Summary

This study compares two surgical techniques to fix a leaky mitral valve caused by degenerative disease. One method replaces the tiny chords that support the valve, while the other moves existing chords to a better position. The trial will follow 64 adults for one year after surgery to see which approach reduces leakage more effectively.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance: Mitral valve chordae prosthesis and chordae translocation (surgical procedures)
What this could lead to: If successful, this study could show which surgical method is more effective at repairing the mitral valve and reducing leakage long-term.
What could go wrong: This is a small, single-center study with only 64 participants, so results may not apply to all patients. Surgery always carries risks like infection or bleeding.
