Drug-Coated Balloons in All-Comer Population-Are We There Yet?

With the advancement of interventional coronary procedures, drug-coated balloons have become an increasingly common alternative to drug-eluting stents in the treatment of various lesions. This paradigm shift stems from several advantages that DCBs entail, including a reduction in stent length burden, the possibility of late vessel positive remodeling, and the preservation of bifurcation anatomy. Conversely, several studies compared the efficacy of DCB treatment to stents or POBA in various scenarios. In this review, we will discuss the areas in which a DCB can be of paramount importance. We will begin by examining the role of DCBs in in-stent restenosis, for which the current practice guidelines do not clearly state the role of this technology, as opposed to the previous ones, in which it was mentioned as a first-line armamentarium. We will then discuss the indications and advantages of using DCBs in de novo lesions, concerning both small and large vessels, with growing emphasis on diffuse lesions. Lastly, we will address the current data on the use of DCBs in special scenarios such as the treatment of chronic total occlusion and left main and bifurcation lesions, without forgetting the primordial role of drug-eluting stents in all these lesions.
