During the recent global iodine contrast media shortage in 2022, cardiac magnetic resonance imaging (CMR) was utilized for the first time for LAAC planning.

Among the 18 patients who underwent intraoperative TEE, there was no significant difference between CMR versus TEE in LAA thrombus exclusion (CMR 83%\u00a0vs. TEE 100% cases,\n                      <jats:italic>p<\/jats:italic>\n                      \u00a0=\u00a0.229), lobe count (CMR 1.7\u00a0\u00b1\u00a00.8\u00a0vs. TEE 1.4\u00a0\u00b1\u00a00.6,\n                      <jats:italic>p<\/jats:italic>\n                      \u00a0=\u00a0.177), morphology (\n                      <jats:italic>p<\/jats:italic>\n                      \u00a0=\u00a0.422), and accuracy of predicted device size (CMR 67%\u00a0vs. TEE 72% cases,\n                      <jats:italic>p<\/jats:italic>\n                      \u00a0=\u00a01.000).
