Randomized Controlled Trial Comparative Study
Randomized trial of carpentier-edwards supraannular prosthesis versus mosaic aortic prosthesis: 6 year results.
This study prospectively compares the clinical performance of 2 stented porcine aortic bioprostheses: the Carpentier-Edwards supraannular aortic valve (CE-SAV) from Edwards Lifesciences (Irvine, CA) and the Mosaic valve from Medtronic Corp (Minneapolis, MN). We believe it is the only study of this kind. ⋯ There were no statistically significant differences in the clinical performance between CE-SAV and Mosaic aortic prostheses at 6 years after implantation.

Multicenter Study Comparative Study
Impact of surgeon demographics and technique on outcomes after esophageal resections: a nationwide study.
Thoracic, cardiac, and general surgeons perform esophageal resections in the United States. This article examines the impact of surgeon subspecialty on outcomes after esophagectomy. ⋯ General surgeons perform the major proportion of esophagectomies in the United States. Surgeon subspecialty is not associated with the risk of complications developing but instead is associated with mortality and failure to rescue from complications. Surgeon subspecialty case mix is an important determinant of outcomes for patients undergoing esophagectomy.

Comparative Study
Reoperation after acute type a aortic dissection repair: a series of 104 patients.
Our objective was to analyze the causes, timing, and results of reoperation after primary repair for acute type A dissection. ⋯ More extensive acute dissection repair results in a lower rate of reoperation. Mortality for redo surgery after type A acute dissection repair is acceptable. This finding should be taken into account in proposing a widespread of more complex and extensive surgery for type A acute dissection.

Blood conservation operations in pediatric cardiac patients: a paradigm shift of blood use.
Red blood cell transfusion is associated with high morbidity in pediatric patients undergoing cardiac operations. The aim of this study was to evaluate the clinical effects and outcomes of blood conservation for our pediatric patients undergoing cardiac operations. ⋯ Blood conservation in pediatric cardiac operations is associated with fewer ventilator days, lower inotropic scores, and shorter lengths of stay. These findings, in addition to attendant risks and side effects of blood transfusion and the rising cost of safer blood products, justify blood conservation in pediatric cardiac operations.

Comparative Study
Recoarctation after the norwood I procedure for hypoplastic left heart syndrome: incidence, risk factors, and treatment options.
Early survival after the Norwood I procedure has improved over the years, but subsequent morbidity is not yet well assessed. The aim of this study was to review the incidence of recoarctation, evaluate risk factors, and analyze treatment options. ⋯ A standardized surgical technique for reconstruction of the aorta leads to a low recoarctation rate. Balloon angioplasty can be performed in the majority of patients before the second-stage procedure.
