Influence of minimal invasive extracorporeal circuits on dialysis dependent patients undergoing cardiac surgery.

Introduction: Cardiac surgery in patients on chronic renal dialysis is associated with significant morbidity and mortality. Minimally invasive extracorporeal circuits (MiECC) have shown a positive impact on patient outcome in different high-risk populations. This retrospective study compares the outcome of these high-risk patients undergoing heart surgery either with a MiECC or a conventional extracorporeal circulation (CECC).

Prehabilitation in older patients prior to elective cardiac procedures (PRECOVERY): study protocol of a multicenter randomized controlled trial.

Background: Previous studies have demonstrated the efficacy of rehabilitation after a cardiovascular procedure. Especially older and multimorbid patients benefit from rehabilitation after a cardiac procedure. Prehabilitation prior to cardiac procedures may also have positive effects on patients' pre- and postoperative outcomes.

Digital polymerase chain reaction to monitor platelet transfusions in cardiac surgery patients.

Background And Objectives: Corrected count increment (CCI) measurements monitor the effectiveness of platelet transfusions in haemato-oncology, but they usually fail in patients undergoing cardiac surgery. We investigated whether polymerase chain reaction (PCR) of mitochondrial single-nucleotide polymorphisms (SNPs) is able to monitor the survival of transfused platelets in these patients.

Materials And Methods: Leukocyte-free, platelet-rich plasma was prepared from patients' blood to measure platelet counts based on patient-/donor-specific SNPs by digital PCR after DNA extraction.
