Atrioseptostomy balloon catheter is an essential item to have on our shelves. However, the recall and shortage in production of the commonly used balloon atrioseptostomy catheters posed an imminent threat to our patients. Herein, we present the case of a newborn with a post-natal diagnosis of simple transposition of great arteries and restrictive atrial communication where repeated static balloon atrial septostomy using a 9 mm x 20 mm Sterling balloon failed to improve his status. We had to improvise per-operatively a new bespoke technique to perform a vital pull-through balloon atrial septostomy. The distal third of a 10 mm x 20 mm semi-compliant Cristal balloon was exteriorised out the tip of a 6-Fr 55 cm Cook Flexor sheath in the left atrium, and both were simultaneously pulled back to the right atrium to create an 8 mm septal defect. The procedure was successful without any complications. The baby was weaned off prostaglandin on day 3 and surgically repaired on day 5 with excellent results.

Background: Transcatheter (TC) atrial septal defect (ASD) closure has been the mainstay of therapy for secundum-type ASDs for over 20 years., Aims: This nationwide cohort evaluated the long-term outcome of transcatheter-closed ASDs., Methods: The study enrolled every transcatheter ASD closure performed in Finland from 1999 to 2019. Five age, sex, and municipality-matched controls per ASD patient were gathered from the general population. The median follow-up period was 5.9 years (range 0-20.8). We used the hospital discharge register to gather all hospital visits and diagnoses. Closure complications and echocardiographic changes were collected from the electronic health records., Results: Transcatheter ASD closure was performed in 1000 patients (68.5% females) during the study period. The median (range) age at the time of the procedure was 37.9 (1.8-87.5) years. ASD patients had an increased risk for new-onset atrial fibrillation (RR 2.45, 95% CI: 1.84-3.25), migraine (RR 3.61, 95% CI: 2.54-5.14), ischemic heart disease (RR 1.73, 95% CI: 1.23-2.45), ventricular fibrillation/tachycardia (RR 3.54 (95% CI: 1.48-8.43) and AV conduction disorder (RR 3.60, 95% CI: 1.94-6.70) compared to the control cohort. Stroke risk was not increased (RR 1.36, 95% CI: 0.91-2.03). Adverse events occurred in 6.3% ( n  = 63) of the patients, including four erosions and ten device embolizations., Conclusion: After TC closure of ASD, patients had a higher risk of new-onset atrial fibrillation and migraine than controls without ASD . As novel findings, we found an increased risk for ischemic heart disease, AV conduction disorders, and ventricular fibrillation/tachycardia.Key messagesEven though patients have an excellent overall prognosis after percutaneous ASD closure, the increased incidence of major comorbidities like atrial fibrillation and heart failure prompts more thorough lifelong follow-up.This study's novel findings revealed the increased risk for ischemic heart disease, AV conduction disorders, or ventricular tachycardia/fibrillation during the follow-up.Major complications after the closure are rare; erosion is seen in 0.4% of the patients and embolization in 1.0% of the patients.

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.

Superior sinus venosus defect is a communication between the right and left atrium located above the upper margin of the oval fossa, immediately inferior to the junction of the superior vena cava and the right atrium. It is systematically associated with partial anomalous pulmonary venous drainage, especially of the right upper pulmonary vein. Surgical repair has been the gold standard approach to close that defect. Introduced in 2014, percutaneous closure has gradually become a safe and effective alternative to surgery in carefully selected patients, although worldwide experience remains limited. This article provides an appraisal of the patients' selection process and a step-by-step description of the procedure as well as a comprehensive review of its outcomes., Competing Interests: Funding Support and Author Disclosures This work was supported by the French Federation of Cardiology (to Dr Hascoet) and the French Society of Cardiology (to Dr Batteux).

