“First-in-man” use of bioresorbable vascular scaffold in saphenous vein graft

A 52-year-old male underwent coronary angiography for non-ST-elevation myocardial infarction. He had a known history of diabetes mellitus and also triple vessel disease with prior coronary artery bypass grafting (CABG) six years ago. Angiography showed total occlusion of the left anterior descending (LAD), circumflex and right coronary arteries (RCA). Left internal mammary graft to LAD was patent. However, there were two critical stenoses in the mid-body of the SVG-RCA and SVG-obtuse marginal (OM) grafts (Figure 1A and Figure 1B). We proceeded to perform percutaneous coronary intervention of both lesions with the prophylactic use of an embolic protection device. After predilation of both lesions, an Absorb™ bioresorbable vascular scaffold 3.0×18 mm (Abbott Vascular, Santa Clara, CA, USA) was implanted in the mid-body of the saphenous vein graft (SVG)-RCA (Figure 1C) whereas a XIENCE PRIME™ 3.0×23 mm stent (Abbott Vascular) was implanted in the mid-body of the SVG-OM (Figure 1D). The final angiographic results were good and there was no in-lab complication. He presented three months later with atypical chest pain and underwent cardiac computed tomographic angiography (CCTA). Both bioresorbable vascular scaffold (BVS) and XIENCE PRIME stent were widely patent on CCTA (Figure 1E and Figure 1F). No blooming artefact was observed within the treated SVG-RCA segment with the BVS platinum markers clearly seen on CCTA.
