Visualization of tissue prolapse between coronary stent struts by optical coherence tomography: comparison with intravascular ultrasound.

A 65-year-old man underwent cardiac catheterization for unstable angina pectoris. The coronary angiogram revealed a significant stenosis of the right coronary artery, which was treated with a 3.0×16 mm NIR stent. A postintervention coronary angiogram showed excellent results, and intravascular ultrasound (IVUS; 30 MHz, Ultracross, Boston Scientific) showed a well-deployed stent (Figure, A). A 3.2 F optical coherence tomography (OCT) catheter, advanced to the same site, showed well-apposed …
