Oncologic emergencies have a high rate of morbidity and mortality. This review covers several scenarios of gastrointestinal malignancies presenting emergently as various acute abdominal pathologies. Radiologists should be familiar with the typical imaging findings, clinical presentations, and laboratory values which may suggest a background neoplasm, particularly when encountered in the context of an acute inflammatory state.

- The study compares the accuracy of the current STS online risk calculator for predicting mortality in patients undergoing TAVR against the older 2008 STS risk model.
- After analyzing data from over 1200 TAVR patients, it was found that the newer calculator predicted a significantly lower risk of mortality (6.3%) compared to the older model (7.3%).
- Notably, certain patients with conditions like chronic heart failure were more likely to be reclassified into a lower risk category with the new calculator, which may affect how previous TAVR studies are interpreted.
Objectives: We investigated the hemodynamic durability of the transcatheter aortic valves (TAVs) using the updated Valve Academic Research Consortium-2 (VARC-2) criteria.
Background: The updated VARC-2 consensus criteria combine flow-dependent and flow-independent echocardiographic parameters for hemodynamic assessment of TAVR. Data on the hemodynamic durability of TAV and clinical risk factors associated with valve hemodynamic deterioration (VHD) are lacking.
Objective: The aim was to compare outcomes in a subgroup of patients with infrapopliteal (IP) disease randomised to infrapopliteal vein bypass (VB) or plain balloon angioplasty (PBA) in the original BASIL trial.
Methods: A comparison of outcomes from patients randomised to VB or PBA undergoing revascularisation for severe limb ischaemia (SLI) because of IP disease with or without femoropopliteal disease. Data were extracted from case report forms from the BASIL trial.
