The Sorin Pericarbon Freedom Stentless aortic valve has the potential to provide superior hemodynamic function and durability. In this study we assessed the hemodynamic performance of this valve and its impact on LV-mass regression after aortic valve replacement. ⋯ The hemodynamic performance of the Sorin Pericarbon Freedom Stentless aortic valve is excellent and the patient outcome is satisfying. However the implantation technique requires longer ischemic time, the prosthesis offers very satisfying hemodynamic function and accelerates probably the LV-mass regression in the mid term follow-up. Late performance and durability of the valve have to be assessed.

The intramedullary Kirschner wire fixation of distal metacarpal fractures reported by Foucher et al. combines the known advantages of intramedullary implants with a reduction of iatrogenic soft tissue trauma. We applied this minimal invasive internal fixation technique in 38 patients with fractures dislocated by more than 20 degrees and/or with rotatory deformity. After opening the intramedullary cavity from the base of the respective metacarpal bone and after fracture reduction, two pre-bent Kirschner wires were intramedullary inserted in an orthograde fashion. ⋯ With one exception, all fractures were healed in a proper position. The wires were removed under local anaesthesia on an outpatient basis after six to eight weeks and full mobility of the fingers was achieved in 34 patients at that time. Complications included one redislocation and one distal wire perforation.
