embedded in paraffin blocks and stained with haematoxylin and eosin, Masson-Goldner trichrome, Picrosirius Red and Movat pentachrome in a routine manner and evaluated via light microscopy., Results: Our study showed a very high prevalence (95%) of the left-sided septal pouch in cats with a lower incidence (29%) of the right-sided septal pouch. We noted a high morphological variety of the left-sided septal pouch and described anatomical variants not previously reported in the literature., Conclusions and Relevance: The septal pouch is a common anatomical variation of the interatrial septum in cats. Although, based on the current study, we cannot draw further conclusions on the relationship between the left-sided septal pouch and thromboembolic events in cats, the high prevalence of this anatomical entity points to a need of further studies on the topic., Competing Interests: Conflict of interestThe authors declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article.

Purpose: For the repair of atrial/ventricular septal defects (ASD/VSD), transthoracic echocardiography (TTE) is easy to perform, cost-effective, and does not require general anesthesia and intubation. Still, TTE is not universally accepted. To compare efficacy and safety of TTE versus transesophageal echocardiography (TEE) to guide percutaneous ASD/VSD closure., Methods: PubMed, Embase, and the Cochrane library were searched for articles published from their inception to December 2023. The primary outcome was the procedural success rate. The secondary outcomes were residual shunt, late complications, procedure time, and fluoroscopy time. All meta-analyses were performed using a random-effects model., Results: Eight studies and 1295 patients were included. There were no significant differences between TTE and TEE regarding the procedural success rate (OR = 1.93, 95% CI: 0.90-4.13, p = 0.092; I 2  = 52.2%, P heterogeneity  = 0.063) and residual shunt rate (OR = 0.81, 95% CI: 0.38-1.76, p = 0.600; I 2  = 0%, P heterogeneity  = 0.518). Compared with TEE, TTE reduced the frequency of late complications (OR = 0.25, 95% CI: 0.14-0.43, p < 0.001; I 2  = 13.8%, P heterogeneity  = 0.326), reduced the procedure time (WMD = -8.92, 95% CI: -12.08, -5.75, p < 0.001; I 2  = 87.4%, P heterogeneity  < 0.001), and reduced the fluoroscopy time (WMD = -5.08, 95% CI: -9.59, -0.56, p = 0.028; I 2  = 95.6%, P heterogeneity  < 0.001). The sensitivity analyses showed that the results of the meta-analyses were robust., Conclusion: Compared with TEE, TTE showed no differences regarding the rates of success and residual shunt, but there were lower rates of late complications and shorter procedure and fluoroscopy times., (© 2024 The Author(s).

Abstract: Re-expansion pulmonary edema (RPE) is a rare complication of minimally invasive cardiac surgery (MICS). We present a case of RPE following atrial septal defect (ASD) closure using a thoracotomy approach and cardiopulmonary bypass (CPB). REP contributes to significant morbidity and extends the length of stays in the intensive care unit. Understanding the pathophysiology and risk factors of RPE allows us to prevent or minimize the incidence., (Copyright © 2024 Copyright: © 2024 Annals of Cardiac Anaesthesia.)

Background: Atrial septal defect (ASD) is a common congenital heart disease, and currently, transcatheter intervention is the most common clinical treatment method. However, certain complications still occur during the percutaneous process, among which occluder loss and displacement are rare but serious complication. Although the probability of occluder loss and displacement is low, severe cases can endanger life., Case Presentation: Here, we report the case of a patient who underwent ASD closure in which the occluder fell off into the aortic arch, the detached occluder was recovered through catheter intervention, and the patient underwent ASD closure again., Conclusions: In this case report, we highlight that although percutaneous closure of an ASD is regarded as a routine procedure, clinicians should remember the possibility of complications, especially occluder loss and displacement. Therefore, interventionist should carefully evaluate the situation before intervention closure, establish standardized interventional treatment procedures, and provide timely treatment follow-up., (© 2024.

