Associations between cardiac pathology and clinical, echocardiographic and electrocardiographic findings in dogs with chronic congestive heart failure

, 2010
Arterial narrowing significantly correlated with fibrosis (P < 0.0001) and with fractional shortening, an indicator of systolic function (P = 0.002). The grade of fibrosis was associated with shorter survival time (P = 0.002), and the papillary muscle

Transcatheter edge‐to‐edge repair of atrial secondary mitral regurgitation positively influences atrial remodelling

ESC Heart Failure, Volume 12, Issue 3, Page 2267-2277, June 2025.
Abstract Background Atrial secondary mitral valve regurgitation (ASMR) is a distinct anatomical subset of secondary mitral regurgitation (SMR). Evidence of the effect of transcatheter edge‐to‐edge repair (TEER) on left atrial (LA) anatomy and function, especially reverse remodelling (LARR), is still sparse.

Functional Mitral Valve Regurgitation, Pathophysiology, Leaflet ReModeling, and the Role of Imaging

Echocardiography, Volume 42, Issue 3, March 2025.
Functional mitral regurgitation (FMR) is a complex left ventricle (LV) and left atrium (LA) disorder with a multifactorial etiology. Regional and global LV dysfunction, extent and location of fibrotic myocardium and annulus enlargement are the leading causes of valve regurgitation.

Numerical simulation of the proximal convergence region of a regurgitant orifice

, 1993
The quantification of vascular regurgitation has recently focused on a new method, the method of Proximal Isovelocity Surface Area (PISA). Based on the continuity equation, the flow through a regurgitant orifice may be calculated by determining the flow ...

CT predicts intraprocedural hemodynamics with computational fluid dynamics in TMVR-ineligible patients undergoing M-TEER

Frontiers in Cardiovascular Medicine
BackgroundHemodynamic outcomes in patients undergoing transcatheter mitral edge-to-edge repair (M-TEER) are difficult to predict. Computational fluid dynamics (CFD) is frequently used in biomedical engineering to simulate blood flow patterns under ...

Evaluation of Eccentric Mitral Regurgitation Using a Modified PISA Algorithm

工程科学与技术, 2006
:The PISA (Proximal Isovelocity Surface Area) method based on the foundation of the Doppler color proximal flow convergence, has been accepted by clinic to assess the severity of the central MR (mitral regurgitation).
