    Abstract:
    BACKGROUND: The aim of this study is to report our overall experience with minimally invasive mitral valve repair for correction of severe mitral regurgitation in the setting of Barlow's disease. METHODS: Between 1999 and 2003, 48 patients with bileaflet prolapse in the context of Barlow's disease underwent minimally invasive mitral valve repair using the "edge-to-edge" technique. Mean age was 37.9 +/- 9.1 and 58% were female. Most of the patients were in New York Heart Association (NYHA) class I or II and all of them had normal left ventricular ejection fraction. RESULTS: There were no conversions to sternotomy. Mean cardiopulmonary bypass and aortic cross-clamp times were 77 +/- 16 minutes and 56 +/- 8 minutes. No in-hospital deaths and no major postoperative complications occurred. At a mean follow-up of 22.7 +/- 10.6 months, survival rate and freedom from reoperation were 100%. All patients were in NYHA class I and in sinus rhythm. No residual mitral regurgitation was detected at echocardiography in 33 (68.7%) patients and mild insufficiency was found in 15 (31.2%). The degree of satisfaction in terms of cosmesis and postoperative pain was very high and 73% of the patients were back to work and to normal activity in 4 weeks. CONCLUSIONS: Mitral insufficiency due to Barlow's disease can be effectively corrected through a minimally invasive approach by using the "edge-to-edge" technique. In our opinion, the excellent midterm results and the high degree of patients satisfaction certainly justify the adoption of this strategy in a selected group of young and active people.
