Comparative StudyComparison of aortic media changes in patients with bicuspid aortic valve stenosis versus bicuspid valve insufficiency and proximal aortic aneurysm.
The aim of this study was to evaluate aortic media changes in bicuspid aortic valve (BAV) patients who underwent aortic valve replacement (AVR) and simultaneous replacement of the proximal aorta for BAV stenosis vs BAV insufficiency. ⋯ Patients with BAV insufficiency and a proximal aorta of ≥50 mm have a significantly higher rate of moderate/severe EFL as compared to their counterparts with BAV stenosis.

Review Meta AnalysisA meta-analysis of randomized trials for repeat revascularization following off-pump versus on-pump coronary artery bypass grafting.
To determine whether repeat revascularization rates are increased following off-pump coronary artery bypass grafting (CABG), we performed a meta-analysis of randomized controlled trials of off-pump vs on-pump CABG. Databases including MEDLINE, EMBASE and the Cochrane Central Register of Controlled Trials were searched through March 2013 using web-based search engines (PubMed, OVID). Studies considered for inclusion met the following criteria: the design was a prospective randomized controlled clinical trial; the study population was patients undergoing CABG; patients were randomly assigned to off-pump vs on-pump CABG and outcomes included repeat revascularization rates at ≥1 year. ⋯ In general, exclusion of any single trial from the analysis did not substantively alter the overall result of our analysis. There was no evidence of significant publication bias. The results of our analysis suggest that off-pump CABG may increase repeat revascularization rates by 38% over on-pump CABG.

Randomized Controlled Trial Comparative StudyPulsatile flow decreases gaseous micro-bubble filtering properties of oxygenators without integrated arterial filters during cardiopulmonary bypass.
Cardiopulmonary bypass (CPB) has a risk of embolic injury with an important role of gaseous micro-bubbles (GMBs), coming from CPB-circuit. Pulsatile perfusion (PP) can provide specific conditions for supplementary GMB-activity with respect to non-pulsatile (NP). We aimed to test GMB-filtering properties of three modern oxygenators under pulsatile and non-pulsatile conditions. ⋯ Pulsatile flow decreases gaseous micro-bubble filtering properties of oxygenators without integrated arterial filters during CPB. PP requires specially designed circuit components to avoid the risk of additional GMB delivery.
