Functional Electrographic Flow Patterns in Patients with Persistent Atrial Fibrillation Predict Outcome of Catheter Ablation
Aims: Electrographic flow (EGF) mapping is a method to detect action potential sources within the atria. In a double-blinded retrospective study we evaluated whether sources detected by EGF are related to procedural outcome. Methods: EGF maps were retrospectively generated using the Ablamap® software from unipolar data recorded with a 64-pole basket catheter from patients who previously ...

What is heart failure with preserved ejection fraction (HFpEF)?
Overview What is HFpEF? Heart failure with preserved ejection fraction (HFpEF) is a clinical syndrome in which patients have signs and symptoms of HF as the result of high left ventricular (LV) filling pressure, despite normal or near-normal LV ejection fraction (EF). Most patients with HFpEF also display normal LV volumes and an abnormal diastolic filling pattern (i.e, diastolic ...

What causes heart failure with preserved ejection fraction (HFpEF)?
Heart failure with preserved ejection fraction (HFpEF) is a multifactorial and multisystemic disorder that represents more than 50% of all heart failure cases.[1] Epidemiologic data from the Framingham Study, an international cohort study, shows a rapid increase in the prevalence of HFpEF over the past three decades, from 41% to 56% and, conversely, a decrease in the prevalence of HFrEF from 44% ...
