Blood transfusion is associated with impaired outcome after transcatheter aortic valve implantation.

Objectives: We sought to evaluate the relationship of blood transfusion after transcatheter aortic valve implantation (TAVI) and mid-term outcome to improve patient selection and periprocedural treatment.

Background: Increasing evidence suggests a negative influence of blood transfusion on outcomes of patients with cardiovascular diseases. While the adverse impact of bleeding events on survival has been documented after TAVI, data on the impact of postoperative blood transfusions are scarce.
