Surgical closure of atrial septal defects

Percutaneous atrial septal defect closure in limited-resource setting: a decade-long experience from Ethiopia

Introduction

Secundum Atrial septal defect (ASD) is the most common type of ASD. When it is large and hemodynamically significant, it can cause symptoms such as dyspnea, exercise intolerance, and palpitations. Following diagnosis confirmation, an ASD with hemodynamic significance should be closed electively. Percutaneous closure (PC) is an effective treatment option for ostium secundum ASD with adequate rims, despite the potential for several complications. This is the first study in Ethiopia and sub-Saharan Africa to report on percutaneous closure of secundum atrial septal defects (ASD) in children, adolescents, and adults. The study assessed the clinical characteristics, immediate and in-hospital outcomes, and complication rates following PC of secundum ASD.

Methodology

his follow-up study, conducted between October 2023 and January 2024, involved 99 patients who underwent percutaneous closure (PC) of ASD at the Cardiac Center of Ethiopia between January 2013 and January 2023. The patients were divided into two groups based on age: Group 1 included children and adolescents (≤18 years of age; n = 42), while Group 2 consisted of adults (>18 years of age; n = 57), at the time of device percutaneous closure. The median and interquartile range was used to describe continuous variables. The absolute frequency and percentages were used to describe the categorical variables. The data were shown using tables and graphs. Baseline characteristics of patients of ≤18 years vs. >18 years were compared using the Mann-Whitney U-test for continuous variables and the Chi-square or Fisher exact test for categorical data.

Results

There was a female predominance with female to male ratio of 1.3. Compared to Group 1 (children and adolescents of age ≤ 18 years), more patients in Group 2(adults of age > 18 years) experienced symptoms (p-value < 0.001). The most common symptoms in adults were easy fatigability and dyspnea (63.2% of adult patients), while the most common symptom in children was recurrent respiratory tract infections (23.8%). Patients in Group 2 had greater pulmonary artery systolic pressure than those in Group 1 (p-value < 0.001). Overall, 88.9% of patients attained immediate success; there was no statistically significant difference between the two groups in immediate success rate (p = 0.52; Group 1 85.7% vs. Group 2 91.2%). Overall, patients' median length of hospital stay was 2 days (IQR, 2-2.5 days). There was no statistically significant difference between the two groups' median hospital stays [Group 1: 2 (IQR, 2-2.5) and Group 2: 2.5 (IQR 2-2.5); P-value = 0.111]. 23.2% of patients experienced complications, with no significant difference between the two groups (Group 1 28.6% and Group 2 19.3%, p = 0.28). The most common complications for patients in Groups 1 and 2 were atrioventricular (AV) valve encroachment (4.8) and paroxysmal supraventricular tachycardia (SVT) (5.3%), respectively. The major complication rates in the two groups did not show a statistically significant difference. Group 1 had a rate of 4.8%, whereas Group 2 had a rate of 0% (p-value = 0.18). The length of stays significantly increased in both groups in the presence of complications (p-value < 0.001).

Conclusion

This study emphasized that Percutaneous Closure of ASD can be successfully performed in resource-limited settings with a high immediate success rate and minimal complications such as AV valve encroachment and paroxysmal SVT. Given that complications impact length of hospital stays, preventing them is crucial.

Genetic Insights into Congenital Cardiac Septal Defects-A Narrative Review

Congenital heart diseases (CHDs) are a group of complex diseases characterized by structural and functional malformations during development in the human heart; they represent an important problem for public health worldwide. Within these malformations, septal defects such as ventricular (VSD) and atrial septal defects (ASD) are the most common forms of CHDs. Studies have reported that CHDs are the result of genetic and environmental factors. Here, we review and summarize the role of genetics involved in cardiogenesis and congenital cardiac septal defects. Moreover, treatment regarding these congenital cardiac septal defects is also addressed.

