Background: Antithrombotic therapy after left atrial appendage closure (LAAC) in patients at high risk of bleeding remains controversial. We present real-world clinical outcomes of LAAC.Methods and Results: Data from 74 consecutive patients who received LAAC therapy between January 2020 and June 2022 were analyzed. Patients received 1 of 3 antithrombotic therapies according to the bleeding risk category or clinical event. Regimen 1 was based on a prior study, regimen 2 comprised a lower antiplatelet drug dose without dual antiplatelet therapy, and regimen 3 was antiplatelet drug administration for as long as possible to patients with uncontrollable bleeding who were required to stop anticoagulant drugs. Overall, 73 (98.6%) procedures were successful. Of them, 16 (21.9%) patients were selected for regimen 1, 46 (63.0%) for regimen 2, and 11 (15.1%) for regimen 3. Device-related thrombosis (13% vs. 0% vs. 0%, P=0.0257) only occurred with regimen 1. There was no difference in major bleeding event rates (6% vs. 2% vs. 9%, P=0.53).Conclusions: The post-LAAC antithrombotic regimen was modified without major concerns.

The structure of the perovskite photoabsorber is one of the utmost key aspects to influence the performance of perovskite solar cells. However, it is quite challenging to attain perovskite films meeting of the essential properties scuh as, large grain sizes with few grain boundaries, high crystallinity and homogeneous morphology, by the present preparation methods. In this mini review, we report on the recent progress of perovskite nanostructured solar cells fabricated by simple, low-cost techniques, and their physical properties. We discuss challenges and future research direction for the fabrication of nanostructured perovskite solar cells.
