Bioresorbable Vascular Scaffolds (BVS) are polymer-based materials implanted in the
coronary arteries in order to treat atherosclerotic lesions, based on the concept that once the lesion
has been treated, the material of the implanted stent will undergo a process of gradual resorption
that will leave, in several years, the vessel wall smooth, free of any foreign material and with its
vasomotion restored. However, after the first enthusiastic reports on the efficacy of BVSs, the recently
published trials demonstrated disappointing results regarding long-term patency following
BVS implantation, which were mainly attributed to technical deficiencies during the stenting procedure.
Intracoronary imaging could play a crucial role for helping the operator to correctly implant
a BVS into the coronary artery, as well as providing relevant information in the follow-up period.
This review aims to summarize the role of intracoronary imaging in the follow-up of coronary
stents, with a particular emphasis on the role of intravascular ultrasound and optical coherence tomography
for procedural guidance during stent implantation and also for follow-up of bioabsorbable
