Background: There is limited evidence for the use of an intra-aortic balloon pump (IABP) in adult patients with a total cavopulmonary, or Fontan circulation.

Case Summary: A patient in his twenties with a Fontan circulation presented with sepsis, pneumonia, and pulmonary oedema. He was born with a hypoplastic left ventricle, atrioventricular septal defect, and hypoplastic aortic arch, and a total cavopulmonary circulation had been established within his first years of life.

Introduction: The complement system and neutrophil extracellular traps (NETs) might contribute to ischemia-reperfusion injury in ST-elevation myocardial infarction (STEMI). We aimed to estimate associations between complement activation and NETs in STEMI, and their prognostic value on clinical endpoints.

Methods: In this cohort study, 864 patients admitted for PCI during STEMI were included.

Objective: The role of neutrophil extracellular traps (NETs) in acute heart failure is unknown. We recently showed that interleukin 8, a putative NETs stimulator, was associated with myocardial recovery in acute heart failure complicating ST-elevation myocardial infarction (STEMI). In this exploratory post-hoc study, we aimed to investigate the role of NETs components in relation to myocardial function and interleukin 8 in STEMI patients with symptomatic acute heart failure.

Complement activation and neutrophil extracellular traps (NETs) have both been suggested to drive atherosclerotic plaque progression. Although experimental studies suggest interplay between these two innate immunity components, the relevance in patients with coronary artery disease (CAD) is unclear. The aim of this study was to assess associations between complement activation and NETs in patients with stable CAD and examine the role of complement activation on clinical outcome.

Neutrophil extracellular traps (NETs) have been implicated in atherothrombosis; however, their potential role as markers of risk is unclear. We investigated whether circulating NETs-related components associated with clinical outcome and hypercoagulability in ST-elevation myocardial infarction (STEMI). In this observational cohort study, STEMI patients admitted for PCI (n = 956) were followed for median 4.

Background: The relevance of neutrophil extracellular traps (NETs) in acute ST-elevation myocardial infarction (STEMI) is unclear. We explored the temporal profile of circulating NET markers and their associations to myocardial injury and function and to adverse clinical events in STEMI patients.

Methods And Results: In 259 patients, blood samples were drawn before and after PCI, on day 1, and after 4 months.

Background Neutrophil extracellular traps, comprising chromatin and granule proteins, have been implicated in atherothrombosis. Design and methods We investigated whether the circulating neutrophil extracellular traps markers, double-stranded DNA and myeloperoxidase-DNA were associated with clinical outcome and hypercoagulability in patients with stable coronary artery disease. Patients with angiographically verified stable coronary artery disease ( n = 1001) were included.

Objective: Clinical consultations with patients should be informed by the evidence-based and involve shared decision making (SDM). We aimed to determine the delivery of SDM by clinicians with patients referred for invasive treatment of cardiac electrical disease and to establish whether decisions made corresponded with patient and referring physician expectations.

Methods: Forty-nine outpatient consultations with two consultant cardiologists in one large tertiary centre were audio-recorded.
