Abstract

The use of sutures as artificial chordae is widely established in mitral valve reconstruction. After the correct length of the chordae is determined by saline injection, there is a variety of methods to secure that length before tying surgical knots. We investigated the amount of damage posed by applying a haemoclip or a pean clamp and by using a knot-pusher. No differences in breaking forces were found, if a pean clamp was applied, with or without the use of a knot-pusher. (control group: 36 ± 4.4N; Pean: 37.5 ± 4.7N; control group ± knotpusher:38.6 ± 5N; pean + knot-pusher: 37.5 ± 4.2N). Using a haemoclip significantly decreased the breaking forces to 12.9 ± 14.6N compared to control group (p<0.01). The length can be safely secured by applying a pean clamp. Haemoclips should not be used on artificial chordae.
