Oral Anticoagulant Use in Patients With Atrial Fibrillation and Chronic Kidney Disease: A Review of the Evidence With Recommendations for Australian Clinical Practice.

Chronic kidney disease is common in patients with atrial fibrillation (AF) and is associated with heightened risks of stroke/systemic embolisation and bleeding. In this review we outline the evidence for AF stroke prevention in kidney disease, identify current knowledge gaps, and give recommendations for anticoagulation at various stages of chronic kidney disease. Overall, anticoagulation is underused.

Pyopneumopericarditis from a gastropericardial fistula: a case report.

Background: Pyopneumopericarditis is a very rare diagnosis that requires prompt recognition and urgent treatment. It denotes the presence of pus and air in the pericardium with associated inflammation of the fibrous pericardial sac.

Case Summary: A 49-year-old gentleman was admitted with pyopneumoperciarditis on a background of a previous uncomplicated Roux-en-Y gastric bypass surgery performed 7 years prior.

Coronary artery ectasia presenting with ST-elevation myocardial infarction in a young indigenous man: a case report.

Background: Coronary artery ectasia (CAE) is often an incidental finding on angiography, however, patients can present with acute coronary syndrome due to a large thrombus burden requiring treatment with percutaneous coronary intervention or with emergency surgery.

Case Summary: A 26-year-old Indigenous Australian male was admitted with anterior ST-elevation myocardial infarction associated with an out of hospital ventricular fibrillation arrest. Coronary angiography demonstrated thrombotic occlusion of the proximal left anterior descending (LAD) artery with heavy thrombus burden and prominent vascular ectasia of all three coronary arteries.

Impact of Side-Branch Predilation on Angiographic Outcomes in Non-Left Main Coronary Bifurcation Lesions.

Background: Despite the high prevalence of coronary bifurcation lesions in routine interventional cardiology practice, the best strategy for managing this challenging lesion subset remains debatable. Due to potential for complications, the routine practice of side-branch (SB) predilation is controversial.

Methods: An electronic search was performed of online databases up until April 2018 for studies reporting periprocedural angiographic outcomes comparing provisional main-branch stenting with and without SB predilation.

Aortic distensibility is associated with both resting and hyperemic coronary blood flow.

A large body of evidence demonstrates an independent association between arterial stiffness and prospective risk of cardiovascular events. A reduction in coronary perfusion is presumed to underscore this association; however, studies confirming this are lacking. This study compared invasive measures of coronary blood flow (CBF) with cardiac magnetic resonance (CMR)-derived aortic distensibility (AD).
