Debate: Intervention on the mitral and the tricuspid valves. Perspective from surgery

REC: Interventional Cardiology (English Ed.), 2021
QUESTION: What is the current status of percutaneous coronary interventions to treat functional mitral regurgitation (MR)? ANSWER: Functional MR is one of the clinical conditions within cardiology that have experienced more changes over the last few ...

Motion correction for the quantification of mitral regurgitation using the control volume method [PDF]

Magnetic Resonance in Medicine, 2000
Quantifying mitral regurgitation is difficult because of the complexity of the flow, geometry and motion of the mitral valve. In this paper a MRI compatible phantom was built incorporating a left ventricle and mitral valve motion. Valve motion was obtained using a pneumatic piston.

Left Atrial Overload Can Be Used to Estimate Mitral Regurgitant Volume [PDF]

Congestive Heart Failure, 2001
This study was conducted to assess the accuracy of the estimated mitral regurgitant volume using both the left atrial filling volume and the systolic component of pulmonary vein flow expressed as the percent of its total. Since mitral regurgitation fills the left atrial chamber, the variation in atrial volume during ventricular systole has been ...

A Comprehensive Engineering Analysis of Left Heart Dynamics After MitraClip in a Functional Mitral Regurgitation Patient

Frontiers in Physiology, 2020
Percutaneous edge-to-edge mitral valve (MV) repair using MitraClip has been recently established as a treatment option for patients with heart failure and functional mitral regurgitation (MR), which significantly expands the number of patients that can ...

Impact of bileaflet mitral valve prolapse on quantification of mitral regurgitation with cardiac magnetic resonance: a single-center study

Journal of Cardiovascular Magnetic Resonance, 2017
Background To quantify mitral regurgitation (MR) with CMR, the regurgitant volume can be calculated as the difference between the left ventricular (LV) stroke volume (SV) measured with the Simpson’s method and the reference SV, i.e. the right ventricular

Quantification of regurgitation in mitral valve prolapse with four-dimensional flow cardiovascular magnetic resonance

Journal of Cardiovascular Magnetic Resonance, 2021
Background Four-dimensional cardiovascular magnetic resonance (CMR) flow assessment (4D flow) allows to derive volumetric quantitative parameters in mitral regurgitation (MR) using retrospective valve tracking.

Echocardiographic analysis of acute effects of percutaneous mitral annuloplasty on severity of secondary mitral regurgitation

ESC Heart Failure, 2020
Aims Percutaneous mitral annuloplasty (PMA) represents a new treatment option for secondary mitral regurgitation (SMR) being associated with higher morbidity and mortality.

Potential Efficacy of Multipoint Pacing in the Reduction of Mitral Regurgitation Volume: A Case Report

ESC Heart Failure, 2022
Abstract A 70-year-old woman who had cardiac sarcoidosis and severe tethering mitral regurgitation (MR) and had been implanted with a biventricular pacemaker experienced recurrent hospitalisation due to decompensated heart failure (HF).

Cardiac reverse remodeling in primary mitral regurgitation: mitral valve replacement vs. mitral valve repair

Journal of Cardiovascular Magnetic Resonance, 2023
Background When feasible, guidelines recommend mitral valve repair (MVr) over mitral valve replacement (MVR) to treat primary mitral regurgitation (MR), based upon historic outcome studies and transthoracic echocardiography (TTE) reverse remodeling ...

Quantification of primary mitral regurgitation by echocardiography: A practical appraisal

Frontiers in Cardiovascular Medicine, 2023
The accurate quantification of primary mitral regurgitation (MR) and its consequences on cardiac remodeling is of paramount importance to determine the best timing for surgery in these patients.
