Peri-device leakage. Left panel: transoesophageal echocardiogram with colour Doppler showing <3 mm peri-device leakage of Watchmann device at 3 months follow-up. Middle panel: transoesophageal echocardiogram with colour Doppler showing >7 mm peri-device leakage of Watchmann device at 2-year follow-up. Right panel: transoesophageal echocardiogram with colour Doppler showing persisting peri-device leakage after additional implantation of a second device (AVP 2) at 1-month follow-up.

PVI) (Figure 1). APTT: 50-70 s) (until INR > 2.0), aspirin (80 mg/day), and acenocoumarol (target INR: 2.0-3.0). At three months of follow-up, transoesophageal echocardiography (TEE) showed less than 3 mm peri-device leakage (Figure 1), which was considered as successful LAAO. We performed a TEE one week after this stroke and it showed a significant increase in peri-device leakage of more than 7 mm (Figure 1). At one month follow-up, persisting peri-device leakage (4 mm) was observed on TEE (Figure 1).
