Review Meta Analysis
Unilateral Versus Bilateral Antegrade Cerebral Protection During Aortic Surgery: An Updated Meta-Analysis.
In the context of complex aortic surgery, despite the wide consensus about the use of moderate hypothermia in association with antegrade selective cerebral perfusion (ASCP), its bilateral administration is not always warranted. The aim of the present meta-analysis was to investigate outcomes of unilateral versus bilateral ASCP. ⋯ Unilateral versus bilateral ASCP administration did not result in different mortality and neurologic morbidity rates. Nevertheless, among prolonged CA times unilateral ASCP resulted in poorer outcomes with respect to bilateral ASCP. Furthermore, moderate hypothermia was associated with best outcomes in both groups.

Randomized Controlled Trial
A Regulated Trial of Bicuspid Aortic Valve Repair Supported by Geometric Ring Annuloplasty.
Annular stabilization is important during bicuspid aortic valve (BAV) repair to obtain the best long-term results. This report describes the early outcomes of a novel bicuspid annuloplasty ring for this purpose. ⋯ As a technique for BAV repair, internal ring annuloplasty produces major annular remodeling and stabilization. Annular reduction and reshaping to a 50/50% symmetric circular geometry facilitates leaflet repair and enhances cusp coaptation. Geometric ring annuloplasty could have useful applications in BAV repair.

Congenital sternal cleft is a rare chest wall malformation. Because of the flexibility of the chest in infants, surgical repair should be performed by primary closure in the neonatal period. In adolescents and adults, different techniques have been suggested to overcome the lack of sternal bone tissue. We describe a very rare case of an 18-year-old woman with a complete bifid sternum associated with pectus excavatum for whom a satisfactory cosmetic and functional result was obtained by adequate surgical planning, which entailed a combination of two standardized surgical techniques.
