ObjectiveTo evaluate the effectiveness of mitral valve repair for mitral regurgitation. MethodsWe retrospectively analyzed the clinical data of 47 patients underwent mitral repair in General Hospital of Ningxia Medical University between January 2010 and June 2014 year. There were 36 males and 11 females with age of 10 months to 65 years, mean age of 42.38±15.27 years. ResultsThere was no operative death within follow-up time of 18±7 months (ranged 14 to 1 586 days). Mitral valve function was normal or traces regurgitation in 33 patients (70.21%). Mild mitral regurgitation occurred in 11 patients (23.40%). Postoperative transesophageal echocardiography showed that 2 patients (4.26%) had moderate regurgitation. They underwent mitral valve repair again and cured. One patient (2.13%) underwent mitral valve replacement because of moderate to severe regurgitation. The dimensions of left atrium and left ventricle obviously decreased and heart function improved significantly compared with preoperative ones. ConclusionStrict control of surgical indications for different valve disease, the use of mitral valve repair technique, mitral surgery can get a good clinical efficacy. Preoperative diagnosis by transesophageal echocardiography, intraoperative monitoring, and immediate postoperative assessment for mitral valve repair results provide good technical support.
