Extensive use of polytetrafluoroethylene artificial grafts for prolapse of bilateral mitral leaflets

Abstract

Because replacement of artificial chordae was not complicated and seemed to preserve fine relationships among leaflet tissues, chordae, and papillary muscles, we therefore suggest that the extensive use of PTFE artificial chordae appears to be a promising procedure for the repair of all kinds of mitral lesions causing mitral regurgitation.

Surgical Application for a Prolapse of the Anterior Mitral Leaflet by Replacing Artificial Chordae with Polytetrafluoroethylene Grafts

“…We reconfirmed that PTFE sutures are suitable for an artificial chordae repair and for an extended operative application for a BML prolapse, and we started to use this technique as the initial treatment for AML prolapse in 1991. Our results show the chordal replacement technique to be applicable for the repair of all types of BML prolapse, 11 AML prolapse, and PML prolapse.…”

“…11,13,14 Myocardial protection was provided by topical cooling and intermittent cold crystalloid cardioplegic solution (Kyushu University Solution). 15 The approach to the mitral valve was through a superior trans-septal approach.…”

“…Flail segment was described as the proportion of the AML as previously described. 11 Subsequently, we performed mitral valve repair by chordal replacement followed by mitral annuloplasty. The prolased AML was not resected.…”

“…[5][6][7][8][9][10] Similarly, we have also reported our experience in repairing a BML prolapse. 11 However, the actual limitations of chordal replacement with ePTFE sutures for prolapse of the AML have not yet been documented. For the repair of AML prolapse, we herein report our surgical challenge in performing artificial chordal reconstruction without leaflet resection.…”

Artificial chordae for pediatric mitral and tricuspid valve repair☆

“…Gore and Associates, Flagstaff, AZ, USA) chordae for mitral valve repair in adults were first reported by David in 1989 and by Frater a year later [1,2]. Since then further studies have reported good mid-and long-term results of mitral valve repair in adults using this technique [3][4][5]. Goretex neochordae are now widely accepted for mitral valve surgery in the adult.…”
