Key result
Modified chordal-sparing mitral valve replacement resulted in an overall in-hospital mortality of 2.5% and maintained left ventricular sphericity index at 0.44-0.63 over 3.1 years.
Why the study?
Preserving the chordal apparatus is important for long-term LV function, prompting evaluation of a modified chordal-sparing MVR technique for mitral stenosis and insufficiency.
Does a modified chordal-sparing mitral valve replacement technique improve clinical and echocardiographic outcomes in patients with mitral stenosis or insufficiency?
Population

Does a modified chordal-sparing mitral valve replacement technique improve clinical and echocardiographic outcomes in patients with mitral stenosis or insufficiency?
A modified chordal-sparing mitral valve replacement technique preserving four strut chords is safe and effective for both stenotic and insufficient valves, maintaining LV geometry and improving symptoms.
DZEMESHKEVICH et al. (2022) conducted an observational in Mitral stenosis and mitral insufficiency (n=484). Modified chordal-sparing mitral valve replacement was evaluated on Overall in-hospital mortality. Modified chordal-sparing mitral valve replacement resulted in an overall in-hospital mortality of 2.5% and maintained left ventricular sphericity index at 0.44-0.63 over 3.1 years.