Objective: To analyze the prenatal and postnatal outcomes of fetuses with d-TGA and to determine whether prenatal echocardiography may predict postnatal urgent BAS., Study Design: A retrospective study of fetuses with d-TGA, for which fetal echocardiography was performed at our tertiary hospital from January 2018 to May 2023. We assessed the appearance of the septum primum and the FO flap in the four-chamber view as to whether the FO had a restrictive appearance during measurement of the diameter of the FO at its maximal angle to the attachment point. Color Doppler was used to detect VSDs and measure its diameter both in the four-chamber view and when visualizing the outlets of the great arteries in the sagittal section of the heart., Results: During the study period, 64 fetuses were diagnosed with d-TGA, which was also confirmed postnatally. Of these, 16 fetuses were excluded due to additional cardiac anomalies or the inability to reach the mother. In total, 48 cases were included in this series. In our study, the FO diameter was significantly decreased in the urgent BAS group, compared with the fetuses without urgent BAS (5.1 mm vs 6.3 mm). A cut off of 6 mm for the FO diameter (sensitivity, 73.3 %; specificity, 72.2 %; area under the curve [AUC], 0.764) and 3.2 mm for the VSD diameter (sensitivity, 75 %; specificity, 75 %; AUC, 0.728) suggested urgent BAS., Conclusion: Prenatal echocardiography performed after 37 weeks of gestation in fetuses with d-TGA provides valuable information to estimate the need for postnatal urgent BAS that would prevent immediate life-threatening complications., Competing Interests: Declaration of competing interest The authors declare that there is no conflict of interest regarding the publication of this paper., (Copyright © 2024 Elsevier Masson SAS.

Background: Cardiac catheterizations in horses are mainly performed in the right heart, as access to the left heart traditionally requires an arterial approach. Transseptal puncture (TSP) has been adapted for horses but data on follow-up and closure of the iatrogenic atrial septal defect (iASD) are lacking., Hypothesis/objectives: To perform TSP and assess postoperative complications and iASD closure over a minimum of 4 weeks., Animals: Eleven healthy adult horses., Methods: Transseptal puncture was performed under general anesthesia. Serum cardiac troponin I concentrations were measured before and after puncture. Weekly, iASD closure was monitored using transthoracic and intracardiac echocardiography. Relationship between activated clotting time and anti-factor Xa activity during postoperative enoxaparin treatment was assessed in vitro and in vivo., Results: Transseptal puncture was successfully achieved in all horses within a median duration of 22 (range, 10-104) minutes. Balloon dilatation of the puncture site for sheath advancement was needed in 4 horses. Atrial arrhythmias occurred in 9/11 horses, including atrial premature depolarizations (N = 1), atrial tachycardia (N = 5), and fibrillation (N = 3). Serum cardiac troponin I concentrations increased after TSP, but remained under the reference value in 10/11 horses. Median time to iASD closure was 14 (1-35) days. Activated clotting time correlated with anti-factor Xa activity in vitro but not in vivo., Conclusions and Clinical Importance: Transseptal puncture was successfully performed in all horses. The technique was safe and spontaneous iASD closure occurred in all horses. Clinical application of TSP will allow characterization and treatment of left-sided arrhythmias in horses., (© 2024 The Author(s).

A newborn with hypoplastic left heart syndrome underwent a Norwood procedure with a Sano shunt. A month later, he had an atrial septal defect (ASD) stent placed due to ASD size and flow restriction. Three weeks later, he had sudden bradycardia and cardiac arrest in the intensive care unit. He was resuscitated and cannulated for extracorporeal membrane oxygenation (ECMO) through a right neck approach. An attempt to wean him from ECMO a week later failed due to hypoxia. Echocardiography showed ASD flow restriction and a chest x-ray showed flattening of the left atrial side of the ASD stent from chest compression resulting in a restrictive ASD. The patient underwent surgical removal of the ASD stent with ASD enlargement and was successfully weaned from ECMO after surgery., Competing Interests: Declaration of Conflicting InterestsThe author(s) declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article.

Background: The criteria for ASD closure in patients with PAH are different between the AHA/ACC and the ESC guidelines. We aimed to study the prevalence of patients with different guideline criteria for ASD closure and its impact on the clinical outcome after closure., Methods and Results: A retrospective cohort study recruiting patients who underwent ASD closure from 2011-2020 was conducted in a single university hospital. Patients were grouped into ASD closure recommended (class I, class IIa, and class IIb) and ASD closure not recommended groups (class III). The primary outcome was the prevalence of patients with discordant criteria and the clinical outcomes and echocardiographic parameters after ASD closure. A total of 17 of 66 ASD patients (25.8 %) were diagnosed with ASD with pulmonary hypertension. Two patients were excluded due to incomplete right heart catheterization data. 13 patients (86.7 %) were classified as ASD-closure recommended group by both guidelines. Two patients, classified as class IIb by ACC/AHA guidelines, were unsuitable for ASD closure by ESC guidelines. After ASD closure, all 15 patients reported functional class improvement and no significant difference in the echocardiography parameters. However, the number of patients with a low probability of PHT was higher in patients with ESC guideline-recommended closure., Conclusions: Most patients (86.7 %) are in concordant classification regarding ASD closure recommendations. The ESC guidelines are more restrictive than the AHA/ACC guidelines, allowing fewer patients for ASD closure. However, the clinical outcomes after ASD closure are not significantly different between these guidelines., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024.

