Abstract：Objective To conclude the experience of mitral valve repair with autologous pericardial band and assess the clinical efficacy.Methods The clinical data of 169 patients were retrospectively reviewed,including 102 males and 67 females with mitral valve regurgitation,underwent mitral valve repair with autologous pericardial band from November 2011 to September 2015 in WuHan Aisa Heart Hospital.The age of these patients ranged from 20-79(47.5-± 10.5)years.The echocardiography showed that the preoperative degree of mitral valve regurgitation were moderate in 32 cases,severe in 137 cases.All procedures were performed under moderate hypotherrnia and cardiopulmonary bypass,mitral valve were repaired and annuloplasty were performed with autologous pericardial band.The outcome of mitral valvuloplasty was evaluated by affusion test and transesophagus echocardiography intraoperatively.Results The mean cardiopulmonary bypass and mean clamp time were (120.6±30.3)minutes and (65.6±15.7)minutes.There were 3 periopearative deaths,one patient died of low cardiac output syndrome (LCOS),one patient died of multiple organ failure,the other died of sepsis.Before discharged hospital,the results of echocardiography showed that there is no mitral valve regurgitation in 99 patients,trivial in 43 patients,mild in 22 patients and moderate in 2 patients.No one have mitral stenosis or systolic anterior motion (SAM).150 (90.3％)patients were followed up from 12 months to 40 months.During follow-up,2 patients were death,one died of no-cardiac cause;3 patients underwent mitral valve replacement.left atrium size (LA) and left ventricular end diastolic volume(LEVED) decreased significantly than preoperative respectively(P＜0.05).The rest of patients had their cardiac function improved apparently (112 patients were in New York Heart Association class Ⅰ,33 patients in class Ⅱ).Conclusion Application of autologous pericardial band in mitral valve repair is simple,safe and effective for treating mitral valve regurgitation and it could restore the left ventricular function with early good results.
