The right ventricle systolic force ratio could predict the severity of the tricuspid regurgitation-RIVIERA ratio.

Purpose: For assessing the severity of tricuspid regurgitation (TR), there is no gold standard. We developed a parameter, the right ventricular systolic force ratio-RIVIERA, using the continious wave Doppler analysis of TR and pulsed-wave analysis of the right ventricle outflow tract. We hypothesized that the RIVIERA would facilitate the ability to identify severe TR in clinical settings.

Evaluation of Endothelial Dysfunction in COVID-19 With Flow-Mediated Dilatation.

Background: Inflammation is known to play a crucial role in many diseases, including COVID-19.

Objective: Using flow-mediated dilatation (FMD), we aimed to assess the effects of inflammation on endothelial function in COVID-19 patients.

Methods: This study was conducted with a total of 161 subjects, of whom 80 were diagnosed with COVID-19 within the last six months (comprising 48 women and 32 men with a mean age of 32.

Assessment of Aortic Stiffness by Transthoracic Echocardiographic in Young COVID-19 Patients.

Background: Deteriorated aortic elasticity is part of the atherosclerotic process. Inflammation is an underlying factor in both COVID-19 and atherosclerosis.

Aims And Objectives: Using aortic elastic properties, we aimed to assess the subclinical indicators of susceptibility to inflammatory atherosclerosis in patients with COVID-19.
