1. A chordal replacement system comprising:
first needles attached to opposing ends of a monolithic first suture, second needles attached to opposing ends of a monolithic second suture, and third needles attached to opposing ends of a monolithic third suture, wherein the first suture is not monolithic with either of the second and third sutures;
a pledget having opposing first and second sidewalls;
wherein (a) the first suture is configurable to form a first suture loop, (b) the second suture is knotted to form a second suture loop that directly connects to the second sidewall, and (c) the third suture is knotted to form a third suture loop that directly connects to the second sidewall;
wherein neither of the second or third suture loops passes through the pledget;
wherein the first sidewall directly contacts the first suture;
wherein: (a) the second suture loop and a knot of the second suture are monolithic with one another and constitute a single suture, and (b) the knot of the second suture couples the second suture loop to the second needles.
