BACKGROUND: The implantation of rotary blood pumps as ventricular assist devices (VADs) has become a viable therapy for quite a number of patients with end-stage heart failure. However, these rotary blood pumps cause adverse events that are related to blood trauma. It is currently believed that turbulence in the pump flow plays a significant role. But turbulence has not been measured to date because there is no optical access to the flow space in rotary blood pumps because of their opaque casings...

BACKGROUND: Heart failure is a major cause of mortality and morbidity, particularly among patients with advanced disease and no access to cardiac transplantation. LVAD implantation is not only a bridge-to-transplantation option for patients awaiting a heart donor, but is often used as bridge-to-destination therapy in patients unsuited for transplantation for various reasons. LVAD infection is considered the second-most common cause of death in patients who survive the initial 6 months on LVAD support...

INTRODUCTION: The wearable cardioverter defibrillator (WCD) may allow stabilization until reassessment for an implantable cardioverter defibrillator (ICD) among high-risk HF patients. However, there are limited data on the WCD benefit in the acute decompensated HF setting. METHODS AND RESULTS: The Study of the Wearable Cardioverter Defibrillator in Advanced Heart-Failure Patients (SWIFT) was a prospective clinical trial carried out at two medical centers. Patients hospitalized with advanced HF symptoms and reduced left ventricular ejection function (LVEF) were enrolled and prescribed a WCD prior to discharge for a total of 3 months...

BACKGROUND: Based on a reduction in morbidity and mortality, cardiac resynchronisation therapy (CRT) has evolved as a standard therapy for patients with advanced heart failure. OBJECTIVE: To provide insight into patient demographics, safety, echocardiographic remodelling and long-term follow-up of patients treated with CRT in a "real-world" setting at a Swiss tertiary care centre. METHODS: Patients implanted with a CRT device at the University Heart Centre Zurich between 2000 and 2015 were consecutively enrolled...

Heart failure has mortality rates that parallel those of breast cancer. Current management strategies include neurohormonal blockade, rate control measures, natriuretic peptide preservation, implantation of mechanical assist devices, and heart transplantation. Despite these strategies, however, the failing myocardium remains energy depleted. New strategies to promote metabolic recovery are being developed to potentially augment current treatment guidelines. For example, an unexpected finding of our own studies showed that mechanical unloading with assist devices in advanced-stage heart failure restored metabolic flux...

OBJECTIVES: The purpose of this study was to investigate the differential impact of the 2 most commonly available left ventricular assist device (LVAD) types on the right (RV) and left (LV) ventricles using 3-dimensional (3D) echocardiography-based analysis of ventricular morphology. BACKGROUND: LVADs have emerged as common therapy for advanced heart failure. Recent data suggest that the heart responds differently to speed settings in the 2 main devices available (HeartMate II [HMII], St Jude Medical, Pleasanton, California, and HVAD, HeartWare International, Framingham, Massachusetts)...

Incident heart failure and the burden of hospitalization may be demonstrating a decline. However, as the population ages, the prevalence of heart failure continues to increase. Mortality among heart failure patients is increasingly due to non-cardiovascular causes. Current evidence-based therapy for heart failure has improved heart failure related mortality. Current efforts should be directed toward optimizing evidence based medical and device therapy, reducing morbidity, and increasing quality of life with heart failure...

BACKGROUND: Left ventricular assist devices (LVADs) have been used as an effective therapeutic option in patients with advanced heart failure, either as a bridge to transplantation, as destination therapy, or in some patients, as a bridge to recovery. OBJECTIVES: This study evaluated whether patients undergoing an LVAD bridge-to-recovery protocol can achieve cardiac and physical functional capacities equivalent to those of healthy controls. METHODS: Fifty-eight male patients-18 implanted with a continuous-flow LVAD, 16 patients with LVAD explanted (recovered patients), and 24 heart transplant candidates (HTx)-and 97 healthy controls performed a maximal graded cardiopulmonary exercise test with continuous measurements of respiratory gas exchange and noninvasive (rebreathing) hemodynamic data...

This case describes some of the commonly overlooked device-related issues in patients who have reportedly failed to respond to cardiac resynchronization therapy (CRT). The case demonstrates voltage-dependent right ventricular capture instead of right atrial capture by a subtly malpositioned right atrial lead. CRT therapy failed to improve symptoms of heart failure and the diagnosis of "CRT nonresponder" was made. With a detailed fact-finding approach, the mechanism behind this nonresponse was identified, and the outcome of CRT was significantly improved with rectification of the problems...

Venoarterial extracorporeal membrane oxygenation (ECMO) can provide temporary cardiopulmonary support for patients in hemodynamic extremis or refractory heart failure until more durable therapies-such as cardiac transplantation or a left ventricular assist device-can be safely implemented. Conventional ECMO cannulation strategies commonly employ the femoral artery and vein, constraining the patients to the supine position for the duration of ECMO support. We have recently adopted a modified cannulation approach to promote patient mobility, rehabilitation, and faster recovery and to mitigate complications associated with femoral arterial cannulation, such as limb ischemia and compartment syndrome...

The L2ANDS2 score was previously found to be able to assess the probability of left ventricular (LV) remodeling. We sought to evaluate this score in terms of clinical outcomes: 275 patients with heart failure, from 2 centers, implanted with a cardiac resynchronization therapy (CRT) device were followed at least 2 years after implantation. Baseline clinical, electrocardiographic, and echocardiographic characteristics including left bundle branch block, age >70 years, nonischemic etiology, LV end-diastolic diameter <40 mm/m(2), and septal flash by echocardiography were integrated in 4 scoring systems...

BACKGROUND: Implantable cardioverter defibrillators (ICDs) are effective in terminating lethal arrhythmias, but little is known about the degree of healthcare utilization (HCU) after ICD therapies. OBJECTIVE: Utilizing data from the Managed Ventricular Pacing (MVP) trial, we sought to identify the incidence and types of HCU in ICD recipients after receiving ICD therapy (shocks or anti-tachycardia pacing (ATP)). METHODS: We analyzed HCU events (ventricular tachyarrhythmia (VTA)-related, heart failure (HF)-related, ICD implant procedure-related, ICD system-related, or other) and their association with ICD therapies (shocked ventricular tachycardia (VT) episode, ATP terminated VT episode, inappropriately shocked episode)...

Advanced heart failure (A-HF) is characterized by progressive symptoms of heart failure despite optimal therapy. In patients with A-HF, ventricular arrhythmias (VAs) are common. Clinical studies evaluating different therapies to prevent VAs had very limited representation of patients with A-HF. Among antiarrhythmic drugs, only amiodarone reduces VAs, although its use may be associated with increased mortality. Catheter ablation with substrate modification is effective to achieve VA suppression in patients with A-HF, including those with left ventricular assist devices...

Metabolic syndrome (MS) is a multifactorial disease that can affect clinical outcomes in patients treated by Cardiac Resynchronization Therapy with a defibrillator (CRT-d).Ninety-one patients received a CRT-d. According to clinical diagnosis, the study population was divided into 46 MS (cases) versus 45 no MS (controls) patients. These patients were followed by clinical, instrumental assessment, and device telemetric interrogations at follow-up. The design of the study was to evaluate the functionality of the CRT-d leads, the arrhythmic events, the CRT-d response, and the clinical outcomes at follow-up...
