Comparison Between Main Branch and Side Branch Vessels
Comparison of Clinical, Electrical and Physiologic Significance Between Main Branch and Side Branch Vessels
The purpose of this trial is
- to compare the clinical significance of the main vessel and the side branch vessel using EKG, pain score and coronary wedge pressure
- to develop a new scoring system to predict the clinical significance of a side branch

Beskrivelse
Inclusion Criteria:
- Age ≥ 18
- Able to verbally confirm understandings of risks, benefits of receiving percutaneous coronary intervention (PCI) for true bifurcation lesions, and he/she or his/her legally authorized representative provides written informed consent prior to any study related procedure
- Significant stenosis at bifurcation lesion (>50% by visual estimate) which always includes stenosis of side branch (true bifurcation)
- Target main branch lesion(s) located in a native coronary artery with diameter of ≥ 2.5 mm and ≤ 4.5 mm. Target side branch lesion(s) in a native coronary artery with diameter of ≥ 2.25 mm
- Target lesion(s) amenable for PCI with final kissing balloon angioplasty for the side branch
Exclusion Criteria:
- Non-cardiac co-morbid conditions are present with life expectancy <1 year or that may result in protocol non-compliance (per site investigator's medical judgment)
- Patients refuse to give informed consent
- Patients with left main coronary artery stenosis
- Patients with total occlusion of the bifurcation lesion
- Patients with infarct-related artery at the lesion of interest
- Patients with left ventricular ejection fraction<40%
- Patients with primary cardiomyopathy
- Patients with chronic kidney disease defined as serum Cr>2.0
- Patients who have severe side effects or contraindication to adenosine
