The Efficacy and Medium to Long-Term Follow-Up of Transcatheter Retrograde Closure of Perimembranous Ventricular Septal Defects via the Femoral Artery With Amplatzer Duct Occluder II in Children.

ABSTRACT: Objective: The aim of this study was to assess the efficacy and safety of transcatheter retrograde closure of perimembranous ventricular septal defect (pmVSD) via the femoral artery with an Amplatzer Duct Occluder II (ADO II) in children. Methods: The clinical and follow-up data of 102 children who had successfully undergone transcatheter retrograde closure of pmVSD via the femoral artery with Amplatzer Duct Occluder II (ADO II) from February 2012 to June 2019 in our center were retrospectively reviewed. Results: In 102 of 103 patients, the defects were successfully closed (99.0%). The average age was 4.03 ± 1.84 years and the mean weight was 17.50 ± 5.58 kg. The mean diameter of the defects was 2.58 ± 0.63 mm. Hundred of the occluders had a waist length of 4 mm. The complete closure rate was 89.2% 24 h after the procedure and 98% at the last follow-up. The follow-up period ranged from 6 to 92 months, with a median of 36 months. One child developed new mild aortic regurgitation (AR), and 9 patients developed new mild tricuspid regurgitation (TR). During follow-up, TR disappeared in 5 patients and decreased in 4 patients, and AR relieved in one patient. One patient developed intermittent complete left bundle branch block 4 days after the procedure and recovered sinus rhythm 2 days later. No serious complications occurred. Conclusion: Transcatheter retrograde closure of pmVSD via the femoral artery with ADO II in children is safe, feasible, and effective in selected patients.

Short- and medium-term follow-up of transcatheter closure of perimembranous ventricular septal defects.

Project description:BACKGROUND:Transcatheter closure of perimembranous ventricular septal defects is one of the greatest challenges in interventional cardiology. Short- and midium-term follow-up data for large samples are limited. This report presents our experience with transcatheter closure of perimembranous ventricular septal defects using an occluder. METHODS:Two hundred fifty-three patients included in the database of the Second Affiliated Hospital and Yuying Children's Hospital from January 2011- December 2015 with transcatheter closure of perimembranous ventricular septal defects and discharged from follow-up. All patients were invited for clinical and transthoracic echocardiography, electrocardiogram, and thoracic radiography check-up. RESULTS:Device implantation was successful in 252 of 253 patients (99.6%). The median age was 42?months (range 27-216?months). The median follow-up duration was 36?months (range 6-60?months). The mean defect diameter was 3.5?±?1.4?mm and the mean size of the ventricular septal defect rim below the aortic valve was 3.7?±?1.8?mm. The mean diameter of the devices used was 4?mm. Thirty-seven patients developed arrhythmia after the procedure and recovered within 24?months; four patients had hemolysis and four had moderate tricuspid valve regurgitation. No other serious adverse event occurred during the follow-up period. CONCLUSION:Transcatheter closure of perimembranous ventricular septal defects using an occluder is safe and effective in most patients.

Echocardiographic Classification of Perimembranous Ventricular Septal Defect Guides Selection of the Occluder Design for Their Transcatheter Device Closure.

Project description:BackgroundPerimembranous ventricular septal defects (VSDs) has proximate relation to the aortic and tricuspid valves as well as the conduction tissues. Transcatheter closure utilizes various off-label device designs.MethodsPerimembranous VSD without aortic margin were classified as group A, with thick aortic margin as group B, with membranous septal aneurysm as group C and defects restricted by tricuspid valve attachments as group D. The proposed ideal design was asymmetric device in group A; duct occluder I (ADOI) and muscular ventricular septal occluder (MVSO) in group B; thin profile duct occluder II (ADOII) in group C and ADOI in group D. Device was 0-2 mm larger than the defect.ResultsEighty patients with VSD measuring 6.83 ± 2.87mm underwent successful closure. Device was retrieved before release in one group A and one group C patient due to aortic regurgitation. Asymmetric device was used in 16 group A defects. Among group B defects, ADOI was used in 5, ADOII in 5, MVSO in one and asymmetric device in 3. Group C defects were closed with ADOI in 7, ADOII in 10 and asymmetric device in 3. Three patients with multiple exits had 2 ADOII devices. Group D defects were closed using ADOI in 20 and ADOII in 10 patients. There was no late aortic regurgitation or heart block on a follow-up exceeding 7 years.ConclusionsThis echocardiographic classification helps device selection in every single patient. While asymmetric device is uniquely suited for group A defects, different designs are appropriate in the other groups.

