Transradial Crossover Balloon Occlusion Technique for Primary Access Hemostasis During Transcatheter Aortic Valve Replacement: Initial Experience With the Oceanus 140 cm and 200 cm Balloon Catheters.

Objectives: The crossover balloon occlusion technique (CBOT) facilitates primary access hemostasis in patients undergoing transfemoral transcatheter aortic valve replacement (TAVR). The CBOT is usually performed through the contralateral femoral artery. The aim of this study was to evaluate, in patients undergoing TAVR, the safety and feasibility of transradial CBOT using the new Oceanus balloon dilatation catheter (iVascular).

Balancing the Risks of Thrombosis and Bleeding Following Transcatheter Aortic Valve Implantation: Current State-of-Evidence.

While transcatheter aortic valve implantation (TAVI) has rapidly evolved as an acceptable alternative to conventional surgical aortic valve replacement in elderly, high-risk surgical candidates with critical aortic stenosis, thrombotic and bleeding complications remain relatively frequent and potentially life-threatening. Thrombotic events during and following TAVI relate to the dynamic interplay between the systemic burden of atherosclerotic disease, atrial arrhythmias, device and native aortic valve interactions, as well as platelet and coagulation cascade activation. Bleeding in the acute setting relates primarily to access site vascular complications, but also appears related to pre-existing renal impairment and anemia.