Objective: Despite the establishment of transcatheter closure as the treatment of choice in adults with secundum atrial septal defects (ASDs), the effectiveness of this approach in the elderly is disputed. This systematic review and meta-analysis aims to explore the impact of transcatheter ASD closure in patients ≥60 years old., Methods: We systematically searched four major electronic databases (PubMed, CENTRAL (Cochrane Central Register of Controlled Trials), Scopus and Web of Science), ClinicalTrials.gov, article references and grey literature. Primary outcomes were the right ventricular end-diastolic diameter (RVEDD) and the New York Heart Association functional class change, whereas secondary outcomes included systolic pulmonary arterial pressure (sPAP), left ventricular end-diastolic diameter (LVEDD), brain natriuretic peptide (BNP), tricuspid valve regurgitation (TR) change, as well as the rate of atrial arrhythmias and all-cause mortality., Results: In total, 18 single-arm cohorts comprising 1184 patients were included. RVEDD was reduced after ASD closure (standardised mean difference (SMD) -0.9, 95% CI -1.2 to -0.7). Elderly patients had 9.5 times higher odds of being asymptomatic after ASD closure (95% CI 5.06 to 17.79). Furthermore, ASD closure improved sPAP (mean difference (MD) -10.8, 95% CI -14.6 to -7), LVEDD (SMD 0.8, 95% CI 0.7 to 1.0), TR severity (OR 0.39, 95% CI 0.25 to 0.60) and BNP (MD -68.3, 95% CI -114.4 to -22.1). There was a neutral effect of ASD closure on atrial arrhythmias., Conclusions: Transcatheter ASD closure is beneficial for the elderly population since it improves functional capacity, biventricular dimensions, pulmonary pressures, TR severity and BNP. However, the incidence of atrial arrhythmias did not change significantly after the intervention., Prospero Registration Number: CRD42022378574., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2023.

Background: The data on the use of Gore Cardioform Septal Occluder (GCA; W. L. Gore and Associates, Inc.) for atrial septal defect (ASD) with deficient rims is limited., Methods: All patients evaluated by transesophageal echocardiogram (TEE) for ASD occlusion were included. TEE planes at 35°, 0°, and 90° were assessed for anterior-superior (AS) and posterior (P), anterior-inferior (AI) and posterior-superior (PS), as well as superior (S) and inferior (I) rims. ASD size >20 mm, and rims less than 5 mm were defined as large and deficient, respectively. We included patients who had a procedural failure along with the patients in whom the procedure was not attempted after echocardiogram in the unsuccessful group., Results: In 148 patients, the median weight, age, and ASD size were 36 kg (range, 8-60 kg), 11.8 years (range, 1-60 years), and 14.2 ± 8.28 mm, respectively. One or more deficient rims were noted in 112 of 148 (75.7%): 99 (67%) AS, 36 (24%) P, 17 (11%) AI, 30 (20%) PS, 26 (18%) S, and 33 (22%) I. ASD closure was performed in 115 (78%) patients. The procedure was successful in 111 (96.5%) patients with procedural failure in 4 (3.4%) patients. Multiple deficient rims were associated with reduced procedural success (OR 0.36, 95% CI, 0.25-0.56). On multivariate analysis deficient P, PS, and I rims were associated with an unsuccessful group (P = .001, .046, and .005, respectively). Complications included 1 device embolization, 1 vascular injury, and 5 arrhythmias., Conclusions: Transcatheter closure of ASDs with deficient rims is feasible using GCA. Large ASDs with deficient P, PS, and I rims were associated with unsuccessful closure. Risk stratification and comprehensive evaluation of ASD rims is vital for the use of GCA.

