BACKGROUND: Recent evidence has shown that adaptive servo-ventilation (ASV) is contraindicated in patients with predominant central sleep apnea (CSA) and reduced left ventricular ejection fraction (LVEF ≤45%). The objective of this study was to assess the clinical usage of ASV in patients at the time-point of the release of a safety warning by type of SDB, breathing pattern and LVEF. METHODS: Patients of a cardiac and a respirology sleep center, both in Germany, who received ASV therapy were contacted between May and October 2015...

INTRODUCTION: Adaptive servo-ventilation (ASV) therapy is a recently developed non-pharmacological therapy that has been reported to improve cardiac function and survival in patients with severe congestive heart failure (CHF). However, a recent large randomized study suggested that ASV does not improve survival in patients with reduced ejection fraction. It remains unclear whether ASV treatment can reduce the hospitalization rate of CHF patients. We thus examined the frequency of hospital admission before and after initiation of ASV therapy in patients with CHF...

INTRODUCTION: Both types of sleep-disordered breathing (SDB), obstructive and central sleep apnoea (OSA and CSA, respectively), are common in patients with heart failure and reduced ejection fraction (HFrEF). In such patients, SDB is associated with increased cardiovascular morbidity and mortality but it remains uncertain whether treating SDB by adaptive servo-ventilation (ASV) in such patients reduces morbidity and mortality. AIM: ADVENT-HF is designed to assess the effects of treating SDB with ASV on morbidity and mortality in patients with HFrEF...

BACKGROUND: Sleep apnea is common in hospitalized heart failure (HF) patients and is associated with increased morbidity and mortality. OBJECTIVES: The CAT-HF (Cardiovascular Improvements With MV-ASV Therapy in Heart Failure) trial investigated whether minute ventilation (MV) adaptive servo-ventilation (ASV) improved cardiovascular outcomes in hospitalized HF patients with moderate-to-severe sleep apnea. METHODS: Eligible patients hospitalized with HF and moderate-to-severe sleep apnea were randomized to ASV plus optimized medical therapy (OMT) or OMT alone (control)...

Although adaptive servo-ventilation (ASV) therapy has beneficial effects on chronic heart failure (CHF), a relatively large number of CHF patients cannot undergo ASV therapy due to general discomfort from the mask and/or positive airway pressure. The present study aimed to clarify baseline patient characteristics which are associated with the smooth introduction of ASV treatment in stable CHF inpatients.Thirty-two consecutive heart failure (HF) inpatients were enrolled (left ventricular ejection fraction (LVEF) < 45%, estimated glomerular filtration rate (eGFR) > 10 mL/minute/1...

The recent SERVE HF study concluded that patients with chronic heart failure (CHF) and Cheyne-Stokes respiration (CSR) have increased mortality when treated with adaptive servo-ventilation (ASV). We, therefore, wanted to explore if these patients tolerated discontinuation of ASV treatment. The study was a prospective post-ASV treatment observational design with a 3-month follow-up period. 14 patients from our outpatient clinic, all male, were originally diagnosed with CHF and Cheyne-Stokes respiration, which is a clinical form of central sleep apnea...

Central sleep apnea (CSA) and obstructive sleep apnea (OSA) are prevalent in heart failure (HF) and associated with a worse prognosis. Nocturnal oxygen therapy may decrease CSA events, sympathetic tone, and improve left ventricular ejection fraction, although mortality benefit is unknown. Although treatment of OSA in patients with HF is recommended, therapy for CSA remains controversial. Continuous positive airway pressure use in HF-CSA may improve respiratory events, hemodynamics, and exercise capacity, but not mortality...

