ICE was associated with a statistically significant high procedure success rate compared to TEE (RR: 1.0055 with 95% CI [1.0006, 1.0104],\n                      <jats:italic>p<\/jats:italic>\n                      \u2009=\u20090.01), but there was no difference in procedure duration (MD: 3.07 with 95% CI [\u22124.67, 10.80],\n                      <jats:italic>p<\/jats:italic>\n                      \u2009=\u20090.44) between the two groups. However, compared to the ICE group, patients undergoing LAAO under TEE guidance required more than one device more often (RR: 1.39 with 95% CI [1.23, 1.57],\n                      <jats:italic>p<\/jats:italic>\n                      \u2009&lt;\u20090.01).

It can also reduce the need for GA and adverse effects and resources associated with it, require fewer devices, and demonstrate comparable safety and efficacy outcomes, though it may increase the risk of pericardial effusion.
