Back to the future: the role of DCB for the treatment of coronary bifurcation

Coronary bifurcation lesion (CBL) is a common but challenging scenario in percutaneous coronary interventions. Drug-coated balloons (DCBs) are modern devices with attractive perspective in CBL treatment. In-stent restenosis, small vessel and diffuse de-novo coronary artery disease have been, so far, considered the ideal scenario for DCBs application. Studies assessing DCBs in de-novo CBL demonstrated the safety and efficacy of this strategy. However, the heterogeneity of the study populations and the presence of methodological limitations prevent from drawing definite recommendations. Considering that the best treatment of bifurcations has not yet been defined, the “leaving nothing behind” philosophy will be the topic of future studies.
