Figure 1. Angiographic and optical coherence tomography (OCT) images of the lesion. A) A subocclusive stenosis of the posterolateral branch just under the implanted tricuspid annuloplasty ring. A1) OCT image at the beginning of the stenosis, just before the posterior descending artery (PD). A2) OCT image of the most stenotic part with visible artery narrowing caused by entrapment, without intimal injury. The area encircled by the white line represents tissue beyond the adventitia layer. B) Angiographic and OCT results after stent implantation demonstrating appropriate stent expansion before and after the PD (B1, B2). In OCT image B2, a lesser extent ...
