Abstract
Objects The aim of this study was to investigate the morphologic changes of a novel fully biodegradable implantable device after closing a perimembranous ventricular septal defect (Pm-VSD) and to evaluate the effect of the occluder on the myocardial function in patients during a 3-year follow-up period. Methods One-year, 2-year, and 3-year follow-ups were carried out after implantation with a total of 30 Pm-VSD patients who had successful closure by the fully biodegradable occluder. In total, 30 healthy children were enrolled as controls. At discharge and at every follow-up visit, the lengths of the left and right discs of the novel device were measured in the apical three- and four-chamber as well as short-axis views. At the end of the follow-up, using three-dimensional speckle-tracking conditions, the values of myocardial deformation, including global longitudinal strain, global circumferential strain, and global area strain, were acquired. Results The fully bioabsorbable double-disc occluder gradually decreased over time and was eventually invisible under echocardiographic scanning during the follow-up (p < 0.05). At the end of the third year, there were no significant differences in the myocardial deformation parameters between the cases implanted with the novel devices and the controls; no significant differences were found between the basal segments of the ventricle septa and that of the left ventricle (LV) free wall among the patients who completed the Pm-VSD closure using the fully biodegradable occluder (p > 0.05). Conclusion The novel fully biodegradable occluder is a safe, effective, and perfect alternative for the treatment of VSD. Echocardiography plays a crucial role in the follow-up of this new type of occluder implantation.

Procedural outcomes of percutaneous closure of perimembranous and other ventricular septal defects using Konar-MF occluder and short-term follow-up. Ann Pediatr Cardiol 2024; 17:101-108. [PMID: 39184123 PMCID: PMC11343394 DOI: 10.4103/apc.apc_201_23] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/29/2023] [Revised: 04/24/2024] [Accepted: 04/27/2024] [Indexed: 08/27/2024] Open
Abstract
Introduction The study aims to assess the procedural outcomes and follow-up after transcatheter closure of ventricular septal defects (VSDs) in children utilizing the Konar-MF™ occluder (Lifetech Scientific, Shenzhen, PRC) device. Materials and Methods Clinical features, demographic characteristics, and follow-up findings of children undergoing percutaneous VSD device closure were retrospectively analyzed from the medical records. Results Fifty-seven patients underwent VSD closure using the Konar-MF occluder between January 2019 and April 2023. Median age and body weight of patients were 36 (5-216) months and 12.5 (3.8-42) kg, respectively. The mean size of the defect on the left ventricular side was 6.5 ± 2.4 mm on echocardiography; the mean pulmonary artery pressure was 19.1 ± 9.7 mmHg. Three patients with severe pulmonary hypertension had successful device closure. The most used device size was 8 mm × 6 mm. The initially chosen device was upsized in 4 (7.01%) patients and downsized in 1 (1.7%) patient. Forty-five patients (78.9%) had device closure through the retrograde route. The procedure was successful in 53 (93.0%) patients. Immediate shunt occlusion was achieved in 86.8% of patients. Major complications, namely, embolization (1) and moderate aortic regurgitation (1) in two patients were successfully managed by surgery. One patient with severe tricuspid regurgitation has been on close follow-up. There was no mortality. Late complications such as valve regurgitation or rhythm disturbance were not identified on a median follow-up of 6 (1.5-47) months. Conclusion Transcatheter VSD closure using a Konar-MF occluder device is safe and effective, even in smaller children. The ability to deliver both anterogradely and retrogradely is a unique advantage.

