Intraprocedural thrombus formation in the left atrial appendage (LAA) was observed in 3 (1.46%) patients in the ICE group and 15 (11.63%) patients in the TEE group (\n                      <jats:italic>P<\/jats:italic>\n                      \u2009&amp;lt;\u20090.05) before LAAC. Total fluoroscopy time and dose in the ICE group were less than those in the TEE group. The total \u201cone-stop\u201d turnaround time and LAAC procedure time in the ICE group were significantly shorter than those in the TEE group (\n                      <jats:italic>P\u2009<\/jats:italic>\n                      &amp;lt;\u20090.05). Postoperative esophagus discomfort, nausea and vomiting, and hypotension were more often seen in the TEE group (\n                      <jats:italic>P<\/jats:italic>\n                      \u2009&amp;lt;\u20090.001).
