Design and Validation of a High-Fidelity Left Atrial Cardiac Simulator for the Study and Advancement of Left Atrial Appendage Occlusion.

Purpose: Atrial fibrillation (AF) is the most common chronic cardiac arrhythmia that increases the risk of stroke, primarily due to thrombus formation in the left atrial appendage (LAA). Left atrial appendage occlusion (LAAO) devices offer an alternative to oral anticoagulation for stroke prevention. However, the complex and variable anatomy of the LAA presents significant challenges to device design and deployment.

A paediatric patient presented with periorbital oedema and fever. Initially, there was low suspicion for cavernous sinus thrombosis and orbital cellulitis due to the presence of full extraocular movements. However, given worsening bilateral periorbital oedema, lethargy and sepsis, neuroimaging was performed demonstrating inflammation and enhancement of the leptomeninges and left cavernous sinus, and raising concern for cavernous sinus thrombosis in the setting of orbital cellulitis.

Introduction: We investigated the subsequent trends in age and antithrombotic therapy in patients who underwent transurethral resection of bladder tumor (TURBT) and examined the rate of perioperative complications.
Methods: Medical records of patients who underwent TURBT were retrospectively analyzed. We arbitrarily divided the observation years into three periods (I: 2007-2013, II: 2014-2018, and III: 2019-2023) to compare the trends in age and frequency of perioperative complications after TURBT between patients taking and those not taking antithrombotic drugs.
Direct factor Xa inhibitors versus low molecular weight heparins or vitamin K antagonists for prevention of venous thromboembolism in elective primary hip or knee replacement or hip fracture repair.

Background: People undergoing major orthopaedic surgery are at increased risk of postoperative thromboembolic events. Low molecular weight heparins (LMWHs) are recommended for thromboprophylaxis in this population. New oral anticoagulants, including direct factor Xa inhibitors, are recommended as alternatives.

Andexanet Alfa in Acute Intracranial Hemorrhage in Patients Receiving an Oral Factor Xa Inhibitor (ANNEXA-I), the first ever randomized controlled trial of a reversal agent for direct oral anticoagulants, was published in 2024. The trial, which randomized patients with intracranial hemorrhage to andexanet alfa or usual care, was mandated by the United States Food and Drug Administration as part of its conditional approval in 2018. This approval was originally based on the single-arm trial, The Andexanet Alfa, a Novel Antidote to the Anticoagulation Effects of Factor Xa Inhibitors (ANNEXA-4).
