Single-centre, Registry Trial, the Patients Presented With Stable Coronary Artery Disease
Single-centre, Registry Trial, the Patients Presented With Stable Coronary Artery Disease
This is a prospective study to analyze the outcome of provisional main vessel stenting on
 side branch by utilizing Two-Dimensional (2D) and Three-Dimensional (3D) frequency domain
 optical coherence tomography (FD-OCT). To analyze the fate of side-branch after provisional
 main vessel stenting based on morphology defined prior to PCI by OCT. Offline analysis of
 side branch impingement of the ostium of SB leading to acute loss in SB diameter area, carina
 shift and plaque shift will be also be performed.
Patients with stable coronary artery disease with angiographic main vessel lesion not
 involving side branch (SB) in whom provisional stenting strategy is planned will be
 recruited. All the participants of the registry will receive same stent. OCT will be
 performed to analyze plaque morphology, SB size, SB angle and side branch ostial involvement.
Inclusion Criteria:

 -  Over 18 years of age presenting with stable coronary artery disease.

 -  Angiographic lesion not involving side branch (SB) in whom provisional main vessel
 stenting strategy is planned after reviewing angiogram will be recruited

 Exclusion Criteria:

 -  Patient with lesion involving side branch ( >70 %) by angiogram and need pre-dilation.

 -  Patients with ostial left main artery lesions or ostial right coronary artery lesions

 -  Female patients with child bearing potential not taking adequate contraceptives or
 currently breastfeeding

 -  Known allergy to acetylsalicylic acid or clopidogrel.

 -  Planned surgery within 12 months.

 -  History of bleeding diathesis

 -  Major surgery within 15 days

 -  Life expectancy < 12 months.

 -  Patients with kidney dysfunction (CrCl<30)