Objective: To evaluate the safety and efficacy of the Hanoi ASD procedure, which is totally endoscopic surgery for atrial septal defect (ASD) repair on beating heart. In addition, the present study also aimed to analyze the learning curve for this procedure., Methods: From May 2016 to February 2023, 198 consecutive ASD patients weighing ≥20 kg were enrolled in the retrospective study. The Hanoi ASD procedure includes (1) unilateral or bilateral femoral arterial cannulation; (2) two or three 5 mm trocars and a 15 mm port; (3) ASD repair on beating heart, preventing air embolism with CO 2 insufflation and keeping the left atrium full of blood; and (4) not snaring the inferior vena cava. Cumulative sum (CUSUM) analysis was used to evaluate the cardiopulmonary bypass (CPB) and operation time learning curves. Variables among the learning curve phases were compared., Results: The CPB and operation times were 90 (72 to 115) min and 180 (150 to 220) min, respectively. Total drainage volume was 190 (120 to 290) mL. No endoscopic failure or major complications were complications were excluding factors causing bias, the CUSUM CPBtime analysis for the remaining 131 patients included 3 phases. Phase 1 was the initial learning period (cases 1 to 34), phase 2 represented the technical competence period (cases 35 to 54), and phase 3 was the challenging period (cases 55 to 131)., Conclusions: The Hanoi ASD procedure is safe and feasible for repairing ASD in patients weighing ≥20 kg. According to the learning curve analysis, 34 cases were required to achieve technical efficiency, and 54 cases were required to address highly challenging cases., 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: To evaluate the fiber-degradation and endothelialization of a modified poly L-lactic acid (PLLA) atrial septal defect (ASD) occluder for a long time in vivo., Methods: A total of 57 New Zealand rabbits were selected to establish the vasculature implantation model, which would be used to characterize the mechanical properties and pathological reaction of PLLA filaments (a raw polymer of ASD occluder). In total, 27 Experimental piglets were used to create the ASD model for the catheter implantation of PLLA ASD occluders. Then, X-ray imaging, transthoracic echocardiography, histopathology, and scanning electron microscope (SEM) were performed in the experimental animals at 3, 6, 12, and 24 months after implantation., Results: In the rabbit models, the fibrocystic grade was 0 and the inflammatory response was grade 2 at 6 months after vasculature implantation of the PLLA filaments. The mass loss of PLLA filaments increased appreciably with the increasing duration of implantation, but their mechanical strength was decreased without broken. In the porcine models, the cardiac gross anatomy showed that all PLLA ASD occluders were stable in the interatrial septum without any vegetation or thrombus formation. At 24 months, the occluders had been embedded into endogenous host tissue nearly. Pathological observations suggested that the occluders degraded gradually without complications at different periods. SEM showed that the occluders were endothelialized completely and essentially became an integral part of the body over time., Conclusion: In the animal model, the modified PLLA ASD occluders exhibited good degradability and endothelialization in this long-term follow-up study., (© 2023.

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., (© 2023.

Introduction: The increasing worldwide number of adults with congenital heart disease (CHD) demands greater attention from health professionals. The purpose of this report is to describe the clinical demographic profile, frequency, and invasive treatment status of adults with CHD in a public reference hospital in northeastern Brazil., Methods: This is a retrospective cross-sectional study including 704 patients attended between August 2016 and August 2020. Data were collected from virtual database., Results: Patients' age varied from 17 to 81 years (mean 32±14; median 27 years); 294 (41.8%) patients were male, and 410 (58,2%) were female; 230 (32,7%) had diagnosis from age 18 and up. Cardiac complexity categories were "simple defects" (134 [19%] patients), "moderate complexity" (503 [71.5%]), and "great complexity" (67 [9.5%]). Atrial septal defect (ASD) was diagnosed in 216 (30.7%) patients, ventricular septal defect (VSD) in 101 (14.3%), tetralogy of Fallot in 93 (13.2%), and other CHD in 294 (41.8%). New York Heart Association (NYHA) functional classes were I (401 [57%]), II (203 [28.8%]), III (76 [10.8%]), and IV (24 [3.4%]). Complications were arrhythmias (173 [24%]) and severe pulmonary hypertension (69 [9.8%]). Invasive treatments were corrective surgery (364 (51.6%]), reoperation (28 [4.0%]), palliation (11 [1.6%]), interventional catheterization (12 [1.7%]), surgery plus interventional catheterization (5 [0.7%]), and preoperation (91 [12.9%]). Treatment was not required in 102 (14,5%) patients, and 91 (12.9%) were inoperable., Conclusion: The leading diagnosis was ASD. Frequency of unrepaired patients was high, mainly ASD, due to late diagnosis, which favored complications and denotes a matter of great concern.