Abstract
Background Congenital heart disease is the most common birth defect and the leading cause of childhood mortality in high-income countries. In these countries, the prognosis for a child born with congenital heart disease is excellent, with over 90% achieving adulthood. However, in the low and lower-middle-income countries, as ours, the outlook is starkly different. In Chiapas, because of the progress of the hemodynamics program, more and more types of congenital heart diseases are susceptible to being treated by cardiac catheterization. Objective To show the global experience of the interventionism in congenital heart diseases in Chiapas from its inception to recent days. Method Through a retrospective study from April 2016 to June 2023, we reviewed the electronic files of the total of patients who underwent cardiac catheterism during the same period of time. Results A total of 1000 procedures were performed, 581 in female patients, with a median age of 4 years (1 day to 77 years). Of the total procedures, 115 (11.5%) were diagnostic catheterizations and 885 (88.5%) were interventional. Conclusions Cardiac catheterization in pediatrics in Chiapas has displaced cardiac surgery in a large percentage, and the results that have been obtained are undoubtedly encouraging, which already represents a decentralization in the care of congenital heart diseases in our country.

Abstract
Background Retrograde closure of perimembranous ventricular septal defects (pmVSDs) is a well-established procedure. However, interventionists are still looking for the best closure device. Methods We performed a single-center retrospective review of 5-year-experience (from July 2015 to July 2020) with retrograde closure of pmVSDs using AmplatzerTM Duct Occluder II (ADOII) and KONAR-MF™ VSD occluder (MFO). Deficient sub-aortic rim (SAR) (≤2.5 mm for MFO and ≤3 mm for ADOII) was an exclusion criterion in defects with a diameter ratio (right-side exit/left-side entry) > 0.5. Results We identified 77 patients (57.1% males) with a median age of 4.3 years (IQR, 2.2-8.3) and a median weight of 16 kg (IQR, 11.2-24.5). 44 (57.1%) defects (22.7% with deficient SARs) with a median left-side defect diameter of 8.7 mm (IQR, 5.7-10) were closed with ADOIIs. 33 (42.9%) defects (51.5% with deficient SARs) with a median left-side defect diameter of 10.8 mm (IQR, 8.8-13.5) were closed with MFOs. One 7/5 MFO was removed before release and upsized to a 12/10 MFO. Implantation success rate was 100% with ADOII and 90.9% with MFO devices. Two MFOs were snare-recaptured after embolization, and one 9/7 MFO was snare-retrieved for a new onset of grade-2 aortic regurgitation that persisted afterward. Median follow-up was 3.3 years (IQR, 2.1-4.2) for ADOII and 2.3 years (IQR, 1.7-2.5) for MFO. No permanent heart block or death occurred. Freedom from left ventricular dilation was 94.62% at 36 months of follow-up. Freedom from residual shunt was 90.62% for MFO and 89.61% for ADOII at 24 months of follow-up. One 2.6-year-old patient with baseline mild aortic valve prolapse and trivial aortic regurgitation developed a grade-2 aortic regurgitation after 9/7 MFO implantation. He was treated surgically after two years without device extraction. One new grade-2 asymptomatic tricuspid regurgitation persisted at the last follow-up in the ADOII group. Conclusions ADOII and MFO are complementary devices for effective retrograde closure of pmVSDs in children, including defects with absent or deficient SAR. ADOII is limited to smaller defects but offers a lower profile and a flexible left-side disk for better maneuverability over the aortic valve during retrograde implantation.

Abstract
INTRODUCTION Ventricular septal defect is the most common congenital heart defect. Surgical repair has been standard therapy for symptomatic ventricular septal defects since the 1950's. Catheter-based device closure of ventricular septal defects emerged in the 1980's and has become a safe and effective alternative in select patients. AREAS COVERED This review focuses on patient selection and procedural techniques for device closure of ventricular septal defects, including percutaneous and hybrid perventricular approaches. The available devices used for these procedures, and outcomes of their use, are reviewed. EXPERT OPINION Percutaneous and perventricular device closure of ventricular septal defects is safe and effective in select patients. However, the majority of ventricular septal defects requiring closure continue to be managed with conventional surgery. Further development and investigation of transcatheter and hybrid surgical approaches for closing ventricular septal defects is required.