Background: The left atrium approach for atrial fibrillation (AF) ablation requires an atrial transseptal puncture that may cause an iatrogenic atrial septal defect (iASD). This study aimed to investigate the incidence and predictors of iASD in catheter ablation, assessed by transthoracic echocardiography (TTE), a relatively non-invasive technique frequently employed in follow-up., Methods: This retrospective study included 639 patients (489 male; 60.2±10.7years) who underwent initial catheter ablation for AF between May 2005 and June 2018. All patients underwent preprocedural transesophageal echocardiography (pre-TEE), preprocedural TTE (pre-TTE), and TTE one day after the procedure (post-TTE). iASD incidence after 6months (6M), preprocedural characteristics, and procedure methods were evaluated., Results: Patent foramen ovale (PFO) was diagnosed in 42 patients (6.6%) using pre-TEE and in 11 patients using pre-TTE (26.2% of the patients with PFO in pre-TEE). Among the 597 patients without PFO, 497 underwent 6M-TTE. iASD was observed in 59.6% of patients using post-TTE and 4.6% using 6M-TTE. In the univariate logistic regression analysis, the total diameter of the sheath through the septum (odds ratio 1.15, p<0.001) or two sheaths through a single puncture (odds ratio 4.17, p=0.001) were independent risk factors on iASD incidence in 6M-TTE. iASD was also more likely to occur via cryoballoon ablation using a larger sheath than radiofrequency catheter ablation., Conclusions: iASD was not a rare complication. A larger sheath diameter or two sheaths through a single puncture were associated with the incidence of iASD., Competing Interests: Declaration of competing interest The authors declare that there is no conflict of interest., (Copyright © 2024 The Authors.

Total knee arthroplasty (TKA) is the most common joint arthroplasty procedure and is shown to be a reliable and efficacious way to improve quality of life. Individuals with interatrial wall abnormalities (IAWAs), such as atrial septal defect or patent foramen ovale (PFO), are at increased baseline risk for stroke and overall lifetime morbidity. The purpose of our study was to elucidate the association between IAWAs and perioperative TKA outcomes.We performed a retrospective cohort study utilizing the Healthcare Cost and Utilization Project National Inpatient Sample database. Admissions for TKA between 2010 and 2019 were identified using the international classification of disease (ICD)-9 and ICD-10 procedure codes. Patients with ICD-9-clinical modification (CM) diagnosis code 7455 or ICD-10-CM diagnosis code Q211 were assigned to the IAWA cohort, the primary exposure. Confounding variables included basic demographics, baseline health status, and surgical facility characteristics. The primary outcomes studied were medical complications, implant-related complications, and admission mortality. Univariate and adjusted multivariable regression analyses were used to identify associations.Compared to patients in the non-IAWA cohort, those in the IAWA cohort had significant risks for same-admission medical complications (odds ratio [OR] 5.77, 95% confidence interval [CI] 4.59-7.15; p  < 0.001), implant-related complications (OR 1.55, 95% CI 1.09-2.12; p  = 0.009), stroke (OR 77.46, 95% CI 58.4-101.2; p  < 0.001), venous thromboembolism (VTE; OR 3.78 95% CI 2.47-5.51; p  < 0.001), and mortality (OR 8.36, 95% CI 3.54-16.52; p  < 0.001) following TKA.Compared to patients without IAWAs, those with IAWAs who undergo TKA have higher risks for same-admission medical and implant-related complications as well as same-admission mortality. Similarly, these patients have higher risks for same-admission stroke and VTE. Further research on perioperative TKA management in patients with IAWAs is needed.Level of Evidence is III: retrospective cohort study., Competing Interests: None declared., (Thieme.

Patent foramen ovale (PFO) and atrial septal defects (ASDs) are two types of interatrial communications with unique clinical presentations and management strategies. The PFO is a normal part of fetal development that typically closes shortly after birth but may persist in as many as 25% to 30% of adults. The communication between atria may result in paradoxic embolism and embolic stroke. On the other hand, ASDs (anatomically defined as secundum, primum, sinus venosus, and coronary sinus in order of prevalence) typically result in right heart volume overload and are often associated with other congenital defects. The diagnostic methods, treatment options including surgical and percutaneous approaches, and potential complications are described. Both conditions underline the significance of precise diagnosis and appropriate management to mitigate risks and ensure optimal patient outcomes., Competing Interests: Disclosure C.H.

