Atrial Fibrillation Management in Heart Failure: Interrupting the Vicious Cycle
AbstractPurpose of reviewIn this review article, we aim to describe the pathophysiology of concomitant atrial fibrillation and both left and right heart failure, as well as pronounce the prognosis of having these two conditions simultaneously. This review also summarizes the current management of atrial fibrillation including stroke and thromboembolism prevention in the presence of systolic and diastolic heart failure.Recent findingsWhile rhythm control strategy is not superior to rate control strategy in atrial fibrillation patients without heart failure, catheter ablation for atrial fibrillation has shown to improve outc...

Nonpharmacological Treatment of Atrial Fibrillation: What Is the Role of Device Therapy?
Int J Angiol DOI: 10.1055/s-0040-1708529Atrial fibrillation is the most common arrhythmia in the adult population, and its incidence and prevalence are still rising. Cardiac devices are widely used in clinical practice in the management of various rhythm disturbances and heart failure treatment. Many patients who receive a pacemaker, implantable cardioverter-defibrillator, or cardiac resynchronization therapy also experience atrial fibrillation in the course of their life. Therefore, this review aims to describe the role of these devices in the treatment and prevention of atrial fibrillation in the device recipients. In ad...

Impact of diabetes on clinical outcome of patients with heart failure undergoing ICD and CRT procedures: results from the German Device Registry
ConclusionsThe overall risk of periprocedural complications and short ‐term (1 year) clinical outcome in patients with DM and HF undergoing ICD or CRT defibrillator (CRT‐D) implantation was not increased. In contrast, CKD was associated with an increased risk of 1 year MACCE in HF patients undergoing ICD/CRT‐D implantation.

ICDs Have Come a Long Way in 40 Years
Michel Mirowski and his colleagues gave the field of implantable cardioverter-defibrillators (ICDs) a pretty good start, but what's more impressive is how far the technology has advanced since that first human ICD implant in February 1980. In the past 40 years we've seen ICDs become dramatically smaller, longer lasting, more capable, more personalized, subcutaneous (non-transvenous), and even MRI-firendly. And that's not to mention the advanced data connectivity and monitoring capabilities that the latest technologies offer. So without further ado, let's take a look at the current ICD landscape and the companie...

Effects of remote monitoring of cardiac implantable electronic devices after stroke or transient ischemic attack
Conclusion We found that remote monitoring as compared with conventional in-hospital visits may contribute to a better outcome in CIED recipients who had suffered from an ischemic cerebral event.

Left Ventricular Assist Devices (LVADS): History, Clinical Application and Complications.
Authors: Eisen HJ Abstract Congestive heart failure is a major cause of morbidity and mortality as well as a major health care cost in the developed world. Despite the introduction of highly effective heart failure medical therapies and simple devices such as cardiac resynchronization therapy that reduce mortality, improve cardiac function and quality of life, there remains a large number of patients who do not respond to these therapies or whose heart failure progresses despite optimal therapy. For these patients, cardiac transplantation is an option but is limited by donor availability as well as co-morbidities w...

Combined flow-based imaging assessment of optimal cardiac resynchronization therapy pacing vector: a  case report
ConclusionThis clinical case offers an innovative and accurate approach for acute echocardiographic optimization of left pacing vector. It shows clinical utility of combined three-dimensional full-volume color Doppler transthoracic echocardiography/echo-particle imaging velocimetry assessment to increase response to cardiac resynchronization therapy, in terms of reduction of functional mitral regurgitation, improving fluid dynamics synchrony of the left ventricle.

Temporal Trends of Cardiac Implantable Electronic Device Implantations: a Nationwide Population-based Study.
CONCLUSIONS: The number of CIED implantation increased substantially from 2009 to 2016 in Korea. Also, the patients with CIED have been changed to be older and have more comorbidities. Therefore, the burden of health care cost in patients with CIED would be expected to increase in the future. PMID: 31074230 [PubMed - as supplied by publisher]

Age-Dependence of Flow Homeostasis in the Left Ventricle
Conclusions: In average, blood spends 1 to 3 beats inside the LV with very low shear stress rates. The apical region is the most prone to blood stasis, particularly in mid-aged adults. The washout of blood in the normal LV is age-dependent due to physiological changes in the degree of apical penetration of the filling waves. Introduction Cardioembolic stroke is a major source of mortality and disability worldwide and blood stasis one of its major determinants (Adams et al., 1986). Left ventricular (LV) function has evolved to maximize mechanical efficiency and ensure organ perfusion at a low cost of energy and fill...

Device Therapy and Arrhythmia Management in Left Ventricular Assist Device Recipients: A Scientific Statement From the American Heart Association.
linical Cardiology; and Council on Cardiovascular and Stroke Nursing Abstract Left ventricular assist devices (LVADs) are an increasingly used strategy for the management of patients with advanced heart failure with reduced ejection fraction. Although these devices effectively improve survival, atrial and ventricular arrhythmias are common, predispose these patients to additional risk, and complicate patient management. However, there is no consensus on best practices for the medical management of these arrhythmias or on the optimal timing for procedural interventions in patients with refractory arrhythmias. Altho...

Is resynchronization therapy really efficient in laminopathy?
ConclusionCardiac resynchronization therapy seems to be less efficient in LMNA patients compared to usual implanted patients with other type of advanced cardiomyopathy. An impaired right ventricular stroke function seems to be the only predictive factor leading to poor response to CRT.

Device-Detected Atrial Fibrillation: Evidencing the Knowledge Gap.
Abstract Stroke is a devastating complication of atrial fibrillation (AF) the odds of which can be reduced by use of oral anticoagulation based on the stroke risk score.1,2 Patients with asymptomatic clinical AF have a similar stroke risk as patients with symptomatic clinical AF.3 Thus far, electrocardiographic- (ECG) or Holter monitor-detected AF is a prerequisite before use of oral anticoagulation,1,2 because the guideline recommendations are based on studies that included only ECG- or Holter-detected AF ('clinical' AF).1,2 In the past decades increasing number of cardiac implantable electronic devices (CIED) ha...

Incidence, Clinical Characteristics, and Long-term Outcome of the Dilated Phase of Hypertrophic Cardiomyopathy.
Abstract Some patients with hypertrophic cardiomyopathy (HCM) develop systolic dysfunction, called the dilated phase of HCM (d-HCM), which is associated with increased morbidity and mortality. We conducted a retrospective study using an HCM database to clarify the incidence, clinical characteristics, and long-term outcomes of d-HCM. We analyzed an HCM cohort consisting of 434 patients (273 with apical HCM and 161 with non-apical HCM; 18 had obstructive HCM, 16 had dilated HCM, and 127 had other HCM) diagnosed by echocardiography in our hospital between 1991 and 2010. The follow-up period was 8.4 ± 6.7 years. The ...

Estimating the incidence of atrial fibrillation in single ‐chamber implantable cardioverter defibrillator patients
ConclusionsAtrial arrhythmias occur frequently, and significant underutilization of anticoagulation is suggested in single ‐chamber ICD recipients. Routine screening for AF should be considered among single‐chamber ICD recipients.This article is protected by copyright. All rights reserved

Subclinical atrial fibrillation frequency and associated parameters in patients with cardiac resynchronization therapy
ConclusionPatients with CRT have significantly higher frequency of SCAF than the normal population. CHA2DS2-VASc score, LA diameter, and atrial threshold values were considered to be useful and easily applicable parameters in identifying the patients to develop SCAF.
