Changes in SEC grade on TEE from the first to repeat
ablation
Changes in the SEC grade from the first session to the repeat session in
patients undergoing TEE are shown in Table 7 and Figure 5. Among
patients with a SEC grade 0 in the first session, 46% (225/493) did not
undergo TEE at the repeat sessions. This trend was stronger in the early
repeat group (≤180 days) than in the late repeat ablation group
(>180 days) (82% vs. 16%, p < 0.001). In
contrast, all 11 patients with SEC grade 4 at the first session were
examined by TEE at repeat sessions, but the SEC grade improved in some
patients.
