Comparative StudyDoes preoperative B-type natriuretic peptide better predict adverse outcome and prolonged length of stay than the standard European System for Cardiac Operative Risk Evaluation after cardiac surgery?
Although B-type natriuretic peptide (BNP) strongly predicts cardiac morbidity and mortality, the European System for Cardiac Operative Risk Evaluation (EuroSCORE) has a modest predictive value to identify a composite operative risk after cardiac surgery. The authors tested the hypothesis that a single preoperative BNP measurement would be superior to standard EuroSCORE in predicting composite adverse outcomes after cardiac surgery. ⋯ Preoperative BNP measurement is a strong, independent, and more accurate predictor of adverse outcome than EuroSCORE in patients undergoing cardiac surgery. BNP could be considered as a simple and objective tool for the detection of high-risk patients after cardiac surgery.

Comparative StudyEstimating the volume of chronic pleural effusions using transesophageal echocardiography.
To develop a simple method of quantifying the volume of chronic pleural effusions caused by heart failure using transesophageal echocardiography measurement of the maximum cross-sectional area of the pleural effusion. ⋯ This study showed a simple way of quantifying the volume of chronic pleural effusions from heart failure in patients undergoing cardiac surgery, with potential for clinical applications.

Comparative StudyPropofol inhibits desflurane-induced preconditioning in rabbits.
The authors tested the hypothesis that ischemic and desflurane-induced preconditioning are blocked by propofol. ⋯ Desflurane-induced preconditioning markedly reduced infarct size and was blocked by propofol, whereas ischemic preconditioning was not blocked by propofol. The results suggest an important interference between propofol and anesthetic-induced preconditioning and might explain some contradictory findings in studies in humans.

Comparative StudyIntraoperative assessment of mitral valve area after mitral valve repair: comparison of different methods.
In the present study, 3 different methods to measure the mitral valve area (MVA) after mitral valve repair (MVRep) were studied. Data obtained immediately after repair were compared with postoperative data. The objective was to determine the feasibility and correlation between intraoperative and postoperative MVA data. ⋯ The MVA recorded immediately after valve repair, using PHT, correlated and agreed with MVA data obtained in the postoperative period. These results contrast with previously published data and could highlight the impact of hemodynamic function during the assessment of MVA.
