Abstract: An enlarged cardiac valve annulus can be reduced in diameter using a cord that is affixed to the annulus by a set of anchors. A knot or fixed loop is disposed at a first end of the cord, and the body of the cord passes through the knot or fixed loop so as to form (a) a loop portion positioned distally beyond the knot or fixed loop and (b) a second portion that runs between the knot or fixed loop and the second end. The body of the cord can slide with respect to the knot or fixed loop. After the anchors are implanted and a bond between the anchors and the annulus is sufficiently strong, pulling the second portion in a proximal direction while holding the knot or fixed loop in place will reduce the circumference of the annulus.
