Optimal visualization of five different stent layers during and after percutaneous coronary intervention for recurrent in-stent restenosis using optical coherence tomography (OCT).
Optical coherence tomography (OCT) has gained increasing popularity in the recent years. In this case, we documented optimal visualization of four stent layers that were seen during percutaneous coronary intervention for recurrent in-stent restenosis. OCT was clearly able to penetrate all of the neointimal tissue layers extending through to the last stent, which was near the adventitia. Our case demonstrates the excellent utility of OCT for detail assessment of a lesion with multiple stents. To our knowledge, this case is the first case report that could demonstrate excellent visualization of 5 different stent layers using OCT, extending through the deepest stent layer near the adventitia.
