Mechanical Vacuum Aspiration and Debulking of Large Vegetations During Cardiac Implantable Electronic Device Extraction
Authors' conclusion
In this contemporary study of PMD of large lead-associated vegetations, manual vacuum aspiration was feasible and appeared associated with better outcomes, including postoperative markers of infection severity, hospital stay, and, perhaps, mortality.
Study context
- Population
- Patients undergoing cardiac implantable electronic device (CIED) extraction with lead-associated vegetations, 2023–2025
- Participants
- 42 patients
- Exposure
- Percutaneous mechanical debulking vs no percutaneous mechanical debulking (PMD) during CIED extraction
- PMDn = 13
- Controlsn = 29reference
- Outcome
- Change in WBC count postprocedure vs baseline
Methodological details3 centres

Main finding
As reported in the abstract
Change in WBC count postprocedure vs baseline PMD mean 8.35% · Controls mean 21.1%
>20% increase
- PMD vs Controls: P = 0.046 — WBC decreased with PMD, increased in controls
Observational data: associations, not effects.
Further findings
Postextraction hospital stay
P = 0.056
One-month mortality
P = 0.401
Safety
- Extraction in both cohorts without major complications
