Aims: Heart failure-related cardiogenic shock (HF-CS) accounts for about half of CS cases, with a paucity of data regarding the role of kidney injury in this subset. This study aims to evaluate patient characteristics and outcome associated with renal function in patients with HF-CS.
Methods And Results: In this multicentre, international, retrospective study, patients with HF-CS from 16 tertiary care centres in five countries were enrolled between 2010 and 2021.
Aims: This study aimed to investigate incidence and predictors of weaning failure and in-hospital death after successful weaning from veno-arterial extracorporeal membrane oxygenation (VA-ECMO) in patients with cardiogenic shock (CS).
Methods And Results: Overall, 685 patients with CS treated with VA-ECMO from 23 tertiary care centres in 7 countries were analysed (median age 57 [interquartile range 49-66] years, 542 [79.1%] male, median lactate 7.
Article Synopsis
- * Women with HF-CS tend to be older, have fewer prior heart issues, and lower rates of severe heart dysfunction compared to men, yet both genders received similar treatments.
- * Despite ranking equally in treatment use, the 30-day mortality rates were also comparable between sexes (around 53% for women and 51% for men), suggesting the need for further investigation into sex-specific treatment strategies.
Article Synopsis
- Researchers studied the use of mechanical circulatory support (MCS) in patients with non-ischaemic cardiogenic shock (CS), focusing on how left ventricular ejection fraction (LVEF) could influence patient outcomes.
- An analysis of 807 patients showed that while lower LVEF was linked to more severe shock, it didn't correlate with overall 30-day mortality risk; however, MCS appeared to reduce mortality in those with severely reduced LVEF (≤20%).
- The study suggests that incorporating LVEF into decision-making for MCS in non-ischaemic CS patients could improve patient outcomes by optimizing the benefit-risk ratio.
Article Synopsis
- - The study aimed to compare clinical characteristics and 30-day mortality rates between patients with de novo heart failure-related cardiogenic shock (HF-CS) and those with acute-on-chronic HF-CS, finding significant differences in outcomes.
- - An analysis of 1,030 patients revealed that while traditional markers of severity were similar, acute-on-chronic HF-CS was linked to higher mortality rates (55.9% vs. 45.5%) and greater severity of shock.
- - The results suggest that the chronicity of heart failure significantly influences the severity of cardiogenic shock, underlining the need to consider this factor in future clinical trials.
Article Synopsis
- VA-ECMO therapy helps patients with cardiogenic shock by restoring circulation but can lead to various complications affecting survival and neurological outcomes.
- A study analyzed data from 501 patients across 16 centers, revealing that over half experienced complications, especially women, with 40% mortality within 30 days.
- The findings indicate a need for better identification of patients at risk for complications to improve treatment strategies, as most adverse events correlate with worse prognosis.
Background: predicting the 1-year survival of patients undergoing transcatheter aortic valve implantation (TAVI) is indispensable for managing safe early discharge strategies and resource optimization.
Methods: Routinely acquired data (134 variables) were used from 629 patients, who underwent transfemoral TAVI from 2012 up to 2018. Support vector machines, neuronal networks, random forests, nearest neighbour and Bayes models were used with new, previously unseen patients to predict 1-year mortality in TAVI patients.
Aims: Despite its high incidence and mortality risk, there is no evidence-based treatment for non-ischaemic cardiogenic shock (CS). The aim of this study was to evaluate the use of mechanical circulatory support (MCS) for non-ischaemic CS treatment.
Methods And Results: In this multicentre, international, retrospective study, data from 890 patients with non-ischaemic CS, defined as CS due to severe de-novo or acute-on-chronic heart failure with no need for urgent revascularization, treated with or without active MCS, were collected.
Background: It is currently unclear if active left ventricular (LV) unloading should be used as a primary treatment strategy or as a bailout in patients with cardiogenic shock (CS) treated with venoarterial extracorporeal membrane oxygenation (VA-ECMO).
Objectives: This study sought to evaluate the association between timing of active LV unloading and implantation of VA-ECMO with outcomes of patients with CS.
Methods: Data from 421 patients with CS treated with VA-ECMO and active LV unloading at 18 tertiary care centers in 4 countries were analyzed.
Objectives: The aim of this study was to analyse the outcome of patients between 50 and 69 years of age undergoing biological or mechanical aortic valve replacement.
Methods: Data were collected from the German Aortic Valve Registry. Data were analysed regarding baseline characteristics and outcome parameters such as 5-year survival, stroke and reintervention.
The COVID-19 pandemic is placing a heavy burden on healthcare systems worldwide with the risk that acute cardiovascular diseases are treated too late. The present study aims to analyze patients with acute coronary syndrome in the current pandemic. A total of 966 patients (2019 = 463, 2020 = 503) can be evaluated.

Meanwhile, percutaneous closure systems became a well-established alternative. The aim of this study was to compare the clinical outcome between the two approaches.

Background: Venoarterial extracorporeal membrane oxygenation (VA-ECMO) is increasingly used to treat cardiogenic shock. However, VA-ECMO might hamper myocardial recovery. The Impella unloads the left ventricle.

An acute myocardial injury is defined as a significant increase of cardiac troponins (cTn). In patients with an additional myocardial ischemia, which is defined by certain clinical, electrocardiographic, imaging and angiographic criteria, the diagnosis of acute MI can be made.

Ann Thorac Surg
November 2020
The HAART 300 (BioStable Science and Engineering, Austin, TX) is a rigid, elliptical device introduced to facilitate aortic valve repair providing annular stabilization in the setting of aortic regurgitation. Percutaneous strategies have been described for patients with dysfunctional biological prostheses or recurrence insufficiency after mitral ring annuloplasty. This report shows the feasibility of aortic valve-in-ring transcatheter aortic valve replacement (TAVR).

Methods: Data of all patients treated with SAVR (n = 1068) and TAVR (n = 816) due to severe aortic valve stenosis was collected at our center from 2010 to 2017. Preprocedural and postprocedural values were collected from electronic patient records.
Background: Percutaneous mechanical circulatory support devices are increasingly used in acute myocardial infarction complicated by cardiogenic shock (AMI-CS), despite limited evidence for their effectiveness. The aim of this study was to evaluate outcomes associated with use of the Impella device compared with intra-aortic balloon pump (IABP) and medical treatment in patients with AMI-CS.
Methods: Data of patients with AMI-CS treated with the Impella device at European tertiary care hospitals were collected retrospectively.
Background: Frailty is a geriatric syndrome that can influence mortality and functional recovery after treatment of severe aortic stenosis (AS). The integration of standardized geriatric assessment (GA) in clinical practice is limited by a lack of consensus on how to measure it.
Objectives: This study aims to compare the incremental predictive value of different frailty scales to predict the outcomes following surgical aortic valve replacement, transcatheter aortic valve implantation, and conservative treatment of severe AS.
Incidence and outcomes of emergent cardiac surgery during transfemoral transcatheter aortic valve implantation (TAVI): insights from the European Registry on Emergent Cardiac Surgery during TAVI (EuRECS-TAVI).

Aims: Life-threatening complications occur during transcatheter aortic valve implantation (TAVI) which can require emergent cardiac surgery (ECS). Risks and outcomes of patients needing ECS during or immediately after TAVI are still unclear.
Methods And Results: Incidence, risk factors, management, and outcomes of patients requiring ECS during transfemoral (TF)-TAVI were analysed from a contemporary real-world multicentre registry.
