Frontiers in Cardiovascular Medicine, 2022 BackgroundThe presence of tricuspid regurgitation (TR) is very common in patients with concomitant left-sided valve disease. Recent studies have advocated an additional grading of massive TR that is beyond severe. The present study sought to characterize

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 ...

Use of Artificial Intelligence to Assess the Severity of Mitral Regurgitation
Инновационная медицина КубаниObjective: To develop high-accuracy neural network model for the diagnosis and prediction of the severity of mitral regurgitation as assessed by echocardiography.Materials and methods: A total of 80 patients were divided into two groups: Group 1 included

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 ...

, 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.

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.

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.

The Conundrum of Tricuspid Regurgitation Grading
Frontiers in Cardiovascular Medicine, 2018 Findings from early percutaneous tricuspid intervention trials have shown that the severity of tricuspid regurgitation (TR) far exceeded the current definition of severe TR.

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.

, 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
