Abstract

Post-procedural conduction disorders following transcatheter aortic valve replacement remain frequent, especially using the largest self-expandable device (Corevalve Evolut RTM, 34-mm, STHV-34, Medtronic, Minneapolis, Minnesota). Therefore, we assessed previously described, predictive factors of

Abstract

Protection against acute kidney injury (AKI) has been reported with the use of Impella during high-risk percutaneous coronary intervention (HR-PCI). As further validation of both these findings and their clinical applications is lacking, we analyzed the occurrence of AKI in patients from the

Abstract

In-hospital mortality in acute myocardial infarction-related cardiogenic shock (AMI-CS) remains high at ~40%. No prospective trials have been finished investigating the influence of mechanical support in AMI-CS. We compared observed to individually predicted mortality using CardShock-, Shock II

Abstract

Recently, Nagatomo et al. [(1)][1] reported on the predictive value of β1-adrenergic receptor autoantibodies (β1AAbs) for recovery from acute cardiac failure (HF). The investigators found a much lower prevalence of β1AAbs in HF than those in comparable studies [(2)][2]. Moreover

Abstract

Takotsubo Syndrome (TS) is an acute heart failure syndrome with considerable risk of shock, resuscitation and death. LVEF is strongly reduced and left ventricular end-diastolic-pressure (LVEDP) is increased in almost all cases. Catecholamines are considered to play a causal role for the disease and

Abstract

In patients with cardiogenic shock, pneumonia due to pulmonary congestion and subsequent septic shock is associated with high mortality. In this setting, reduced cardiac index, elevated filling pressure, and acute exacerbation of mitral regurgitation are the main driving factors underlying pulmonary
