Summary
The NeoChord procedure offers a minimally invasive way to replace heart chords in severe mitral valve regurgitation. This technique uses 3D echocardiography for precise placement, improving patient outcomes.
Area of Science:
- Cardiovascular Surgery
- Medical Devices
- Echocardiography
Background:
- Severe degenerative mitral valve regurgitation (DMVR) often requires surgical intervention.
- Traditional surgical approaches for DMVR can be invasive.
- Chordal rupture or prolapse is a common cause of severe DMVR.
Purpose of the Study:
- To describe the NeoChord procedure, a micro-invasive, beating-heart chordal replacement technique.
- To highlight the role of 3D transesophageal echocardiography in guiding the NeoChord procedure.
- To emphasize the importance of precise neochordae placement for optimal results.
Main Methods:
- The NeoChord procedure involves trans-ventricular, beating-heart chordal replacement.
- Three-dimensional transesophageal echocardiography (3D-TEE) is used for real-time guidance.
- Image gain adjustment on 3D-TEE aids in visualizing precise neochordae placement locations.
Main Results:
- The NeoChord procedure allows for minimally invasive repair of severe DMVR.
- Accurate and equidistant neochordae placement is achievable with 3D-TEE guidance.
- Optimized image settings enhance visualization of native mitral valve structures for accurate placement.
Conclusions:
- The NeoChord procedure is an effective micro-invasive option for severe DMVR.
- 3D-TEE guidance is essential for successful and accurate chordal replacement.
- Careful neochordae placement ensures uniform stress distribution and prevents damage to existing repairs.
