  • Orbital Atherectomy for the Treatment of Long (≥25–40 mm) Severely Calcified Coronary Lesions: ORBIT II Sub-Analysis

    Highlights

    • Coronary intervention of long calcified lesions is complex, high risk and may require more intensive lesion preparation.
    • Orbital atherectomy treatment of longer lesions was associated with a higher in-hospital non-Q-wave MI rate.
    • Rates of MI were similar in the short and long groups when using the SCAI definition of clinically relevant MI after PCI.
    • 3-year MACE rates were similar in the short (<25 mm) and long (≥25-40 mm) lesion groups.

    Abstract

    Background

    Orbital atherectomy (OA) is an effective method of lesion preparation of severely calcified vessels prior to stent deployment. Long calcified lesions may lead to higher risk of post-procedural complications, yet the optimal treatment strategy has not been established. In this study we sought to determine the safety and efficacy of OA in patients with long (≥25–40 mm) calcified target lesions.