Patients who underwent transcatheter edge-to-edge repair (TEER) or transcatheter mitral valve replacement (TMVR) have a transeptal access created by an iatrogenic atrial septal defect (ASD) which leads to significant complications requiring closure. Given limited data, we used the National Inpatient Sample between 2015 and 2020 to evaluate the clinical outcomes of percutaneous closure of ASD (PC-ASD) in TEER/TMVR hospitalizations. A total of 44,065 eligible weighted hospitalizations with either TEER (n = 39,625, 89.9%) or TMVR (n = 4,440, 10.1%) with a higher rate of PC-ASD in the TMVR group (10.7% vs 2.0%, p <0.01). The TEER with PC-ASD group were more likely to experience acute heart failure and right ventricular failure and had longer hospital stays but there was no difference in in-hospital mortality compared with the no PC-ASD group. In the TMVR group, there was no difference in the odds of acute heart failure, right ventricular failure, cardiogenic shock, or acute hypoxic respiratory failure, but the odds of mechanical circulatory support, in-hospital mortality, and length of stay were significantly higher in patients with PC-ASD in the TMVR group. In conclusion, rates of percutaneous closure of ASD after TEER were lower than after TMVR and associated with worse in-hospital mortality in TMVR but not in TEER. Further prospective clinical trials are needed to identify patients who would benefit from the closure of iatrogenic ASD., Competing Interests: Declaration of Competing Interest The authors have no competing interests to declare., (Copyright © 2023 Elsevier Inc.

Catheter ablation (CA) of left atrial tachycardia adjacent to implanted septal closure devices represents a multifaceted challenge. We describe the case of a 57-year-old patient with remote percutaneous closure of atrial septal defect who underwent successful CA of left atrial tachycardia adjacent to the septal device using a transaortic approach and RF energy. Besides the technical difficulties and associated risks, interference between the device and applied RF parameters may limit ablation efficiency. Further research is required to evaluate the safety, efficacy, and optimal energy type/parameters when ablating arrhythmias adjacent to these devices., (© 2023 Wiley Periodicals LLC.)

Device closure has become the preferred procedure for treating oval fossa defects in the last two decades. More recently, transcatheter sinus venosus defect (SVD) closure has emerged as an alternative to surgery. Transcatheter stenting aims to overcome potential late surgical complications such as stenosis of the superior vena cava (SVC) and right upper pulmonary vein (RUPV), as well as sinus node dysfunction. Balloon interrogation of the cavoatrial junction is able to identify patients who are suitable candidates for nonsurgical closure. Successful closure is possible when the balloon seals the SVD and redirects the RUPV towards the left atrium. Oval fossa (secundum) defects can coexist in approximately 9-16% of patients with SVD. Among a group of 80 patients who underwent transcatheter closure of SVD, five adult patients aged between 22 and 52 years also required device closure of an associated oval fossa defect. The procedure involved simultaneous balloon interrogation of both the SVD and oval fossa defect, with continuous monitoring of the RUPV using bilateral femoral venous sheaths. Covered stent exclusion of the SVD was performed with concurrent device closure of the oval fossa defect using 12-36 mm atrial septal occluders. During the procedure, two patients required protective balloon inflation in the RUPV while expanding the covered stent. In one patient, a higher small accessory RUPV was intentionally left to drain into the SVC through the struts of a bare stent anchoring the covered stent in the upper SVC. In another patient, a second overlapping covered stent was used to address residual flows from a fabric tear that became apparent after balloon deflation. There were no vascular complications and only one patient exhibited an insignificant 6 mm residual flow from the caudal edge of the SVD during a follow-up of 5 to 72 months. In conclusion, the closure of both SVD and associated oval fossa defects can be successfully performed in a single procedure, with comparable procedural times and favourable mid-term outcomes., (© 2023.

