Key result
Optimal implantation of bioresorbable scaffolds requires meticulous lesion selection, adequate pre-dilatation, and appropriate post-dilatation, which can be facilitated by intravascular imaging.
Optimal implantation techniques, including meticulous lesion preparation, accurate sizing, and intravascular imaging guidance, are essential to overcome the mechanical limitations of bioresorbable scaffolds and reduce adverse events.
Supports meticulous lesion preparation and imaging for bioresorbable scaffolds; leaves open outcome benefits in prospective trials.
INTRODUCTION: With new developments in percutaneous coronary intervention (PCI), such as the introduction of bioresorbable scaffolds (BRS), percutaneous treatment of coronary artery diseases has entered a new era. Without metallic remnants, BRSs appear able to overcome several limitations of the existing metallic stents and provide a physiologic treatment of coronary artery pathology. AREAS COVERED: BRS have different mechanical properties compared to the traditional metallic stents that should be taken into account during their implantation. Lesion selection, device sizing and satisfied pre-dilatation should be implemented prudently. Although intravascular imaging is not mandatory for the implantation of BRSs it may have a value in optimizing device deployment assess final results and reduce the risk of device related adverse events such as re-stenosis, or scaffold thrombosis. This review aims to reveal the crucial points about the methods of optimization in each steps of BRS implantation. Expert commentary: The target lesions for BRS should be selected meticulously. Pre-dilatation, post-dilatation and intra-vascular imaging techniques should be implemented appropriately to avoid undesirable events after scaffold implantation.

Tenekecioğlu et al. (2016) conducted a review in Coronary artery disease. Bioresorbable scaffolds (BRS) vs. Metallic stents was evaluated. Optimal implantation of bioresorbable scaffolds requires meticulous lesion selection, adequate pre-dilatation, and appropriate post-dilatation, which can be facilitated by intravascular imaging.
