Key result
Chordal-sparing MVR with oblique resuspension linked to a ~7% higher late versus early postoperative LVEF.
Why the study?
In patients with mitral stenosis, diseased chordae tendineae often require replacement with artificial chordae to achieve chordal-sparing mitral valve replacement.
Does chordal-sparing mitral valve replacement with oblique resuspension of artificial chordae tendineae preserve left ventricular function in patients with rheumatic mitral stenosis?
Population

Does chordal-sparing mitral valve replacement with oblique resuspension of artificial chordae tendineae preserve left ventricular function in patients with rheumatic mitral stenosis?
Absolute Event Rate: 68% vs 61%
p-value: p=< 0.01
Chordal-sparing mitral valve replacement with oblique resuspension of artificial chordae tendineae in rheumatic mitral stenosis preserves long-term left ventricular ejection fraction comparable to preoperative levels.
Soga et al. (2002) conducted an observational in Rheumatic mitral stenosis (n=17). Chordal-sparing mitral valve replacement with oblique resuspension vs. Early postoperative period was evaluated on Left ventricular ejection fraction (p=< 0.01). Chordal-sparing mitral valve replacement with oblique resuspension improved late postoperative left ventricular ejection fraction compared to the early postoperative period (68% vs 61%, p<0.01).
