Catheterization and Cardiovascular Interventions, Volume 107, Issue 6, Page 2013-2021, May 1, 2026.ABSTRACT Background Advanced heart failure (HF) remains a clinical challenge, and mitral transcatheter edge‐to‐edge repair (M‐TEER) has emerged as a potential bridging strategy. Aims To describe the clinical outcomes of M‐TEER in a single‐center cohort of patients with advanced HF and to identify anatomical and clinical features potentially associated ...

Journal of Applied Clinical Medical Physics, Volume 27, Issue 4, April 2026.Abstract Background Fully automated diagnostic echocardiography allows for broader screening, earlier diagnosis for patients with mitral regurgitation (MR). This feasibility study developed a deep learning (DL) framework to automatically detect MR in echocardiography videos and classify regurgitation samples into central or eccentric regurgitation ...

Analysis of the Effect of Thickness on the Performance of Polymeric Heart Valves
Journal of Functional Biomaterials, 2023 Polymeric heart valves (PHVs) are a promising and more affordable alternative to mechanical heart valves (MHVs) and bioprosthetic heart valves (BHVs). Materials with good durability and biocompatibility used for PHVs have always been the research focus ...

Advanced Healthcare Materials, Volume 15, Issue 16, 24 April 2026.Percutaneous prosthetic venous valves are fabricated by embedding stents in an electrospun matrix that extends luminally to form leaflets. The design shields leaflets from hyperplastic cells, isolates struts from blood contact, and avoids discrete anchoring points.
