Employment of artificial intelligence for an unbiased evaluation regarding the recovery of right ventricular function after mitral valve transcatheter edge‐to‐edge repair

European Journal of Heart Failure, Volume 27, Issue 11, Page 2452-2464, November 2025.
Impact of mitral transcatheter edge‐to‐edge repair (M‐TEER) on left and right heart function. IQR, interquartile range; LA, left atrial; RVEF, right ventricular ejection fraction; sPAP, systolic pulmonary artery pressure; TAPSE, tricuspid annular plane systolic excursion. Abstract Aims Long‐standing severe mitral regurgitation (MR) leads to left atrial

Effects of afterload reduction on vena contracta width in mitral regurgitation

, 1998
Objectives. We used color Doppler flow mapping to determine whether vena contracta width (VCW) is a load-independent measure of the severity of mitral regurgitation.Background.

Performance assessment of prosthetic heart valves using orifice area formulae and the energy index method

, 1993
Valve function is commonly assessed by effective orifice area (EOA) estimates using equations derived from conservation of mass and energy. Errors have been found with the method due to difficulties in determining the valve’s coefficient of discharge (Cd)

A novel transcatheter tricuspid annuloplasty for severe tricuspid valve regurgitation via the K-clip™ system: early experience in China

Frontiers in Cardiovascular Medicine
BackgroundPatients who suffer from severe tricuspid regurgitation (TR) do not undergo standard care therapy because of the high surgical risk. As a result, safer and less invasive techniques are being sought after internationally.

First-in-Human Transcatheter Tricuspid Valve Repair in a Patient With Severely Regurgitant Tricuspid Valve

, 2015
BackgroundSevere tricuspid regurgitation is associated with poor prognosis; however, there are limited Class I indications for intervention, and high–surgical risk patients may go untreated. We report the first-in-human successful transcatheter tricuspid

A Comparative Assessment of Echocardiographic Parameters for Determining Primary Mitral Regurgitation Severity Using Magnetic Resonance Imaging as a Reference Standard.

, 2018
BACKGROUND: The American Society of Echocardiography (ASE) guidelines suggest the use of several echocardiographic methods to assess mitral regurgitation severity using an integrated approach, without guidance as to the weighting of each parameter.

B-type natriuretic peptide as an index of symptoms and severity of chronic rheumatic mitral regurgitation

Heart Views, 2016
Background: The most common causes of severe mitral regurgitation (MR) in developing countries are rheumatic heart disease. The plasma level of B-type natriuretic peptide (BNP) is known to increase with left ventricular (LV) dysfunction. Aim of the Work:
