In 2013, we published a simple method for aortic valve reconstruction in children using fixed pericardium in this journal. This was not expected to be a durable solution but a temporizing measure in the absence of other solutions, in order to buy time for growth that would allow subsequent prosthetic valve insertion. As such, this was implemented in 3 patients with excellent immediate results, as reported in our original publication. We are now writing to provide longer term information. In 2 cases, a newborn and a 12-year-old boy, the valve calcified heavily at 4 years' follow-up. By then, the valvar annulus had grown sufficiently to accept a prosthetic valve in both cases. In these 2 cases, the material used for valve reconstruction was autologous pericardium fixed in 0.6% gluteraldehyde. In the third patient, a 3-year-old girl, the valve failed by dehiscence of the suture line 6 months following surgery. In this case, fixed bovine pericardium had been used, which is more rigid than autologous pericardium, thus possibly explaining the dehiscence. However, the pericardial patch was not calcified. Thus, the described method lived up to our expectation of buying time for growth for later insertion of a prosthetic valve in 2 of the 3 cases.