Abstract
Ventricular septal defects (VSDs) are the most common kind of congenital heart disease and, if indicated, surgical closure has been accepted as a gold-standard treatment. However, as less-invasive methods are preferred, percutaneous device closure has been developed. After the first VSD closure was performed percutaneously by Lock in 1988, both techniques and devices have developed consistently. A perventricular approach for closure of muscular VSD in small patients and the closure of perimembranous VSD using off-label devices are key remarkable developments. Even though the Amplatzer membranous VSD occluder (Abbott) could not be approved for use due to the high complete atrioventricular conduction block rate, other new devices have shown good results for closure of perimembranous VSDs. However, the transcatheter technique is slightly complicated to perform, and concerns about conduction problems after VSD closure with devices remain. There have been a few reports demonstrating successful closure of subarterial-type VSDs with Amplatzer devices, but long-term issues involving aortic valve damage have not been explored yet. In conclusion, transcatheter VSD closure should be accepted as being as effective and safe as surgery but should only be performed by experienced persons and in specialized institutes because the procedure is complex and requires different techniques. To avoid serious complications, identifying appropriate patient candidates for device closure before the procedure is very important.

Abstract
BACKGROUND Both percutaneous and perventricular device closures of perimembranous ventricular septal defects (Pm-VSDs) are alternatives to surgical procedures,but they all present certain drawbacks. OBJECTIVE To report our clinical experiences and midterm follow-up results of minimally invasive peratrial device closure of Pm-VSDs under the guidance of transesophageal echocardiography(TEE) in patients <12 months of age. METHODS Between January 2015 and December 2020,268 patients <12 months of age with Pm-VSDs underwent peratrial device closure in our institute. The procedure was performed under TEE guidance via a small right subaxillary incision. The delivery pathways is established by manipulating the hollow probe, and then the device is installed. RESULTS A total of 263 cases (98.1%) underwent successful closure, whereas five cases failed and were converted to cardiopulmonary bypass operation via the original incision during the procedure. The mean age was 9.5 ± 2.0 months and the mean body weight was 8.8 ± 1.4 kg. The mean diameter of the VSD was 4.4 ± 0.5 mm. One patient (0.4%) underwent a second thoracotomy for postoperative intercostal hemorrhage on the second day after surgery. The mean diameter of the occluder size was 5.5 ± 0.6 mm. During the follow-up (4.3 ± 1.4 y), there was no mortality, no new aortic valve regurgitation and atrioventricular block. CONCLUSION Peratrial device closure of Pm-VSDs via the right subaxillary route under TEE guidance is safe and effective at midterm follow-up, confirming this is an valuable alternative method for patients <12 months of age.

Abstract
Percutaneous closure of ventricular septal defect (VSD) can effectively occlude abnormal blood flow between ventricles. However, commonly used Nitinol occlusion devices have non-negligible limitations, such as nondegradability leading to life-threatening embolization; limited device size predisposing to displacement and wear; only a few radiopaque markers resulting in inaccurate positioning. Nevertheless, the exploration of customized, biodegradable, and overall radiopaque occluders is still vacant. Here, overall radiopaque, biodegradable, and dynamic reconfigurable 4D printed VSD occluders are developed. Based on wavy bionic structures, various VSD occluders are designed and manufactured to adapt to the position diversity of VSD. The customized configuration, biocompatibility, and biodegradability of the developed 4D printed bionic occluders can eliminate the series of complications caused by traditional occluders. The overall radiopacity of 4D printed VSD occluders is validated ex vivo and in vivo, whereby accurate positioning can be assured. Notably, the preparation strategies for 4D printed occluders are scalable, eliminating the barriers to mass production, and marking a meaningful step in bridging the gap between modeling and clinical application of 4D printed occlusion devices. This work opens attractive perspectives for the rapid manufacturing of customized intelligent medical devices for which overall radiopacity, dynamic reconfigurability, biocompatibility, and biodegradability are sought.

