Comparative StudyThe impact of temperature in aortic arch surgery patients receiving antegrade cerebral perfusion for >30 minutes: How relevant is it really?
We examined the early outcomes and the long-term survival associated with different degrees of hypothermia in patients who received antegrade cerebral perfusion (ACP) for >30 minutes. ⋯ In proximal and arch operations involving ACP for >30 minutes, greater actual temperatures were associated with less stroke and reoperation for bleeding. There were no significant differences among the predicted hypothermia levels, although a trend toward a higher rate of adverse events was noticed in the deep hypothermia group. Long-term survival was better in the moderate hypothermia group.

Patient-specific assessment of hemodynamics by computational fluid dynamics in patients with bicuspid aortopathy.
Hemodynamics related to eccentric blood flow may factor into the development of bicuspid aortic valve aortopathy. We investigated wall shear stress distribution by means of magnetic resonance imaging-based computational fluid dynamics in patients with a bicuspid aortic valve. ⋯ Computational fluid dynamics simulation is useful for precise evaluation of hemodynamics related to bicuspid aortic valve aortopathy. Such evaluation will advance our understanding of the disease pathophysiology and may facilitate molecular biological investigation.

Meta AnalysisSystematic review and meta-analysis of randomized controlled trials assessing safety and efficacy of posterior pericardial drainage in patients undergoing heart surgery.
To investigate the potential beneficial effects of posterior pericardial drainage in patients undergoing heart surgery. ⋯ Posterior pericardial drainage is safe and simple technique that significantly reduces not only the prevalence of early pericardial effusion and POAF but also late pericardial effusion and cardiac tamponade. These benefits, in turn, translate into improved survival after heart surgery.
