ABSTRACT
Purpose of Review First-generation bioresorbable scaffolds (BRS), largely represented by the poly-l-lactic acid (PLLA) ABSORB (Abbott Vascular, Temecula, Illinois, US), have demonstrated, in low to moderate lesion complexity, similar efficacy to current generation metallic drug-eluting stents. However, a trend toward more device thrombosis has been observed, especially when the scaffolds are used in off-label situations. In this review, we address the most relevant drawbacks of these devices and, based on the available scientific data, we visit the scenarios where there is more uncertainty about their indication, trying to identify the lesions/patients to whom this technology should be voided at its current stage of development. Recent Findings Based on available data from randomized trials and observational real world registries, the use of first generation BRS has been associated with a trend to higher acute/subacute thrombosis rate, which might be partially explained by the peculiarities related to their deployment technique, such as the need for precise vessel sizing and caution on post-dilation. Special attention should be paid when using these devices to treat small coronary arteries
