| Adaptive to shear stress |
Greater risks of acute strut fracture |
| Addresses physician’s and patient’s desires to avoid a permanent implant |
Higher early rates of scaffold thrombosis and target vessel-related myocardial infarction |
| Allows treatment of in-stent restenosis without permanent additional metal layer |
Intraluminal scaffold dismantling |
| Avoids full metal jacket |
Lack of visibility on angiography |
| Facilitation of the return of vessel vasomotion-Facilitation of noninvasive imaging follow-up without artifacts |
Reduced deformability |
| Future interventions in vessels with previous stenting |
Reduced ductibility |
| Future surgery in vessels with previous stenting |
Some devices require cold storage and specific deployment techniques |
| Late expansive remodeling |
Special attention to procedural techniques |
| Late luminal enlargement |
Thicker/wider struts with larger crossing profile (more difficult to deliver) |
| Reduction in the amount of dual antiplatelet therapy |
|
| Restoring late bypass surgery options |
|
| Unjailing of covered side branches |
