Original Title: EWOLUTION: 3-months outcome of Left Atrial Appendage Closure with the WATCHMAN device in Europe.
Presenter: Martin Bergmann.
This study presented the experience of left atrial appendage closure with the WATCHMAN device outside the selected population of prior randomized clinical trials. The study included more than 1000 patients in this single arm multicenter registry; 39% of these patients had high bleeding risk or had a history of bleeding.
Implantation success was 98.5% in cases with high adverse events rate or 3.2% death rate. Regarding major bleeding, stroke or procedure/device related event, there were no significant differences in drug regime in the first 3 months after implantation.
Conclusion
The left atrial appendage closure device WATCHMAN showed a high success rate and low periprocedural complications rate despite the high bleeding risk of the population involved. Bleeding was the most common event in the first three months and there were no differences in DAPT or new anticoagulants in this period.
