ABSTRACT
BACKGROUND:
Percutaneous left atrial appendage closure (LAAC) has increased for those who need alternative to long-term anticoagulation with non-valvular atrial fibrillation (NVAF). METHODS ANDRESULTS:
From September 2019, after initiating WATCHMAN (Boston Scientific, Maple Grove, MN, USA) device implantation, we established Transcatheter Modification of Left Atrial Appendage by Obliteration with Device in Patients from the NVAF (TERMINATOR) registry. Utilizing 729 patients' data until January 2022, we analyzed percutaneous LAAC data regarding this real-world multicenter prospective registry. A total of 729 patients were enrolled. Average age was 74.9â¯years and 28.5â¯% were female. Paroxysmal AF was 37.9â¯% with average CHADS2 3.2, CHA2DS2-VASc 4.7, and HAS-BLED score of 3.4. WATCHMAN implantation was successful in 99.0â¯%. All-cause deaths were 3.2â¯%, and 1.2â¯% cardiovascular or unexplained deaths occurred during follow-up [median 222, interquartile range (IQR 93-464) days]. Stroke occurred in 2.2â¯%, and the composite endpoint which included cardiovascular or unexplained death, stroke, and systemic embolism were counted as 3.4â¯% [median 221, (IQR 93-464) days]. Major bleeding defined as BARC type 3 or 5 was seen in 3.7â¯%, and there was 8.6â¯% of all bleeding events in total [median 219, (IQR 93-464) days].CONCLUSIONS:
These preliminary data demonstrated percutaneous LAAC with WATCHMAN device might have a potential to reduce stroke and bleeding events for patients with NVAF. Further investigation is mandatory to confirm the long-term results of this strategy using this transcatheter local therapy instead of life-long systemic anticoagulation.Palavras-chave
