ABSTRACT
<p><b>OBJECTIVE</b>To study the clinical results of mitral valve repair in patients of primary infective endocarditis with mitral insufficiency.</p><p><b>METHODS</b>From January 2004 to July 2007, 40 patients who had undergone valve repair procedure for infective endocarditis with mitral insufficiency were analyzed retrospectively. There were 26 male and 14 female patients, with an average age of (34.0 +/- 3.5) years old, including 6 patients of underlying heart disease, 34 patients of no previously underlying heart disease. There were 12 patients in NYHA functional class II, 19 patients in class III, 9 patients in class IV preoperatively. Preoperative echocardiography showed moderate to severe MR in all patients. The surgery was performed under extracorporeal circulation and moderate hypothermia. The distribution of anatomical lesion according to surgical findings were vegetation in 32 patients, leaflet prolapsed in 34 patients, leaflet perforation in 16 patients, chordal rupture in 32 patients, and annular abscess in 2 patients. The vegetations and infected tissues were debrided. The surgery consisted of complex methods to repair mitral valve, including direction leaflet closure in 5 patients, pericardial patch closure of leaflet perforation in 18 patients, chords reimplantation in 4 patients and chords transference in 6 patients, quadrangular resection in 12 patients, double orifice method in 17, closure of the commissure in 8, rings annuloplasty in 28 cases, and so on. There were 28 selective surgeries and 12 emergent ones. Patients were evaluated for early and long-term clinic and echocardiographic outcome before and after operation.</p><p><b>RESULTS</b>There were no early postoperative death. Mitral valve repair was feasible in 39 patients, one patient was transformed to mitral valve replacement during the operation. Postoperative echocardiography demonstrated no (n = 24) or mild (n = 15) mitral regurgitation at the discharge examination and observed significant reductions in left ventricular end diastolic [from (62 +/- 7) mm to (51 +/- 6) mm, P < 0.05] and end systolic dimensions [from (45 +/- 3) mm to (40 +/- 4) mm, P < 0.05] and left atrial dimensions [from (49 +/- 4) mm to (42 +/- 6) mm, P < 0.05]. Mean follow-up (25.6 +/- 3.2) months, freedom from recurrent moderate to severe MR, freedom from repeat operation or infective endocarditis, revealed patients were 36 cases in NYHY class I, 3 cases in class II.</p><p><b>CONCLUSION</b>Mitral valve repair for mitral valve endocarditis is feasible with a satisfied clinical outcome, maintains valve competency with significant reductions in left atrial and left ventricular dimensions after surgery.</p>
