Severe Pulmonary Bleeding after Assist Device Implantation: Incidence, Risk Factors and Prognostic Impact.

Background: Continuous flow left ventricular assist devices (CF-LVAD) improve survival in patients with advanced heart failure but confer risk of bleeding complications. Whereas pathophysiology and risk factors for many bleeding complications are well investigated, the literature lacks reports about pulmonary bleeding. Therefore, it was the aim of the present study to assess incidence, risk factors, and clinical relevance of pulmonary bleeding episodes after LVAD implantation.

(1) Background: Acute kidney injury (AKI) is a common but under-investigated complication in patients receiving extracorporeal membrane oxygenation (ECMO). We aimed to define the incidence and clinical course, as well as the predictors of AKI in adults receiving ECMO support. (2) Materials and Methods: This is a retrospective analysis of all patients undergoing veno-venous ECMO treatment in a tertiary care center between December 2008 and December 2017.

Prediction of Acute Kidney Injury by Cystatin C and [TIMP-2]*[IGFBP7] after Thoracic Aortic Surgery with Moderate Hypothermic Circulatory Arrest.

(1) Background: Acute kidney injury (AKI) is a common complication following thoracic aortic surgery (TAS), with moderate hypothermic circulatory arrest (MHCA). However, prediction of AKI with classical tools remains uncertain. Therefore, it was the aim of the present study to evaluate the role of new biomarkers in patients after MHCA.

Use of extracorporeal circulation (ECLS/ECMO) for cardiac and circulatory failure -A clinical practice Guideline Level 3.

Aims Worldwide applications of extracorporeal circulation for mechanical support in cardiac and circulatory failure, which are referred to as extracorporeal life support (ECLS) or veno-arterial extracorporeal membrane oxygenation (va-ECMO), have dramatically increased over the past decade. In spite of the expanding use and the immense medical as well as socio-economic impact of this therapeutic approach, there has been a lack of interdisciplinary recommendations considering the best available evidence for ECLS treatment. Methods and Results In a multiprofessional, interdisciplinary scientific effort of all scientific societies involved in the treatment of patients with acute cardiac and circulatory failure, the first evidence- and expert consensus-based guideline (level S3) on ECLS/ECMO therapy was developed in a structured approach under regulations of the AWMF (Association of the Scientific Medical Societies in Germany) and under use of GRADE (Grading of Recommendations Assessment, Development and Evaluation) criteria.

[Use of extracorporeal circulation (ECLS/ECMO) for cardiac and circulatory failure : Short version of the S3 guideline].

In Germany, a remarkable increase regarding the usage of extracorporeal membrane oxygenation (ECMO) and extracorporeal life support (ECLS) systems has been observed in recent years with approximately 3000 ECLS/ECMO implantations annually since 2015. Despite the widespread use of ECLS/ECMO, evidence-based recommendations or guidelines are still lacking regarding indications, contraindications, limitations and management of ECMO/ECLS patients. Therefore in 2015, the German Society of Thoracic and Cardiovascular Surgery (GSTCVS) registered the multidisciplinary S3 guideline "Use of extracorporeal circulation (ECLS/ECMO) for cardiac and circulatory failure" to develop evidence-based recommendations for ECMO/ECLS systems according to the requirements of the Association of the Scientific Medical Societies in Germany (AWMF).

[Training module extracorporeal life support (ECLS): consensus statement of the DIVI, DGTHG, DGfK, DGAI, DGIIN, DGF, GRC and DGK].

Mechanical circulatory support using extracorporeal life support systems (ECLS) has significantly increased in recent years. These critically ill patients pose special challenges to the multiprofessional treatment team and require comprehensive, interdisciplinary and interprofessional concepts. For this reason, to ensure the best possible patient care a standardized ECLS training module has been created at national specialist society level, taking emergency and intensive care management into account.

The German-Austrian S3 Guideline "Cardiogenic Shock Due to Myocardial Infarction: Diagnosis, Monitoring, and Treatment".

Despite advances in the treatment of acute myocardial infarction with subsequent mortality reduction, which are mainly caused by the early timing of revascularization, cardiogenic shock still remains the leading cause of death with mortality rates still approaching 40 to 50%. Cardiogenic shock is characterized by a multiorgan dysfunction syndrome, often complicated by a systemic inflammatory response syndrome that affects the outcome more than the reduction of the cardiac contractile function. However, both European and American guidelines on myocardial infarction focus on interventional or surgical aspects only.

[Recommendations for emergency management of patients with permanent mechanical circulatory support : Consensus statement of DGTHG, DIVI, DGIIN, DGAI, DGINA, DGfK and DGK].

