Direct stenting without predilation is a safe and effective coronary intervention. This technique reduces procedure time, radiation exposure, and costs for selected patients undergoing coronary stenting.

Area of Science:

  • Interventional Cardiology
  • Cardiovascular Medicine
  • Medical Technology

Background:

  • Coronary stenting is a primary treatment for coronary lesions.
  • Improved antithrombotic regimens and high-pressure stent expansion have reduced risks.
  • Direct stent implantation (DSI) without predilation is a novel technique.

Purpose of the Study:

  • To evaluate the safety and efficacy of direct stenting without predilation.
  • To assess the impact of DSI on procedure time, radiation exposure, and cost.
  • To compare DSI with conventional stenting involving predilation.

Main Methods:

  • Retrospective review of 585 stent implantations (Feb-Jun 1998).
  • Identified 185 patients as candidates for DSI based on lesion characteristics.

  • DSI attempted in 123 patients; compared outcomes with 69 patients undergoing conventional stenting.

    • Main Results:

    • Successful direct stenting in 118 patients (96%) with no acute or subacute complications.
    • Significantly lower procedure time (45 vs. 64 min), radiation exposure (12 vs. 16 min), and cost (1,305 vs. 2,210 Euro) for DSI.
    • No significant difference in contrast dye usage was mentioned.

    Conclusions:

    • Direct stenting without predilation is safe and effective for selected coronary lesions.
    • DSI offers a viable method for cost containment in cardiovascular interventions.
    • This technique effectively reduces radiation exposure time during coronary procedures.
