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

摘要

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.
