Continuation versus Interruption of Oral Anticoagulation during transcatheter aortic-valve implantation (TAVI)
Primary resultResult — go to the resultRisk difference 1.7 percentage points 95% CI −3.1 to 6.6Authors' conclusion
In patients undergoing TAVI with a concomitant indication for oral anticoagulation, periprocedural continuation was not noninferior to interruption of oral anticoagulation during TAVI with respect to the incidence of a composite of death from cardiovascular causes, stroke, myocardial infarction, major vascular complications, or major bleeding at 30 days.
