Electrocardiographic Pathological Findings Caused by the SARS-CoV-2 Virus Infection: Evidence from a Retrospective Multicenter International Cohort Longitudinal Pilot Study of 548 Subjects.

COVID-19 has threatened the capability of receiving and allocating patients in emergency departments (EDs) all over the world. This is a retrospective cohort study to explore the role of a simple procedure like an ECG to screen for the severity of COVID-19 on admission to the ED. For this study, 548 consecutive patients were enrolled in a multicenter international registry and stratified upon ECG on admission with a simple distinction between normal vs.

QTc Interval Prolongation and Life-Threatening Arrhythmias During Hospitalization in Patients With Coronavirus Disease 2019 (COVID-19): Results From a Multicenter Prospective Registry.

Background: Prolonged QTc intervals and life-threatening arrhythmias (LTA) are potential drug-induced complications previously reported with antimalarials, antivirals, and antibiotics. Our objective was to evaluate the prevalence and predictors of QTc interval prolongation and incidences of LTA during hospitalization for coronavirus disease 2019 (COVID-19) among patients with normal admission QTc.

Methods: We enrolled 110 consecutive patients in a multicenter international registry.

Three-dimensional Transesophageal Echocardiography Demonstration of Left Atrial Appendage Echocontrast Regression after 6 Months Therapy with Dabigatran and not with Warfarin.

While warfarin therapy is efficacious in treating left atrial (LA) thrombus formation in patients with nonvalvular atrial fibrillation (AF), it does not affect red cell aggregation or LA spontaneous echo-contrast in patients. In this patient with left ventricular (LV) dysfunction secondary to AF, we observed the disappearance of dense echo-contrast in the atrial appendage after therapy with dabigatran and not with well-controlled warfarin. This allowed us to analyze accurately the appendage with three-dimensional (3D) transesophageal echocardiography (TEE) excluding thrombi and to perform electrical cardioversion to obtain a significant improvement of LV function.

Evaluation of left atrial appendage function and thrombi in patients with atrial fibrillation: from transthoracic to real time 3D transesophageal echocardiography.

The detection of embolic sources in patients with atrial fibrillation (AF) is important to guide anticoagulant therapy. Two-dimensional transesophageal echocardiography (TEE) is the gold standard to study left atrial appendage (LAA) anatomy and morphology, despite some false-positive diagnosis. We hypothesized that real time 3D TEE (RT3DTEE) is superior to 2DTEE in detecting and/or excluding LAA thrombi.

Fulminant Peripartum myocarditis associated with sudden cardiac death: a case report.

Myocarditis is an inflammatory disease of myocardium, associated with nonischemic necrosis and degeneration of myocytes. Although the clinical course is rapid, myocarditis can lead to dilated cardiomyopathy with chambers dilatation and ventricular dysfunction. The pathophysiology of myocarditis in humans is not completely understood.

[Vitamin D deficiency and cardiovascular diseases].

Vitamin D deficiency is a condition that affects a high percentage of individuals of all ages. Considerable attention has been paid recently to the possible role of deficiency of this vitamin in the development of several chronic diseases, including cardiovascular and metabolic diseases. In particular, vitamin D deficiency is associated with an increase in conditions such as obesity, insulin-resistance, hypertension, diabetes, and an increased risk of death from these pathologies.
