Introduction:
TOP-MINI is a new micro invasive surgical procedure to treat degenerative mitral valve regurgitation due to flail/prolapse.
Hypothesis:
This prospective single centre study sought to assess the safety and effectiveness of the TOP-MINI procedure up to one year follow-up.
Methods:
Clinical and Echocardiographic outcomes were evaluated at 1, 3, 6 months and 1 year follow-up for all patients underwent TOP-MINI procedure from November 2013 to March 2015.
Procedural success was defined as residual MR≤2+ at any time.
Results:
Sixty-one patients were treated during study period. One year survival was 96.7±2.3%. Freedom from MR>2+ is shown in figure 1 Panel A, Freedom from MR>2+ according to valve anatomy (Type A isolated P2 disease, Type B posterior multisegment disease, Type C anterior or bileaflet and/or calcified disease) is shown in Figure 1 Panel B. Freedom from MR>2+ according to STS risk profile is shown in Figure 2. The trend of Echocardiographic parameters is shown in Figure 3.
Conclusions:
TOP-MINI is a safe and effective procedure at 1 year FU. Residual MR is influenced by valve anatomy showing good results in Type A and B patients. Future techniques refinements are needed in order to improve outcomes of Type C patients. The lack of annuloplasty procedure does not influence negatively left ventricle reverse remodeling.