Abstract
Objectives To assess the mid-term safety and efficacy of transthoracic perimembranous ventricular septal defect (Pm-VSD) closure using a new biodegradable device. Implantation entailed right subaxillary minithoracotomy under transesophageal echocardiography guidance. Methods Between October 2019 and January 2020, 13 patients (males, 5; mean age, 3.6 ± 2.5 years) with Pm-VSDs underwent transthoracic device closures at Zhengzhou University Central China Fuwai Hospital as described previously. Delivery pathways were established by manipulating a hollow probe from right atrium through tricuspid valve to right ventricle and then through VSDs to left ventricle, whereupon installation took place. Results All occluder implantations were successfully executed. Mean defect size was 4.1 ± 1.0 mm, and mean device waist size was 5.2 ± 1.1 mm. One patient (7.7%) with 1.5-mm residual shunt showed complete closure at discharge. There was 1 instance of postoperative incomplete right bundle branch block, which converted to complete right bundle branch block at month 1. During patient follow-up (mean, 24.6 ± 0.8 months), no device dislocations, new residual shunts, new valvular regurgitation, or detectable atrioventricular block ensued. Conclusions Closure of Pm-VSDs using a novel, fully biodegradable occluder in the manner described has proven safe and effective at mid-term follow-up. Long-term safety and efficacy of this device must be further corroborated in a large patient cohort going forward.

Abstract
Transcatheter closure of perimembranous ventricular septal defect is an alternative to surgery in selected small to medium defects with a reasonable distance between the defect and the aortic or tricuspid valves. Surgical closure is generally preferred for large defects with an inlet to outlet extension, aortic malalignment, or deficient aortic rim. We report two successful cases of percutaneous closure of large perimembranous ventricular septal defects with inlet to outlet extension using an Amplatzer Vascular Plug-II via a retrograde approach. Transcatheter closure of large perimembranous ventricular septal defect with inlet to outlet extension is feasible and facilitated by the characteristics of the Amplatzer Vascular Plug-II device and the specific implantation technique.

Abstract
BACKGROUND Transcatheter ventricular septal defect closure remains a complex procedure with potential complications like complete heart block and aortic regurgitation. The ideal device design for such intervention is still evolving. AIM To assess the safety, efficacy, and short-term outcome of ventricular septal defect closure using LifeTechTM multifunctional (KONAR-MFTM) VSD Occluder. PATIENTS AND METHODS In a multicenre study, 44 patients with haemodynamically significant, restrictive ventricular septal defects underwent closure with the KONAR-MFTM device from April, 2019 to March, 2020. Clinical, echocardiographic, and angiographic data were collected and reviewed. Patients were followed up at 1, 3, 6, and 12 months. RESULTS The median age and weight were 8 (1.7-36) years and 20 (11-79) kg. Of 44 patients, 8 (18%) had a high muscular and 36 (82%) had a perimembranous defect, of which 6 had mild prolapse of the right coronary cusp. The median ventricular septal defect size was 8.8 (3.9-13.4) mm. A retrograde approach was adopted in 39 (88.6%) patients. Nine patients (20.5%) had a small residual leak and there was a slight increase in aortic regurgitation in one patient. One device, which embolised to pulmonary artery was retrieved, and the defect was closed with a larger device. At a median follow-up of 13 (5-18) months, the residual leak persisted in 1 (2.3%) patient. Mild aortic regurgitation in one patient remained unchanged. There were no major complications. CONCLUSION Percutaneous closure of ventricular septal defect using KONAR-MFTM device is safe and effective in short and midterm follow-up including selected patients with perimembranous defect and mild prolapse of the right coronary cusp.

Abstract
Transcatheter device intervention is now offered as first line therapy for many congenital heart defects (CHD) which were traditionally treated with cardiac surgery. While off-label use of devices is common and appropriate, a growing number of devices are now specifically designed and approved for use in CHD. Advanced imaging is now an integral part of interventional procedures including pre-procedure planning, intra-procedural guidance, and post-procedure monitoring. There is robust societal and industrial support for research and development of CHD-specific devices, and the regulatory framework at the national and international level is patient friendly. It is against this backdrop that we review transcatheter implantable devices for CHD, the role and integration of advanced imaging, and explore the current regulatory framework for device approval.

