ABSTRACT

OBJECTIVES - The aim of this single center all-comers retrospective registry study was to assess the efficacy and safety of percutaneous coronary intervention (PCI) using drug-coated balloon (DCB) in de novo lesions including large proximal coronary arteries.

 

METHODS - A total of 487 PCIs were performed using paclitaxel-coated DCB in 562 de novo lesions with the possibility for bailout stenting in a patient population presenting with stable coronary artery disease (CAD) or acute coronary syndrome (ACS). Half of the patients had at least one risk factor for bleeding. All of the treated lesions were de novo and 60% of DCBs used were ≥ 3.0 mm in diameter. The median follow-up time was 18 months for MACE and 60 months for survival.

 

RESULTS - The total mortality after DBC only strategy was 2.3 and 9.3% at 12 months in stable CAD and ACS, respectively. The 12-month MACE rate was 7.1 and 12% in stable CAD and ACS. The rate of ischemia-driven target lesion revascularization was only 1.4% in stable CAD and 2.8% after ACS at 12 months. Median duration of DAPT was one month. The 12 month rate of significant bleeding (Bleeding Academic Research Consortium types 2-5) was 5.9%. Acute vessel closure occurred only in one case (0.2%) after DCB treatment. Bailout stenting was used in 12% of lesions.

 

CONCLUSIONS - PCI using DCB-only strategy with the possibility for provisional stenting is a safe and efficient in de novo coronary artery lesions in both stable CAD and ACS. This strategy may be useful especially in patients with high bleeding risk.
