Background: In-hospital mortality in acute myocardial infarction-related cardiogenic shock (AMI-CS) remains high. The only adequately powered randomized trial showed no benefit of routine us of the intra-aortic balloon pump in AMI-CS. We compared individually predicted mortality using CardShock- and IABP-Shock II-scores in AMI-CS patients treated with an Impella microaxial pump, who met the IABP-Shock II-trials inclusion/exclusion criteria, to observed mortality on circulatory support in order t...

BACKGROUND: Percutaneous coronary intervention (PCI) represents an important alternative to coronary bypass surgery for the treatment of patients with complex coronary artery disease and high perioperative risk. Protected percutaneous coronary intervention applies temporary percutaneous ventricular assist devices to mitigate potential hemodynamic compromise in high-risk patients. The Impella system is currently the most commonly used device for protected percutaneous coronary intervention and sh...

OBJECTIVES: The purpose of this study was to investigate the impact of periprocedural troponin levels on clinical outcome following the MitraClip procedure. BACKGROUND: Cardiac troponin is known to be a predictive biomarker for various clinical outcomes; however, data about its predictive value in patients undergoing transcatheter mitral valve repair are limited. METHODS: Consecutive patients undergoing the MitraClip procedure were enrolled. Serum cardiac troponin I concentrations were measured ...

BACKGROUND: Transcatheter aortic valve replacement (TAVR) is an alternative treatment option to surgical aortic valve replacement (SAVR) in selected high-risk patients. In this study, we aimed to evaluate the prognostic value of right ventricular (RV) functional imaging to predict clinical response to TAVR and SAVR. METHODS: One hundred and ten patients with symptomatic severe aortic valve stenosis (AVS) undergoing successful TAVR and 32 controls undergoing SAVR were prospectively enrolled. Six ...

AIMS: We sought to investigate the relevance of myocardial fibrosis, assessed by mid-wall fibrosis risk (MFR) score, with respect to left ventricular (LV) reverse remodelling following transcatheter aortic valve replacement (TAVR). METHODS AND RESULTS: Between January 2010 and March 2015, we enrolled 207 patients in whom baseline MFR, which includes age, sex, high-sensitivity cardiac troponin I, presence of strain pattern on electrocardiography, and peak aortic valve velocity, as well as one-yea...

BACKGROUND: In the continuity equation, assumption of a round-shaped left ventricular outflow tract (LVOT) leads to underestimation of the true aortic valve area in two-dimensional echocardiography. The current study evaluated whether inclusion of the LVOT area, as measured by computed tomography (CT), reclassifies the degree of aortic stenosis (AS) and assessed the impact on patient outcome after transcatheter aortic valve replacement (TAVR). METHODS AND RESULTS: Four hundred and twenty-two pat...

Abstract Aims Although the bacterial virulent factor of cytotoxin-associated gene-A (CagA)-seropositivity and the host genetic factors of interleukin (IL)-1 polymorphisms have been suggested to influence Helicobacter pylori (HP) -related diseases, the underlying mechanisms of the association between HP infection and acute coronary syndrome (ACS) remain unknown. Methods and results Among 341 consecutive ACS patients, the clinical outcomes after ACS included composite cardiovascular events within ...

The benefit of TAVI in cancer patients is currently unclear. The purpose of this study is to investigate prognostic impact of cancer status (active cancer or previous cancer) in severe aortic stenosis (AS) patients undergoing transcatheter aortic valve implantation (TAVI). Consecutive TAVI patients in the Heart Center Bonn were enrolled and we stratified the patients into three groups: current cancer (active cancer), non-current cancer (previous cancer), or no cancer. The primary outcome was all...
