# Case Report: Surgical repair of mitral prolapse caused by papillary muscle elongation using premeasured artificial chordae: a case series

## TL;DR

This case series describes using premeasured artificial chordae to repair mitral prolapse caused by elongated papillary muscles, emphasizing the restoration of normal valve structures.

## Contribution

The study introduces the use of premeasured artificial chordae to improve mitral valve repair outcomes in cases of papillary muscle elongation.

## Key findings

- Premeasured artificial chordae were successfully used in 14 cases of mitral prolapse.
- Restoring physiological sub-valvular structures is emphasized for better repair outcomes.

## Abstract

Artificial chordae are increasingly used to repair mitral prolapse. The application of premeasured artificial chordae facilitates the creation of chordae with an appropriate length. Herein, we describe our experience of applying premeasured artificial chordae in 14 cases of mitral prolapse caused by elongated papillary muscles, with an emphasis on the importance of restoring the physiological features of sub-valvular structures during mitral valve repair.
