Device Closure in Multiple Atrial Septal Defect Secundum Concomitant with Atrial Flutter

This study discusses the case of a 23-year-old male with multiple atrial septal defect (ASD) secundum and atrial flutter who underwent ASD closure using device closure with satisfactory results. The patient recovered successfully and was discharged in good condition. ASD is a congenital heart disease often encountered in adulthood, with various types based on the location of the defect. Device closure of ASDs is one method to address abnormal blood flow, which can also reduce the risk of atrial arrhythmias through a negative remodeling process in the atria and ventricles. ASD closure in cases with multiple ASDs requires special consideration regarding the size, morphology, and distance between defects. Atrial flutter in ASD patients can be resolved with transcatheter ablation. Other studies have shown that device closure of ASDs is associated with a reduced prevalence of atrial tachyarrhythmia in the short to medium term, although atrial flutter/fibrillation and other arrhythmias are common in patients undergoing transcatheter ASD closure. Arrhythmias and conduction disturbances are also associated with ASD.

Hydrops fetalis caused by a complex congenital heart defect with concurrent hypoplasia of pulmonary blood vessels and lungs visualized by micro-CT in a French Bulldog

BackgroundHydrops fetalis (HF) is fluid accumulation in fetus body cavities and subcutaneous tissue. The condition has been described in various farm and companion animal species, including dogs. Most of cases result from a heart defect. Exact nature of this defect is rarely clarified.Case presentationA newborn, male French bulldog puppy with severe HF underwent a full anatomopathological examination to diagnose the primary cause of HF. Based on the anatomopathological examination, fetal ultrasound, and micro-computed tomography, transposition of the great arteries with hypoplasia of the ascending aorta, aortic arch interruption, ostium secundum atrial septal defect, severe tricuspid valve dysplasia, as well as hypoplasia of pulmonary vessels and lungs were diagnosed.ConclusionsThis is the first report of HF caused by severe, complex congenital heart defects with concurrent pulmonary vessel and lung hypoplasia.

Surgical anastomosis of vertical vein to left atrial appendage: A case report of technical aspects

Management of partial anomalous pulmonary venous connection (PAPVC) differs significantly between the defect on the left side, which is adjacent to left atrial appendage, and that on the right one adjacent to the interatrial septum. Here, we report two patients operated at our center. The first case is an adult diagnosed with the left-sided PAPVC draining to an innominate vein through a left-sided vertical vein, and with a large ostium secundum atrial septal defect. The second case is a neonate with mixed-type total anomalous pulmonary venous connection with all right pulmonary veins opening into the coronary sinus, and all the left pulmonary veins connecting to the innominate vein through a left-sided vertical vein. Both patients experienced severe pulmonary arterial hypertension, necessitating surgical treatment involving disconnection of the vertical vein from its junction, or, ligation of the vertical vein-innominate vein junction, coupled with its redirection to the left atrial appendage. We employed different surgical procedures on these patients, given the distinct age difference, intending to anastomose their respective vertical veins to the adjacent left atrial appendage. In this report, the technical aspects of anastomosing vertical vein to left atrial appendage, to avoid pulmonary venous obstruction in these two patients, are discussed.

Managing a Challenge Case: Transesophageal Echocardiography-Guided Transcatheter Closure of a Large Secundum Atrial Septal Defect in a Pregnant Woman

