Background: In developing countries, rheumatic mitral valve stenosis (MS) is still a problem and its progression leads to left atrial (LA) damage. Due to the complexity of the LA geometry, currently used techniques like antero-posterior dimension (LAD) and 2D echo derived LA volume (LAV) have several limitations that are corrected by 3D derived LA volumes in addition to functional evaluation.
Purpose: To assess the LA functions using 2D speckle tracking echocardiography and 3D transthoracic echocardiography in patients with clinically significant MS in comparison to normal healthy subjects.
Background: Stroke is a leading cause of death/disability, with notable differences in incidence, prevalence, and mortality observed. Despite advancement in stroke research, notable gaps persist in understanding the overall trend and sex-specific disparities in stroke burden over the past three decades, both in the United States of America (USA) and globally.
Aims: This observational-study aims to investigate evolving trends and sex-specific disparities in the incidence, prevalence, and mortality of stroke in the USA and globally from 1990 to 2021.
Rare diseases are collectively common, affecting approximately one in twenty individuals worldwide. In recent years, rapid progress has been made in rare disease diagnostics due to advances in DNA sequencing, development of new computational and experimental approaches to prioritize genes and genetic variants, and increased global exchange of clinical and genetic data. However, more than half of individuals suspected to have a rare disease lack a genetic diagnosis.
