Liver stiffness increases rapidly after total cavopulmonary connection and perioperative variations in some liver enzymes appear to correlate with this change. Since a true anatomical damage is known to develop gradually with Fontan circulation, early liver stiffness raise is likely due to parenchymal congestion only. Fibro-Scan can easily recognize and assess the entity of such a change. For these reasons, this diagnostic tool must be considered useful only to monitor liver stiffness changes and evolution with time, but a conventional evaluation of results, like in other acquired hepatic fibrosis, can be misleading.

In severe aortic coarctation in the neonatal period, surgical repair is required soon after clinical stabilization. Elective repair of isolated aortic coarctation is nowadays indicated at 3-6 months of life or at the time of diagnosis. At present, no single operation appears to have a clear superiority. However, during the first months of life, an extended end-to-end anastomosis is considered the best option by most authors, even though weight at operation and anatomy of the aortic arch are also significant determinants of late recoarctation. In cases of aortic arch hypoplasia, which occurs in up to 70% of neonatal and infant coarctations, especially when associated anomalies are present, surgery seems the treatment of choice. After 3 months of age and in the adult population, balloon angioplasty and stent placement are considered a suitable option. Recently, we adopted a median sternotomy approach without the use of extracorporeal circulation for the treatment of aortic coarctation with a hypoplastic aortic arch. We treated 11 patients with satisfactory results at an average follow-up of 40 months.

This prospective observational study was designed to assess the incidence of, risk factors for, and outcome of catheter-related bloodstream infection in children undergoing cardiac surgery. A staff specifically trained to handle the central venous catheters with proper aseptic techniques and an appropriate patient to medical staff ratio remain the most effective measures to prevent this infection.
