The upside-down technique offers a novel approach for repairing posterior leaflet prolapse in the heart. This method involves in situ transposition of secondary chordae, effectively correcting leaflet defects.

Area of Science:

  • Cardiovascular Surgery
  • Cardiac Valve Repair
  • Surgical Techniques

Background:

  • Posterior leaflet prolapse is a common cause of mitral regurgitation.
  • Traditional repair methods may not be suitable for all cases, particularly those with complex anatomical challenges.

Purpose of the Study:

  • To describe the upside-down technique for in situ secondary chordae transposition.
  • To highlight its application in correcting posterior leaflet prolapse.

Main Methods:

  • The upside-down technique involves rotating a resected posterior leaflet segment.
  • Reattachment to the annulus and adjacent segments creates a new free edge.
  • Secondary chords are repositioned to function as primary chordae.

Main Results:

Related Experiment Videos

  • This method corrects segmental prolapse of the posterior mitral leaflet.
  • It transforms secondary chords into primary chordae.
  • The original annular attachment becomes the new free edge of the leaflet.

Conclusions:

  • The upside-down technique is a viable option for posterior leaflet prolapse repair.
  • It is particularly useful when quadrangular resection is not feasible.
  • Indications include calcified annulus, leaflet hypoplasia, and wide prolapsing segments.
