Brief Summary:

The purpose of this study is to predict any changes in the side branch after stenting the main branch blood vessel using three dimensional intravascular images. (Frequency domain optical coherence tomography FD OCT).

Optical coherence tomography (OCT) is an established medical imaging technique that uses light to capture high-resolution, three-dimensional images of blood vessels. These images will be used before and after implanting the stent in the main blood vessel. Fractional Flow Reserve (FFR) test, which makes it possible for the interventional cardiologist to calculate blood flow across an area of a coronary artery, will be done after stenting and will help to determine if there are any changes in the side branch blood flow.

Arm Intervention/treatment
Active Comparator: Rotational atherectomy
Rotational atherectomy (RA)
Device: Rotational atherectomy
Rotational atherectomy 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.
Other Name: RA

Active Comparator: CBA/PTCA
Cutting Balloon Angioplasty (CBA) or Percutaneous transluminal coronary angioplasty (PTCA)
Device: 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
Other Name: CBA

Primary Outcome Measures :
  1. Number of Participants With Side Branch Compromise [ Time Frame: Day 1 ]
    Number of participants with Side Branch (SB) compromise which is defined as SB DS > 70%, or dissection or TIMI < 3

Secondary Outcome Measures :
  1. Number of Participants With SB Dissection [ Time Frame: Day 1 ]
    Number of participants with SB dissection

  2. Number of Participants With TIMI < 3 [ Time Frame: Day 1 ]
    Number of participants with TIMI flow grade < 3

  3. Number of Participants With SB DS >70% [ Time Frame: Day 1 ]
    Number of participants with Side Branch Diameter Stenosis (DS) > 70%

  4. Number of Participants With FFR Device Success [ Time Frame: Day 1 ]
    Number of Participants with successfully deliver Fractional Flow Reserve (FFR) wire to desired SB distal segment

  5. Number of Patients With FFR Wire Workhorse Capability [ Time Frame: Day 1 ]
    FFR Wire Workhorse Capability - Number of patients in which FFR wire was able to serve as rail to deliver additional interventional devices to target SB lesion