The evolution of percutaneous procedures that use transseptal puncture to treat left-sided structural heart disease has led to the emergence of iatrogenic atrial septal defects as a potential complication. These defects can result in hemodynamic decompensation and worsening clinical outcomes. Some iatrogenic atrial septal defects require immediate closure, others do not. This case report presents 2 patients who underwent transcatheter edge-to-edge mitral valve repair with transseptal puncture and required iatrogenic atrial septal defect closure (1 immediate and 1 delayed). The goal of this report is to highlight iatrogenic atrial septal defect assessment and the possible need for closure after transseptal puncture., (© 2024 The Authors.

Iatrogenic inferior vena cava (IVC)-left atrium (LA) shunt is a rare complication in atrial septal defect (ASD) surgery, caused by mistaking the Eustachian valve for the lower margin of the ASD. In this report, we describe the case of a 45-year-old woman who experienced circulatory collapse at termination of cardiopulmonary bypass during surgical IVC-LA shunt repair. Transesophageal echocardiography helped identify stenosis between the IVC and the right atrium, caused by a residual original incorrectly placed ASD patch. Removal of most of the patch led to improvement in circulatory failure., Competing Interests: The authors declare no conflicts of interest., (Copyright © 2024 International Anesthesia Research Society.)

Median sternotomy has been the conventional approach for correction of atrial septal defect despite poor cosmetic results at times. Right anterior minithoracotomy was, therefore, assessed as an alternative procedure with a better cosmetic outcome., Material and Methods: from April 2008 through February 2017 102 patients underwent correction of atrial septal defect with the use of normothermic perfusion on a beating heart through right anterior minithoracotomy involving a short incision through the fourth intercostals space and the direct cannulation. The 75 were female and 27 male end the averaging age 19,2±2,0 years. The corrected defects included atrial septal defect type II, atrial septal defect with short aortic edge, atrial septal defect with short inferior edge, atrial septal defect with short superior edge, sinus venosus superior type atrial septal defect and sinus venosus inferior type atrial septal defect. The length of the skin incision varied from 4 to 10 cm, depending on the age of the patient., Results: There was no operative or late mortality or major morbidity. The mean cardiopulmonary bypass time was 19±4 minutes, the duration of mechanical ventilation after surgery in patients was 2,4±0,9 hours. Cosmetic result was very satisfactory in all patients., Conclusions: The right anterior minithoracotomy incision is a safe and effective alternative to a median sternotomy for correction of atrial septal defect. Cosmetic results are highly satisfactory.

Superior sinus venosus defects (SVD) are interatrial communications located above the confines of the oval fossa, where unroofing of the right upper pulmonary vein leads to its anomalous drainage to the superior venacava. Recent emergence of transcatheter closure of these defects using covered stents is an attractive alternative option especially in adults with additional comorbidities. This article focuses on various aspects of non-surgical closure of SVD, including patient selection, appropriate hardware options, step-by-step procedural details, evolution and modifications in the techniques over the last decade, protocols for follow-up evaluation, and potential complications associated with this intervention., Competing Interests: Disclosure The author has nothing to disclose., (Copyright © 2024 Elsevier Inc.

A nine-year old boy presented following a chest x-ray for COVID-19 infection that showed cardiomegaly. Transthoracic echocardiogram revealed a large atrial septal defect, dilated right heart, and normal function. Surgical repair was performed eight weeks after his COVID diagnosis. After weaning from cardiopulmonary bypass, pulmonary artery pressures were 2/3 systemic and ectopy was seen, requiring inotropes, nitric oxide, lidocaine, and amiodarone. He was discharged on postoperative day (POD) 5. On POD 6, he presented with acute right foot ischemia. Computed tomography showed a large aortic thrombus, requiring emergent thrombectomy. Coagulopathy workup was negative. Cardiac magnetic resonance imaging (CMR) and catheterization showed reduced biventricular function and diastolic dysfunction. Diuretics and β blockers were started, with gradual improvement in left ventricular systolic function., Competing Interests: Declaration of Conflicting InterestsThe author(s) declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article.

