A simple technique for preparation of artificial chordal loops with a strip of paper.

Artificial chordal replacement with polytetrafluoroethylene suture lines is a well-accepted technique for mitral valve repair. This report presents a method of making chordal loops of the desired length using a strip of paper. This technique uses a simple, cost-free, and easily obtained material--a strip of paper--to prepare artificial chordal loops with its advantages.
