It was common sense, that DCB therapy is currently not a valid option given the lack of evidence and actual guidelines. In fact, this critical view on DCB therapy is supported by recent European Society of Cardiology (ESC) guidelines on the management of chronic coronary syndromes (CCS) [1] . A few years ago, DCB therapy had been considered a recommended procedure for the treatment of in-stent restenosis [2], but this has been retracted in the latest CCS guidelines [1] . The reasons for this downgrade have been discussed controversially, especially the focus on efficiency (target lesion revascularization) while not observing hard clinical endpoints such as myocardial infarction and death being in favor of DCB treatment by avoiding additional stent layers [3] . There was also consensus in the ESC guidelines that DCB have no role in the treatment of de novo lesions [2] . But do these views on DCB therapy actually reflect the available clinical evidence [4–8]?  \nDCB therapy is one of the hot topics at international scientific meetings. The number of scientific publications on DCB therapy is increasing exponentially and so is the evidence for DCB therapy [7, 9] . One may therefore ask: Is the criticism and neglect of DCB therapy still justified?  \nImportantly, this treatment method is not new. The first experimental description of the procedure was published  \n* Bruno Scheller [bruno.scheller@uks.eu](bruno.scheller@uks.eu)  \n1 Clinical and Experimental Interventional Cardiology, University of Saarland, Homburg/Saar, Germany  \n2 Department of Internal Medicine III, Saarland University Hospital, Homburg/Saar, Germany  \n3 Department of Medicine IV, Clinic Hietzing, Vienna, Austria  \nmore than 20 years ago [10], followed by the first-in-man study in the New England Journal of Medicine [11] . The justification for DCB are the limitations of drug elutingstents (DES) . The rate of percutaneous coronary interventions (PCI) for in-stent restenosis is still up to 10% of all PCI [12] . Beyond the first year after DES implantation, a device-associated event rate of 2 to 3% can be expected without flattening of the curve over time [13, 14] . The risk increases with the number and length of the implanted DESand increases further as the vessel diameter decreases [14] . Patients with risk factors such as diabetes mellitus are particularly affected [14] . It therefore makes sense to consider alternatives to permanent implants, at least to reduce their total number and length [9] .  \nBaumer and colleagues deserve recognition and congratulations for their contribution to the growing clinical evidence of DCB therapy [15] . In the current issue of Clinical Research in Cardiology, they present a propensity score matched analysis of 606 patients with treatment of de novo lesions with either DES or DCB. The median follow-up time was 5.7 years without significant differences in cardiovascular or all-cause mortality, major adverse cardiovascular events (MACE), acute myocardial infarction, or any revascularization between DES and DCB. Importantly, the authors observed a trend toward lower rates of target lesion revascularization in patients with small vessel disease (SVD), and in bifurcation side branch lesions in favor of DCB treatment [15] .  \nTheir findings compare well to randomized clinical trials (RCT) in SVD. The largest RCT to date, the Basket Small 2 study showed non-i","cbCaiooKyJ4bQh4H","https://ap.wps.com/l/cbCaiooKyJ4bQh4H","pdf",1065897,"English","# DCB therapy: quo vadis?\n## Background and guideline position\n## Emerging evidence vs prior skepticism\n## Comparative findings: DCB versus DES\n## Evidence strengths, limitations, and practical implications","[{\"question\":\"Why is DCB therapy viewed skeptically in current guideline discussions?\",\"answer\":\"The text states that DCB therapy is considered not a valid option due to lack of evidence and actual guideline support, including downgrading from earlier recommendations for in-stent restenosis.
