Rotational atherectomy is an established tool to treat blocked arteries in the heart, in which the blockage is due to significant amounts of calcified material. In rotational atherectomy, a rotating instrument is used to break up the calcification before a stent is placed and helps restore blood flow to the heart. However, severely calcified regions are difficult to treat and even after treatment arteries can re-clog and major cardiac events occur. This study will test if rotational artherectomy with the addition of a cutting balloon

  • a balloon with microsurgical blades on its outer surface which make longitudinal incisions in the calcified area in order to open resistant clogs - will result in increased blood vessel lumen, more optimal stent expansion and decreased cardiac problems compared to current standard treatment.


This is a prospective, pilot study randomizing patients with stable Coronary Artery Disease undergoing Percutaneous Coronary Intervention for a de novo calcified lesion with drug eluting stent implantation to angioplasty with rotational atherectomy followed by cutting balloon (ROTA + CBA) or rotational artherectomy followed by plain old balloon (ROTA + POBA) in a 1:1 ratio.

The clinical investigation will be conducted at 2 centers in the US. 30 randomized subjects per site will be enrolled in this study. Subjects participating in this clinical investigation will be followed for 9 months. The expected duration of enrollment is approximately 6 months. The total duration of the clinical investigation is expected to be approximately 2 years.
