The ICE WATCHMAN Trial

Overview

About this study

The aim of this multi-center study will be to assess the feasibility and safety of left atrial appendage (LAA) occlusion with the WATCHMAN™ device using a standardized intra-procedural intracardiac echocardiography (ICE) protocol under moderate sedation for procedural guidance. By eliminating the need for general anesthesia, we hope to show a reduction in procedural time, decrease use of supplemental invasive procedures (central venous line, invasive arterial pressure monitoring and transesophageal echocardiography) and quicker patient recovery time. This approach can decrease healthcare resource utilization and safely simplify left atrial appendage closure with the WATCHMAN device.
