Minimally Invasive Mitral Valve Repair With a Standardized Loop Technique
Minimally invasive mitral valve repair is accepted as a reliable technique, and its use has spread. The respect rather than resect approach is now widely used in mitral valve repair, and Gore-Tex neochordae are the cornerstone of this treatment. One of the perioperative difficulties is to adapt the length of the neochordae to a proper height. In this video, the authors present their technique for mitral repair with a standardized Gore-Tex loop. The patient was a 45-year-old female diagnosed with a severe mitral insufficiency. TOE showed an isolated prolapse of P2.
The patient was placed in the supine position and intubated with a double-lumen endotracheal tube. Defibrillator pads were placed on the chest wall and peripheral CPB was established as usual. The repair was made with Gore-Tex neochordae, handmade according to the Miami technique as described by Joseph Lamelas (1). In the authors’ experience, a 15 mm Gore-Tex loop for posterior prolapses and a 25 mm Gore-Tex loop for anterior prolapses have been adaptable for all patients.