Backgrounds: Effectiveness of patent foramen ovale (PFO) closure on relief of migraine, is still unclear. We sought to analyse the long-term (>10 years) effects of interatrial septal shunt repair on disabling migraine performing a retrospective non-randomised study., Methods: Clinical records of patients with disabling, medication-refractory migraine and PFO or significant ASD referred to our centre for closure from 2006 to 2018, were analysed., Results: Forty -six patients (38 female, mean age 40.0 ± 3.7 years) with PFO and 32 patients with significant ASD (28 female, mean age 38.0 ± 4.1 years) submitted to transcatheter closure had a pre-existing disabling migraine with mean Migraine Disability Assessment Score (MIDAS) of 35.8 ± 4.7. After a mean follow-up of 118.2 ± 19.1 months (range 96 to 144), 72 out of 78 patients were still followed-up: in all subjects, aura was abolished, and migraine improved also in patients without aura. The mean MIDAS significantly decreased from baseline value ( p  < 0.01). Complete migraine resolution was associated in PFO patients with a shorter history of migraine, a more severe thrombophilic profile, a more severe Right-to-Left Shunt (RLS) and larger left atrial diameter and volume, and in ASD patients with bidirectional shunt., Conclusions: Device-based repair of PFO/ASD in patients with migraine was associated with abolition of aura and symptoms reduction in the long-term period.

We report a compressed air worker who had diffuse cutaneous decompression sickness with pain in his left shoulder and visual disturbance characteristic of migraine aura after only his third hyperbaric exposure. The maximum pressure was 253 kPa gauge with oxygen decompression using the Swanscombe Oxygen Decompression Table. He was found to have a very large right-to-left shunt across a 9 mm atrial septal defect. He had transcatheter closure of the defect but had some residual shunting with release of a Valsalva manoeuvre. Thirty-two other tunnel workers undertook the same pressure profile and activities in the same working conditions during the maintenance of a tunnel boring machine for a total of 233 similar exposures and were unaffected. As far as we are aware this is the first report of shunt-mediated decompression sickness in a hyperbaric tunnel worker in the United Kingdom and the second case reported worldwide. These cases suggest that shunt-mediated decompression sickness should be considered to be an occupational risk in modern compressed air working. A right-to-left shunt in a compressed air worker should be managed in accordance with established clinical guidance for divers., Competing Interests: The authors report no conflicts of interest in this work., (Copyright: This article is the copyright of the authors who grant Diving and Hyperbaric Medicine a non-exclusive licence to publish the article in electronic and other forms.)

Background: Sinus venosus atrial septal defect (SVASD) is a rare congenital cardiac anomaly comprising 5% to 10% of all atrial septal defects. Although surgical closure is the standard treatment for SVASD, data on outcomes have been confined to small cohorts. Thus, we conducted a systematic review of the outcomes of SVASD repair., Methods and Results: The primary outcome was death. Secondary outcomes encompassed atrial fibrillation, sinus node dysfunction, pacemaker insertion, cerebrovascular accident, reoperation, residual septal defect, superior vena cava obstruction, and reimplanted pulmonary vein obstruction. Pooled incidences of outcomes were calculated using a random-effects model. Forty studies involving 1320 patients who underwent SVASD repair were included. The majority were male patients (55.4%), with 88.0% presenting with associated anomalous pulmonary venous connection. The weighted mean age was 18.6±12.5 years, and the overall weighted mean follow-up period was 8.6±10.4 years. The in-hospital mortality rate was 0.24%, with a 30-day mortality rate of 0.5% reported in 780 patients. Incidences of atrial fibrillation, sinus node dysfunction, pacemaker insertion, and cerebrovascular accident over the long-term follow-up were 3.3% (2.18%-4.93%), 6.5% (5.09%-8.2%), 2.23% (1.34%-3.57%), and 2.03% (0.89%-2.46%) respectively. Reoperation occurred in 1.36% (0.68%-2.42%) of surgeries, residual septal defect in 1.34% (0.69%-2.42%), superior vena cava obstruction in 1.76% (1.02%-2.9%), and reimplanted pulmonary vein obstruction in 1.4% (0.7%-2.49%)., Conclusions: This is the first comprehensive analysis of outcomes following surgical repair of SVASD. The findings affirm the safety and effectiveness of surgery, establishing a reference point for evaluating emerging transcatheter therapies. Safety and efficacy profiles comparable to surgical repair are essential for widespread adoption of transcatheter treatments.

