Patients having \u22651 ECV were further analyzed. TEE was performed during implantation and at 6 weeks. In a subgroup of 77 patients, we compared MDCT with TEE at 6 weeks.<\/jats:p><jats:p>Overall, 135 patients (69 \u00b1 9 years; 70% male; CHA<jats:sub>2<\/jats:sub>DS<jats:sub>2<\/jats:sub>\u2010VASc score: 3.6 \u00b1 1.4; HAS\u2010BLED score: 2.5 \u00b1 0.6) received a LAA occluder (Watchman, n\u00a0=\u00a073; ACP\u20101, n\u00a0=\u00a059; Amulet, n\u00a0=\u00a03; PVI + LAA occluder, n\u00a0=\u00a091; and LAA occluder only, n\u00a0=\u00a044). Device implantation was successful in 131 (97%). Eight patients (5.9%) had major periprocedural complications (ischemic stroke\/transient ischemic attacks, n\u00a0=\u00a04, tamponade, n\u00a0=\u00a02, device thrombosis, n\u00a0=\u00a02, Dressler syndrome, n\u00a0=\u00a01). The periprocedural complication rate was similar between concomitant procedure and LAA occluder only (8\/91 vs. 5\/44; P\u00a0=\u00a00.6). Twelve patients (9%) died (procedure\u2010related, n\u00a0=\u00a02; 1%) during follow\u2010up of 44 months (IQR: 43). MDCT (n\u00a0=\u00a077) at 6 weeks showed similar peridevice flow compared to TEE (TEE: 1.5 \u00b1 1.9 mm vs. MDCT: 1.1 \u00b1 2.2 mm, P\u00a0=\u00a00.25). Thromboembolic events occurred in 3 patients (CVA, n\u00a0=\u00a01; TIA, n\u00a0=\u00a02) during follow\u2010up. In total, 41 ECV were performed in 26 patients (1.6 \u00b1 0.9\/patient), 13 months (IQR: 24) after implantation (&lt;1 month: n\u00a0=\u00a08).
