Short-term TEE follow-up
The first TEE follow-up rates were similar in both groups (87.9% vs 87.7%, P=0.968). The complete seal rates in the CM and MM groups were 68.6% and 65.0%, respectively. Peri-device leakage ≤3 mm was observed in the majority of patients during follow-up TEE examinations, except for two patients who had peri-device leakage of 4 mm in the MM group (Figure 4).