Background: Transcatheter correction of sinus venosus defects (SVDs) using balloon-mounted covered stents provides an attractive surgical alternative. Surgery may be complicated by superior vena caval or right upper pulmonary vein (RUPV) stenosis, sinus nodal dysfunction, and residual additional pulmonary veins., Objectives: Being a new intervention, technical modifications would simplify the procedure, improve universal applicability, and reduce or tackle complications., Methods: Patients were included if balloon interrogation of cavoatrial junction confirmed closure of SVD and redirected RUPV to the left atrium. A single-center experience was analyzed to summarize the procedural modifications over 8 years. Transesophageal echocardiogram (TEE) on follow-up was done to identify residual shunt, RUPV flows, and stent thrombosis., Results: A total of 100 patients including 9 children with a median age of 35 years (range, 4-69 years) underwent SVD closure after balloon interrogation. Among 57 patients balloon interrogated in the first 5 years, 70% underwent transcatheter closure, with 2 failures. RUPV occlusion caused the exclusions. Inclusions improved to 94% among the subsequent 65 balloon interrogations when RUPV protection was implemented, with 1 failure. Stent embolization caused the 3 failures warranting surgery. Recent modifications included limited transesophageal echocardiogram without anesthesia, avoiding venovenous circuit, interrogation with semicompliant balloons, trans-septal RUPV protection, overlapping stents to permit additional vein drainage to superior vena cava and tackle embolizations. There were no deaths. Minor complications included stent embolizations stabilized in catheterization laboratory in 2 patients, left innominate vein jailing in 2 patients, insignificant residual flows, and nonocclusive asymptomatic stent thrombosis in 4 patients., Conclusions: Procedural success was 97%. Recent modifications increased patient inclusions, decreased complications, and simplified the intervention., Competing Interests: Funding Support and Author Disclosures The authors have reported that they have no relationships relevant to the contents of this paper to disclose., (Copyright © 2024 American College of Cardiology Foundation.

Background: Balloon sizing (BS) has been used for device size selection in percutaneous atrial septal defect (ASD) closure. Due to its limitations, alternative imaging techniques like three-dimensional transesophageal echocardiography (3D-TEE) are valuable for guiding ASD device size selection during ASD closure procedures. The purpose of this study was to compare ASD sizing using measurements obtained from 3D-TEE to those utilizing the standard balloon sizing method., Methods: We identified 53 patients with single secundum type ASD without PFO who underwent percutaneous closure at the Tehran Heart Center between 2019 and 2022. Balloon sizing was performed in all patients with the stop-flow technique, and the choice of device size was determined based on the sizing derived from BS. 3D-TEE imaging was performed before the intervention, and the ASD shape and quality of ASD rims were assessed., Results: Among the 53 patients who underwent single ASD device closure, multiple 3D TEE measurements significantly correlated with balloon sizing results. This included defect area, perimeter, and diameter obtained from 3D-TEE images multi-planar reconstruction. ASD perimeter detected by 3D TEE had the best correlation with BS results. When divided by the shape of ASD, there was no significant difference between our 3D-images data and BS in round or oval-shaped ASDs., Conclusion: The 3D-TEE study is reliable for assessing ASD configurational characteristics in percutaneous device closure candidates. 3D-TEE has the potential to accurately determine the appropriate device size and reduce complications, costs, and procedural duration. Further research is needed to validate these findings and establish the role of 3D-TEE measurements in guiding the best treatment decisions for ASD closure., (© 2024 Wiley Periodicals LLC.)

Purpose: This study was designed to investigate the application value of the atrial septum excursion index (ASEI) in fetuses with isolated restrictive foramen ovale (RFO) or redundant foramen ovale flap (RFOF) and the outcomes of these fetuses., Methods: This was a retrospective study. Healthy pregnant women who were examined by antenatal fetal echocardiography from January 1, 2019 to December 31, 2021, at Sir Run Run Shaw Hospital were enrolled. One hundred seventy-seven (177) fetuses were categorized into three groups by diagnosis: (1) RFOF (n = 33), (2) RFO (n = 21), and (3) normal (n = 123). Fetal echocardiographic features and postnatal outcomes were collected., Results: The median ASEIs were 0.50 (range, 0.41-0.65) in the control group, 0.76 (range, 0.67-0.88) in the RFOF group and 0.31 (range, 0.14-0.35) in the RFO group, and the differences were significant (p < 0.001). The ratios of right atrium/left atrium, right ventricle/left ventricle, and pulmonary artery diameter to aorta diameter (PA/AO) and the pulmonary annulus Z-scores were greater in fetuses with RFOF and RFO than in the controls (p < 0.05). Twenty-seven of 33 fetuses (87.9%) with RFOF and 19 of 21 fetuses (90.5%) with RFO had good outcomes after birth., Conclusion: The ASEI may be a new tool for quantitatively assessing the mobility of foramen ovale flaps in fetuses with isolated RFOF or RFO., (© 2024 Wiley Periodicals LLC.)

When the atrioventricular node is damaged, accessory pathways can perform primary atrioventricular conduction but may spontaneously degrade during childhood. After surgical atrial septal defect repair during infancy, an adolescent male presented with fatigue due to iatrogenic complete atrioventricular node block with a degrading antegrade accessory pathway resulting in symptomatic bradyarrhythmia.

