Conditions

Consecutive patients with ischemic heart disease who underwent elective transradial coronary intervention using FD-OCT/OFDI.

Interventions

FD-OCT/OFDI catheter is inserted through the sheath, and placed at the radial artery ostium. The sheath is extracted to a point of 1cm proximal to the puncture point. After continuous infusion of sali
