Minimal technical modifications of the conduction of the operation were introduced during the study period. Currently, valve repair is routinely carried out through a conventional midline sternotomy, in normothermic cardiopulmonary by-pass, using intermittent normothermic blood cardioplegia. Mitral valve is approached through the left atrium, with the incision done in the interatrial groove.
Following the identification of the prolapsing portion of a leaflet, this is resuspended suturing its free edge to the corresponding edge of the opposing leaflet, usually with a figure of eight stitch using a 5–0 polypropylene suture, additional mattress sutures reinforced with pericardial pledgets are usually placed in case of thin leaflets (Fig. 1 ). When the prolapse is in the middle portion of a leaflet, the correction creates a double orifice valve, while, in case of commissural lesions, the correction simply results in a valve with a smaller orifice area (paracommissural repair).
