OBJECTIVE: We compared the midterm results of mitral valve repair with and without leaflet resection, and revealed the effectiveness of this technique, even for in the posterior leaflet alone. PATIENTS: From August 2002 to March 2014, a total of 306 mitral valve repairs were carried out at our hospital. Of these patients, 50 cases did not undergo leaflet resection (Artificial Chordae; Group A) and 56 cases underwent leaflet resection (Resectional; Group R). There were no significant differences in the preoperative profiles. RESULTS: The follow up rate was 98% and 100% respectively. The mean cardiopulmonary bypass time and aortic cross clamp time were not significantly different. The average ring size was significantly larger (p <0.01) in Group A. All cause mortality at 3 years and 8 years was both 97.8% in Group A and was both 98.1% in Group R. Freedom from moderate mitral regurgitation at 3 years was 97.1% and at 8 years was 91.7% in Group A and 97.4% and 94.6% in Group R respectively. There were no cases of mortality, re-operation for recurrent mitral regurgitation, hemolytic anemia and infectious endocarditis. CONCLUSION: We demonstrated good midterm results in mitral valve repair without leaflet resection. However, further follow-up was needed.
