Efficacy and safety of the VASCADE® MVP venous vascular closure device in patients undergoing percutaneous left atrial appendage occlusion with WATCHMAN.

Background: The VASCADE MVP venous vascular closure system is commonly used for percutaneous venotomy closure in catheter-based procedures utilizing sheath sizes 6-12 French. However, its application with larger sheaths such as ones required in left atrial appendage occlusion (LAAO) has yet to be explored.

Aims: This study compared the efficacy and safety of VASCADE MVP versus conventional Figure-of-8 sutures (Fo8) for femoral venotomy closure in patients undergoing Watchman LAAO.
