Cardiac reoperations following the Ross procedure in children: spectrum of surgery and reoperation results.
The Ross procedure is the preferred aortic valve replacement (AVR) choice in small children. Nonetheless, it is a complicated surgery and there are concerns that subsequent cardiac reoperations are exceptionally complex and associated with high morbidity and mortality. We examine the surgical spectrum and report outcomes of cardiac reoperations in patients who had undergone the Ross procedure during childhood. ⋯ A wide range of cardiac reoperations may be required in children following the Ross procedure, especially those with underlying rheumatic aetiology, aortic regurgitation and multivalvular involvement. Despite complexity, reoperation following the Ross procedure can be performed with low mortality and good mid-term results. This information should be taken into consideration during the selection of aortic valve substitute in children.

Comparative Study Clinical TrialMortality and neurodevelopmental outcome at 1 year of age comparing hybrid and Norwood procedures.
Neonates with hypoplastic left heart syndrome (HLHS) are at risk of high mortality and neurodevelopmental morbidity. As an alternative to Norwood-type stage I palliation, the hybrid procedure has been developed. It consists of bilateral pulmonary artery banding, catheter-based stenting of the arterial duct and balloon atrioseptostomy and delays open-heart surgery. Thus, it may be associated with a better outcome. The aim of this study was to determine the mortality and neurodevelopmental outcome in patients with HLHS and other univentricular heart (UVH) defects treated with hybrid or Norwood procedures. ⋯ Mortality at 1 year of age is comparable between patients undergoing hybrid and Norwood procedures. Early neurodevelopmental outcome is significantly impaired in patients with both HLHS and other UVH defects. Multicentre randomized studies are needed to determine the long-term neurodevelopmental outcome of children treated with the hybrid procedure.

Mid-term results of bioprosthetic pulmonary valve replacement in pulmonary regurgitation after tetralogy of Fallot repair.
Pulmonary valve replacement (PVR) is performed to reduce right ventricular (RV) volume overload, resulting in improved ventricular function and clinical status. Significant pulmonary regurgitation (PR) after tetralogy of Fallot (TOF) repair could result in RV dysfunction, exercise intolerance, arrhythmia and sudden death. The present study was conducted to investigate the mid-term clinical outcomes of PVR after TOF repair. ⋯ PVR reduced the RV volume and improved the RV function within the first postoperative year. The rate of freedom from reoperation during the 10-year follow-up period in our series was acceptable. However, a longer follow-up will be necessary to determine the long-term outcomes of bioprosthetic valves in PVR.
