Would SYNTAX have been a positive trial if XIENCE V had been used instead of TAXUS? a meta-analysis of a first-generation vs. a second-generation drug-eluting stent system

Treatment options for coronary revascularization include percutaneous coronary intervention (PCI) and coronary artery bypass grafting (CABG). In the 'synergy between PCI with TAXUS and cardiac surgery (SYNTAX)' trial, PCI and CABG using state-of-the-art techniques (using paclitaxel-eluting stents and arterial grafts, respectively) were compared in the treatment of complex coronary artery disease. In Syntax, PCI was inferior to CABG at one year, entirely due to an increased repeat intervention rate. We hypothesised that the use of a superior drug-eluting stent system could reduce the need for repeat intervention.
