Targeted Left Ventricular Lead Placement, Comparison of Active Fixation Bipolar and Passive Quadripolar...
Heart FailureA prospective, randomized and patient-blinded trial comparing an active fixation left ventricular lead with quadripolar passive left ventricular leads. The leads were compared in order to identify differences in the electrical performance, the ability to achieve a stable proximal position in a coronary vein located concordant to target segment and clinical outcome. The patients were followed up for 12 months.

The SWISSHEART Failure Network (SHFN)
Heart Failure AcuteAcute Myocardial InfarctionA retrospective cohort study will be conducted on patients who were hospitalized at the University Hospital Basel (USB), University Hospital Bern (Inselspital), University Hospital Geneva (HUG) and the University Hospital Zurich (USZ) with the diagnosis of AMI and/or AHF. Baseline data will be collected in the hospital during treatment will be complemented by a short outcome evaluation.

CT Guided WiSE-CRT
Heart FailureThis feasibility study will use CT scanning to identify the optimal location for placement of the WiSE-CRT system.

Patient-reported Outcomes in Vericiguat-treated Patients With HFpEF
Chronic Heart Failure With Preserved Ejection FractionThe primary hypothesis in this trial is that the treatment with vericiguat 10 mg or 15 mg in patients with HFpEF improves the KCCQ PLS (Kansas City Cardiomyopathy Questionnaire Physical limitation score) compared to placebo after 24 weeks of treatment.

CardioMEMS HF System OUS Post Market Study
Heart FailureLeft-Sided Heart Failure1 moreThe purpose of this Post Market Study (PMS) is to evaluate the use of the CardioMEMS HF System in patients with Class III Heart Failure in a commercial setting.

Evaluation of the Safety and Efficacy of the 2-lead OPTIMIZER® Smart System
Heart FailureCongestive Heart Failure2 moreThis is a multicenter, prospective, single-arm study of the Optimizer Smart System with 2-leads

Ventilatory Support Associated With Exercise in Heart Failure
Heart FailureDue to the symptoms of heart failure (HF), as dyspnea and fatigue, patients have a reduced functional capacity, evidenced during usual daily activities and exercises. The Cardiac Rehabilitation with emphasis on resistance and aerobic exercises performed in the same session (concurrent training), can be added to pharmacological treatment as improvement strategy in functional capacity and quality of life.

The Application of Negative Atrioventricular Hysteresis in Cardiac Resynchronization Therapy
Heart FailureThe purpose of this study is to evaluate the application of Negative Atrioventricular Hysteresis (NAVH) to improve electrical synchrony in Cardiac Resynchronization Therapy (CRT) patients.

Changes in Myocardial Iron After Iron Administration
Heart FailureIron-deficiencyRecent studies have shown that treatment with intravenous iron in patients with iron deficiency (ID) and heart failure with reduced ejection fraction (HFrEF) improves symptomatology, functional capacity, quality of life, and decreases hospitalizations regardless of anemia. In addition, a decrease in myocardial iron content has been observed in patients with chronic HFrEF. This preliminary evidence has led to postulate that myocardial iron deficiency could play a direct role in the pathogenesis and progression of the disease. The investigators hypothesize that the repletion of myocardial iron would explain part of the benefit of this treatment. Thus, the investigators postulate that cardiac magnetic resonance (CMR) (T2* and T1-mapping sequences) will be sensible enough to detect changes in myocardial iron content as a result of intravenous iron administration, and that such changes will correlate with simultaneous changes in parameters of heart failure severity. In this double-blind 1:1 randomized study controlled by placebo the investigators aim to determine the changes in myocardial iron content after treatment with intravenous ferric carboxymaltose (FCM) by CMR at 7 and 30 days in patients with stable HFrEF and ID.

ECG Belt for CRT Response
Heart FailureThe purpose of this clinical study is to compare ECG Belt Research System managed cardiac resynchronization therapy (CRT) patients and a control CRT group with respect to left ventricular (LV) remodeling.
