E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
The objective of this study is to assess the safety and efficacy of using bivalirudin instead of unfractionated heparin (UFH) in transcatheter aortic valve replacements (TAVR). The hypothesis is that bivalirudin will reduce bleeding rates compared to UFH, and will improve the overall clinical outcomes of TAVR patients. |
L’obiettivo di questo studio è di valutare la sicurezza e l’efficacia dell’uso di bivalirudina al posto di eparina non-frazionata (UFH) in interventi di sostituzione transcatetere della valvola aortica (TAVR). L’ipotesi è che la bivalirudina riduca i tassi di sanguinamento rispetto all’eparina non-frazionata e che migliori gli esiti clinici complessivi dei pazienti sottoposti a sostituzione transcatetere della valvola aortica. |