Abstract
Device occlusion of perimembranous ventricular septal defect is gaining popularity with the emergence of newer, softer occluders and improved technical know-how. We report a 26-year-old lady with a moderate size perimembranous ventricular septal defect who had a new onset of bundle branch block shortly after device closure. The patient subsequently developed a complete atrio-ventricular heart block.

Abstract
Background Transcatheter closure of aneurysmal perimembranous ventricular septal defect (pmVSD), pmVSD near the aortic valve, and intracristal VSD (icVSD) with symmetrical or asymmetrical ventricular septal defect occluders still presents significant challenges. We report our experience with transcatheter closure of pmVSD and icVSD using Amplatzer duct occluder II (ADO II) in children. Method We retrospectively analyzed all children, who presented to our hospital consecutively between March 2014 and June 2020 for attempted transcatheter closure of pmVSD or icVSD with the ADO II device. Standard safety and last-follow-up outcomes were assessed and compared. Results In total, 41 patients underwent transcatheter closure of VSD with the ADO II (28 in pmVSD and 13 in icVSD groups) with a median age of 3.5 years (total range: 0.9 to 12 years) and median weight of 15.0 kg (total range: 10.0 to 43.0 kg). Implantation was successful in 40/41 patients (97.5%, 27/28 in pmVSD group, 13/13 in icVSD group). One patient with mild aortic valve prolapse in pmVSD group developed new-onset moderate aortic regurgitation after a 4/4 mm ADO II was deployed; however, this resolved after the device was retrieved and successfully replaced with a 5 mm zero eccentric VSD occluder. There was no procedure-related mortality. After a median follow-up of six months (total range: 6 to 72 months), complete closure rates were 85.1% and 76.9% among pmVSD and icVSD groups, respectively. In the pmVSD group, one case of new-onset moderate tricuspid regurgitation was observed at six months, and there was one case of severe tricuspid regurgitation that had progressed from mild tricuspid regurgitation at 12 months. No serious complications were noted in the icVSD group. Conclusion ADO II provides a safe and reproducible alternative for the closure of perimembranous and intracristal ventricular septal defects with a diameter less than 5 mm in young children.

Abstract
OBJECTIVE The aim of this study was to evaluate the safety and efficacy of the Cardi-O-Fix plug used for the treatment of muscular ventricular septal defects. METHODS We retrospectively reviewed the medical records of five patients with muscular ventricular septal defects who underwent transcatheter closure using the Cardi-O-Fix Plug, from November 2017 to August 2019. The median age was 5.1 years (range: 3.2-6.5). Their median body weight was 18.1 kg (range: 13.4-21.8). All the patients underwent detailed two-dimensional Doppler and colour flow imaging by transthoracic echocardiography. The left ventricular median defect size of the muscular ventricular septal defects was 5.6 mm (range: 5.3-7.0). The right ventricular median defect size of the muscular ventricular septal defects was 3.9 mm (range: 3.3-4.7). All the procedures were performed on beating hearts. RESULTS All the patients underwent successful device implantation with no displacement or detachment, they have complete echocardiographic closure at the 1-year follow-up. There were no occluder-related arrhythmia, chordae tendineae rupture, tricuspid insufficiency, aortic regurgitation, haemolysis, or embolisation. CONCLUSIONS Application of the Cardi-O-Fix plug appears to be a feasible, safe, and effective treatment option for patients with muscular ventricular septal defects. Longer follow-up periods are warranted to prove the conclusion for long-term outcomes.

Abstract
We present a case of a persistent false lumen after ascending aorta replacement due to Stanford Type A dissection treated by endovascular means. The main entry tear was occluded with an atrial septal defect closure device, sealing the false lumen. A total of five additional stents were implanted to centralise and secure the flow in the true lumen. CT scan at 6-month follow-up showed excellent results with a decreased total aortic diameter and thrombosed false lumen.

