AVJ Ablation Followed by Resynchronization Therapy in Patients With CHF and AF
Atrial FibrillationCongestive Heart FailureThe purpose of the study is to determine if the combination of AVJ ablation followed by BiV pacing significantly improves functional status and exercise capacity compared to pharmacologic rate control in patients with chronic AF and depressed ejection fraction, regardless of rate or QRS duration.
Study to Evaluate the Effect of SLV320 in Addition to Chronic Furosemide Treatment on Renal Function...
Congestive Heart FailureThis is a randomized, double-blind, placebo-controlled, multi-center, sequential cohort study in subjects with congestive heart failure (CHF) and impaired renal function who are on stable furosemide treatment (³ 40 mg daily). A total of 50 subjects will be randomized to each increasing dose level of SLV320 or placebo in a sequential fashion.
Cardiac Metabolic Remodeling After Pulmonary Vasodilator Therapy in Pulmonary Arterial Hypertension:...
Pulmonary Arterial HypertensionRight-Sided Heart FailurePulmonary arterial hypertension(PAH) is associated with the development of right heart failure. In the setting of heart failure, the heart shifts to increasing dependence on glucose metabolism. In this study, the investigators will perform cardiac positron emission tomography/magnetic resonance imaging (PET/MRI) scans to measure glucose metabolism in the heart before and after initiation of pulmonary vasodilator therapy for pulmonary arterial hypertension.

Pronostic Value of Endothelial Dysfunction in Heart Failure
Heart DecompensationCardiac FailureThe main objective is to evaluate the pronostic value of endothelial dysfonction in acute heart failure on a combined criteria associating cardiovascular mortality, nex hospitalisation for decompensated heart failure, cardiac graft or ventricular assistance 2 month and 1 year before acute heart failure.
Use of POC Pocket Ultrasound in the Estimation of Left and Right Atrial Pressures
Heart FailureAcute Decompensated Heart FailureThis study will assess the reliability of POC ultrasound in estimating right and left atrium pressures in patients with acute decompensated heart failure. This study will compare hemodynamic measurements obtained from pulmonary artery catheters with those estimated from POC ultrasound using inferior vena cava (IVC) measurements and the presence of atrial septal bulge.
Cardiac Perfusion and Metabolism With [11C] Acetate PET/CT is Associated With Hematopoietic System...
Acute Decompensated Heart FailureThe purpose of this sub-study is to use positron emission tomography and computed tomography imaging (PET/CT) with an investigational drug called [11C] acetate to see if inflammation in patients with acute decompensated heart failure (ADHF) can cause changes in blood flow and oxygen use in the heart. This study may help physicians better understand how to treat patients diagnosed with ADHF in the future.
Atrial Fibrillation Associated With Heart Failure Treated by BIOTRONIK's CRT-DX System
Heart FailureAtrial Fibrillation1 moreThe purpose of the BIO-AffectDX Study is to prospectively evaluate improvement from baseline in heart failure subjects with atrial fibrillation (AF) implanted with a two-lead CRT-DX system, with emphasis on a comparison of patient outcomes between AF subtypes.
Heart Failure and Risk of Re-Admissions Determined by Abnormal REVEAL Parameters
Heart FailureThe purpose of the Heart Failure and Risk of re-Admissions Determined by Abnormal REVEAL Parameters (HF RADAR) study is to evaluate the ability of cardiac rhythm (Cardiac Compass) data to predict future cardiac events in heart failure (HF) patients recently discharged after a hospitalization for heart failure who have or plan to have a implanted loop recorder (ILR), specifically, the Reveal XT device. The study will enroll 40 HF patients (with LV function ≥ 40%) admitted to an acute care facility (observation status or hospital stay) for heart failure who either have a Reveal XT device in place or plan to have the ILR device inserted for clinical indication within 14 days of discharge from the hospitalization. HF patients will be followed for 6 months. Device date will be captured during normal clinic visits and at 6 months.