Atrial Septal Defect closure in childhood and early adulthood has a good prognosis, but in older individuals the risk-benefit ratio is not as straightforward. We report a 57-year-old man who was easily fatigued when exercising. The cardiac examination revealed a wide and fixed splitting of S2, a pulmonary ejection systolic murmur grade III/VI, and increased jugular venous pressure. The transesophageal echocardiography showed Atrial Septal Defect secundum with a diameter of 20 mm, L-to-R shunt, and 5 mm, a thin and floppy inferior rim. The patient underwent surgical Atrial Septal Defect closure. The deficient posteroinferior rim occurs only in 3.3% of patients with secundum Atrial Septal Defect. This condition will enhance the likelihood of occluder dislodgement in the transcatheter closure approach. We learn from this case that surgical Atrial Septal Defect closure may be an option for elderly patients if there is an inadequate, thin, and floppy inferior rim or no comorbidities.

To identify risk factors associated with post-pericardiotomy syndrome (PPS) in patients undergoing surgical repair of atrial septal defects (ASD). A single-center retrospective study. Tertiary academic hospital. Included were patients of all ages who underwent surgical ASD repair, while exclusion criteria included the absence of post-operative electrocardiogram (ECG), lack of follow-up post-discharge and factors hindering ECG interpretation. Demographic and clinical data, including ECG changes indicative of pericardial inflammation, were collected. The primary outcome measure was the development of PPS, determined based on the standardized European Society of Cardiology (ESC) criteria. Among 190 patients who underwent surgical ASD repair, 154 (81%) met the inclusion criteria. Of these, 25 (16%)in total developed PPS, of which 60% were ≥ 18 years of age and 56% female. Significant associations relating both early ECG changes and pre-discharge pericardial effusion with subsequent occurrence of PPS were found in both univariate and multivariate analyses. The study establishes correlations of both early post-operative ECG changes indicative of inflammation and pre-discharge pericardial effusion with subsequent occurrence of PPS in patients undergoing surgical ASD repair. Both utilizing the standardized ESC definition of PPS and incorporating a physician-validated ECG evaluation strengthened the methodologic approach in establishing these relationships. The results also highlight the importance of considering age as a potential risk factor for PPS. Further research is needed to validate these findings and explore additional risk factors predicting early identification and management of patients at high risk for PPS following surgical ASD repairs., (© 2024.

Bacground: Patients who underwent ultrafast track on the operating table and fast track extubation in the pediatric intensive care unit for 2 to 6 h after secundum atrial septal defect surgery in the pediatric age group were compared., Methods: Between January 2013 and February 2017, 60 pediatric patients (24 boys, 36 girls; Mean age 7.5 ± 4.6 years) whose secundum atrial defect was closed were retrospectively analyzed. The patients were separated as those who were extubated on the operating table (Group1, n  = 28) and those extubated in the pediatric intensive care unit within 2-6 h postoperatively (Group2, n  = 32)., Results: No difference was found in demographic data and preoperative catheter information between the groups. Cardiopulmonary bypass time was 20(18-25)/27.5(20-30)minutes (p:0.001), the cross-clamp time was 10(10-15)/15(11-20)minutes(p:0.004), the postoperative drainage amount was 50(25-50)/60(32.5-100)ml(p:0.013), the length of stay in the intensive care unit was 1(1--1)/1(1-2)day(p:0.025), the length of stay after intensive care was 3(2-3)/3(3-4)days(p:0.001) and the total hospital stay was 4(3-4)/5(4-5.5) days ( p  < 0.001), which were respectively shorter for the group 1 compared to 2. Postoperative blood product replacement, positive inotrope support, pericardial effusion, mortality, and morbidity were not detected in either groups., Conclusion: In this study, it was observed that the UFT extubation was safe for the patients who were operated for secundum ASD, in the pediatric age group, and had a cross-clamp time not exceeding 15 min. It was found that the amount of drainage, length of stay in the intensive care unit, post-intensive care unit, and the total hospital stay of patients extubated on the operating table were shorter.

Clinical Data: Female, seven years old, referred to our service complaining about congestive heart failure symptoms due to mitral valve regurgitation and atrial septal defect. Technical description: Echocardiographic findings compatible with Barlow's disease and atrial septal defect, ostium secundum type., Operation: She was submitted to mitral valvuloplasty with chordal shortening and prosthetic posterior ring (Gregori-Braile®) along with patch atrioseptoplasty., Comments: Mitral valve regurgitation is a rare congenital heart disease and Barlow's disease is probably rarer. Mitral valve repair is the treatment of choice.

