Unlabelled: Accurate estimation of the Lung Shunt Fraction (LSF) is a standard of care in yttrium-90 ( Y) radioembolization treatment planning to prevent excessive lung irradiation due to arterio-venous shunting in the liver. LSF is assessed using Tc macroaggregated albumin ( Tc-MAA) imaging, but this approach adds risk, complexity, and expense to the treatment planning. This study investigates the potential of Contrast-Enhanced Computed Tomography (CECT) as a non-invasive alternative for LSF estimation.

Introduction: Rates of morbidity and mortality are high in the setting of Fontan physiology and effective medical therapies are not well-established. Clinical trials assessing phosophodiesterase-5-inhibitors, such as sildenafil, have not demonstrated major benefit in patients with a Fontan-type circulation but have only included stable, well-functioning people.
Methods: We sought to retrospectively characterize the people followed by the ANZ Fontan Registry prescribed sildenafil >30 days post Fontan-surgery.

Left atrial veno-arterial extracorporeal membrane oxygenation (LAVA-ECMO) in cardiogenic shock (CS) is a novel mechanical cardiocirculatory support strategy that provides robust cardiocirculatory support and simultaneous left and right atrial venting by way of a multifenestrated transeptal catheter. We performed a single-center retrospective analysis of all patients aged ≥18 years with CS who underwent LAVA-ECMO at a quaternary care institution from 2018 to 2023. Clinical outcomes and prehemodynamics and posthemodynamics were evaluated.

Purpose: To report a case of an asymptomatic patient with a pulmonary aneurysmal arterio-venous malformation successfully treated with a vascular plug.
Case Report: An active 30-year-old male patient, residing at 3000 ft above sea level was referred due to an incidental finding on a CT scan of a 37 mm vascular mass localized in the lower lobe of the right lung, which corresponded to a pulmonary arteriovenous malformation with a single feeding artery. The patient was treated with an Amplatzer vascular plug, which effectively excluded the afferent vessel.

We report our experience of managing a massive haemothorax caused by a ruptured, previously unknown, pulmonary arteriovenous malformation (pAVM) at 34 + 5 weeks of gestation, which proved to be a manifestation of hereditary haemorrhagic telangiectasia (HHT), also known as Osler-Weber-Rendu syndrome. The patient underwent an emergency caesarean section under general anaesthesia after placement of a chest tube and gave birth to a healthy infant. A postoperative thoracic computed tomography angiography highlighted the presence of the large pAVM.