Background: The management of complex cardiovascular conditions during pregnancy poses unique challenges, and in the case of a large secundum atrial septal defect (ASD), achieving successful closure through a transcatheter approach guided by transesophageal echocardiography (TEE) requires careful navigation and expertise. This study sought to present a case that exemplifies the contemporary approach of using TEE guidance for the closure of an ASD in pregnant women Case presentation: A 31-year-old woman with multigravida, diagnosed with secundum ASD and pulmonary hypertension, underwent TEE. The TEE examination revealed a significant ASD measuring 2.8-3.1 cm with inadequate surrounding rims. Subsequently, our intention was to employ a device to address this defect. TEE was utilized to guide the placement of a 14F delivery sheath into the left upper pulmonary vein and left atrium. Using a catheter, we successfully deployed a 40 mm ASD Occluder (MemoPart), concluding the intervention without any complications. Given the concerns regarding the potential risks of radiation exposure and teratogenic effects on fetal development, particularly in young patients and during pregnancy, it is crucial to prioritize TEE-guided closure of ASD for the safety of both the mother and the fetus. Conclusion: Closure of ASD with zero fluoroscopy proved to be a safe and effective procedure, demonstrating feasibility and significant benefits for pregnant women with ASD.

Management of Pregnant Women with Atrial Septal Defect and Pulmonary Hypertension: A Case Report

Background: Pulmonary Hypertension (PH) is a condition where there is an increase in Pulmonary Vascular Resistance (PVR) and an increase in the mean Pulmonary Arterial Pressure (mPAP) to more than 20 mmHg. PH can occur in someone with Congenital Heart Disease (CHD). PH conditions can aggravate pregnancy in women with CHD. Women with PH are recommended not to undergo pregnancy. However, it is possible for women with CHD with PH conditions to undergo pregnancy. In these conditions, optimizing PH therapy is essential so that pregnant women with PH do not experience a worsening of the condition and can carry out their pregnancy well until delivery. Case presentation: A 38-year-old female patient with a history of Atrial Septal Defect-Pulmonary Hypertension came for common control to the cardiac clinic with the pregnancy condition of her 4th child, who was just discovered when she was six months pregnant. Since giving birth to her third child, the patient began complaining of being quickly tired when doing activities accompanied by swollen legs that disappeared with rest. The patient went to a cardiologist for an echocardiography examination and was diagnosed with Atrial Septal Defect (ASD)-Pulmonary Hypertension (PH). Since then, the patient has been routinely treated by a cardiologist with Pulmonary Hypertension drugs, including Phospodiesterase5 (PDE5) inhibitors (Sildenafil) and Prostacyclin Analogue (Dorner). The patient had done Transesophageal Echocardiography (TEE) with the results of ASD secundum suitable for closure by the device. Patients with Right Heart Catheterization (RHC) results, ASD secundum with PH High Flow High Resistance reactive to Vasoreactivity Test. Since the patient was found to be pregnant, the patient continued to use Sildenafil and discontinued the use of Dorner. The patient then continued treatment in a multidisciplinary team. Conclusion: Management of pregnant women with CHD and PH is essential because the condition of PH itself further aggravates the condition of pregnancy. Medical management for PH in pregnant women follows the guidelines for the safety of drugs in pregnancy so that the choice of therapy is crucially related to the goal of treatment to control the PH condition in the patient but still pay attention to safety in pregnancy conditions.

Recognizing Total Anomalous Pulmonary Venous Drainage (TAPVD) from Natural History to the Supportive Imaging Modalities

Congenital Heart Disease (CHD) prevalence was 8 until 9 for each thousand live births, and among all of the CHD, there is in one of condition that involved the malformation of the venous system that called Total Anomalous Pulmonary Venous Drainage (TAPVD). TAPVD can be found and to be diagnosed in all ages, not only in the childhood era. Adult individuals with TAPVD are susceptible to being misdiagnosed as having a significant secundum atrial septal defect if the condition is not known or suspected. A systematic history taking, physical examination, and another supportive imaging modalities is needed to ensure this structural anomaly.

Improvement Functional Capacity In Adult After Percutaneous ASD Closure

This case report describes a 24-year-old woman with a secundum atrial septal defect (ASD) who underwent successful percutaneous ASD closure with significant improvement in symptoms and functional capacity. The patient presented with easy fatigue and shortness of breath on exertion for 10 years. Echocardiography revealed a large secundum ASD with moderate to severe tricuspid regurgitation, mild mitral regurgitation, mild pulmonary regurgitation, and dilatation of the right atrium and ventricle. Right heart catheterization confirmed a large left-to-right shunt and pulmonary hypertension. The patient underwent ASD closure with a Figulla Flex II device, resulting in immediate improvement of hemodynamics. Follow-up at 3 and 6 months demonstrated decreased right ventricular size, improved left ventricular function, and increased exercise caapacity. This case highlights the benefits of ASD closure in improving symptoms and cardiac function, even in patients with longstanding right ventricular dilation.

