Abstract
After percutaneous implantation of a cardiac occluder, a complex healing process leads to the device coverage within several months. An incomplete device coverage increases the risk of device related complications such as thrombosis or endocarditis. We aimed to assess the device coverage process of atrial septal defect (ASD) occluders in a chronic sheep model using micro-computed tomography (micro-CT). After percutaneous creation of an ASD, 8 ewes were implanted with a 16-mm Nit-Occlud ASD-R occluder (PFM medical, Cologne, Germany) and were followed for 1 month (N = 3) and 3 months (N = 5). After heart explant, the device coverage was assessed using micro-CT (resolution of 41.7 μm) and was compared to histological analysis. The micro-CT image reconstruction was performed in 2D and 3D allowing measurement of the coverage thickness and surface for each device. Macroscopic assessment of devices showed that the coverage was complete for the left-side disk in all cases. Yet incomplete coverage of the right-side disk was observed in 5 of the 8 cases. 2D and 3D micro-CT analysis allowed an accurate evaluation of device coverage of each disk and was overall well correlated to histology sections. Surface calculation from micro-CT images of the 8 cases showed that the median surface of coverage was 93±8% for the left-side disk and 55±31% for the right-side disk. The assessment of tissue reactions, including endothelialisation, after implantation of an ASD occluder can rely on in vitro micro-CT analysis. The translation to clinical practice is challenging but the potential for individual follow-up is shown, to avoid thrombotic or infective complications.

Percutaneous Closure of Atrial Septal Defects with the MemoPart Atrial Septal Occluder: The Early-Term Results of a Multicenter Study. Pediatr Cardiol 2022; 43:39-44. [PMID: 34401943 DOI: 10.1007/s00246-021-02688-w] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/14/2021] [Accepted: 07/23/2021] [Indexed: 11/28/2022]
Abstract
Atrial septal defect (ASD) is a common congenital heart disease with left-to-right shunt that may lead to pulmonary hypertension over time. Secundum ASD closure with transcatheter technique is currently the preferred method. The aim of this study was to evaluate the clinical experience and early-term outcomes of patients treated with a MemoPart ASD occluder device between June 2013 and June 2019. Fifty-six patients (35 females) with a mean age of 9.4 ± 6.6 years (range: 2-44 years) were included in the study. The diameters of the devices used to close the ASDs were 7-28 mm. The ratio of the device/defect diameter was 1.14:1. Atrial septal defect closure was applied successfully in all patients. The MemoPart septal occluder is a safe and effective device for ASD closure. In wide ASDs and cases with more than one deficient rim, weak rims, or wide and complicated cases, it can be used carefully with sufficient experience.

Abstract
Background—
Data are needed on the safety and efficacy of device closure of large atrial septal defects.
Methods and Results—
Between 1998 and 2013, 336 patients (161 children <15 years) with large, isolated, secundum atrial septal defects (balloon-stretched diameter ≥34 mm in adults or echocardiographic diameter >15 mm/m
2
in children) were managed using the Amplatzer device, at the Marie Lannelongue Hospital. Transthoracic echocardiographic guidance was used starting in 2005 (n=219; 65.2%). Balloon-stretched diameter was >40 mm in 36 adults; mean values were 37.6±3.3 mm in other adults and 26.3±6.3 mm/m
2
in children. Amplatzer closure was successful in 311 (92.6%; 95% confidence interval, 89%–95%) patients. Superior and posterior rim deficiencies were more common in failed than in successful procedures (superior, 24.0% versus 4.8%;
P
=0.002; and posterior, 32.0% versus 4.2%;
P
<0.001). Device migration occurred in 4 adults (2 cases each of surgical and transcatheter retrieval); in the 21 remaining failures, the device was unreleased and withdrawn. After a median follow-up of 10.0 years (2.5–17 years), all patients were alive with no history of late complications.
Conclusions—
Closure of large atrial septal defects using the Amplatzer device is safe and effective in both adults and children. Superior and posterior rim deficiencies are associated with procedural failure. Closure can be performed under transthoracic echocardiographic guidance in experienced centers. Early device migration is rare and can be safely managed by device extraction. Long-term follow-up showed no deaths or major late complications in our population of 311 patients.