Background: Atrial septal defects (ASDs) are a common congenital heart defect. This study aimed to determine whether patients diagnosed with ASDs undergoing total joint arthroplasty have differences in 1) medical complications, 2) readmissions, 3) lengths of stay (LOS), and 4) costs., Methods: Using an administrative claims data set, a retrospective query from 2010 to 2020 was performed. The ASD patients were 1:5 ratio matched with controls, yielding a total of 45,695 total knee arthroplasty (TKA) (ASD = 7,635, control = 38,060) and 18,407 total hip arthroplasty (THA) (ASD = 3,084, control = 15,323) patients. Outcomes included medical complications, readmissions, LOS, and costs. Logistical regressions were used to calculate odds ratios (ORs) and P values. P values < 0.001 were significant., Results: The ASD patients had higher odds of medical complications after TKA (38.8 versus 21.0%; OR 2.09; P < .001) and THA (45.2 versus 23.5%; OR 2.1; P < .001), noticeably deep vein thromboses, strokes, and other thromboembolic complications. The ASD patients were not significantly more likely to be readmitted after TKA (5.3 versus 4.7%; OR 1.13; P = .033) or THA (6.0 versus 5.7%; OR 1.05; P = .531). Patient LOS was not significantly greater in ASD patients undergoing TKA (3.2 versus 3.2 days; P = .805) but was greater after THA (5.3 versus 3.76 days; P < .001). Same-day surgery costs were not significantly increased in ASD patients after TKA ($23,892.53 versus $23,453.40; P = .066) but were after THA ($23,981.93 versus $23,579.18; P < .001). Costs within 90 days were similar between cohorts., Conclusion: The ASD patients have greater 90-day complications following primary total joint arthroplasty. Providers may consider preoperative cardiac clearance or adjusting anticoagulation in this population to mitigate these risks., Level of Evidence: III., (Copyright © 2023 Elsevier Inc.

Purpose of Review: The goal of this paper is to review currently available devices for closure of atrial septal defects (ASDs) and ventricular septal defects (VSDs)., Recent Findings: Favorable results from the ASSURED trial resulted in FDA approval for the most recently developed device for transcatheter ASD closure in the United States. Further studies are required to assist in the development or approval of safe devices for transcatheter perimembranous VSD closure in pediatric patients. Device closure is the less invasive and preferred management option for many ASDs, with multiple studies demonstrating lower complication rates, shorter hospital stays, and lower mortality than surgical repair. Complex ASDs that make device closure more difficult include large defects, rim deficiencies, fenestrated defects, multiple defects, and the presence of pulmonary arterial hypertension. Device closure has also become an accepted alternative to surgery for some types of ventricular septal defects VSDs, though challenges and limitations remain. Future innovations including novel devices and techniques are needed to further expand on the types of defects that can be safely closed via transcatheter approach., (© 2023.

Objectives: The aim of this study is to establish a guidance for device retrieval based on comprehensive bench tests., Background: Device embolisation remains a major complication in transcatheter closure of atrial septal defect and patent ductus arteriosus. Although percutaneous retrieval is feasible in the majority of cases, surgical retrieval may be required in complicated circumstances. However, the methods of transcatheter device retrieval have not been completely established., Methods: Bench tests of device retrieval were performed to verify the appropriate retrieval method according to device type/size. The devices used for testing were Amplatzer Septal Occluder (Abbott, Chicago, IL, United States of America), Figulla Flex II (Occlutech GmbH, Jena, Germany), Amplatzer Duct Occluder-I (Abbott), Amplatzer Duct Occluder-II (Abbott), and Amplatzer Vascular Plug-II (Abbott). The retrieval equipment constituted diagnostic catheters (multipurpose catheter and right Judkins catheter, 4-Fr or 5-Fr, Gadelius Medical, Tokyo, Japan), delivery sheath and cables for each device, Amplatz goose neck snares (Medtronic, Minneapolis, MN, United States of America), OSYPKA CATCHER (Osypka ag, Rheinfelden-Herten, Germany), and OSYPKA LASSOS (Osypka). We investigated the retrieval equipment and sheath sizes required for a successful retrieval procedure for variously sized devices., Results: For patent ductus arteriosus devices, the type of snare and the snaring position are considered important. For atrial septal defect devices, simple snare capture or a double-snare technique with a sufficiently large sheath is effective. Special care should be taken when using the OSYPKA CATCHER for device retrieval., Conclusions: The results of this study may assist in the selection of both capture devices and a retrieval sheath or a catheter for complete retrieval.

