Mitral valve repair in barlow disease: complete semirigid rings vs flexible posterior annulloplasty band (randomized study)
Objective: to compare intermediate and early results after mitral valve repair using complete ring and posterior annuloplasty band in patients with Barlow disease. Since 09.2011 till 03.2013 we perform 41 mitral valve repairs in Barlow disease (repair rate 92,7%). Data is collecting prospectively; all patients have been randomized into following groups: annuloplasty with complete rings (20patients) or posterior band (21patients). Mean age were 48,9±12,0 and 52,7±10,9 years respectively. Both groups were comparable for age, sex, height, weight, BMI, BSA, NYHA functional class, LV EF, heart rhythm. There is no hospital mortality. Mean follow up 13,4±4,5 months. In both groups at discharge were significant LA reduction, LV end systolic and diastolic dimension decrease, LV end systolic and diastolic volume decrease. There was no statistically significant difference in pre- and postoperative period from one group to another. At latest follow up mitral regurgitation were 1,2±0,9 and 0,7±0,5 respectively. Freedom from reoperation were 100% in both groups. All patients were free from acute myocardial infarction, transient ischemic attack, stroke, bleeding, endocarditis. In one patient (group I) ring dehiscence were find. Complete ring and posterior annuloplasty band implantation in patients with Barlow disease have comparable results at discharge.
