Background: Modified citrus pectin (MCP) is used as a nutritional supplement that inhibits galectin-3 activity, a central player in the cardiac damage associated with different pathological situations. In fact, we have previously observed that MCP improved cardiac function in obese infarcted rats that was associated with a reduction in cardiac fibrosis. Therefore, the aim of the present study was to further explore whether this effect could involve the modulation of gene expression of ECM components and their mediators as well as whether it could affect another two mechanisms involved in cardiac damage: mitochondrial dynamics and autophagic flux.

Introduction And Aims: Tricuspid regurgitation (TR) induced by the implantation of cardiac implantable electronic devices (CIED) is an increasingly common cause of severe TR. Our aim was to describe the echocardiographic phenotypic characteristics of CIED-induced severe TR.

Methods: Retrospective cohort study that included patients with severe TR related to CIED diagnosed in the cardiac imaging unit of a Spanish tertiary hospital.

Article Synopsis
  • - The study investigated the link between galectin-3 and cardiac fibrosis in patients with acute myocardial infarction (MI), finding that higher galectin-3 levels in overweight patients correlated with more severe heart damage indicators.
  • - In obese rats experiencing MI, the treatment with modified citrus pectin (MCP) and 4-phenylbutyric acid (4-PBA) improved heart health by reducing fibrosis and stress levels, and enhancing heart function over a 4-week period.
  • - The findings suggest that galectin-3 and ER stress play crucial roles in heart fibrosis related to MI in obesity, highlighting their potential as therapeutic targets for improving cardiovascular health.

Introduction And Objectives: There is limited evidence to identify the most accurate method for measuring the mitral valve area (MVA) after percutaneous edge-to-edge mitral repair. Our objective was to evaluate the optimal method in this context and its correlation with the mean transmitral gradient.

Methods: A registry of patients undergoing percutaneous mitral repair was conducted, analyzing different methods of measuring MVA and their correlation with the mean gradient.

Article Synopsis
  • Cardiovascular disease (CVD) is the leading cause of death globally, with myocardial infarction (MI) being the most common form, resulting from insufficient oxygen supply to the heart muscle.
  • MI leads to changes in heart structure, increasing the risk of heart failure and death, making it essential to create animal models that imitate human heart disease for research and therapy development.
  • The text outlines a method for inducing MI in rats with a low mortality rate (<15%) and describes imaging techniques, like echocardiography and magnetic resonance, to assess heart structure and function, aiding both acute and chronic research studies.
