Rotational atherectomy effectively treats complex coronary lesions unsuitable for conventional angioplasty. Using a lower burr-to-artery ratio, this study achieved successful outcomes with reduced complications, enhanced by angioplasty and stenting.

Area of Science:

  • Interventional Cardiology
  • Vascular Surgery

Background:

  • Rotational atherectomy (RA) was developed for complex coronary artery lesions.
  • Cases suboptimal for conventional percutaneous transluminal coronary angioplasty (PTCA) require alternative approaches.

Purpose of the Study:

  • To evaluate the efficacy and safety of rotational atherectomy.
  • To assess outcomes in patients with B2 and C type coronary lesions.

Main Methods:

  • Retrospective analysis of 60 RA procedures in 54 patients from April 2001 to March 2003.
  • Utilized a lower burr-to-artery ratio during procedures.
  • Combined RA with percutaneous transluminal coronary angioplasty (PTCA) and stenting.

Main Results:

  • Successful treatment of B2 and C type coronary lesions.

  • Lower burr-to-artery ratio correlated with decreased immediate procedural complications.
  • Adjunctive PTCA and stenting improved angiographic results.

    • Conclusions:

    • Rotational atherectomy is a viable option for complex coronary lesions.
    • Careful selection of burr size is crucial for safety.
    • A combined strategy of RA, PTCA, and stenting yields acceptable clinical results.
