Background: Dual stenting technique (DST) is still
mandatory for some true bifurcation lesions (BLs), but drug-coated balloon (DCB)
alone may offer a new optional treatment with the potential benefits of fewer
implants. However, procedural safety presents a concern when using DCB-only to
treat true BLs. This study sought to explore the safety and efficacy of the
DCB-only strategy for the treatment of true BLs. Methods: Sixty patients
with TBLs were randomly assigned to be treated by a DCB-based strategy or
DST-based strategy. All patients received angiographic follow-up scheduled after
one-year and staged clinical follow-up. The primary endpoint was the one-year
late lumen loss (LLL) and cumulative major cardiac adverse events (MACEs)
composed of cardiac death (CD), target vessel myocardial infarction (TVMI),
target lesion thrombosis (TVT), or target vessel/lesion revascularization
(TLR/TVR). The secondary endpoint was the one-year minimal lumen diameter (MLD),
diameter stenosis percentage (DSP) or binary restenosis (BRS), and each MACE
component. Results: The baseline clinical and lesioncharacteristics were
comparable with similar proportions (20.0% vs. 23.3%, p = 1.000) of
the complex BLs between the two groups. At the one-year follow-up, LLL was
significantly lower in the DCB-based group (main-vessel: 0.05
