Multicenter Study Meta Analysis
Bivalirudin versus heparin in patients treated with percutaneous coronary intervention: a meta-analysis of randomised trials.
Current recommendations on the use of bivalirudin in patients treated with percutaneous coronary intervention (PCI) are mostly based on trials comparing bivalirudin versus heparin plus planned glycoprotein IIb/IIIa inhibitor (GPI). Whether bivalirudin is also superior to heparin alone is still not well established. This meta-analysis investigates the efficacy and safety of bivalirudin versus heparin in patients treated with PCI without planned use of GPI. ⋯ Patients undergoing PCI randomised to therapy with either bivalirudin or heparin display a similar mortality. Bivalirudin as compared to heparin appears to reduce the risk of major bleeding at the expense of a higher risk of acute ST.

Transcatheter aortic valve implantation (TAVI) is an alternative therapeutic option for patients with severe aortic valve stenosis (AS) and elevated surgical risk. Previous studies have suggested that the occurrence of systemic inflammatory response syndrome (SIRS) in patients undergoing TAVI is associated with an unfavourable outcome. We sought to assess the impact of different interventional access routes (transapical [TA] vs. transfemoral [TF]) and valve types (Medtronic CoreValve® [CV] vs. Edwards SAPIEN XT® [ES]) on the incidence of SIRS. In addition, the prognostic value of SIRS was evaluated. ⋯ The occurrence of SIRS in the first 48 hours post procedure is associated with impaired prognosis following TAVI, but is independent from the chosen valve type and access route.
