Comparative StudyAnatomic and procedural predictors of paravalvular aortic regurgitation after implantation of the Medtronic CoreValve bioprosthesis.
The purpose of this study was to determine the predictors of aortic regurgitation (AR) after transcatheter aortic valve implantation (TAVI). ⋯ The occurrence of significant AR after TAVI can be predicted by anatomic and procedural variables. A model such as that presented can be used to select suitable patients for this procedure and guide operators during implantation of the device.

Randomized Controlled Trial Comparative StudyAspirin plus clopidogrel therapy increases early venous graft patency after coronary artery bypass surgery a single-center, randomized, controlled trial.
We sought to evaluate the effect of aspirin plus clopidogrel versus aspirin alone on saphenous vein graft occlusion at 3 months after coronary artery bypass grafting (CABG). ⋯ Aspirin plus clopidogrel is more effective in venous graft patency than aspirin alone in the short term after CABG, but further, long-term study is needed. (The Clopidogrel and Aspirin After Surgery for Coronary Artery Disease; NCT00776477).