Re-expansion pulmonary edema is a serious complication that can occur after minimally invasive cardiac surgery through a right mini-thoracotomy. Herein, we describe two paediatric cases where re-expansion pulmonary edema was observed after simple atrial septal defect closure through a right mini-thoracotomy. This is the first case report of re-expansion pulmonary edema after a paediatric cardiac surgery.

A 16-year-old male with past medical history of congenital atrial septal defect surgical repair, presented with recurrent pericarditis secondary to post-cardiotomy injury syndrome (PCIS), After failing medical therapy, he ultimately underwent pericardiectomy for symptom resolution, PCIS is underdiagnosed in children and should be considered in patients with recurrent chest, pain., (© 2023 Wiley Periodicals LLC.)

Congenitally corrected transposition of great arteries is a rare anomaly which are responsible for 0.5% of all CHDs and can be associated with other congenital cardiac abnormalities. Association of congenitally corrected transposition of great arteries and isolated atrial septal defect is a very rare condition, and management of this association is challenging. In this paper, we describe three patients with congenitally corrected transposition of great arteries and isolated atrial septal defect who were admitted to our clinic and all of them underwent percutaneous closure of defect. From 2017 to 2020, we visited three patients with congenitally corrected transposition of great arteries and isolated atrial septal defect. Our patients' ages ranged from 28 to 38 years. All of them underwent percutaneous atrial septal defect device closure without any complications. Patients were discharged from hospital in good condition with a daily dose of Aspirin 80 mg and Plavix 75 mg. For all of them, follow-up echocardiography was performed the day after the procedure at 1, 3, and 6 months later and showed the function of the right-sided left ventricle improvement and the severity of the mitral regurgitation was reduced. Furthermore, clinical evaluation also indicated functional class improvement. Although the cases of percutaneous transcatheter closure are few and cannot be regarded as strong evidence to recommend this procedure, the outcomes are promising and can demonstrate that this approach is practical.

Transcatheter device closure has emerged as the preferred treatment for ostium secundum atrial septal defects with adequate margins, occasionally requiring surgical intervention to manage complications. We report a case of a young female patient who presented with systemic desaturation and exertional dyspnoea 5 years after device closure. Evaluation demonstrated anterior malposition of the septal occluder, with the right atrial rim of the device diverting the blood from the inferior vena cava to the left atrium. She underwent surgical extraction of the device and pericardial patch closure of the atrial septal defect.

So as to produce totally anomalous systemic venous connection, all of the systemic venous tributaries, along with the coronary sinus, should be connected with the morphologically left atrium. Previous descriptions of this rare constellation of anomalous connections of the systemic venous tributaries of the heart have been compromised by the inclusion of individuals having isomeric atrial appendages. In these settings, most frequently, the totally, or almost totally, anomalous systemic venous connections are associated with a sinus venosus defect. It is the anomalous pulmonary venous connections that then create a venovenous bridge, which permits the systemic venous tributaries to drain into the morphologically left atrium, even though they may be predominantly connected to the right atrium. More rarely, it is feasible for the primary atrial septum to develop so as to leave the systemic venous sinus in direct connection with the body of the morphologically left, rather than the morphologically right, atrium. We report a series of patients potentially falling into the category of anomalous systemic venous connections. The findings show a spectrum from partially to totally anomalous connections, with some better interpreted on the basis of anomalous drainage. Included in our cases, nonetheless, is an autopsied example of totally anomalous systemic venous connection produced by an abnormal location of the primary atrial septum. We discuss the potential morphogenesis for this finding. We emphasize the distinction that needs to be made between anomalous systemic venous connections and anomalous systemic venous drainage.