Surgical Treatment of Atrial Septal Defects

Atrial septal defects (ASDs) are among the most prevalent congenital cardiac malformations. Closure of the defect and repair of associated cardiac malformations are typically indicated if an ASD is hemodynamically significant or symptomatic. This narrative review aims to summarize key aspects of surgical ASD closures. A non-systematic literature review was conducted to cover surgically relevant aspects of (developmental) anatomy, morphology, and treatment. ASDs result from diverse developmental alterations, leading to subtype-specific associated cardiac malformations, meaning surgical therapy varies accordingly. Presently, surgical repair yields excellent outcomes for all ASD subtypes, with minimally invasive approaches, especially in adults, increasingly employed for ASD closure. Surgical ASD repair is safe with excellent results. However, familiarity with ASD subtypes and typically associated lesions is crucial for optimal patient management.

A 24-Year-Old Male Patient With an Ostium Secundum Complex Atrial Defect Secondary to a Perforated Aneurysm With Inferior Vena Cava Agenesis

The article describes a successful clinical outcome in the case of a 24-year-old male with a diagnosis of an ostium secundum atrial defect secondary to a perforated aneurysm associated with vena cava agenesis. During hospitalization, an echocardiogram revealed the presence of ostium secundum inter-atrial communication with a left to right shunt, a left ventricular ejection fraction (LVEF) of 60%, and mild pulmonary hypertension, measured at 40 mmHg. CT imaging showed anomalous dilation of the azygos vein (16.8 mm), associated with interruption of the vena cava in the intrahepatic and adrenal portion, continuing through the azygos system and draining into the superior vena cava. Open-heart surgery was performed with pericardium patch placement on the defect. Postoperative transthoracic echocardiography revealed a tracking of the interatrial septum, with adequate placement of the surgical patch and no evidence of residual short circuits. The postoperative recovery was favorable, and the patient was discharged five days after surgery. Outpatient monitoring at the first and third months showed no complications during physical examination and echocardiogram imaging.

Surgical Repair of Atrial Septal Defect in a Patient with 3-Methylcrotonyl-CoA Carboxylase Deficiency

3-Methylcrotonyl-CoA carboxylase (3-MCC) deficiency is a rare autosomal recessive disease of leucine catabolism. 3-MCC deficiency may lead to metabolic decompensation under stress; however, outcomes of elective surgery requiring cardiopulmonary bypass (CPB) are unknown. We report a 4-year-old girl with asymptomatic 3-MCC deficiency and atrial septal defect (ASD) who's undergone surgical ASD repair under CPB. She was otherwise normal developmentally and medically. Although patients with 3-MCC may face metabolic crises, the ASD repair under CPB was uneventful.

Twin pregnancy with sudden heart failure and pulmonary hypertension after atrial septal defect repair: A case report

BACKGROUND

Pulmonary arterial hypertension (PAH) in pregnancy is one of the major obstetric complications and is considered a contraindication to pregnancy as it is classified as a class IV risk in the revised risk classification of pregnancy by the World Health Organisation. Pregnancy, with its adaptive and expectant mechanical and hormonal changes, negatively affects the cardiopulmonary circulation in pregnant women. Do patients with repaired simple congenital heart disease (CHD) develop other pulmonary and cardiac complications during pregnancy? Can pregnant women with sudden pulmonary hypertension be treated and managed in time? In this paper, we present a case of a 39-year-old woman who underwent cesarean section at 33 wk' gestation and developed PAH secondary to repaired simple CHD. Our research began by a PubMed search for "pulmonary hypertension" and "pregnancy" and "CHD" case reports. Three cases were selected to review PAH in pregnancy after correction of CHD defects. These studies were reviewed, coupled with our own clinical experience.

CASE SUMMARY

Herein, a case involving a woman who underwent atrial septal defect repair at the age of 34, became pregnant five years later, and had a sudden onset of PAH and right heart failure secondary to symptoms of acute peripheral edema in the third trimester of her pregnancy. As a result, the patient underwent a cesarean section and gave birth to healthy twins. Within three days after cesarean delivery, her cardiac function deteriorated as the pulmonary artery pressure increased. Effective postpartum management, including diuresis, significant oxygen uptake, vasodilators, capacity and anticoagulants management, led to improvements in cardiac function and oxygenation. The patient was discharged from hospital with a stable recovery and transferred to local hospitals for further PAH treatment.

