Mitral regurgitation detection and central/eccentric classification using transformer‐based deep learning in multi‐view echocardiography

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 ...

A Versatile Engineering Platform for the Fabrication of Prosthetic Venous Valves Using Electrospinning

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.

A Case of Isolated Congenital Double-Orifice Mitral Valve [PDF]

, 1998
Double-orifice mitral valve is a relatively rare congenital abnormality, usually discovered at autopsy or surgery. In most cases, the double-orifice mitral valve causes no hemodynamic effects, sometimes it is regurgitant, and rarely is stenotic ...

Quantitative assessment of effective regurgitant orifice: impact on risk stratification, and cut-off for severe and torrential tricuspid regurgitation grade

European Heart Journal - Cardiovascular Imaging, 2019
Abstract Aims  Asses the added value of quantitative evaluation of tricuspid regurgitation (TR), the proper cut-off value for severe TR and ‘torrential TR’ based on outcome data. The added value of quantitative evaluation of TR, and the cut-off values associated with increased mortality are unknown.

Assessment of Prevalence and Characteristics of Valvular Heart Disease: A Cross‐Sectional Study From Yazd Health Study

Health Science Reports, Volume 9, Issue 4, April 2026.
ABSTRACT Background and Aims Valvular heart diseases (VHDs) significantly contribute to global cardiovascular mortality and morbidity, with a shift in epidemiology from rheumatic heart disease (RHD) in developing nations to degenerative valvular diseases in aging populations of industrialized countries.

Color Doppler velocity accuracy proximal to regurgitant orifices: influence of orifice aspect ratio

, 1999
Many noninvasive methodologies used for the accurate evaluation of valvular regurgitation require precise velocity measurements from ultrasound instruments.

Study of Tricuspid Valve Regurgitation by 2D and 3D Echocardiography: Comparison Between Transthoracic and Transesophageal Examination for Screening Interventions

Echocardiography, Volume 43, Issue 4, April 2026.
Forty‐two patients with significant tricuspid regurgitation (TR) underwent transthoracic (TTE) and transesophageal (TEE) echocardiography. The same day wo‐dimensional (2D) and three‐dimensional (3D) parameters obtained with both modalities were compared.
