Objectives

Narrative objectives1

We hypothesized that short single session (no more than 15 seconds) can reduce the incidence of slow flow following rotational atherectomy to severely calcified coronary lesions as compared to long single session (20-30 seconds).
The purpose of this study is to compare the incidence of slow flow following rotational atherectomy to severely calcified coronary artery lesions between short single session versus long single session.

Assessment

Primary outcomes

Slow flow just following rotational atherectomy.

Slow flow is defined as [(initial TIMI-frame count)x1.1 minus (TIMI frame count just after rotational atherectomy) ] less than 0.

Absence of slow flow is defined as [(initial TIMI-frame count)x1.1 minus (TIMI frame count just after rotational atherectomy) ] not lower than 0.

If >/=2 burrs are used for rotational atherectomy, slow flow will be evaluated only after the initial burr cross the lesion. Once initial burr crosses the lesion, slow flow will not be evaluated for this study after the second burr cross the lesion.

If initial burr cannot cross the lesion and the second burr (typically smaller burr) cross the lesion, slow flow will be evaluated for this study after the second burr cross the lesion.

If halfway rotational atherectomy is performed, slow flow will be evaluated just after halfway rotational atherectomy.

Key secondary outcomes

Periprocedural myocardial infarction. Complications such as vessel perforation.

Key inclusion criteria

1. Patients with ischemic heart disease who undergo percutaneous coronary intervention using rotational atherectomy.

2. Patients who gave written informed consent.

3. Angiographically severe calcification in target lesions.

4. Intravascular imaging shows over 180 degree superficial calcification/calcified nodule, intravascular imaging devices cannot cross the lesion due to severe stenosis, or intravascular imaging device (typically optical coherent tomography) cannot provide valid images due to severe stenosis.

Key exclusion criteria

1. Less than 20 years-old.
2. Contraindication in instructions-for-use of Rotablator.