CONCLUSION

This case served as a reminder to obstetricians of the importance of pregnancy after repair of CHD. It is crucial for patients with CHD to receive early correction. It suggests doctors should not ignore edema of twin pregnancy. Also, it provides a reference for the further standardization of antenatal, intrapartum and postpartum management for patients with CHD worldwide.

Transcatheter Closure of Superior Sinus Venosus 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.

Case report: A unique quadruple coexisting anomaly-scimitar syndrome, atrial septal defect, vascular ring, and pulmonary sequestration

The article describes a successful clinical outcome in the case of a 5-month old female with a diagnosis of incomplete vascular ring of aberrant right subclavian artery and ostium secundum atrial septal defect associated with partial anomalous pulmonary venous return of scimitar syndrome type, coexisting with right pulmonary sequestration. During hospitalization, surgical correction of the heart defect and resection of the lung sequestration were performed. To the best of our knowledge, described constellation of defects is a unique phenomenon, posing a challenge for complex treatment and disease management.

Transcatheter Closure of Atrial Septal Defect: A Review of Currently Used Devices

Over the past seven decades, significant advancements and innovations have occurred in the field of percutaneous atrial septal defect (ASD) closure using transcatheter-based devices. This article focuses on the current literature surrounding the three Food and Drug Administration (FDA)-approved devices for ASD and patent foramen ovale (PFO) closure in the United States, namely, the Amplatzer Septal Occluder (ASO), Amplatzer Cribriform Occluder, and Gore Cardioform ASD Occluder. The ASO has been widely used since its FDA approval in 2001. Studies have shown its high success rate in closing ASDs, especially small-sized defects. The RESPECT trial demonstrated that PFO closure using the ASO reduced the risk of recurrent ischemic stroke compared to medical therapy alone. The Closure of Atrial Septal Defects With the Amplatzer Septal Occluder Post-Approval Study (ASD PMS II) evaluated the safety and effectiveness of ASO in a large cohort of patients, reporting a high closure success rate and rare hemodynamic compromise. The Amplatzer Cribriform Occluder is designed for the closure of multifenestrated ASDs and has shown promising results in small-scale studies. It successfully closed the majority of fenestrated ASDs, leading to improved right ventricular diastolic pressure without major complications. The REDUCE trial compared PFO closure using the Gore Helex Septal Occluder and Gore Cardioform Septal Occluder with antiplatelet therapy alone. The study demonstrated that PFO closure significantly reduced the risk of recurrent stroke and brain infarction compared to antiplatelet therapy alone. However, the closure group had a higher incidence of atrial fibrillation or atrial flutter. There is a risk of atrial fibrillation with the use of ASO as well. The FDA-approved Gore Cardioform ASD Occluder showed excellent performance in the ASSURED clinical study. The device achieved high technical success and closure rates, with low rates of serious adverse events and device-related complications. A meta-analysis comparing transcatheter ASD closure with surgical closure revealed that the transcatheter approach had a high success rate, lower rates of adverse events, and shorter hospital stays compared to surgery, without any mortality. Complications associated with transcatheter ASD closure have been reported, including femoral arteriovenous fistulas, device embolization, cardiac erosion, aortic incompetence, and new-onset migraine. However, these complications are relatively rare. In conclusion, transcatheter ASD closure using FDA-approved devices has proven to be safe and effective in the majority of cases. These devices offer excellent closure rates, reduced risk of recurrent stroke, and shorter hospital stays compared to surgery. However, careful patient selection and follow-up are necessary to minimize complications and ensure optimal outcomes.

