What is the clinical evidence from this study?

Study design: Cohort. Population: Mitral valve replacement (n=65). Intervention: Chordal preservation vs. Chordal resection. Primary outcome: Clinical, electrocardiographic, and echocardiographic benefits.

What does this research mean for the field?

Preservation of subvalvular chordal structures during mitral valve replacement results in greater clinical and echocardiographic improvement and fewer postoperative arrhythmias compared to chordal resection. Novelty: ClaimNovelty.INCREMENTAL. Consensus alignment: ConsensusAlignment.NEUTRAL.

Does chordal preservation during mitral valve replacement improve echocardiographic and clinical outcomes compared to chordal resection in patients undergoing MVR?

Population

65 consecutive patients undergoing mitral valve replacement, evaluated in the early postoperative course.

Exposure

Mitral valve replacement with preservation of the mitral subvalvular structures (chordal preservation) (n=42)

Comparator

Mitral valve replacement with excision/resection of the mitral subvalvular structures (n=23)

Outcome

Echocardiographic dimensions (left-atrial and -ventricular diameters, right-ventricular diameters and left-ventricular length) and clinical benefits in the early postoperative coursesurrogate

Preservation of the subvalvular structures during mitral valve replacement provides greater echocardiographic and clinical benefits, including fewer arrhythmias, compared to complete resection.

Straub et al. (1994) conducted a cohort in Mitral valve replacement (n=65). Chordal preservation vs. Chordal resection was evaluated on Clinical, electrocardiographic, and echocardiographic benefits. Chordal preservation during mitral valve replacement provided greater clinical and echocardiographic benefits and fewer arrhythmias compared to chordal resection.