Complications and Efficacies of Surgical Versus Transcatheter Closure for Pediatric Ostium Secundum Atrial Septal Defect: A Meta-Analysis.

The optimal approach for pediatric ostium secundum atrial septal defect (ASD) closure remains uncertain. This study aims to assess complications and efficacies of surgical and transcatheter closures. Systematic search in Medline, Cochrane, and EMBASE databases identified cohort studies until July 2023. Complications, length of hospital stay, and efficacy outcomes were evaluated. Subgroup analyses considered ethnicity, ASD size, age, and rim deficiency involvement. Fourteen cohort studies involving 9695 patients were comprehensively analyzed. Regarding complications, the pediatric patients in the surgery group exhibited higher occurrences of cardiac arrhythmia (odds ratio [OR]: 1.87, 95% confidence interval [CI]: 1.22-2.87, p=0.004), pericardial effusion (OR: 14.80, 95% CI: 6.97-31.43, p<0.00001), and pulmonary complications (OR: 2.58, 95% CI: 1.73-3.85, p<0.00001) compared with those in the transcatheter group. However, no significant difference in fever incidence was observed (OR: 2.57, 95% CI: 0.90-7.34, p=0.08). Furthermore, length of hospital stay was notably shorter in the pediatric transcatheter group (mean difference [MD]: 4.00, 95% CI: 1.71-6.29, p=0.0006). Regarding efficacies, both groups demonstrated similar rates of successful closure (OR: 1.97, 95% CI: 0.56-6.92, p=0.29) and residual shunting (OR: 0.55, 95% CI: 0.17-1.77, p=0.31) in the pediatric cohort. Subgroup analyses revealed that surgical residual shunting was notably lower in the European pediatric population (OR: 0.18, 95% CI: 0.07-0.45, p=0.0002), in cases with ASD size exceeding 15 mm (OR: 0.19, 95% CI: 0.08-0.49, p=0.0006), and in pediatric patients younger than 8 years (OR: 0.33, 95% CI: 0.12-0.92, p=0.03). Interestingly, residual shunting involving complex ASD with rim deficiency was more pronounced in the surgery group (OR: 2.66, 95% CI: 1.33-5.32, p=0.006). Both surgical and transcatheter closures are equally effective, with transcatheter closure showing significantly fewer complications. This meta-analysis offers pivotal insights for clinicians grappling with the optimal approach to pediatric ostium secundum ASD closure. The observed higher incidence of cardiac arrhythmias, pericardial effusions, and pulmonary complications in surgical closures underscores the challenges associated with this modality. In contrast, transcatheter closure, with its comparable efficacy and shorter hospital stays, emerges as an appealing and less invasive alternative. These findings equip clinicians with evidence to make informed decisions, optimizing patient outcomes. Subgroup analyses further refine recommendations, emphasizing tailored considerations for European pediatric patients, larger ASDs, and those under 8 years old, ultimately fostering personalized and improved care strategies.

Transcatheter Closure of Secundum Atrial Septal Defects in Pediatric Patients: A 15-Year Single-Center Experience.

Transcatheter closure is the first-line treatment option for hemodynamically significant secundum atrial septal defects (ASDs). This study examines our center's experience with this procedure over the last 15 years. Pediatric patients aged 0-18 years with secundum ASDs who were planned for transcatheter closure in our clinic between January 2007 and January 2023 were retrospectively evaluated. Transcatheter secundum ASD closure was planned for a total of 334 patients during the study period: 191 girls (57.2%) and 143 boys (42.8%). Their mean age was 8.08±3.9 years, and their mean weight was 30±15.6 kg. Defect diameter measured transesophageally ranged from 5 to 35 mm, with a mean of 12.56±4.02 mm. Transesophageal echocardiographic examination revealed a single secundum ASD in 319 patients (95.5%) and multiple secundum ASDs in 15 patients (4.5%). In 11 patients (3.3%), the procedure was terminated before initiating transcatheter ASD closure because of insufficient vena cava rims or a very large ormulti-fenestrated defect. The 323 patients (96.7%) who underwent transcatheter ASD closure had a mean pulmonary artery pressure of 15.1±4.0 mmHg and a mean Qp/Qs ratio of 1.97±0.56. The procedure failed in four patients (1.3%) because of device embolization (n=2) or the inability to properly position the device (n=2). Major complications other than device embolization observed during or after transcatheter closure included anesthetic-induced respiratory depression (n=1) and total atelectasis of the lung (n=1). No new major complications were detected during the patients' long-term follow-up. With appropriate patient and device selection, transcatheter closure is a safe and effective treatment for secundum ASD and should be the first treatment of choice.

Percutaneous Secundum Atrial Septal Defect Closure: Failure Rate and Procedural Predictors

Background: Percutaneous atrial septal defect (ASD) closure is one of therapeutic options for patients with a suitable ASD anatomy, however in developing countries, the exact figure and procedural characteristics remain unknown. Therefore, this study was conducted to identify the failure rate and procedural predictors of the percutaneous ASD closure.Materials and methods: A retrospective study using a database of all patients undergoing percutaneous ASD closure was conducted between March 2010 to November 2023. Patients who developed a pulmonary hypertensive crisis during the procedure were excluded. Procedural and echocardiographic parameter were measured and analyzed.Results: A total of 112 samples were included in this study, 74.1% were female and 55.36% were pediatric patients. The failure rate was 12.5% (n=14) with diameter index was higher in the failed group. Unpaired T-test revealed that ASD size was one of the predictor failure in pediatric patients (mean diameter: 24.7±6.46 mm vs. 16.36±5.94 mm, p=0.001). There were no statistically significant variations in rim diameters, while compared with all patients with appropriate rims (rim ≥7mm), the failure rate was higher in patients with two rims measuring between 5.9 and 6.9 mm and rims less than 5 mm. Two patients presented with device embolization and required surgical device removal.Conclusion: The failure rate of percutaneous ASD closure was 12.5%. A larger ASD increases the risk of failure of percutaneous closure in pediatric patients. Furthermore, patient with 5-6.9 mm on two or more rims as well as those with rim less than 5 mm, have a higher failure rate.Keywords: secundum atrial septal defect, percutaneous closure, failure rate

Original Article--Clinical and Procedural Characteristics of Successful Transcatheter Device Closure of Ostium Secundum Atrial Septal Defect in Symptomatic Children Weighing

This retrospective study sought to determine the feasibility of transcatheter atrial septal defect device closure in patients less than 15 kg, as well as to assess complication rates and the reasons for unsuccessful device closure. In general, the risks associated with transcatheter atrial septal defect device closure are believed and reported to be relatively low, but the evidence stems from trials involving adults and older children. Current guidelines do not recommend atrial defect closure in device closure in children <15 kg, due to limited data available for feasibility and safety of device closure in this group of patients. Retrospective review of all patients who underwent elective transcatheter closure of ostium secundum atrial septal defect between September 2013 to February 2022. We excluded all children above 15 kg, as well as those with complex congenital heart defects. Major and minor complications were predefined and indications for referral were evaluated. We identified 81 patients meeting criteria with a median procedural age of 3 years (1 year-8 years), and median weight of 12 kg (4-15 kg). Successful device closure was achieved in 95.1% (77/81) and in 4.9% (4/81), the procedure was aborted. There was 1 major (1.2%) and 1 minor (1.2%) complication, total complication rate (2.4%). 100% of the referrals had right heart enlargement and exertional dyspnoea, 18.5% had recurrent lower respiratory tract infection and 9.9% had failure to thrive. Rate of resolution of residual shunt was 95.1%. at post-procedure day 1 and 98.8% at post-procedure 3 and 6 months respectively. Percutaneous atrial septal defect closure can be done effectively and safely in symptomatic children weighing less than 15 kg in experienced centres. However, deferral for closure until the historically established timeline of around 4-5 years of age should be strongly considered in asymptomatic children.

