Invest-to-treat drug-coated balloon strategy in chronic total occlusion percutaneous intervention for high-risk stent failure patients

Key Points

• This study aims to evaluate the feasibility and safety of a drug-coated balloon (DCB) strategy in patients with chronic total occlusion (CTO) and high-risk stent failure (HR-SF).
• Conducted as a prospective study
• Included patients with chronic total occlusion and high-risk stent failure
• Evaluated outcomes of a DCB strategy
• Assessed the effectiveness of a redo-DCB approach as an alternative to extensive stenting
• DCB strategy shown to be feasible and safe for CTO patients with HR-SF
• Most patients achieved favorable early outcomes using a DCB-only approach
• Redo-DCB strategy presented as a promising alternative for suboptimal initial results
