	Introduction

 
Obtaining the exact length of artificial chordae used in the surgery of anterior mitral valve prolapse can be difficult. In this report, a simple, reproducible method of artificial chordae implantation is described using a single loop technique.

	Surgical Technique

 
A horizontal mattress suture with pledget-supported CV-4 polytetrafluoroethylene (PTFE; Gore-Tex suture; W. L. Gore & Associates, Inc, Flagstaff, Ariz) is initially placed through the fibrous thickened part of the appropriate papillary muscle. Both ends of the suture are then passed through the prolapsing scallop 3 to 5 mm from the free edge of the leaflet from the ventricular side to the atrial side (Figure 1, A ). The greater distance from the free edge is used when there is an excessive amount of tissue, as this produces a rolling effect that reduces the leaflet length and the risk of systolic anterior motion of the mitral valve. One of the suture ends is then passed through the leaflet edge again from ventricular side to atrial side to produce a single loop (Figure 1, A). Additional PTFE sutures are implanted as appropriate . . . [Full Text of this Article]
