Review Meta AnalysisSimilar cerebral protective effectiveness of antegrade and retrograde cerebral perfusion combined with deep hypothermia circulatory arrest in aortic arch surgery: a meta-analysis and systematic review of 5060 patients.
Our objective was to determine if antegrade cerebral perfusion (ACP) and retrograde cerebral perfusion (RCP) combined with deep hypothermia circulatory arrest in aortic arch surgery results in different mortality and neurologic outcomes. ⋯ ACP and RCP provide similar cerebral protective effectiveness combined with deep hypothermia circulatory arrest and could be selected according to the actual condition in aortic arch surgery. A high-quality randomized controlled trial is urgently needed to confirm this conclusion, especially for stroke morbidity following ACP or RCP.

Multicenter Study Comparative StudyOutcomes after prolonged extracorporeal membrane oxygenation support in children with cardiac disease--Extracorporeal Life Support Organization registry study.
Extracorporeal membrane oxygenation remains the mainstay of mechanical circulatory support initiation and maintenance in children with cardiac insufficiency. However, the outcomes after prolonged extracorporeal membrane oxygenation for cardiac insufficiency in children remain ill defined. ⋯ The attrition is high after prolonged extracorporeal membrane oxygenation support for cardiac insufficiency in children. Cardiac transplantation in this cohort was rarely achieved and was associated with high mortality compared with benchmarks for cardiac transplantation survival. Earlier redirection of care or conversion to other modes of mechanical support as a bridge to transplantation should be considered.

Multicenter StudyTrends in Fontan surgery and risk factors for early adverse outcomes after Fontan surgery: the Australia and New Zealand Fontan Registry experience.
This study examined changes in practice and analyzed risk factors for adverse early outcomes after Fontan surgery through use of a binational, population-based registry. ⋯ The extracardiac conduit is now the exclusive Fontan modification performed in Australia and New Zealand. Even with a higher proportion of high-risk cases, perioperative outcomes are excellent in the modern era. Hypoplastic left heart syndrome confers a higher risk of prolonged pleural effusion and early composite adverse outcome.

ReviewSystematic review of the cost-effectiveness of transcatheter aortic valve implantation.
Transcatheter aortic valve implantation (TAVI) has emerged as an alternative treatment to aortic valve replacement (AVR) for selected patients with severe aortic stenosis. The present systematic review was conducted to analyze the cost-effectiveness of this novel technique within reimbursed healthcare systems. ⋯ Depending on the ICER threshold selected, TAVI is potentially justified on both medical and economic grounds compared with medical therapy for patients deemed to be surgically inoperable. However, in the high-risk surgical patient cohort, the evidence is currently insufficient to economically justify the use of TAVI in preference to AVR.

Multicenter Study Observational StudyTranscatheter aortic valve implantation in patients with severe aortic valve stenosis and large aortic annulus, using the self-expanding 31-mm Medtronic CoreValve prosthesis: first clinical experience.
With the introduction of the 31-mm Medtronic CoreValve prosthesis, patients with large aortic annulus have become eligible for transcatheter aortic valve implantation. The aim of this study was to evaluate the feasibility, efficacy, and safety of transcatheter aortic valve implantation using the 31-mm Medtronic CoreValve in patients with severe aortic valve stenosis and large aortic annulus. ⋯ In this retrospective multicenter registry, transcatheter treatment of severe aortic valve stenosis with the 31-mm Medtronic CoreValve seemed to be challenging, even in experienced hands. If the prosthesis is properly implanted, it offers adequate valve hemodynamics and proper functioning.