Cerebrovascular embolic strokes are responsible for significant morbidity. 40% of strokes have no inciting cause and are thought to be the result of paradoxical emboli (PDE) passing into the arterial system by way of intra-cardiac or pulmonary vascular defects. We present two cases of PDE resulting in acute ischemic events. A 63-year-old female presented for evaluation of left upper extremity numbness. Imaging was significant for an acute right middle cerebral artery infarct and evidence of a large saddle pulmonary embolism. The patient's stroke was postulated to have been secondary to a patent foramen ovale (PFO). An 87-year-old male presented for evaluation of chest pain. The patient underwent three-vessel CABG and experienced an acute left hemispheric stroke post-operatively. Transthoracic echocardiogram demonstrated a biatrial thrombus transversing a PFO and was postulated to have been the cause. The prompt diagnosis of PDE is paramount to preventing the morbidity associated with repeat ischemic events.

Warden procedure is a popular technique for repairing partial anomalous pulmonary venous connection. We describe a modification of this technique for surgical repair of this condition by raising both a superior vena cava (SVC) flap and right atrial appendage flap to create a tension-free SVC-RA continuity (neo-SVC). The anomalous pulmonary veins are routed via the remanent of proximal SVC and baffled to the left atrium across a surgically created or enlarged atrial septal defect using autologous pericardium.

Background: Residual shunt after closure of an inferior sinus venosus defect (ISVD) is a rare complication with a high rate of reintervention., Case Presentation: Here, we report a rare case of a recurrent defect identified 22 years after closure of an ISVD. The defect (25 × 10 mm) was located at the inferior vena cava-right atrial junction and was closed directly when the patient was 5 years of age. No residual shunt was detected and follow-up was discontinued at age 12 years. However, a residual atrial septal defect shunt was detected incidentally at age 27 years. During the second surgery, the lower end of the original defect was opened and then closed with an expanded polytetrafluoroethylene patch., Conclusions: Because of the high rate of reintervention for residual shunt after ISVD closure, patch closure was selected as a better option to reduce tension at the inferior-posterior border. Patients with this profile should be followed closely, at least during childhood, including by echocardiography.

Infective endocarditis (IE) associated with an ASD device, particularly in the early post-procedure period, is extremely rare.

A 60-year-old woman was admitted to our institution for exertional dyspnea. Transthoracic echocardiography revealed a 1.6 cm secundum atrial septal defect( ASD) and a 4.2×3.1 cm mobile left atrial mass originating from the ASD. The tumor migrated to the mitral valve during diastole and to the atrial septal defect during systole. A totally endoscopic approach via a small right thoracotomy was adopted to resect the mass and close the ASD with a Hemashield patch. Histopathologic examination of the excised mass was consistent with myxoma. The postoperative course was uneventful. A 2-year follow-up revealed no recurrence of the myxoma and ASD.

Background: Partial anomalous pulmonary venous return with intact atrial septum warrants greater understanding and evaluation in the literature., Methods: From January 1993 to December 2018, 293 patients with partial anomalous pulmonary venous return underwent surgical repair. Of these, 45 patients (15.3%) had an intact atrial septum. The median age was 36 years (interquartile range, 24-48). Direct reimplantation was used in 17 patients (38%), intracardiac baffling in 15 (33%), and caval division (Warden) technique in 13 (29%). Descriptive statistics were used to assess the data, and Kaplan-Meier analysis was used to assess survival., Results: Anomalous veins were right-sided in 27 patients (60%), left-sided in 16 patients (36%), and bilateral in 2 patients (4%). The insertion sites were the superior vena cava in 23 patients (51%), innominate vein in 12 (27%), inferior vena cava in 6 (13%), coronary sinus in 2 (4%), right atrium in 1 patient (2%), and unknown in 1 patient (2%). Scimitar syndrome was noted in 8 patients (18%). There was no postoperative mortality or residual defects. Postoperative echocardiography excluded any obstruction of pulmonary or systemic veins. Postoperative complications included atrial fibrillation in 9 patients (20%) and pneumothorax requiring chest tube in 5 patients (11%). Survival at 1, 5, and 10 years was 100%, 95%, and 95%, respectively. Two patients underwent pulmonary vein dilation, one at 3 years and the other at 7 years., Conclusions: Surgical repair of partial anomalous pulmonary venous connection with intact atrial septum can be performed with excellent early and midterm outcomes. The overall incidence of midterm systemic or pulmonary vein stenosis is low., (Copyright © 2023 The Society of Thoracic Surgeons. Published by Elsevier Inc. All rights reserved.)

