Abstract:
Objective To prospectively evaluate the mid-term results of mitral annuloplasty using autologous pericardium for mitral valve insufficiency.Methods From April 2004 to December 2011,48 patients underwent mitral annuloplasty using autologous pericardium,the average length of pericardial strips was (51.9 ±2.8)cm.Carpentier classification was class Ⅰ in 5 cases,class Ⅱ in 41 cases,and class Ⅲ in 2 cases.The mitral valve repair techniques included quadrangular resection in 30 cases,valve repair in 7 cases,chordae transposition in 4 cases,edge to edge technique in 2cases,and artificial chordae tendineae in 3 cases.Concomitant procedures included one case arotic valve replacement,11 cases tricuspid valve repair,9 cases coronary artery bypass grafting,1 case coronary artery muscle bridge resection,and 1 case permanent pacemaker implant.Datum on long-term outcomes were obtained by questionnaires and by phone interview [average follow-up time (62.2 ± 21.3) months].Results Compared with preoperative datum,the diameters of left ventricular end diastolic diameter (LVDD) and left atrial diameter (LAD) examined by echocardiography show significant reduction in postoperative [(58.6 ± 1.7) mm vs (45.1 ± 1.3) ram,t =12.85,P ＜0.01 ; (50.6 ± 1.6)mm vs (38.0 ± 1.4)ram,t =9.58,P ＜0.01].There was early postoperative death in one case,cerebral infarction in one case,but none of patients died in late postoperative period.One patient had moderate mitral valve regurgitation in long-term follow-up.None of patients had redo operation and hemolytic complications.Conclusions Mitral annuloplasty using an autologous pericardium was an acceptable technique with low anticoagulation complications,permanent,well left ventricular function maintenance,and an economic method.
