This document discusses tools and techniques for facilitating left atrial appendage closure (LAAO) procedures. It provides data on success rates from clinical studies and registries of various LAAO devices. It also outlines a global strategy for LAAO, including recommendations for the pre-procedure, procedure, and post-procedure phases. Examples of specific tools and techniques discussed are imaging planning with CT and TEE, use of ICE and microTEE during the procedure, sedation versus general anesthesia, and techniques for early hospital discharge post-procedure. Two case examples of LAAO procedures are also presented.

51. TEE probe S8-3t:
• Has a shaft width of 5.2 mm and length of 85
mm, a transducer tip width of 7.5 mm,
height of 5.5 mm, and length of 18.5 mm.
• The microTEE transducer is a 32-element
phased array transducer that is equipped with
2D B-mode echocardiography, colour Doppler,
pulse-wave and continuous- wave Doppler, M-
mode, and colour flow M-mode features.
• It has a centre frequency of 6 MHz on a
bandwidth of 3.2 to 7.4 MHz.
