Increased Afterload in Patients With Acute Reduction in Left Ventricular Ejection Fraction Following Mitral Valve Transcatheter Edge‐to‐Edge Repair

Echocardiography, Volume 42, Issue 2, February 2025.
Right panels: Linear regression between ΔLVEF and Δtotal SV (upper panel), and ΔEa and Δtotal SV (lower panel). Left panel: Pressure–volume loops before and after TEER according to acute reduction in LVEF. Ea, arterial elastance; LVEF, left ventricular ejection fraction; SV, stroke volume; TEER, transcatheter mitral valve edge‐to‐edge repair.

Impact of measurement location on direct mitral regurgitation quantification using four-dimensional flow cardiovascular magnetic resonance

Journal of Cardiovascular Magnetic Resonance
Background: Four-dimensional (4D) flow cardiovascular magnetic resonance (CMR) shows promise for quantifying mitral regurgitation (MR) by allowing for direct regurgitant volume (RVol) measurement using a plane precisely placed at the MR jet. However, the

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).
