Randomized Controlled Trial Multicenter StudyLow preoperative hepcidin concentration as a risk factor for mortality after cardiac surgery: a pilot study.
Hepcidin regulates iron absorption and recycling and is central to host defense, protection from reactive iron species, and a biomarker of iron-related pathophysiology. We assessed the value of hepcidin measured preoperatively for the prediction of in-hospital mortality and renal outcomes. ⋯ Low preoperative hepcidin concentration might be a risk factor for in-hospital mortality. Findings should be validated in larger patient cohorts with a greater number of events.

Predictors of in-hospital complications after pericardiectomy: a nationwide outcomes study.
Advances in medical care had caused a paradigm shift in the indications for pericardiectomy. We evaluated the current predictors of in-hospital complications for pericardiectomy. ⋯ Morbidity remains high for pericardiectomy. In addition to age, gender, and comorbidities, attention should be given to etiology during surgical planning or referral. This significantly influences the requirement for cardiopulmonary bypass, chances of bleeding complications, and transfusion requirements.

Randomized Controlled Trial Multicenter StudySuperior cavopulmonary anastomosis timing and outcomes in infants with single ventricle.
We sought to identify factors associated with the timing and surgical outcomes of the superior cavopulmonary anastomosis. ⋯ Greater case complexity and more frequent interstage adverse events are associated with an earlier age at superior cavopulmonary anastomosis. Significant variation in age at superior cavopulmonary anastomosis among centers, independent of subject factors, highlights a lack of consensus regarding the optimal timing. Factors associated with length of stay could offer insights for improving presuperior cavopulmonary anastomosis care and surgical outcome.

Multicenter StudyFour-dimensional, flow-sensitive magnetic resonance imaging of blood flow patterns in thoracic aortic dissections.
The purpose of this study was to evaluate alterations in flow patterns in thoracic aortic dissections using 4-dimensional, flow-sensitive magnetic resonance imaging. ⋯ Four-dimensional, flow-sensitive magnetic resonance imaging at 3.0T provided qualitative and quantitative information on alterations of aortic flow in patients with thoracic aortic dissection. Future application of this magnetic resonance flow methodology may help provide insights into the pathophysiology and effects of flow alterations and establish prognostic indicators for the development of complications or aneurysm growth in patients with aortic dissection.