The prevalence of patients living with long-term mechanical circulatory support (MCS) is rapidly increasing due to improved technology, improved survival, reduced adverse event profiles, greater reliability and mechanical durability, and limited numbers of organs available for donation. Patients with long-term MCS are very likely to require emergency medical support due to MCS-associated complications (e.g.

[Acute right heart failure on the intensive care unit : Pathophysiology, monitoring and management].

Right ventricular heart failure is a frequent and serious but often undetected and complex clinical challenge on the intensive care unit. The commonest causes include acute decompensation of pulmonary hypertension, pulmonary embolism, sepsis, acute respiratory distress, and cardiothoracic surgery. The gold standard of bedside diagnosis is a combination of clinical symptoms, biochemical markers (NT-proBNP) and echocardiography.

Prediction of acute kidney injury after left ventricular assist device implantation: Evaluation of clinical risk scores.

Acute kidney injury (AKI) is frequent in patients scheduled for implantation of a left ventricular assist device (LVAD) and associated with increased mortality. Although several risk models for the prediction of postoperative renal replacement therapy (RRT) have been developed for cardiothoracic patients, none of these scoring systems have been validated in LVAD patients. A retrospective, single center analysis of all patients undergoing LVAD implantation between September 2013 and July 2016 was performed.

Multiplex polymerase chain reaction to diagnose bloodstream infections in patients after cardiothoracic surgery.

Background: Sepsis and other infectious complications are major causes of mortality and morbidity in patients after cardiac surgery. Whereas conventional blood culture (BC) suffers from low sensitivity as well as a reporting delay of approximately 48-72 h, real-time multiplex polymerase chain reaction (PCR) based technologies like "SeptiFast" (SF) might offer a fast and reliable alternative for detection of bloodstream infections (BSI). The aim of this study was to compare the performance of SF with BC testing in patients suspected of having BSI after cardiac surgery.

The aspartate transaminase/alanine transaminase (DeRitis) ratio predicts mid-term mortality and renal and respiratory dysfunction after left ventricular assist device implantation.

Objectives: Preoperative liver dysfunction is a well-known risk factor for adverse events after major surgery. However, there is only little data regarding the precise role of the Model of End-Stage Liver Disease (MELD) score and the De Ritis ratio (DRR, alanine transaminase/aspartate aminotransferase) as a predictor for outcome after left ventricular assist device (LVAD) implantation.

Methods: A retrospective analysis of all patients undergoing LVAD implantation at our institution between January 2012 and August 2014 was performed.

Extracorporeal membrane oxygenation for acute respiratory distress syndrome in adults: an analysis of differences between survivors and non-survivors.

Objectives: Over the last decade, extracorporeal membrane oxygenation (ECMO) has become a promising option for patients with severe acute respiratory distress syndrome (ARDS). In this single-center observational cohort study, data from a patient group with severe ARDS treated with ECMO was analyzed.

Methods: Data from 46 patients [median age 54 years (18 to 72), male: 65.

Is universal antifungal prophylaxis mandatory in adults after lung transplantation? A review and meta-analysis of observational studies.

Background: Lung transplant (LTX) recipients are at high risk of invasive Aspergillus infections (IAI). However, no randomized-controlled trials (RCT) or international guidelines on antifungal prophylaxis (AFP) in the LTX population exist.

Methods: A meta-analysis was performed to determine whether AFP reduces the rate of IAI after LTX.

Early prediction of acute kidney injury after transapical and transaortic aortic valve implantation with urinary G1 cell cycle arrest biomarkers.

Background: Acute kidney injury (AKI) is a common complication following transcatheter aortic valve implantation (TAVI) leading to increased mortality and morbidity. Urinary G1 cell cycle arrest proteins TIMP-2 and IGFBP7 have recently been suggested as sensitive biomarkers for early detection of AKI in critically ill patients. However, the precise role of urinary TIMP-2 and IGFBP7 in patients undergoing TAVI is unknown.

Role of regional aortic wall properties in the pathogenesis of thoracic aortic dissection.

Objectives: The mechanisms of the location and extension of acute aortic dissection (AD) are only poorly understood. The aim of this study was to compare the cohesion of the non-coronary aortic sinus (NAS) and the ascending aortic wall (AA) using the Dissectometer - a new device for analyses of the mechanical properties of the aorta.

Design: The properties of the aortic wall were analyzed with the "Dissectometer" (parameters P7, P8 and P9) in adult patients undergoing aortic root (AR) replacement in two different segments: NAS and AA.