We report the case of a 9-year-old male with severe congenital pulmonary valve stenosis referred to our centre for percutaneous valvotomy. On admission, trans-thoracic echocardiogram confirmed a unicuspid pulmonary valve with a peak/mean pulmonary valve gradient of 91/53 mmHg and a pulmonary annulus of 13.8 mm (-0.8 Z Score). It also showed an enlarged RV (RV/LV ratio 0,9). During cardiac catheterisation, an additional atrial septal defect (secundum) with significant left to right shunt (Qp/Qs > 2) was diagnosed, which was not amenable to percutaneous closure. The patient was referred for surgical repair.The atrial septal defect was closed by a direct running suture. The repair of the unicuspid valve consisted in bicuspidisation by a large commissurotomy to the left anterior wall of the pulmonary artery. The neo-commissure was created with two separate patches of autologous pericardium secured to the wall of the pulmonary root. The adjustment of the effective height of the pulmonary valve leaflets was done by trimming the patches and a triangular plication of the newly created posterior leaflet. Perioperative echocardiogram showed a peak gradient of 15 mm Hg and trivial pulmonary regurgitation. The total cross-clamp time was 92 min and the bypass time 123 min with a favourable evolution after the surgery.The particularity of the case is represented by the complexity of the bicuspidisation procedure. Using this technique, a tailored approach is needed for every patient.

Objective: We sought to simplify reporting of outcomes in congenital heart surgery that compares well-defined patient groups and accommodates multiple stakeholder needs while being easily understandable., Methods: We selected 19 commonly performed congenital heart surgeries ranging in complexity from repair of atrial septal defects to the Norwood procedure. Strict inclusion/exclusion criteria ensured the creation of 19 well-defined diagnosis/procedure cohorts. Preoperative, procedural, and postoperative data were collected for consecutive eligible patients from 9 centers between January 1, 2016, and December 31, 2021. Unadjusted operative mortality rates and hospital length of stay for each of the 19 diagnosis/procedure cohorts were summarized in aggregate and stratified by each center., Results: Of 8572 eligible cases included, numbers in the 19 diagnosis/procedure cohorts ranged from 73 for tetralogy of Fallot repair after previous palliation to 1224 for ventricular septal defect (VSD) repair for isolated VSD. In aggregate, the unadjusted mortality ranged from 0% for atrial septal defect repair to 28.4% for hybrid stage I. There was significant heterogeneity in case mix and mortality for different diagnosis/procedure cohorts across centers (eg, arterial switch operation/VSD, n = 7-42, mortality 0%-7.4%; Norwood procedure, n = 16-122, mortality 5.3%-25%)., Conclusions: Reporting of institutional case volumes and outcomes within well-defined diagnosis/procedure cohorts can enable centers to benchmark outcomes, understand trends in mortality, and direct quality improvement. When made public, this type of report could provide parents with information on institutional volumes and outcomes and allow them to better understand the experience of each program with operations for specific congenital heart defects., (Copyright © 2023 The American Association for Thoracic Surgery.

The concomitant large atrial septal defect closure, endocardial biatrial cryoablation and tricuspid valve replacement with mitral homograft in a patient with adult congenital heart disease is presented. Because of the severely dilated right ventricle and leaflet tenting, tricuspid valve replacement was considered. The patient refused both mechanical and stented biological prosthesis due to personal beliefs, therefore, the alternative valve substitute was proposed. Relevant decision-making process, preoperative diagnostic work-up and surgical technique are highlighted with satisfactory outcomes., Competing Interests: Declaration of conflicting interestsThe authors declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article.

Objective: In this study, we aimed to evaluate quality of life and parental attitudes in children who underwent an atrial septal defect closure procedure with a transcatheter or surgical method in childhood and whether they continued their lives with similar activities to their healthy peers by comparing the two groups., Methods: Patient forms to define sociodemographic and clinical features, the Questionnaire for Measuring Health-Related Quality of Life in Children and Adolescents (KINDL) to measure the quality of life of children, and the Parent-Child Relationship Test (Parental Attitude Research Instrument) to measure parental attitudes were used., Results: The groups were similar in terms of age and sex. The mean quality of life scale scores were high in all groups, and there was no statistically significant difference between the scores. Parents of the patients who underwent closure received higher scores from the demographic attitudes and recognition of quality subdimension compared to the parents of the healthy group., Conclusions: The quality of life of children with atrial septal defect closure was found to be similar to their healthy peers. Additionally, the effects of surgical or percutaneous closure of atrial septal defect on quality of life are similar. Children with atrial septal defect closure perceive their health status as well as their healthy peers, and this perception does not cause any difference in the attitudes and behaviours of families.