BACKGROUND: Adaptive servo-ventilation (ASV) therapy is a recent non-invasive positive pressure ventilation therapy that was developed for patients with heart failure (HF) refractory to optimal medical therapy. However, it is likely that ASV therapy at relatively higher pressure setting worsens some of the patients' prognosis compared with optimal medical therapy. Therefore, identification of optimal pressure settings of ASV therapy is warranted. CASE PRESENTATION: We present the case of a 42-year-old male with HF, which was caused by dilated cardiomyopathy, who was admitted to our institution for evaluating his eligibility for heart transplantation...

Letter to the Editor We read with great interest the report by Inoue et al. (Cusp-level chordal shortening for non-rheumatic mitralanterior leaflet prolapse in a patient with persistent atrial fibrillation. J Heart Valve Dis 2015;24:586-589) that described their mitral valve repair technique for anterior leaflet prolapse (ALP) and perioperative adaptive servo-ventilation (ASV) therapy for preventing the recurrence of atrial fibrillation after the maze procedure. Latent recurrence of atrial fibrillation after the maze procedure is caused by many factors...

Physicians responsible for the care of patients with heart failure due to left ventricular systolic dysfunction have access to a broad range of evidence-based treatments that prolong life and reduce symptoms. In spite of the significant progress made over the last four decades, there is an ongoing need for novel therapies to treat a condition that is associated with stubbornly high morbidity and mortality. In this article, we discuss the findings of SERVE-HF, a randomised controlled trial of adaptive servo-ventilation in patients with left ventricular systolic dysfunction, as well as EMPA-REG, a study of the effects of a novel diabetic agent that may be of greater interest to heart failure specialists than diabetologists...

OBJECTIVES: The effect of long-term adaptive servo-ventilation (ASV) on cardiovascular mortality and admission rates in patients with chronic heart failure (CHF) and Cheyne-Stokes respiration (CSR) has not been much studied. The aim of this study was primarily to investigate whether ASV therapy significantly reduced these parameters. DESIGN: We included 75 CHF patients on optimal medication and CSR ≥25% of sleeping time, in New York Heart Association (NYHA) classes II-IV and left ventricular ejection fraction (LVEF) ≤ 45%...

Objective: Evidence indicates that behavioral or drug therapy may not target underlying pathophysiologic mechanisms for chronic insomnia, possibly due to previously unrecognized high rates (30%-90%) of sleep apnea in chronic insomnia patients. Although treatment studies with positive airway pressure (PAP) demonstrate decreased severity of chronic sleep maintenance insomnia in patients with co-occurring sleep apnea, sleep-onset insomnia has not shown similar results. We hypothesized advanced PAP technology would be associated with decreased sleep-onset insomnia severity in a sample of predominantly psychiatric patients with comorbid sleep apnea...

Trans-diaphragmatic intercostal hernia is a rare entity. Patient with multiple medical comorbidities, including obstructive sleep apnoea, presents with shortness of breath, leg oedema and a bulging swelling through the right chest wall. CT shows partial herniation of the right lung and liver through intercostal space and an echocardiogram reveals right heart failure. He was treated initially with continuous positive airway pressure with poor response and subsequently treated with adaptive servo ventilation with much better symptomatic relief and treatment tolerance...

INTRODUCTION: Volume assured pressure support (VAPS) and adaptive servo ventilation (ASV) are non-invasive positive airway pressure (PAP) modes with sophisticated negative feedback control systems (servomechanism), having the capability to self-adjust in real time its respiratory controlled variables to patient's respiratory fluctuations. However, the widespread use of VAPS and ASV is limited by scant clinical experience, high costs, and the incomplete understanding of propriety algorithmic differences in devices' response to patient's respiratory changes...

Chronic heart failure (CHF) has been shown to be associated with an increased incidence of sleep-disordered breathing. Whether treatment with noninvasivepositive-pressure ventilation (NPPV), including continuous positive airway pressure, bi-level positive airway pressure and adaptive servo-ventilation, improves clinical outcomes of CHF patients is still debated. 2,832 CHF patients were enrolled in our analysis. NPPV was significantly associated with improvement in left ventricular ejection fraction (39.39% vs...
