Silk Fibroin for Cardiovascular Medical Devices: Review of Material Properties, Applications, and Clinical Potential

Advanced NanoBiomed Research, EarlyView.
Silk fibroin is an attractive natural biomaterial that can be engineered into diverse cardiovascular constructs, including vascular grafts, cardiac patches, heart valves, and stent coatings. Its tunable biological and mechanical properties have driven substantial preclinical progress; however, widespread clinical translation in cardiovascular ...

Hyperbranched poly‐L‐lysine surface‐engineered bioprosthetic heart valves with anti‐calcification, anti‐infection, and durability

BMEMat, EarlyView.
The challenges of bioprosthetic heart valves (BHV) with respect to calcification, infection, and poor durability are tackled by surface engineering of hyperbranched poly‐L‐lysine (HBPL), providing a translational solution to improve long‐term valve performance.

An Ascorbic‐Acid Containing Poly(Carbonate) Urethane With Antioxidant Bioactivity for Application in Heart Valve Scaffold Development

Journal of Biomedical Materials Research Part A, Volume 114, Issue 11, November 2026.
ABSTRACT Prosthetic heart valve development consists of several branching, innovative strategies to mediate the complex native environment that wears down valve durability. Anti‐calcification treatments are being applied to pericardial tissue, durable polymers are being developed that mitigate oxidative degradation and stress cracking, and heart valve ...

Cardiovascular Magnetic Resonance for Direct Assessment of Anatomic Regurgitant Orifice in Mitral Regurgitation

, 2008
Background-In patients with mitral regurgitation (MR), assessment of the severity of valvular dysfunction is crucial. Recently, regurgitant orifice area has been proposed as the most useful indicator of the severity of MR. The purpose of our study was to

Spontaneous Reduction in Mitral Valve Regurgitation in Three Dogs With Severe Myxomatous Mitral Valve Disease: An Unusual Case Report

Veterinary Medicine and Science, Volume 12, Issue 6, November 2026.
In dogs with MMVD, severe valvular degeneration with chordae tendineae rupture is generally associated with a poor prognosis despite medical management. These three cases demonstrate spontaneous reduction in mitral regurgitation accompanied by decreased coaptation gap, reduced regurgitant volume, reverse cardiac remodelling, discontinuation of ...

Interventional Mitral Valve Edge‐to‐Edge Repair in Patients Above 85 Years of Age

Catheterization and Cardiovascular Interventions, Volume 108, Issue 4, Page 1548-1557, October 1, 2026.
ABSTRACT Background Mitral valve transcatheter‐edge‐to‐edge repair (M‐TEER) is routinely performed in patients with severe mitral regurgitation (MR) at high operative risk, frequently including elderly patients. Patients ≥ 85 years, however, are frequently excluded in clinical studies.

A three-dimensional insight into the complexity of flow convergence in mitral regurgitation: adjunctive benefit of anatomic regurgitant orifice area

, 2011
Mitral effective regurgitant orifice area (EROA) using the flow convergence (FC) method is used to quantify the severity of mitral regurgitation (MR). However, it is challenging and prone to interobserver variability in complex valvular pathology.

When Myocardial Injury in Lupus Is Not Lupus: Probable Antimalarial‐Associated Cardiomyopathy Mimicking Lupus Myocarditis

Clinical Case Reports, Volume 14, Issue 9, September 2026.
ABSTRACT Antimalarial cardiotoxicity may mimic lupus myocarditis in systemic lupus erythematosus. We report a 53‐year‐old woman with chronic antimalarial exposure, myocardial injury, biventricular dysfunction, electrical abnormalities, low lupus activity, and no myocardial edema.

Palliative Debulking of an Aortic Body Tumour With Right Atrial Invasion in a Dog Under Partial Cardiopulmonary Bypass

Veterinary Medicine and Science, Volume 12, Issue 5, September 2026.
This report describes a French Bulldog that developed severe right‐sided congestive heart failure due to mechanical obstruction of venous return by a heart‐base tumor extending into the right atrium. Partial cardiopulmonary bypass‐assisted palliative debulking relieved the obstruction and temporarily improved clinical signs and ascites.

Morphological evaluation of a regurgitant orifice by 3-D echocardiography: applications in the quantification of valvular regurgitation

, 1999
The clinical evaluation of blood flow regurgitation through a heart valve or stenotic lesion is an unresolved problem. The proximal flowfield region has been the study focus in the last few years; however, investigators have failed to identify an ...