Secundum atrial septal defect closure in adults in the UK.

To examine determinants of access to treatment, outcomes and hospital utilization in patients undergoing secundum atrial septal defect (ASD) closure in adulthood in England and Wales. Large retrospective cohort study of all adult patients undergoing secundum ASD closures in England and Wales between 2000/01 and 2016/17. Data were from population-based official data sets covering congenital heart disease procedures, hospital episodes and death registries.Out of 6541 index closures, 79.4% were transcatheter (median age 47 years, IQR 34-61) and 20.6% were surgical (40 years, 28-52). The study cohort was predominantly female (66%), with socio-ethnic profile similar to the general population.Mortality in hospital was 0.2% and at one year 1.0% (95%CI 0.8%-1.2%). Risk of death was lower for transcatheter repairs, adjusting for age, sex, year of procedure, comorbidities and cardiac risk factors (in-hospital adjusted-OR 0.09, 95%CI 0.02-0.46, one-year adjusted-HR 0.5, 0.3-0.9). There was excess mortality one year after ASD closure compared to matched population data.Median (IQR) peri-procedural length of stay was 1.8 (1.4-2.5) and 7.3 (6.2-9.2) days for transcatheter and surgical closures, respectively. Hospital resource use for cardiac reasons started the year before repair (median 2 inpatient and 2 outpatient-only days) and decreased post-repair (zero inpatient and one outpatient days during the first two years). This national study confirms that ASD closure in adults, by surgical or transcatheter methods, is provided independently of ethnic or socioeconomic differences, it is low (but not no) risk and appears to reduce future cardiac hospitalisation even in older ages.

Device-related thrombosis after transcatheter closure of atrial septal defect using the Gore Cardioform ASD occluder.

A previously healthy 60-year-old female was diagnosed with a secundum atrial septal defect measuring 23 x 12 mm on transesophageal echocardiogram.

Transcatheter closure of atrial septal defect using intracardiac echocardiography: a two-center, retrospective study.

We present the experience and long-term results of intracardiac echocardiography (ICE)-guided closure of ostium secundum atrial septal defects (ASDs) in two Italian centers and investigate its systematic applicability as the gold standard in routine clinical practice. We retrospectively evaluated all consecutive patients who underwent an ASD percutaneous closure procedure from March 2008 to February 2020. All patients underwent a preprocedural transesophageal echocardiography (TEE) evaluation. The closures were carried out under fluoroscopic and ICE guidance. A follow-up visit was performed at 1, 3 and 12 months, followed by telephone evaluations approximately every 2 years. Sixty-six patients (29% male individuals), mean age 43 ± 16 years, were treated. In 15 cases, the TEE defect diameter was less than 10 mm, and in 8 of these patients, the ICE intraprocedural sizing increased the maximum diameter by more than 5 mm. Sizing balloon of the defect was performed in 51 cases; 2 patients received an ASD 38 mm device. Eight patients had multiple defects; in three of these, it was necessary to apply two devices. Four patients showed nonsignificant residual shunt; no complications related to the use of ICE were observed. One patient presented the migration of the ASD device into the abdominal aorta, percutaneously retrieved with a snare. No major complications were recorded during the entire follow-up period. This study confirms that ICE monitoring during ASD percutaneous closure is well tolerated and effective; it might be achievable as a routine gold standard by operators willing to use ICE systematically in all transcatheter closure interventions of interatrial communications.

