Venous thromboembolism (VTE) recurrence carries significant mortality and morbidity. Accurate risk assessment and effective treatment for patients with acute pulmonary embolism (PE) is important for VTE recurrence prevention. We examined the association of VTE recurrence with risk stratification and PE treatment. ⋯ The recurrence was negatively associated with longer (≥6 months) anticoagulation (HR 0.473, 95% CI 0.285-0.787, P=0.004), especially in patients with higher risk (HR 0.394, 95% CI 0.211-0.736, P=0.003) and unprovoked PE (HR 0.248, 95% CI 0.122-0.504, P<0.001). ESC high-risk and intermediate-risk PE, unprovoked PE and varicose veins increase recurrence risk. Longer anticoagulation treatment reduces recurrence, especially in higher risk and unprovoked PE patients.

An increasing number of individuals are on novel oral anticoagulants (NOAC) for anticoagulation instead of vitamin K antagonists (VKA) and roughly 10% of these individuals will require interruption of these agents for procedures annually. Recent evidence surrounding bridging as well as the FDA approval of a new NOAC call for a comprehensive review and update regarding periprocedural NOAC management. The periprocedural management of NOACs involves striking a balance between the risks of bleeding and thromboembolism associated with interruption, bridging, and reinitiation of anticoagulation. ⋯ For patients at high risk for thromboembolism, individual patient and surgical factors need to be considered before the decision to bridge is made. The benefit of bridging these patients who have a considerable risk of bleeding may not outweigh the benefits. Focused randomized studies on periprocedural management of NOACs are urgently needed.

Patients with a Fontan circulation tend to develop liver fibrosis, liver cirrhosis and even hepatocellular carcinoma. The aim of this study is to use the magnetic resonance technique diffusing-weighted imaging (DWI) for detecting liver fibrosis/cirrhosis in Fontan patients and to establish whether DWI results are associated with functional aspects of the Fontan circulation. ⋯ The results of the current study suggest that progressive liver damage due to chronic congestion and potential hypoperfusion is reflected in the liver ADC values in Fontan patients. This study highlights that liver damage in the context of the Fontan circulation might be far more common than previously thought, and that the implementation of liver assessment in the routine follow-up of Fontan patients is recommendable.
