Randomized Controlled Trial Comparative StudyNormothermic cardiopulmonary bypass increases cerebral tissue oxygenation during combined valve surgery: a single-centre, randomized trial.
In cardiac surgery, the choice of temperature regimen during cardiopulmonary bypass (CPB) remains a subject of debate. Hypothermia reduces tissue metabolic demands, but may impair the autoregulation of cerebral blood flow and contribute to neurological morbidity. The aim of this study was to evaluate the effect of two different temperature regimens during CPB on the systemic oxygen transport and the cerebral oxygenation during surgical correction of acquired heart diseases. ⋯ During combined valve surgery, normothermic CPB provides lower central venous oxygen saturation, but increases cerebral tissue oxygenation when compared with the hypothermic regimen.

Multicenter Study Comparative StudyThe impact of transcatheter aortic valve implantation on patients' profiles and outcomes of aortic valve surgery programmes: a multi-institutional appraisal.
The aim of this retrospective multicenter study was to assess how the development of transcatheter aortic valve implantation (TAVI) influenced the characteristics and outcomes of patients undergoing aortic valve procedures. ⋯ This analysis shows that the development of TAVI has caused an increase in the preoperative risk profile of patients scheduled for aortic valve procedures (SAVR or TAVI) without increasing hospital mortality.

Comparative StudyPrognostic value of nutritional screening tools for patients scheduled for cardiac surgery.
The aim of this study was to assess the prognostic value of different nutritional screening tools in patients undergoing cardiopulmonary bypass, with regard to adverse clinical outcome. ⋯ MUST and MNA both have independent predictive values with regard to postoperative complications. Taking into account simplicity, MUST is preferable for the cardiac surgical population.

Simplified model for end-stage liver disease score predicts mortality for tricuspid valve surgery.
The model for end-stage liver disease score (MELD = 3.8*LN[total bilirubin] + 9.6*LN[creatinine] + 11.2*[PT-INR] + 6.4) predicts mortality for tricuspid valve surgery. However, the MELD is problematic in patients undergoing warfarin therapy, as warfarin affects the international normalized ratio (INR). This study aimed to determine whether a simplified MELD score that does not require the INR for calculation could predict mortality for patients undergoing tricuspid valve surgery. Simplified MELD score = 3.8*LN[total bilirubin] + 9.6*LN[creatinine] + 6.4. ⋯ The simplified MELD score predicts mortality in patients undergoing tricuspid valve surgery. This model requires only total bilirubin and creatinine and is therefore applicable in patients undergoing warfarin therapy.
