Transcatheter Caval Implantation for Severe Tricuspid Regurgitation.

Curr Cardiol Rep

January 2025

Department of Cardiovascular Medicine, Heart Vascular & Thoracic Institute, Cleveland Clinic, 9500 Euclid Avenue, J2-3, Cleveland, OH, 44195, USA.

Purpose Of Review: We describe the evolution of caval valve implantation (CAVI) as a treatment for severe symptomatic tricuspid regurgitation (TR) in the high surgical risk patient.

Recent Findings: Surgical treatment of severe TR is often limited by the high surgical risk of the patients who tend to develop severe secondary TR. Coaptation, annuloplasty, and orthotopic replacement strategies are all limited by annular and leaflet geometry, prior valve repair, and the presence of cardiac implantable device leads.

Background: Limited data exist on the impact of polyvascular disease (PolyVD) on clinical outcomes in female patients undergoing transcatheter aortic valve replacement (TAVR). We therefore sought to investigate clinical outcomes in women with versus without PolyVD undergoing TAVR.

Methods: Female participants from the multicentre Women's International Transcatheter Aortic Valve Implantation (WIN-TAVI) registry were categorized based on the presence or absence of PolyVD.

Manganese Galvanic Cells Intervene in Tumor Metabolism to Reinforce cGAS-STING Activation for Bidirectional Synergistic Hydrogen-Immunotherapy.

Adv Mater

January 2025

Institute of Functional Nano & Soft Materials (FUNSOM), Jiangsu Key Laboratory for Carbon-Based Functional Materials & Devices, Soochow University, Suzhou, 215123, China.

The cGAS-STING pathway is pivotal in initiating antitumor immunity. However, tumor metabolism, particularly glycolysis, negatively regulates the activation of the cGAS-STING pathway. Herein, Mn galvanic cells (MnG) are prepared via liquid-phase exfoliation and in situ galvanic replacement to modulate tumor metabolism, thereby enhancing cGAS-STING activation for bidirectional synergistic H-immunotherapy.

Transcatheter aortic valve implantation (TAVI) is the main treatment option for patients with severe aortic stenosis (AS) and older age. Improved imaging techniques have enabled better patient selection, and the main role is played by echocardiography. Methods more sensitive than LVEF in assessing cardiac function, such as global longitudinal strain (GLS) and myocardial work (MW), have become widespread, and other methods, like hemodynamic forces (HDFs), might be promising.
