For many patients with symptomatic atrial fibrillation, cardioversion is performed to restore sinus rhythm and relieve symptoms. Cardioversion carries a distinct risk for thromboembolism which has been described to be in the order of magnitude of 1 to 3 %. For almost five decades, vitamin K antagonist therapy has been the mainstay of therapy to prevent thromboembolism around the time of cardioversion although not a single prospective trial has formally established its efficacy and safety. Currently, three new direct oral anticoagulants are approved for stroke prevention in patients with non-valvular atrial fibrillation. For all three, there are data regarding its usefulness during the time of electrical or pharmacological cardioversion. Due to the ease of handling, their efficacy regarding stroke prevention, and their safety with respect to bleeding complications, the new direct oral anticoagulants are endorsed as the preferred therapy over vitamin K antagonists for stroke prevention in non-valvular atrial fibrillation including the clinical setting of elective cardioversion.

Background: Plasma NT-proBNP (N-terminal pro-B-type natriuretic peptide) is commonly used to diagnose heart failure with preserved ejection fraction (HFpEF), but its diagnostic performance in the ambulatory/outpatient setting is unknown because previous studies lacked objective reference standards.
Methods: Among patients with chronic dyspnea, diagnosis of HFpEF or noncardiac dyspnea was determined conclusively by exercise catheterization in a derivation cohort (n=414), multicenter validation cohort 1 (n=560), validation cohort 2 (n=207), and a nonobese Japanese validation cohort 3 (n=77). Optimal NT-proBNP cut points for HFpEF rule out (optimizing sensitivity) and rule in (optimizing specificity) were derived and tested, stratified by obesity and atrial fibrillation.

Background: The optimal imaging modality for selecting the device size in patients with atrial fibrillation undergoing one-stop left atrial appendage occlusion (LAAO) with concomitant pulmonary vein isolation (PVi) remains undefined. We compared preprocedural 3-dimensional computed tomography (3D CT) with intra-procedural transesophageal echocardiography (TEE) and left atrial appendage (LAA) angiography in guiding one-stage PVi and LAAO.
Methods: We measured the LAA ostium diameter using an interactive 3D CT system with a central line-based approach and compared these measurements with those from intra-procedural TEE and angiography, and the actual device size.

Background: Aortic stenosis (AS) remains a prevalent and serious global health concern, exacerbated by an aging population worldwide. This valvular disease, when symptomatic and without appropriate intervention, severe AS can drastically reduce life expectancy. In our systematic review and -analysis, we aim to synthesize available evidence to guide clinical decision-making by comparing the performance of TAVR and SAVR, specifically in patients with severe AS and a small aortic annulus.

Raynaud's phenomenon (RP) is characterized by episodic vasospasm of the small blood vessels, primarily affecting the fingers and toes. Management includes lifestyle modifications, pharmacological treatments, and in severe cases, surgical interventions. Here we report a case of an 80-year-old male patient with a history of hypertension, dyslipidemia, obesity, and atrial fibrillation who presented to the emergency department with edema, cyanosis, and intense pain in the fingers of both hands following a mild COVID-19 infection (no dyspnea or hypoxemia).
