CONCLUSION
LAA closure, usually performed for patients with atrial fibrillation
significant risk of thrombosis who cannot tolerated warfarin, can be
performed safely and simultaneously in selected patients with
significant ASD with chronic atrial fibrillation. Performing them
together simplifies the procedure and may be performed regardless of the
CHADS2,
CHA2DS2-VASc and
HAS-BLED scores. This study may pave the way for a possible novel
indication for left atrial appendage closure. However, larger scale
study is indicated before such an indication can be widely recommended.
