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.

Recent advances in heart failure
Purpose of review Acute heart failure continues to be a challenge as there is limited benefit of numerous agents that have been tested. Cardiac resynchronization therapy remains standard of care, yet timing and need for implantable cardiac defibrillator has been brought into question with the recent randomized trials. Several recent advances have been made towards management of heart failure both in drug and device therapy. The purpose of this review is to provide an update on the most important recent studies on heart failure with reduced ejection fraction (HFrEF) and heart failure with preserved ejection fraction (HFpE...

EBR Systems launches trial for wireless pacer
EBR Systems said yesterday that it launched a 350-patient investigational device exemption trial of its Wise wireless pacemaker it hopes to use to win FDA approval. Sunnyvale, Calif.-based EBR’s device uses a subcutaneous generator to wirelessly deliver ultrasound energy to a “pellet” implanted in the right ventricle, which it uses to synchronize the left and right ventricles. The system is designed to eliminate the need for a left ventricular lead by allowing the operating physician to place the stimulation “pellet” in a patient-specific location inside the left ventricle. The FDA approved the Solve-CRT stu...

Can We Use the Intrinsic Left Ventricular Delay (QLV) to Optimize the Pacing Configuration for Cardiac Resynchronization Therapy With a Quadripolar Left Ventricular Lead? Original Articles
Conclusions: The large variation in acute hemodynamic response indicates that the choice of the stimulated electrode on a quadripolar lead is important. Although QLV/QRSd was associated with acute hemodynamic response at group level, it cannot be used to select the optimal electrode in the individual patient.

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 ...

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 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...

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]

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.

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...

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...