Objective: Minimally invasive cardiac surgery has not been widely applied in repairing sinus venosus atrial septal defect (SV-ASD). Most were minithoracotomy using the single-patch technique for patients with anomalous pulmonary veins (APVs) connecting to the superior vena cava-right atrium (SVC-RA) junction. It is unclear whether patients with APVs draining high to the SVC can be repaired safely and effectively through port access., Methods: From May 2019 to October 2022, 11 consecutive SV-ASD patients with APVs connecting high to the SVC were enrolled in this prospective study. One 12 mm port and 2 trocars (5.5 mm and 10 mm) were established. The pleural and pericardial spaces were filled with CO 2 . The SVC was snared just below the azygos vein. The RA incision was longitudinally extended along the SVC-RA junction to the SVC. The bovine pericardial patches were used to redirect the APV flow to the left atrium through the ASD and to enlarge the SVC and the SVC-RA junction., Results: There were no early or late deaths and no reoperations. The concomitant procedures included 5 patients (45.5%) with patent foramen ovale closure, 2 with ASD extension, and 3 with tricuspid valve repair. No endoscopic failure was recorded. The average cardiopulmonary bypass and operative times were 96 (23) min and 190 (30) min, respectively. No cases of venous stenosis or sinus node dysfunction were noted during follow-up of 16.4 ± 12.2 months., Conclusions: SV-ASD with the APVs draining high to the SVC could be repaired safely and effectively through port access with a double-patch technique.

The primum atrial septal defect suture line adjacent to the crux is performed carefully with various techniques to avoid atrioventricular block in repair of complete atrioventricular septal defect. We describe our technical modification to simplify the shallow suture line only into the endocardium above the atrioventricular node without conduction disturbance., (© 2022.

We report a rare case of pelvic hematoma caused by iatrogenic external iliac artery hemorrhage following transfemoral venipuncture for atrial septal defect closure. By means of urgent femoral arteriography, bleeding in the branches of the external iliac artery was confirmed and occlusion of the bleeding branches was performed, thus avoiding the need for surgical laparotomy. The patient recovered well, and the hematoma significantly was reduced 2 months after surgery.

Background: Percutaneous device closure of atrial septal defect (ASD) has become an increasingly popular procedure as it offers several advantages. However, it is associated with infrequent, but life-threatening complications such as device embolization., Objective: To analyze the risk factors, common sites of embolization, associated complications, timing of embolization, and the treatment executed., Settings and Design: A retrospective study was performed at a tertiary referral center for cardiac services., Material and Methods: Pre-procedure, intra-procedure, and post-procedure data of patients whose ASD device embolized was collected retrospectively and analyzed for risk factors, common sites of embolization, associated complications, timing of embolization, and the treatment executed. Results: Thirty devices were embolized, out of which 13 were retrieved percutaneously in the Catheter laboratory, whereas 17 patients underwent surgery. Fourteen patients had an unfavorable septal morphology for device closure. Ten devices were embolized in the catheter laboratory, five in the intensive care unit, and two in the ward. The devices were embolized to almost all chambers of the heart and great vessels. One patient had an inferior vena cava rim tear while attempting percutaneous retrieval. One patient required a short period of total circulatory arrest (TCA) for retrieval of the device from ascending aorta, while another required a lateral position for retrieval from descending aorta. One patient required re-exploration for bleeding, while another had an air embolism and succumbed., Conclusions: Once embolization occurs, the risks associated increase manifold. Most of the surgical extractions are uneventful; however, there could be certain complications that may need repair of valvular apparatus, the institution of TCA, or the need for the lateral position. Air embolization though very rare can occur which could be fatal.

We report a case of a 6-year-old boy who developed intra-atrial re-entrant tachycardia after percutaneous atrial septal defect closure. Ablation was performed, and the circuit of tachycardia was identified. This was a rare complication caused by right atrial enlargement due to an atrial septal defect closure device.
