title: The "loop with anchor" technique to repair mitral valve prolapse.
abstract: The current surgical technique of using an artificial chord (composed of expanded polytetrafluoroethylene [ePTFE] sutures) to repair mitral prolapse is technically difficult to perform. Slippery knot tying and the difficulty of changing the chordae length after the hydrostatic test are frustrating problems. The loop technique solves the problem of slippery knot tying but not the problem of changing the chordae length. Our "loop with anchor" technique consists of the following elements: construction of an anchor at the papillary muscle; determining the loop length; tying the loop to the anchor; suturing the loop to the mitral valve; the hydrostatic test; and re-suturing or changing the loop, if needed. Adjustments can be made for the entire procedure or for a portion of the procedure.
