Clinical Report: Unstable Late Migration of a VSD Closure Device
Overview
This case study presents an unusual instance of late migration of a ventricular septal defect (VSD) closure device, occurring 18 months post-implantation. The device exhibited complete circumferential endothelialization, indicating long-term tissue incorporation prior to its migration.
Background
Ventricular septal defects (VSDs) are the most common congenital heart defects, with transcatheter closure becoming a preferred treatment due to its minimally invasive nature. While device embolization typically occurs shortly after implantation, this case highlights the rare possibility of late migration, emphasizing the need for ongoing surveillance post-procedure.
Data Highlights
No numerical data or trial data presented in the article.
Key Findings
Late device migration after VSD closure is exceedingly rare, with this case occurring 18 months post-procedure.
Serial imaging showed stable device positioning prior to migration, suggesting no early malposition or technical error.
Transcatheter closure of perimembranous VSDs using the Konar-MFO device has shown high procedural success rates and low complication profiles.
Device embolization is typically associated with early post-procedural periods, with an estimated incidence of approximately 0.4%.
Clinical Implications
This case underscores the importance of long-term follow-up and imaging after transcatheter VSD closure to monitor for potential late complications. Clinicians should be aware of the rare possibility of late device migration despite initial successful implantation.
Conclusion
The occurrence of late device migration in this case highlights the need for vigilance in post-procedural monitoring of VSD closure devices. Continued research and reporting on such rare events are essential for improving patient outcomes.
Researchers compare personalized versus standard prehabilitation and examine functional, immune, and postoperative outcomes before major elective surgery.