Transcatheter device closure of perimembranous ventricular septal defects: mid-term outcomes.

Project description:The aim of this study was to evaluate the safety and efficacy of transcatheter closure for perimembranous ventricular septal defect (pmVSD) and its long-term results. The most common congenital heart condition is pmVSD. Transcatheter closure of pmVSD is a recently described technique with limited results for mid- to long-term follow-up.Between June 2002 and June 2008, 848 patients with pmVSD were enrolled in our study and treated percutaneously with pmVSD occluders. All patients were followed up until December 2008, an average of 37 months. According to colour Doppler transthoracic echocardiography before the intervention and ventriculography, the average end-diastolic pmVSD size was 5.1 and 5.4 mm, respectively. Placement of the device was successful in 832 patients (98.1%) and the median device size was 8.6 mm. During follow-up, 103 adverse events (12.4%) were reported. Most adverse events were categorized as minor and there were nine major adverse events (8.7%), including two complete atrioventricular block requiring pacemaker implantation. Kaplan-Meier estimates showed >85% freedom from major or minor adverse events during a maximal follow-up of 79 months.In experienced hands, transcatheter pmVSD closure can be performed safely and successfully with low morbidity and mortality. Long-term prognostic results are favourable, and the transcatheter approach provides a less-invasive alternative that may become the first choice in selected pmVSD patients. This trial is registered with ClinicalTrials.gov, number NCT00890799.

Successful percutaneous treatment of recurrent post-infarction ventricular septal rupture using an Amplatzer duct occluder.

Project description:A 78-year-old woman was brought to our hospital for chest pain with shock status. An electrocardiogram showed ST elevation in the precordial leads. Echocardiography showed an anteroseptal wall motion abnormality with left-to-right shunt at the apex. Emergency coronary angiography revealed occlusion in the mid portion of the left anterior descending artery, and left ventriculography showed ventricular septal rupture (VSR). Despite successful emergency surgical VSR repair, the VSR recurred 10 days after surgery, and the patient required intra-aortic balloon pumping and mechanical ventilation. Although reoperation for VSR closure was attempted 33 days after admission, open heart surgery was not completed due to severe tissue adhesions from the prior cardiac surgery. The patient ultimately underwent transcatheter closure for VSR using an Amplatzer duct occluder 56 days after hospital admission, and her hemodynamics markedly improved. She was transferred to a regional hospital for rehabilitation without oxygen therapy or intravenous treatments 81 days after the percutaneous intervention. In conclusion, percutaneous device closure of post-infarction VSR may be an alternative treatment to surgical repair for inoperable cases. <Learning objective: Ventricular septal rupture (VSR) is a rare but frequently fatal complication of acute myocardial infarction and often requires early surgery. However, the recurrence rate of VSR after surgery is high, and reoperation is often difficult because of the critical nature of the patients' condition. The present case report highlights the effectiveness of percutaneous closure of VSR using Amplatzer devices for seriously ill patients with a high risk of reoperation.>.

Transcatheter Closure of Iatrogenic Right Ventricular Perforation With Amplatzer Duct Occlude II.

Project description:Iatrogenic cardiac perforation is a major complication of cardiac intervention. Surgical correction of perforation is standard of care. We discuss a pacing wire induced right ventricular perforation during the coronavirus disease-2019 (COVID-19) pandemic. Open heart surgery was high risk due to age and COVID-related significant lung involvement. As a bailout measure, the perforation was successfully closed with transcatheter intervention. (Level of Difficulty: Advanced.).

A case report: Amplatzer occluder device closure of an iatrogenic ventricular septal defect following radiofrequency ablation.

