Background The aim of the study was to assess the value of post-operative cardiac troponin T-levels, measured with a new highly sensitive assay (hs-cTnT), as a suitable parameter to predict patients' outcome after cardiac surgery. With the introduction of the new hs-cTnT assay the correlation between measured levels and the post-operative patient's outcome remains to be evaluated. Methods Patients undergoing coronary artery bypass grafting (n = 213) were included. ⋯ Upon discriminant analysis the application of hs-cTnT almost doubled the sensitivity of the outcome prediction. Conclusions The new hs-cTnT assay is a useful diagnostic tool that may significantly enhance the prediction of adverse events after CABG. In our study a hs-cTnT-value >1,476.8 pg/ml proved to be a reliable marker for ongoing post-operative complications.

Objective The aim of this study was to evaluate the incidence of venous stenosis and occlusion (VSO) in patients referred for transvenous lead extraction (TLE) with regard to the indications for this treatment and to analyse the influence of VSO on efficacy, complications and technical challenges of TLE procedures. Methods The material consists of 133 consecutive TLE procedure records. The contrast venography examination of the ipsilateral access vein was performed prior to the operation. ⋯ There is no association between indication for TLE (infected or noninfected lead extraction) and the incidence of VSO. Diabetes proved to have a protective effect on venous patency in the previously mentioned group. VSO does not influence the effectiveness, safety, and the use of additional tools during TLE procedures.
