The Impact of Fluid Balance on the Detection, Classification and Outcome of Acute Kidney Injury After Cardiac Surgery.
To assess whether or not a positive fluid balance masks acute kidney injury (AKI) and is associated with adverse outcomes after cardiac surgery. ⋯ Patients with AKI diagnosed after correction for the effect of a positive fluid balance on serum creatinine concentration have more adverse outcomes than patients without AKI by conventional criteria, but fewer than patients with AKI by conventional criteria.

Observational StudyNeurologic Derangement and Regional Cerebral Oxygen Desaturation Associated With Patency of the Circle of Willis During Carotid Endarterectomy.
To explore the relationship between the maximal fractional decrease of regional cerebral oxygen saturation (rSO2) in neurologic derangement and the patency of the circle of Willis and contralateral carotid artery stenosis. ⋯ The rSO2 can be used to predict shunt insertion, regardless of the patency of the circle of Willis. The probability of shunt insertion increased with increasing degree of contralateral carotid artery stenosis in the absence of anterior circulation in the circle of Willis.

Observational StudyPredicting New-Onset Postoperative Atrial Fibrillation in Cardiac Surgery Patients.
To derive a simple clinical prediction rule identifying patients at high risk of developing new-onset postoperative atrial fibrillation (POAF) after cardiac surgery. ⋯ This study proposed a simple predictive score incorporating three risk variables to identify cardiac surgical patients at high risk of developing new-onset POAF. Preventive treatment should target patients ≥ 65 years with left atrial dilatation and mitral valve disease.

Acute Effects of Pacing at Different Ventricular Sites on Left Ventricular Rotational Mechanics in a Porcine Model.
The purpose of this study was to examine the acute effects of pacing at different ventricular sites on hemodynamics and left ventricular (LV) rotational mechanics using speckle-tracking echocardiography (STE) in a porcine model. ⋯ The present data showed that the LV twist/untwist and cardiac systolic and diastolic function were least affected by RVOT pacing. This finding may be explained by the proximity of this location to the native ventricular conduction system.
