OBJECTIVE: Mitral valve repair is frequently performed now because it produces a favorable postoperative quality of life, as well as improved cardiac function. For the treatment of posterior leaflet prolapse, we perform a posterior mitral annuloplasty using an autologous pericardium. The present study assessed the efficacy of this operation. METHODS: From April 1999 to October 2003, 42 patients underwent a posterior mitral annuloplasty using autologous pericardium for the treatment of posterior leaflet prolapse. There were 15 men and 27 women with an average age of 63.9 +/- 11.8 years. The length of the autologous pericardium matched the length of the posterior leaflet annulus as measured with Carpentier-Edwards ring sizer that was chosen based on the area of the anterior leaflet. RESULTS: The average size of the Carpentier-Edwards ring sizer that was used to determine the length of the autologous pericardium was 27.7 +/- 13 mm, and the absolute length of the pericardium was 50.9 +/- 1.8 mm, and the average intraoperative jet area, as assessed by transesophageal echocardiography, was 0.36 +/- 0.47 cm2. The five-year freedom from reoperation was 97.1%, while the freedom from significant residual mitral regurgitation (> or = 3+/4+) was 92.0%. Two patients (4.8%) developed systolic anterior motion, and one patient (2.4%) had a cerebral infarction. None of the patients died after surgery, and no patients developed complications such as hemolysis or ring detachment. CONCLUSIONS: Posterior mitral annuloplasty using an autologous pericardium was shown to be a superior technique because it allows a sufficient annular repair with no complications such as hemolysis or ring detachment.
