Randomized Controlled Trial Multicenter Study Comparative Study
Continuation versus Interruption of Oral Anticoagulation during TAVI.
One third of patients undergoing transcatheter aortic-valve implantation (TAVI) have an indication for oral anticoagulation owing to concomitant diseases. Interruption of oral anticoagulation during TAVI may decrease the risk of bleeding, whereas continuation may decrease the risk of thromboembolism. ⋯ 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.

ReviewAnticoagulation in patients with a history of heparin-induced thrombocytopenia who require cardiovascular surgery: is it okay to use heparin?
Heparin‑induced thrombocytopenia (HIT) is an adverse drug reaction with significant thromboembolic risk. Though there are models for use of nonheparin anticoagulants, heparin remains the preferred anticoagulant in many operative settings, especially cardiovascular surgery and percutaneous cardiac intervention. ⋯ If procedures cannot be delayed, approaches include intraoperative bivalirudin or intraoperative heparin with pre- or intraoperative plasma exchange or a potent antiplatelet agent, sometimes in combination with intravenous immunoglobulin. In subacute HIT B (immunoassay positive, functional assay negative) and remote HIT (immunoassay negative, functional assay negative), brief exposure to heparin in the intraoperative setting with close monitoring postoperatively is suggested due to the low risk of recurrent HIT.

Severe hemophilia A is managed with factor VIII replacement or hemostatic products that stop or prevent bleeding. Data on gene therapy with hematopoietic stem-cell (HSC)-based expression of factor VIII for the treatment of severe hemophilia A are lacking. ⋯ Gene therapy for hemophilia A with the use of lentiviral vector-transduced autologous HSCs resulted in stable factor VIII expression, with factor VIII activity correlating to vector copy number in the peripheral blood.
