Noninvasive coronary computed tomography analysis after bioresorbable scaffold implantation

Noninvasive coronary computed tomography angiography has shown to be an accurate method for the exclusion of significant coronary artery stenosis, with negative predictive values of 97%-99% [1,2]. However, in patients previously treated with percutaneous coronary interventions, the artifact from the metallic stent precludes appropriate luminal assessment [3]. In contrast, the bioresorbable vascular scaffold (ABSORB, Abbott Vascular, Santa Clara, CA) has a translucent polymeric backbone that allows for noninvasive coronary computed tomography angiography (CTA) [4].