Minimal-Access Atrial Septal Defect (ASD) Closure

Progress towards the development and adoption of minimally invasive techniques in cardiac surgery has been slower than that seen in other surgical specialties. Congenital heart disease (CHD) patients represent an important population within cardiac disease, of which atrial septal defect (ASD) is one of the most common diagnoses. Management of ASD encompasses a range of minimal-access and minimally invasive approaches, including transcatheter device closure, mini-sternotomy, thoracotomy, video-assisted, endoscopic, and robotic approaches. In this article, we will discuss the pathophysiology of ASD, along with diagnosis, management, and indications for intervention. We will review the current evidence supporting minimally invasive and minimal-access surgical ASD closure in the adult and paediatric patient, highlighting peri-operative considerations and areas for further research.

Never fail to surveil! Transcatheter closure of recurrent atrial septal defect secondary to patch degradation in a young boy

We report a case of a 16-year-old boy with symptomatic recurrent atrial septal defect due to patch degradation of an autologous pericardial patch, done 10 years back. He successfully underwent transcatheter closure of the recurrent defect after meticulous assessment of patch rims for stability.

Midterm postoperative outcomes of different types of surgical reconstruction of sinus venosus atrial septal defects with anomalous pulmonary venous connection: The Results of Prospective Cohort Study

Background and Aims

Sinus venosus atrial septal defects (SVASDs) constitute a substantial part of atrial septal defects and are usually characterized by anomalous pulmonary venous connection (APVC), causing complications like sinus node dysfunction and arrhythmias. Several surgical approaches are used for treating SVASDs in pediatric patients, including single- and two-patch techniques. The study aimed to prospectively evaluate and compare the safety and efficacy of these two methods with different follow-up periods.

Methods

Ten patients aged 1-8 years with SVASDs and partial APVC were enrolled in the study at Bhanubhai and Madhuben Patel Cardiac Centre, Karamsad, India, between December 2018 and October 2021. The single-patch (sandwich-patch) technique was used in two patients, whereas the two-patch (dual-patch) technique with autologous pericardium was used in seven. Safety was assessed as the absence of complications in the follow-up periods of 6 months, 1, and 2 years, whereas efficacy was estimated by the preserved sinus rhythm and the development of arrhythmias. Electrocardiographic and echocardiographic methods were used to evaluate both parameters.

Results

No deaths, reoperations, pulmonary vein, and superior vena cava (SVC) stenosis or phrenic nerve palsy were observed among the 10 patients in the three follow-up periods. Sinus rhythm was arrested in two of the seven patients who underwent two-patch repair, whereas no rhythm disturbances occurred in those who underwent single-patch repair.

Conclusion

Both techniques used in SVASD repair with autologous pericardium proved to cause the smaller rate of complications in midterm postsurgical phase. However, there is a potentially great risk of the development of sinus node malfunction after the application of the two-patch technique. Therefore, methods avoiding sinus node interference are preferred in patients with partial APVC involving SVC.

Minimally Invasive Surgical Repair of a Partial Atrioventricular Canal Defect in a 20-Year-Old Patient-A Case Report and Review of Literature

The association of an ostium primum-type defect with a cleft anterior mitral valve is known in the medical literature as the partial form of an atrioventricular canal. We present a case report about a 20-year-old woman with minimal symptomatology that discovered her pathology on routine echocardiography. Today, surgical operation remains the gold standard in such pathologies, especially mandatory when there is important valvular regurgitation and left-to-right shunt. Currently living in the era of fast and good cosmetic outcomes, minimally invasive and endovascular approaches should be developed and more often practiced. This scientific presentation is the first step in showing our department steps in performing minimally invasive surgeries as a routine.

Multimodality Imaging of Sinus Venosus Atrial Septal Defect: A Challenging Diagnosis in Adults

•

SVASD should be suspected in cases of unexplained RV volume overload.

•

Direct visualization of SVASD with TTE is difficult in adults compared with children.

•

TEE is helpful for diagnosing SVASD and associated pulmonary venous abnormalities.

•

Multimodal imaging techniques offer incremental value in the workup of SVASD.

