About this trial
The current role of the rotational atherectomy is for non-dilatable coronary lesions and for severely calcified lesions that may interfere with optimal stent expansion.
Severely calcified coronary lesions are associated with worse outcomes. In this regard, chronic kidney disease is associated with severely calcified coronary arteries.
Some evidence suggests that elective rotational atherectomy used by experienced operators can be safe and effective, minimizing time and complications for patients with heavily calcified lesions.
However, there is no direct randomized comparison between rotational atherectomy and angioplasty alone in the setting of chronic renal failure and with intravascular ultrasound assessment for detecting severely calcified coronary arteries.

Trial outcomes
Primary outcomes
The healthcare cost analysis between elective atherectomy and conventional atherectomy (bailout)

During follow-up 5 years.
Contrast-induced nephropathy
Contrast-induced nephropathy 48 hours after the procedure.
Stent placement success
Defined as expansion with \<20% residual stenosis assessed by intravascular ultrasound and TIMI 3 flow without crossover or stent failure
The amount of angioplasty balloons used in each group before stent deployment.
Number of semi-compliant and non-compliant balloons used during procedure deployment.
