Multicenter Study Comparative Study
A comparison of patient characteristics and 30-day mortality outcomes after transcatheter aortic valve implantation and surgical aortic valve replacement for the treatment of aortic stenosis: a two-centre study.
It is unclear whether transcatheter aortic valve implantation (TAVI) addresses an unmet clinical need for those currently rejected for surgical aortic valve replacement (SAVR) and whether there is a subgroup of high-risk patients benefiting more from TAVI compared to SAVR. In this two-centre, prospective cohort study, we compared baseline characteristics and 30-day mortality between TAVI and SAVR in consecutive patients undergoing invasive treatment for aortic stenosis. ⋯ Both measured and unmeasured confounding limit the conclusions that can be drawn from observational comparisons of TAVI versus SAVR. Our study indicates that TAVI could be associated with either substantial benefits or harms. Randomised comparisons of TAVI versus SAVR are warranted.

Meta Analysis
Bifurcation stenting with drug-eluting stents: a systematic review and meta-analysis of randomised trials.
We sought to determine if outcomes differ between provisional (elective side branch stenting) compared to a routine two-stent strategy (mandatory side branch stenting) for the treatment of bifurcation stenoses of the coronary arteries using drug-eluting stents. ⋯ While death, stent thrombosis, and restenosis were similar between the treatment groups, MI was more common with the two-stent strategy. Thus, compared to a routine two-stent strategy, provisional stenting yields similar efficacy with superior safety and lower costs.

Transcatheter aortic valve replacement (TAVR) is a promising therapeutic option for patients with severe aortic stenosis (AS) considered at too high risk for conventional aortic valve replacement. The balloon-expandable Edwards valve can be implanted using either the transfemoral or transapical routes, depending on arterial ilio-femoral suitability. The aim of the study was to evaluate the usefulness of ilio-femoral angiography as an initial screening tool for TAVR using the transfemoral approach with the Edwards SAPIEN valve. ⋯ In the course of haemodynamic and angiographic evaluation of patients with severe symptomatic aortic stenosis, angiography of the ilio-femoral access can be used as a first screening modality to determine potential candidacy for a transfemoral TAVR using a balloon expandable THV.
