The power of gold: a tip for an uncrossable ostial lesion

摘要

Uncrossable lesions are lesions that cannot be crossed with a?balloon or microcatheter after guide wire crossing. They constitute a?considerable challenge in coronary interventions and are associated with poor outcome in patients undergoing rotational atherectomy (RA) [1]. Most of the documented methods cannot be applied in true aorto-ostial lesions with severe stenosis. Such lesions require a?nonstandard approach that has not been precisely described in any expert documents so far [2–4].
