Descriptive Information

• Brief Title: Basel Stent Kosten Effektivitäts Trial Drug Eluting Balloons vs. Drug Eluting Stents in Small Vessel Interventions
• Official Title: A Prospective, Randomized, Controlled, Open Label, Multicenter Trial to Test the Non-inferiority of Drug Eluting Balloon vs. Drug Eluting Stent Treatment in de Novo Stenoses of Small Native Vessels Regarding Efficacy and Safety
• Brief Summary: The investigators hypothesize that in a real-world population undergoing percutaneous coronary intervention (PCI) for de-novo stenoses in small native vessels with a diameter <3 mm, drug eluting balloons (DEB) are non inferior to third-generation drug eluting stents (DES).

Detailed Description

Drug-eluting balloons are an established treatment for in-stent stenoses and showed good results in small vessels. Moreover, the available data suggest that DEB are a promising new technique for the treatment of de-novo stenoses in small vessels if pre-dilatation is performed and geographical mismatch is avoided.

The aim of this study is to demonstrate that DEB is non-inferior to DES in a real-world population with respect to the combined clinical endpoint Major adverse cardiac events (MACE), defined as cardiac death, non-fatal myocardial infarction, and target vessel revascularization after 12 months.
