Rotational Atherectomy through Inner Guiding Catheter System for 1.25 mm Rotational Burr Non-Crossable Heavily Calcified Coronary Stenosis

ABSTRACT

Among the various kinds of percutaneous coronary intervention techniques for balloon non-crossable severe calcified coronary stenosis, rotational atherectomy (RA) is known to be a therapy of choice. We describe a case in which a 1.25 mm RA burr non-crossable heavily calcified stenosis was successfully treated by the RA through '6 in 8 child-mother' guiding technique.
