Guiding catheter extension facilities high speed rotational atherectomy for distal right coronary artery lesion

摘要

Extensive coronary calcification may affect procedural outcomes of coronary angioplasty, resulting in impaired device deliverability, especially in distal locations of the stenosis [1]. In some cases, balloon predilatation is not enough for successful dilatation of the lesion and high speed rotational atherectomy is needed to perform the procedure. Due to the limited length of effective rotablation (advancer moving length – 7 cm), deliverability to the distal plaque location is impossible.
