Polymeric bioresorbable coronary scaffolds: the hype is over, but the dream lives on

“We tend to overestimate the effect of a technology in the short run and underestimate the effect in the long run.”

Roy Amara’s law

Bioresorbable coronary scaffolds (BRS) have been developed to achieve stenosis dilatation and stenting while uncaging the coronary vessels from permanent metallic structures. Uncaging the vessels in order to allow restoration of physiology has become a significant unmet need, especially when dealing with complex multivessel or diffuse disease that requires long vessel segments to be stented. The timing, however, for introducing the disruptive bioresorbable technology could not have been worse. First-generation BRS were ...