Complications caused by iatrogenic right-to-left shunt after surgical closure of atrial septal defect: a case report

Background

Atrial septal defect (ASD) is a common congenital heart disease. For this condition, surgical treatment can be required depending on the size and type of ASD. This study included a case of a patient who complained of persistent dyspnoea after the surgical treatment for ASD.

Case summary

A 16-year-old girl who underwent a surgical patch closure for ASD at the age of 2 years presented to the emergency department and was diagnosed with acute stroke. Since childhood, she had suffered from exertional dyspnoea due to an unknown cause. Transthoracic echocardiography revealed normal chambers size and function and no signs of right heart strain. Transoesophageal echocardiography (TOE) revealed a misplaced interatrial patch from the previous surgery, which allowed the whole blood to flow from the inferior vena cava (IVC) to the left atrium (LA), creating a large right-to-left shunt that resulted in stroke and heart failure. The patient underwent surgical treatment, and her symptoms improved significantly. Six months later, she was doing well without neurological complications and dyspnoea.

Discussion

This patient experienced stroke at the age of 16 years and had been suffering from heart failure since childhood. A large right-to-left shunt flow from the IVC to the LA by misplaced interatrial patch was found using TOE, right-sided heart catheterization, and inferior caval venography. This diagnosis should be considered in patients complaining of persistent dyspnoea with hypoxia after the surgical repair of ASD.

Atrial septal defect in adulthood: a new paradigm for congenital heart disease

Atrial septal defects (ASDs) represent the most common congenital heart defect diagnosed in adulthood. Although considered a simple defect, challenges in optimal diagnostic and treatment options still exist due to great heterogeneity in terms of anatomy and time-related complications primarily arrhythmias, thromboembolism, right heart failure and, in a subset of patients, pulmonary arterial hypertension (PAH). Atrial septal defects call for tertiary expertise where all options may be considered, namely catheter vs. surgical closure, consideration of pre-closure ablation for patients with atrial tachycardia and suitability for closure or/and targeted therapy for patients with PAH. This review serves to update the clinician on the latest evidence, the nuances of optimal diagnostics, treatment options, and long-term follow-up care for patients with an ASD.

Superior Sinus Venosus Atrial Septal Defect with Partial Anomalous Pulmonary Venous Drainage-Minimally Invasive Approach-Case Report

The atrial septal defect is, after bicuspid aortic valve disease, the most common congenital cardiac disease present in the adult population. The most common atrial septal defects are the ostium secundum type (75–80%), followed by the ostium primum type (15%). The sinus venosus atrial septal defects (SV-ASD), defined as a communication in the posterior part of the interatrial septum, account for about 5 to 10% of atrial septal defects. Approximately 90% of SV-ASDs are associated with partial anomalous pulmonary venous drainage (PAPVD). The minimally invasive approach has gained ground in the treatment of ASDs, especially those of the ostium secundum type. The sinus venosus type is a relatively uncommon form of ASD, which, when associated with a PAPVD, is considered a complex cardiac malformation, and is usually treated in a classical manner, through median sternotomy. We describe the case of a 45-year-old woman diagnosed in adolescence with SV-ASD with PAPVD, who successfully underwent minimally invasive repair with fresh autologous pericardial patch reconstruction through an anterolateral mini-thoracotomy incision. The patient presented with shortness of breath and fatigue after heavy exertions, episodes of paroxysmal nocturnal dyspnea, palpitations during effort and at rest, and had a history of syncope dating from 17 years previously. Echocardiography revealed an SV-ASD with PAPVD in the right atrium and the intraoperative examination discovered that both right pulmonary veins were draining into the superior vena cava.

The Effect of Continuous Field Block through Intercostal Muscles after Atrial Septal Defect Closure via a Mini-Right Thoracotomy in Pediatric Patients

BACKGROUND

Postoperative pain management in thoracotomy patients often is difficult. Furthermore, pediatric patients present more challenges because of their inability to effectively communicate their pain intensity. The purpose of this study was to evaluate the use of continuous field block through intercostal muscles as postoperative pain management in pediatric thoracotomy.

