A novel self-expanding basket (SEB) catheter effectively retrieved dislodged stents during percutaneous coronary intervention (PCI) in all patients. This promising device offers a safe and efficient solution for a challenging complication.

Area of Science:

  • Cardiovascular Interventions
  • Medical Device Technology
  • Interventional Cardiology

Background:

  • Stent dislodgement is a rare but difficult complication during percutaneous coronary intervention (PCI).
  • Current treatment options for dislodged stents are suboptimal.

Purpose of the Study:

  • To assess the feasibility of a novel self-expanding basket (SEB) catheter for retrieving dislodged stents.
  • To evaluate the efficacy and safety of the SEB catheter in a clinical setting.

Main Methods:

  • A novel SEB catheter with a self-expanding nitinol basket tip was developed.
  • Consecutive patients experiencing stent dislodgement during PCI were enrolled.
  • Procedure success was defined as complete stent retrieval without surgical intervention or vascular injury.

Main Results:

  • Six patients with dislodged stents were treated using the SEB catheter.
  • 100% procedural success was achieved in retrieving the dislodged stents.
  • No adverse safety events were observed during the procedures.

Conclusions:

  • The novel SEB catheter demonstrates favorable efficacy and safety for dislodged stent retrieval.
  • This preliminary study suggests the SEB catheter is a viable treatment option.
  • Further multicenter studies are needed to validate these findings.
