Measure
Rotational Atherectomy
Rotational atherectomy (RA) for the treatment of bifurcation lesions to remove plaque with minimal injury to adjacent normal arterial segments and potentially reduce plaque shifting, the "snow plow" effect.
CBA/PTCA
Cutting Balloon Angioplasty (CBA) or Percutaneous transluminal coronary angioplasty (PTCA) Cutting Balloon Angioplasty: Cutting balloon is a special balloon catheter with three or four microsurgical blades attached longitudinally to its surface, suitable for creating discrete longitudinal incisions in the atherosclerotic target coronary segment during balloon inflation. Lesion preparation will be performed using Cutting Balloon or conventional balloon