Risk factors for isolated atrial septal defect secundum morbidity

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.

Natural History of Secundum ASD in Preterm and Term Neonates: A Comparative Study.

Atrial septal defects(ASDs) are common in neonates. Although past studies suggest ASDs ≥ 3mm in term neonates(TNs) are less likely to close, there is paucity of data regarding the natural history in preterm neonates(PNs), information that would inform surveillance. We sought to compare spontaneous closure rates and need for intervention for ASDs in TNs/near term (≥ 36weeks) versus PNs (< 36weeks). We included all TNs and PNs who underwent echocardiography at ≤ 1month between 2010 and 2018 in our institution with an ASD ≥ 3mm, without major congenital heart disease, and with repeat echocardiogram(s). Spontaneous resolution was defined as size diminution to < 3mm or closure. We included 156 TNs (mean gestational age at birth 38.6 ± 1.4weeks) and 156 PNs (29.6 ± 3.7weeks) with a mean age at follow-up of 16 ± 19 and 15 ± 21months, respectively (p = 0.76). Based on maximum color Doppler diameter, in TNs, ASD resolution occurred in 95% of small (3-5mm), 87% of moderate (5.1-8mm), and 60% of large (> 8mm) defects; whereas, in PNs, resolution occurred in 79% of small, 76% of moderate, and 33% of large ASDs. There was a significant association between size and ASD resolution in TNs (p = 0.003), but not PNs (p = 0.17). Overall, ASD resolution rate was higher in TNs (89%) versus PNs (78%) (p = 0.009), and fewer TNs (1%) compared to PNs (7%) required ASD intervention (p = 0.02). Most ASDs identified in TNs and PNs spontaneously resolve. PNs, however, demonstrate lower ASD resolution and higher intervention rates within all size groups. These data should inform follow-up of affected neonates.

A case of ostium secundum atrial septal defect for major decompressive spine surgery – covering the paths still left untreaded

Atrial septal defect (ASD) accounts for 35% of all congenital heart diseases in adults. Patients usually present in their twenties or thirties owing to gradually progressive right ventricular remodeling because of left to right shunt, right-sided heart failure, and pulmonary hypertension. In this case report, we present the management of young female patient with ASD posted for D5 spine decompression and fixation. Patients with congenital heart disease for spine surgery present with unique set of challenges for anesthesiologists. Well-prepared anesthesia plan is essential to prevent increase in shunt fraction, shunt reversal, hypoxia, hypercapnia, acidosis, and hypothermia along with careful addressal of positioning issues to ensure smooth recovery of patient.

Left Atrial Stiffness Increases after Trans-Catheter Atrial Septal Closure.

Transcatheter atrial septal closures for secundum atrial septal defects (ASD) have demonstrated favorable clinical outcomes. However, the impact of device implantation on the stiffness of the left atrium remains unclear. Patients with secundum ASD undergoing transcatheter closure and follow-up right heart catheterization at six months were included. We investigated the relationship between post-procedural (E/e' ratio)/(LAs strain) ratio, an index of left atrial stiffness, and baseline characteristics, including echocardiographic and hemodynamic parameters. Forty patients were included (median 69 (56, 75) years, 12 men, and pulmonary systemic flow ratio 2.27 (1.96, 2.86)). Trans-catheter ASD closure was successfully performed without any major complications, accompanying a significant reduction in right ventricular to left ventricular size ratio from 1.04 (0.87, 1.13) to 0.74 (0.66, 0.86) (p < 0.01). The (E/e' ratio)/(LAs strain) ratio was markedly elevated the day after the procedure and was further increased 6 months later (before: 0.25 (0.17, 0.34), 1 day later: 0.34 (0.27, 0.50), 6 months later: 0.43 (0.27, 0.76), p < 0.01). The groups with higher (E/e' ratio)/(LAs strain) ratios at 6 months had significantly more severe heart failure conditions including lower cardiac output and higher plasma B-type natriuretic peptides. Patients undergoing transcatheter ASD closure experienced improvement in hemodynamics and clinical symptoms but an elevation in left atrial stiffness post-procedure. The clinical ramifications of this finding, particularly during the longer-term observation period subsequent to ASD closure, warrant further investigation.

