“…The mechanism of late‐onset CHB remains unknown. As it had been well described that late cardiac erosion or perforation can occur after atrial septal defect (ASD) closure with the metal devices , we presumed that the late‐onset CHB after the ASO deployment may be caused by continuing compression of the conduction tissue due to the shape memory property of nitinol. Although different in designs, all current available VSD occluders consist of a metal framework and synthetic fabrics.…”

“…However, some potential short comings remain unavoidable. In particular, some amount of cardiac erosion or perforation occurred during late followup and are potentially life threatening, which makes its long-term safety being questionable [4–6]. The mechanism of late-onset cardiac perforation remains unknown.…”

This study was conducted to evaluate the feasibility, safety, biocompatibility, and degradation features of a fully biodegradable occluder for closure of atrial septal defect (ASD) in an acute canine model. The ASD was created in 20 healthy mongrel dogs by the brockenbrough needle, and the fully biodegradable occluders were implanted by self-made delivery system. The success rate and complications were observed. Acute ASD models were successfully created in 18 dogs, and 16 occluders were successfully implanted in the ASD models. Animals were sacrificed at different times after procedure. The cardiac gross anatomy showed that all occluders were stable in the interatrial septum, no vegetation or thrombus formation was observed on the surface of all occluders. They were embedded into endogenous host tissue gradually at 12-week follow-up. Different periods of pathological observations suggested that the occluders degraded gradually over about 24 weeks and essentially became an integral part of the septum. Transcatheter closure of ASD in acute canine model using the fully biodegradable ASD occluder has the potential of a high successful rate of technique, excellent biocompatibility, and fewer complications with adequate, immediate, and short-term results.

Echocardiographic approach to catheter closure of atrial septal defects: patient selection, procedural guidance and post-procedural checks

Echocardiography is the imaging modality of choice to diagnose different types of atrial septal defect and to determine which defects are suitable for catheter occlusion. In addition to assessment of defect size and rims, transoesophageal echocardiography may be used to guide the procedure itself including device placement, procedural complications and post-procedural checks. This review covers a practical approach to this subject and is accompanied by online videos illustrating the technique.

The Influence of Morphological Changes in Amplatzer Device on the Atrial and Aortic Walls Following Transcatheter Closure of Atrial Septal Defects

Abstract: As the device becomes thinner, loses its flexibility, and often changes from a flare-to-closed shape on the aortic side over time, the edges of ASO can start to compress the atrial and aortic walls. However, erosion was not recognized in these cases.
