Quantification of mitral regurgitation: from traditional methods to artificial intelligence [PDF]

Cardiovascular Ultrasound
Mitral regurgitation (MR) is a common valvular disorder and associated with adverse outcomes. Echocardiography is the primary imaging modality for MR assessment; however, standard methods rely on geometric assumptions and single-frame analysis, which are

Recent Echocardiography Parameters for Predicting Better Functional Result after Mitral Valve Correction Surgery in Patients with Primary Mitral Regurgitation

Majalah Kardiologi Indonesia, 2021
Objectives We analyzed whether some echocardiographic parameters are good predictors of functional result after mitral valve correction surgery.    Background Ejection fraction was not the only parameter to decide optimal time for surgery, nor an ...

The effect of regurgitant volume on left ventricular volumes and dimensions in patients with isolated aortic or mitral regurgitation [PDF]

Journal of Cardiovascular Magnetic Resonance, 2010
Introduction The treatment of patients with aortic regurgitation (AR) or mitral regurgitation (MR) relies on the accurate assessment of the severity of the regurgitation and its effect on left ventricular (LV) size and function. CMR is an excellent tool for quantifying regurgitant volumes and LV size and function. The 2006 AHA/ACC management guidelines

Regional geometric differences between regurgitant and non‐regurgitant mitral valves in patients with coronary artery disease [PDF]

, 2023
Objective: Demonstrate that regional geometric differences exist between regurgitant and non-regurgitant mitral valves (MV's) in patients with coronary artery disease and due to the heterogenous and regional nature of ischemic remodeling in patients with

Increasing Temporal Resolution of 3D Transesophageal Ultrasound by Rigid Body Registration of Sequential, Temporally Offset Sequences [PDF]

, 2010
A description of mitral valve function requires both an accurate anatomical description of the three-dimensional (3D) structure as well as a description of the leaflets' rapid motion.
