ABSTRACT
Objective To summarize the experience of application of artificial chordae transplantation in mitral valve repair.Methods One hundred and five patients with mitral regurgitation due to mitral degeneration,underwent mitral valve repair with artificial chordae transplantation.Operative technique included simple Gore-Tex artificial chordae transplantation in 25 cases,artificial chordae transplantation plus quadrangular resection of the posterior leaflet in 67 cases,artificial chordae transplantation plus quadrangular resection of the posterior leaflet and Sliding technique in 13 cases.Results No early death occurred after operation.The postoperative complications were caused in 30 patients including sinus bradycardia in 8 cases,supraventricular tachycardia in 20 cases,late cardiac tamponade in onecase,pacemarker implantation in one case.Hospital time was 9-21 (14 ±4) d.Follow-up was done to 96 patients for 3 months to 5 years with a follow-up rate of 91.4%(96/105).Among 96 cases,one died of cerebral infarction after 13 months,one died from accident while the remaining were alive,74 cases were with cardiac function (NYHA) of grade Ⅰ and 20 cases with grade Ⅱ.No regurgitation was found in 92 cases,mild regurgitation in 2 cases.There were no artificial chordae ruptures.Conclusions The key to improve the early and midterm results of artificial chordae transplantation are to choose patients strictly,to grasp proper surgical skills,to do a good job in intraoperative shaping effect evaluation and the myocardial protection during extracorporeal circulation.
