Here, the authors perform a large exome-wide study for venous thromboembolism and identify 18 potential risk genes, including 4 new genes, revealing a significant role of rare coding variants, and offering insights into genetic risk factors.

Left atrial appendage occlusion (LAAO) has been rapidly adopted for stroke prevention in patients with non-valvular atrial fibrillation and a contraindication to oral anticoagulation. Ongoing and planned clinical trials on LAAO and the development of new devices might expand clinical indications and address the remaining challenges of device-related thrombus and peridevice leak.

Data from the ARIES-HM3 trial show that excluding aspirin from the antithrombotic regimen in patients with advanced heart failure and a left ventricular assist device reduces the number of bleeding events and does not increase the risk of thromboembolism.

Current risk assessment and treatment strategies for venous thromboembolism (VTE) consider genetic factors only in a limited way. New work shows a more pervasive role of common variants in VTE risk, inspiring genetic predictors that surpass and complement individual clinical risk factors and monogenic thrombophilia testing.

In the phase II AXIOMATIC-TKR trial, the oral, selective factor XIa inhibitor milvexian provided dose-dependent protection against venous thromboembolism in patients undergoing knee arthroplasty.

Uncertainties remain about the diagnostic and therapeutic strategy to prevent left ventricular thrombus formation after myocardial infarction. In particular, the roles of predisposing factors and prophylactic anticoagulation have not been sufficiently considered. We propose an ‘uncertainties flowchart’ with the aim of stimulating research on the topic.