METHODS

Between 2014 and 2018, 11 patients underwent an ASD closure using a cardiopulmonary bypass via a mini-right thoracotomy through the fourth intercostal space. At the time of chest closure, a single-shot field block via the fourth intercostal muscles was performed with levobupivacaine (0.6 mg/kg). The first five patients were only given the single-shot field block (Single group). The remaining six patients were given levobupivacaine continuously (0.1 mg/kg/hr) through an indwelling catheter until the chest tube removal (Continuous group). The groups' vital signs, total amounts of acetaminophen used, postoperative courses were compared.

RESULTS

Although the heart rate did not differ between the groups, the respiratory rate was significantly higher in the Single group versus the Continuous group at 16 and 32 hr post-surgery (35.6 ± 9.7/min vs. 18.5 ± 4.7/min; p=0.007, 43.0 ± 10.4 vs. 25.3 ± 3.1; p=0.042, respectively). The accumulated dosage of acetaminophen given by postoperative day 2 was significantly higher in the Single group versus the Continuous group (55.3 ± 22.1 mg/kg vs. 7.8 ± 17.4 mg/kg; p=0.012).

CONCLUSIONS

Continuous field block via intercostal muscles after ASD closure via a mini-right thoracotomy in children was effective to stabilize the vital signs and reduce the analgesic medication use.

A large congenital atrial septal defect in an adult with delayed therapy

Patients with a large congenital atrial septal defect (ASD) traditionally have the ASD repaired at the preschool age. Unfortunately, insufficient education of patients regarding medical science and clinical recommendations can lead to delayed therapy, resulting in complications during adulthood. We report a rare case of a large congenital ASD in a 20-year-old man. Echocardiography showed a 67-mm ostium secundum defect and moderate mitral and tricuspid regurgitation. The patient underwent transthoracic ASD repair along with mitral and tricuspid valvuloplasty. This report emphasizes the importance of educating patients about congenital malformations and potential interventions in developing countries, particularly in rural communities.

Inferior Vena Cava Obstruction Following Surgical Repair of a Secundum Atrial Septal Defect

Obstruction of the inferior vena cava (IVC) following surgical repair of an atrial septal defect (ASD) is a rare complication. We present the case of a patient who developed IVC obstruction following surgical repair of a large secundum ASD. The diagnostic and management approaches used to care for this patient are discussed. (Level of Difficulty: Intermediate.)

Normalization of the right heart and the preoperative factors that influence the emergence PAH after surgical closure of atrial septal defect

BACKGROUND

Surgical closure of atrial septal defect (ASD) is contraindicated in the condition with severe pulmonary arterial hypertension (PAH), whereas ASD closure in an effective intervention to normalize the structure and function of the right heart after previously experiencing volume overload due to shunting from the defect. This study aimed to evaluate normalization of the right heart and emergence of PAH after surgical closure of ASD.

METHODS

This retrospective study was carried out in 45 patients over 18 years who had undergone surgical closure of ASD. The study has the aim to evaluate the morphological and functional parameters before and after the surgical approach and the preoperative factors that influenced the development of pulmonary arterial hypertension (PAP) after the ASD closure.

RESULTS

The majority of subjects were female (73.3%) although there were no significant differences between males and females from the various parameters. The average of mPAP in the group that experienced PAH was higher than non-PAH group after ASD closure (p = 0.019, 31.23 ± 12.70 mmHg vs 24.07 ± 13.08 mmHg). Significant differences were found in the Right Atrium (RA) dimension, Right Ventricle (RV) dimension, Tricuspid Regurgitation Velocity (TRV) and Tricuspid Annular Plane Systolic Excursion (TAPSE) between before and at 6 months after ASD closure (p = 0.000, p = 0.000, p = 0.000, p = 000, respectively). The sensitivity of the predictive model to estimate PAH at 6 months after surgical closure of ASD was 58%, with a specificity of 62.5%.

CONCLUSION

Structural and functional normalization of the right heart occurs at 6 months after surgical closure of ASD with the decrease of RA and RV dimensions and improvement from tricuspid regurgitation. Emergence of PAH after ASD closure was influenced by higher mPAP before surgical approach.

