Clinical Presentation and Percutaneous Treatment of Hemolytic Anemia Associated With Paravalvular Leak After TAVR.

Paravalvular leak (PVL) following transcatheter aortic valve replacement (TAVR) is an established complication, albeit rarely associated with hemolytic anemia. This report details 3 cases of significant hemolytic anemia attributed to TAVR-induced PVL, each with distinct clinical presentations and manifestations. These cases underscore the diverse and occasionally subtle clinical presentation of aortic PVL-associated hemolytic anemia.

Burden of Valvular Heart Diseases in a Racially and Ethnically Diverse Population: The Bronx-Valve Registry.

Background: Valvular heart disease (VHD) is a major focus of cardiovascular medicine, but limited data are available for racial and ethnic minorities. The aim was to assess the burden and clinical correlates of VHD in a highly diverse area of the United States.

Methods And Results: Individuals with echocardiographic diagnosis of native VHD between January 2010 and December 2019 at a quaternary care health system of the Bronx (New York, USA) were included.

Racial and ethnic disparities in patients with severe tricuspid regurgitation: The Bronx-Valve registry.

Background: Severe tricuspid regurgitation (TR) is an adverse prognostic factor. The presence of potential racial/ethnic disparities in patient characteristics and outcomes remain unexplored. This study aimed to investigate the impact of race/ethnicity on the clinical course of severe TR.

Inertial spin model of flocking with position-dependent forces.

We propose an extension to the inertial spin model (ISM) of flocking and swarming. The model has been introduced to explain certain dynamic features of swarming (second sound, a lower than expected dynamic critical exponent) while preserving the mechanism for onset of order provided by the Vicsek model. The inertial spin model (ISM) has only been formulated with an imitation ("ferromagnetic") interaction between velocities.