Abstract
Transcatheter closure has been widely accepted as a highly effective way to treat abnormal blood flows and/or embolization of thrombus in the heart. It allows the closure of four types of congenital heart defects (CHDs) and stroke-associated left atrial appendage (LAA). The four types of CHDs include atrial septal defect (ASD), patent foramen ovale (PFO), patent ductus arteriosus (PDA), and ventricular septal defect (VSD). Advancements in the materials and configurations of occlusion devices have spurred the transition from open-heart surgery with high complexity and morbidity, or lifelong medication with a high risk of bleeding, to minimally invasive deployment. A variety of occlusion devices have been developed over the past few decades, particularly novel ones represented by biodegradable and 3D-printed occlusion devices, which are considered as next-generation alternatives to conventional Nitinol-based occlusion devices due to biodegradability, customization, and improved biocompatibility. The aim here is to comprehensively review the next-generation occlusion devices in terms of materials, configurations, manufacturing methods, deployment strategies, and (if available) experimental results or clinical data. The current challenges and the direction of future work are also proposed. STATEMENT OF SIGNIFICANCE: Implantation of occlusion devices has become a widely accepted and highly effective treatment for occluding abnormal blood/thrombus flow within the heart. Due to the serious complications such as erosion and displacement of conventional Nitinol-based occluders, next-generation occluders with reduced risk of complications and improved biocompatibility has emerged. Here, we comprehensively review the next-generation occluders developed for atrial septal defect (ASD), patent foramen ovale (PFO), patent ductus arteriosus (PDA), ventricular septal defect (VSD), and left atrial appendage (LAA), with special emphasis on biodegradable occluders. Besides, intelligent materials (e.g., automatically deployable shape memory polymers) and rapid customized manufacturing methods (3D/4D printing) for the fabrication of occluders are also introduced. Lastly, the directions of future work are highlighted.

[PMID: 34239725 PMCID: PMC8241517 DOI: 10.1155/2021/1625915] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/13/2021] [Revised: 06/09/2021] [Accepted: 06/12/2021] [Indexed: 11/17/2022] Open
Abstract
OBJECTIVES To observe and analyze the long-term change of different types of arrhythmias after transcatheter closure of perimembranous ventricular septal defect (pmVSD). METHODS We retrospectively collected the data of patients who underwent pmVSD closure in our institution from March 2002 to December 2010. RESULTS One hundred thirty-nine patients met the inclusion criteria, of which 265 (25.5%) had early arrhythmia. They were classified into two categories: conduction abnormality (191/1039; 18.4%) and origin abnormality (94/1039; 9.0%), including 20 patients with both types of arrhythmias. The median follow-up time was 84.5 months, and 103 patients (103/191; 53.9%) with early conduction block got permanent arrhythmias, while only three patients (3/94; 3.2%) with early anomalous origin arrhythmias still had an abnormal electrocardiogram. Serious arrhythmias (28/1039; 2.7%), including II° atrioventricular block (AVB), III° AVB, and complete left bundle branch block (CLBBB), can appear immediately in the early postoperative period (21 patients) or in the late outset (seven patients) after several months or even years (6 months to 8.3 years). Twenty patients (20/21; 95.2%) with serious arrhythmia in the early postoperative period improved after early treatment, but six patients relapsed or worsened during follow-up. At the endpoint, severe arrhythmia persisted in 13 patients, of which four patients got permanent pacemaker implanted, and one patient with recurrent CLBBB died from heart failure. CONCLUSIONS The probability of delayed CAVB or bundle branch block after VSD closure is low but often occurs several years after surgery. Therefore, long-term ECG follow-up should last for several years or even decades. Serious arrhythmias that appear early after transcatheter pmVSD closure may impose a risk of recurrence although they have been cured already. Close attention should be paid to the changes of cardiac function in patients with CLBBB after VSD closure, and the severity of such arrhythmia should be taken seriously and reexamined.
