Comparison of drug-eluting balloon versus drug-eluting stent in patients with in-stent restenosis: insight from randomized controlled trials.

Backgrounds: In-stent restenosis (ISR) remains an important issue even in the current drug-eluting stent (DES) era. We performed a meta-analysis to assess the clinical efficacy and safety of drug-eluting balloon (DEB) as compared with DES for the treatment of ISR.

Methods: The published literature was scanned by formal searches of electronic databases from January 2005 to February 2014.

Drug-coated balloon angioplasty for drug-eluting stent restenosis: insight from randomized controlled trials.

Background: The best treatment option for drug-eluting stent (DES) restenosis has not been established. We performed a meta-analysis to assess the clinical efficacy of drug-coated balloon (DCB) for the treatment of DES restenosis.

Methods: Trials were identified through a literature search from January 2005 through April 2014.