Project description:BackgroundInterventricular septal perforation is an extremely rare complication of radiofrequency ablation (RFA), with an incidence of 1%. The most common mechanism is a 'steam pop', which can be described as 'mini-explosions' of gas bubbles. Data for percutaneous repair of cardiac perforations due to RFA are limited.Case summaryA 78-year-old female patient was referred to our department for the treatment of two iatrogenic ventricular septal defects (VSDs) following radiofrequency ablation (RFA) of premature ventricular contractions. One week post-ablation, chest pain and progressive dyspnoea occurred. Transthoracic echocardiography detected a VSD, diameter 10 mm. Hence, iatrogenic, RFA-related myocardial injury was considered the most likely cause of VSD, and the patient was referred to our tertiary care centre for surgical repair. Cardiovascular magnetic resonance (CMR) imaging demonstrated border-zone oedema of the VSD only and confirmed the absence of necrotic tissue boundaries, and the patient was deemed suitable for percutaneous device closure. Laevocardiography identified an additional, smaller muscular defect that cannot be explained by analysing the Carto-Map. Both defects could be successfully closed percutaneously using two Amplatzer VSD occluder devices.DiscussionIn conclusion, this case demonstrates a successful percutaneous closure of a VSD resulting from RFA using an Amplatzer septal occluder device. CMR might improve tissue characterization of the VSD borders and support the decision if to opt for interventional or surgical closure.

Patent foramen ovale and closure technique with the amplatzer occluder.

Project description:Proof that percutaneous closure of the patent foramen ovale (PFO) is superior to medical treatment is still incomplete. Paradoxical embolism is a rare event occurring over decades rather than years. None of the 4 randomized trials published carried enough patients or was followed up for long enough to reach superiority endpoints. All data, however, point to a benefit of PFO closure. Free wall erosion (exceedingly rare) and triggering of atrial fibrillation (in about 1% of patients) are the only noteworthy complications. They are outweighed by the supposedly prevented events of paradoxical embolisms, such as stroke, transient ischemic attacks, myocardial infarctions, or other systemic embolisms. Medical treatment with perhaps the exception of lifelong oral anticoagulation provides less protection. During a 10-year follow-up of a comparative study the annual mortality was significantly lower in the patients with PFO closure (0.4%) than in those with medical treatment (1.1%, P < 0.03). PFO closure can be accomplished in less than 1 hour with immediate resumption of physical activity. It represents thus a kind of mechanical vaccination.

Predictors and long-term outcomes of heart block after transcatheter device closure of perimembranous ventricular septal defect.

Project description:BackgroundHeart block is the most common and concerning complication associated with transcatheter device closure of perimembranous ventricular septal defect (pmVSD) and its occurrence remains a great challenge for device closure.MethodsBetween June 2002 and June 2020, 1076 pediatric patients with pmVSD, who successfully underwent transcatheter device closure in our center, were enrolled in this cohort study, with a median follow-up of 64 months (range: 1 to 19 years).ResultsOf 1076 patients, 234 (21.8%) developed postprocedural heart block, with right bundle branch block being the most common (74.8%), followed by left bundle branch block (16.2%), and atrioventricular block (5.6%). Complete atrioventricular block occurred in 5 cases, including 3 cases with permanent pacemaker implantation, 1 case with recovery to normal sinus rhythm, and 1 case with sudden cardiac death. Most patients (97.9%) developed heart block within 1 week of procedure. Finally, 138 cases returned to normal cardiac conduction. Multivariate logistic regression revealed that thin-waist occluders (odds ratio [OR]: 1.759; 95% confidence interval [CI]: 1.023 to 3.022; P = 0.041), and oversized devices (OR: 1.809; 95% CI: 1.322 to 2.476; P < 0.001) were independently associated with occurrence of postprocedural heart block. Moreover, heart block was less likely to occur when the left disk of occluder was placed within the aneurysmal tissue (OR: 0.568; 95% CI: 0.348 to 0.928; P = 0.024).ConclusionThe outcome of postprocedural heart block is favorable in most cases. Oversized devices and thin-waist occluders should be avoided. Placement of the left disk of the device should into the aneurysmal tissue is highly recommended.
