Supra-annular valve replacement is a viable technique for infants with a small valve annulus. Here, we report two infants who underwent mitral valve replacement via the supra-annular technique. The age and body weight of these babies were 2 months and 3 months and 4.1 kg and 4.7 kg, respectively. Aortic mechanical valves were reversely implanted with a short segment of PTFE graft. The purpose of this strategy was to insert a larger mechanical valve and delay resternotomy. A two-year follow-up exam showed normal ventricular function without mechanical valve-related complications. This method is useful in treating neonates and infants.</span></p><p class="p1"><span class="s1">Although the technique of mitral valve repair has improved over several decades, mitral valve replacement still is necessary at times. In neonates and infants with a small annulus, implantation of commercially available prosthetic valves in the annular position can be a challenge, and an age less than 1 year is a risk factor for early death [Selamet 2008]. Supra-annular mitral valve replacement (SMVR) is an alternative when a traditional annular implantation is not feasible [Sung 2008]. Herein, we report the cases of two patients, who underwent SMVR with a follow-up after two years.</span></p> ER -
