Abstract Aims Structural and fibrotic remodelling is a well-known contributor to the atrial fibrillation (AF) substrate. Epicardial adipose tissue (EAT) increasingly recognized as through electrical in atria. We aimed assess association of LA fibrosis EAT with strain function using cardiac magnetic resonance (CMR) imaging patients AF. Methods results was assessed late gadolinium enhancement CMR, fat-water separation Dixon sequence, feature tracking applied global longitudinal its three...

Stroke is a leading cause of death and disability worldwide. Atrial myopathy, including fibrosis, associated with an increased risk ischaemic stroke, but the mechanisms underlying this association are poorly understood. Fibrosis modifies myocardial structure, impairing electrical propagation tissue biomechanics, creating stagnant flow regions where clots could form. can be mapped non-invasively using late gadolinium enhancement magnetic resonance imaging (LGE-MRI). However, fibrosis maps not...

Cryptococcal meningitis is an opportunistic infection associated with altered immunity. Immunomodulatory agent use in severe coronavirus disease 2019 (COVID-19) may predispose such infections. Here, we present a 75-year-old male patient who presented fever and general status after COVID-19 developed cryptococcal meningitis. Opportunistic arise from the of immunomodulation COVID-19, especially elderly population. This article describes case extensively reviews post-COVID-19 literature,...

Left Atrial Appendage Occlusion (LAAO) is an alternative to lifelong anticoagulation in patients with atrial fibrillation.1,2 Device related thrombus (DRT) occurs 3-4% of following LAAO.3-5 We describe a case large, unique morphology DRT and review the likely cause procedural techniques mitigate this.
