Journal of Cardiothoracic Surgery 2010 5 22 http content 5 1 22 REVIEW Jdfrs JOURNAL OF CARDIOTHORACIC SURGERY Open Access Different ways to repair the mitral valve with artificial chordae a systematic review Federico Bizzarri AntonellaTudisco Massimo Ricci David Rose and Giacomo Frati Abstract Myxomatous mitral regurgitation type II Carpentier s functional classification affects about 1-2 of the population. This represents a very common indication for valve surgery resulting in a low percentage of repairs compared to replacement which is actually performed. In the last decades several methods for mitral valve repair have been developed to make the surgical feasibility easier improve the long-term follow-up thus avoiding the need for reoperations. A very interesting method is represented by the combination of various valve repair techniques depending on the involvement of the anterior posterior or both leaflets and the use of PTFE artificial chordae tendineae when excessive chordal elongation or rupture due to myxomatous degeneration co-exists. The aim of this review is to summarize the evolution of these techniques from the beginning till now. Materials and methods We performed MEDLINE and bibliographic search including 27 articles published between 1984 and 2009 regarding the different applications of mitral valve repair with implantation of artificial PTFE chordae tendinae. The key words we used were mitral repair artificial chordae. Most of the techniques we analyzed were employed to repair both leaflets. Atriotomy approach is performed in all but one technique in which an aortotomy is made too. The main difference between the techniques is in the measurement of the length of the artificial chordae. The oldest and most common method to calibrate the length of the neo-chordae consists in filling the left ventricular cavity with saline solution. Other authors elongated the prosthetic chordae trying to approximate the
