Clinical Scorecard: Case Study: Unstable Late Migration of a Ventricular Septal Defect Closure Device with Endothelialization
At a Glance
Category
Detail
Condition
Key Mechanisms
Transcatheter closure using the Konar-MFO device, with late migration due to endothelialization and detachment, highlighting the rarity of such events.
Target Population
Care Setting
Key Highlights
Late device migration occurred 18 months post-implantation, a rare event.
Complete circumferential endothelialization confirmed prior to device detachment.
Initial device positioning was stable with no early complications.
Transcatheter closure associated with high procedural success and low complication rates.
Device embolization incidence estimated at approximately 0.4%.
Significance of late migration emphasized due to its rarity.
Guideline-Based Recommendations
Diagnosis
Use transthoracic echocardiography and angiography for VSD assessment, including specific imaging techniques from the case.
Management
Consider transcatheter closure for selected patients with perimembranous VSD.
Monitoring & Follow-up
Regular echocardiographic follow-up to assess device position and function, with emphasis on monitoring for late migration.
Risks
Potential for device embolization, residual shunt, and arrhythmias.
Patient & Prescribing Data
Konar-MFO device demonstrated effective closure with low complication rates, supported by case-specific data.
Clinical Best Practices
Ensure optimal device sizing based on imaging to minimize complications.
Monitor for late device migration through regular follow-ups, emphasizing the importance of ongoing assessment.