Echocardiographic Findings of Children with Down Syndrome

Objective: Down syndrome is the most common well-known chromosomal disorder. The incidence of congenital heart disease (CHD) in these patients is high and it is the most important cause of mortality. In this study, we reviewed the comorbid CHDs and their characteristics in patients with the diagnosis of Down syndrome. We compared our results with the results of studies conducted in different regions of our country in different years. Materials and Methods: Between January 2020 and December 2022, data from a total of 385 patients (175 females, 210 males) with Down syndrome were evaluated. The age of the mothers at the time of delivery and the availability of prenatal diagnosis information in accessible patients were determined. Results: Of 385 patients with Down syndrome, 38.2% (n=147) had CHD. Among patients with CHD, 57 patients had atrioventricular septal defect (AVSD) (38.7%), 35 patients had perimembranous ventricular septal defect (23.8%), 24 patients had secundum atrial septal defect (16.3%), 8 patients had patent ductus arteriosus (5.4%), and 10 patients without AVSD had CHD with multiple left-to-right shunts (6.8%). The most common cyanotic CHD was tetralogy of Fallot (n=7, 4.7%). Complete AVSD was present in 63.1% of AVSD patients. CHD was present in 36.2% of boys and 40.6% of girls. Among all female patients, 17.1% had AVSD, while this rate was 12.8% among all male patients (p&lt;0.05). The mean maternal age at delivery was 32.59±6.9 (17-48) years. It was found that children with Down syndrome whose mothers had a maternal age of 33.5 years and above had a lower rate of CHD. Of the 170 mothers for whom prenatal diagnosis information was available, 58.2% (n=99) had a prenatal diagnosis. Conclusion: Prenatal diagnosis opportunities have increased and become widespread over the years. However, no significant change was observed in the rates of CHD, which is most frequently responsible for mortality in children with Down syndrome. It is appropriate for every expectant mother with a prenatal diagnosis to be referred for fetal echocardiography or postnatal transthoracic echocardiography.

The Risk Factors of Mitral Regurgitation Deterioration After Secundum Atrial Septal Defect Closure.

Association between secundum Atrial Septal Defect (ASD) and mitral valve (MV) disease has been recognized for decades. Secundum ASD closure can reduce mitral regurgitation (MR) degree. However, in some patients, deterioration of MR after ASD closure has been observed. We aimed to identify the risk factors of MR deterioration after ASD closure. This was an observational retrospective cohort study. Data were collected from the registry and echocardiogram report. We evaluated all patients with ASD closure by surgery and transcatheterization without MR intervention from January 2012 until June 2021 at Dr. Sardjito General Hospital, Yogyakarta. We excluded patients with multiple ASD and ASD with severe MR requiring MV intervention. Risk factors for MR deterioration were evaluated using multivariate logistic regression. A total of 242 patients who underwent post-secundum ASD closure were included. In multivariate analysis, ASD closure by surgery, large left atrial (LA) diameter (>40 mm), low left ventricular ejection fraction (LVEF; <55%), and MV regurgitation degree were significant risk factors for MR worsening after ASD closure, with OR of 2.103 (95% CI 1.124-3.937); 2.871 (95% CI 1.032-7.985); 5.531 (95% CI 1.368-22.366); and 2.490 (95% CI 1.339-4.630) respectively. ASD closure by surgery, large LA diameter (>40 mm), low LVEF (<55%), and MV regurgitation degree are independent significant risk factors for MR deterioration in post-secundum ASD closure patients. In adult ASD patients with reduced LV function, it is recommended to perform balloon testing and consider fenestrated closure, as low LVEF <55% has the highest risk of causing new or deteriorating MR.
