Abstract:
Although reported failure rates of the Watchman device are low, the ballshaped device is not suitable for shallow and multilobed left atrial appendages (LAAs). The LAmbre device is available in two configurations - standard (cover 4-6 mm larger in diameter than the umbrella) and special (cover 12- 14 mm larger than the umbrella) - which allows the closure of a wide range of LAA anatomies. This case illustrates that the LAmbre device can be used for complex LAA anatomies that are not suitable for the Watchman device.
