POSS‐PEG‐NHS and GSH Cocrosslink DPAV to Prepare Anticalcification Bioprosthetic Scaffold With Enhanced Reendothelization, Anti‐inflammation, and Anti‐ROS

Advanced Healthcare Materials, Volume 15, Issue 30, 14 August 2026.
POSS‐PEG‐NHS and GSH cocrosslinked DPAV to prepare a multifunctional anticalcification valve substitute. This modification enhances mechanical properties, hemocompatibility, and re‐endothelialization while promoting anti‐inflammatory M2 macrophage infiltration and reducing calcification.

Evaluation of Expanded Mitral Regurgitation Grading in Patients Undergoing Transcatheter Edge-to-Edge Repair

Structural Heart
Background: An expanded tricuspid regurgitation scale has been shown to be incrementally useful in understanding the response to transcatheter therapies. A similar approach to mitral regurgitation (MR) has not been evaluated.

Nine‐Year Follow‐Up After M‐TEER for Secondary Mitral Regurgitation in a Patient With Cardiogenic Shock

Catheterization and Cardiovascular Interventions, Volume 108, Issue 2, Page 483-488, August 1, 2026.
ABSTRACT Background Transcatheter edge‐to‐edge repair (TEER) has become an established therapeutic option for patients with severe secondary mitral regurgitation (SMR). While randomized trials and registry data have reported outcomes up to 5 years, longer follow‐up data remain scarce.

Association between the proportionality of functional mitral regurgitation and survival after mitral valve operationCentral MessagePerspective

JTCVS Open
Objective: The concept of proportionate and disproportionate functional mitral regurgitation suggests that transcatheter edge-to-edge mitral repair may benefit patients with a smaller left ventricle relative to a higher regurgitant burden.

From Clinic to Computation: Multiscale Bioengineering Strategies for Durable Biological Aortic Valve Replacements

Advanced Functional Materials, Volume 36, Issue 39, 14 May 2026.
Bioprosthetic aortic valves have revolutionized the treatment of aortic stenosis, but their durability is limited by structural valve deterioration (SVD). This review focuses on the pericardial tissue at the heart of these valves, examining how its mechanical properties and calcification drive fatigue and failure.

Mitral Transcatheter Edge‐to‐Edge Repair in Patients With Advanced Heart Failure: A Single‐Center Experience and Insights Into Anatomical and Clinical Determinants of Procedural Complexity

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 ...

Estimation of Regurgitant Volume and Orifice in Aortic Regurgitation Combining CW Doppler and Parameter Estimation in a Windkessel Like Model [PDF]

, 1991
A method for noninvasive estimation of regurgitant orifice and volume in aortic regurgitation is proposed and tested in anaesthesized open chested pigs. The method can be used with noninvasive measurement of regurgitant jet velocity with continuous wave ...