Undiagnosed inferior vena cava type of sinus venosus atrial septal defect in a middle-aged woman: A rare case report

Sinus venosus atrial septal defect (ASD) accounts for 5% to 10% of ASDs. In contrast with the more common superior vena cava (SVC) type, the inferior vena cava (IVC) type of sinus venosus ASD with overriding IVC is extremely rare. The sinus venosus defect occur posterior to the fossa ovalis and is not regarded as true ASD. Transesophageal echocardiography (TEE) is a diagnostic procedure of choice due to close proximity of atrial septum to TEE transducer. However; it may not constantly yield detailed anatomical and functional characterization, and other imaging modalities such as cardiac magnetic resonance imaging (MRI) may be needed. We report the case of a 45-year-old woman with an undiagnosed hemodynamically significant IVC-type ASD without any anomalous drainage of pulmonary veins, who presented with progressive dyspnea.

Outcome of adult congenital heart disease patients undergoing cardiac surgery: clinical experience of dr. Sardjito hospital

Background

Patients with congenital heart disease require surgery to correct the cardiac defect they had in order to prevent heart failure. Unfortunately, data regarding outcome of adult CHD in Indonesia is still limited. In contrast with developed countries, many congenital heart surgery patients in developing countries are adults. The purpose of this study was to investigate the outcomes of cardiac surgery procedures among adult congenital heart disease patients, and what factors that might influence the outcome of surgery.

Methods

A retrospective study was performed on adult congenital heart disease patients undergoing cardiac surgery at Dr. Sardjito Hospital between April 2018 and March 2019. Variables included in the study were demographic characteristics, laboratory test results, comorbidities, premedication, Cardiopulmonary Bypass (CPB) and ischemia duration were included in the analysis. Outcomes were in-hospital mortality, hospital length of stay, and ICU length of stay.

Results

A total of 25 congenital heart disease patients [19 Atrial Septeal Defect (ASD) patients, and 6 Ventricular Septal Defect (VSD) patients] underwent a cardiac surgery procedure at Dr. Sardjito Hospital during the study period. Mean age was 31 ± 14.92 years. The majority of patients had pulmonary hypertension. During the study period, none of the patients died during postoperative care in the hospital, mean hospital length of stay (LOS) was 8.35 ± 3.39 days and ICU LOS was 26.53 ± 11.33 h.

Conclusion

Surgery in adult patients with congenital heart disease may be successfully performed with low morbidity and mortality.

Efficacy and safety of dacron patch in surgical treatment of congenital disease by echocardiography

To evaluate the efficacy and safety of a new domestic dacron patch in the surgical treatment of congenital heart disease (CHD) with infective endocarditis (IE), a clinical controlled trial is conducted. 48 patients with CHD complicated with IE are selected and randomly divided into two groups. 26 patients in the experimental group are treated with a new domestic dacron patch, while 22 patients in the control group are treated with an imported cardiac polyester patch. By echocardiography, collecting chest X-ray, echocardiography and laboratory examination before and after operation, the residual shunt, cardiac function, liver function, renal function, coagulation function and other related indicators are observed after operation in the two groups, and the therapeutic effect and safety of the new dacron patch are evaluated. The results showed that there is no significant difference in C/T (cardiothoracic ratio), LAD (Left atrial diameter), LVSD (left ventricular end systolic diameter) and LVDD (left ventricular end diastolic diameter) between the two groups before operation, before discharge and 1, 3 and 6 months after discharge (P>0.05). The C/T, LAD and LVDD of the two groups decrease 6 months after operation, and the size of atrioventricle decreases significantly. There is a decreasing trend in the experimental group compared with the control group, but there is no significant difference (P>0.05). There are no significant differences in cardiac function classification, echocardiography, electrocardiogram, patch performance evaluation and blood compatibility between the two groups before operation and 6 months after discharge. CONCLUSION: The new domestic dacron patch has good clinical efficacy and safety.
