Mortality After Atrioventricular Nodal Radiofrequency Catheter Ablation With Permanent Ventricular Pacing in Atrial Fibrillation: Outcomes From a Controlled Nonrandomized Study Original Article
Conclusions— In sick AF patients with multiple comorbidities, AVNA with permanent ventricular pacing for rate control seems safe during follow-up and may be associated with lower mortality.

Atrioventricular dyssynchrony from empiric device settings is common in cardiac resynchronization therapy and adversely impacts left ventricular morphology and function
ConclusionOur study suggests that up to 50% of patients with empiric device settings have AV dyssynchrony at 6 months despite atrioventricular delay optimization (AVO) algorithms. As AV dyssynchrony is common and has proven to be modifiable, a strategic approach to Doppler echocardiography‐guided AVO after CRT is warranted, particularly in nonresponders where the LV filling pattern is fused or truncated.

Frailty syndrome: an emerging clinical problem in the everyday management of clinical arrhythmias. The results of the European Heart Rhythm Association survey
In conclusion, the complex clinical condition in frail patients presenting with arrhythmias warrants an integrated multidisciplinary approach both for the management of rhythm disturbances and for the decision on using CIEDs.

Medtronic touts reduced AF, improved activity in AdaptivCRT studies
Medtronic (NYSE:MDT) today released results from two real-world analyses of its AdaptivCRT algorithm, touting that its use was linked to a reduction in atrial fibrillation episodes and higher patient activity levels. Results from the analyses, which involved a total of 408 patients at 26 centers in Italy, were presented at the European Heart Rhythm Association’s Scientific Sessions 2018 in Barcelona, Spain, the company said. Medtronic’s AdaptivCRT algorithm is designed to adjust pacing to the heart dependent upon evaluations of heart rhythm made every minute, the company said. The program has been shown to in...

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.

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

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 ...

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]

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...

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...

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...

Diagnosis of atrial fibrillation in heart failure patients with implantable cardioverter defibrillator or cardiac resynchronisation therapy
CONCLUSIONS: Episodes of paroxysmal atrial fibrillation in patients with systolic heart failure and implanted cardioverter-defibrillator systems are quite common. The majority of the episodes recorded in the study were asymptomatic.PMID:34900037 | PMC:PMC8641502 | DOI:10.5114/aoms/114977
