Multicenter Study Comparative StudyMid-term mechanical circulatory support: comparison of single-centre data with the EUROMACS registry.
Mechanical circulatory support (MCS) is an established therapy for end-stage heart failure. The EUROMACS registry was created to promote research in patients with MCS and became a committee of the European Association for Cardio-Thoracic Surgery (EACTS) in 2014. Since 1 January 2011, increasing numbers of European centres implanting durable MCS have reported their patient data to EUROMACS. The aim of this study is to compare, as an example of internal quality control, data from a single centre (Bern) with those from the EUROMACS database with respect to mortality rates and preoperative patient characteristics and to describe complications in Bern. ⋯ MCS is a valuable therapeutic option with excellent survival rates; nevertheless, it is associated with clinically significant complication rates. International registries are important tools that allow, as an example, internal quality control of mortality, complication and morbidity rates from a single centre compared with the EUROMACS database.

ReviewTechniques and standards in intraoperative graft verification by transit time flow measurement after coronary artery bypass graft surgery: a critical review.
Transit time flow measurement (TTFM) is a quality control tool for intraoperative graft evaluation in coronary artery bypass graft (CABG) surgery. A critical review of the literature available using TTFM in CABG surgery is the focus of this article. The main objectives will be to detail precise parameters for flow evaluation, to show limitations of TTFM and to prove its predictive impact on postoperative graft failure rate. ⋯ Influence of quantity (vessel territory distribution) and quality (myocardial scar) of the graft perfusion area, on TTFM and FU outcome, was not included by anyone and should be part of future research. TTFM is probably not the tool of choice to detect progressive late graft failure of SVG. Peroperative TTFM values should be correlated with one type of conduit, differentiating between early and late graft failure (by applying a uniform, appropriated definition), to precise and confirm threshold values.
