Anti-arrhythmic therapy in patients with non-ischemic cardiomyopathy.

Pharmacol Res 2019 Mar 4;143:27-32. Epub 2019 Mar 4.

Division of Cardiology, McGill University Health Center, Montreal, Canada. Electronic address:

Implantable cardiac defibrillators (ICD) are the foundation of therapy for the prevention of sudden cardiac death. While ICDs prevent SCD, they do not prevent the occurrence of ventricular arrhythmias which are usually symptomatic. Though catheter ablation has been successful in substrate modification of ventricular tachycardia in patients with ischemic cardiomyopathy, there is much less evidence to support its use in non-ischemic cardiomyopathy.

Experts of the Heart Rhythm Section of the Polish Cardiac Society: opinion on the use of wearable cardioverter-defibrillators in Poland.

Kardiol Pol 2019 ;77(2):238-243

Department of Cardiology, SMDZ in Zabrze, Medical University of Silesia, Katowice, Poland.

Sudden cardiac death (SCD) is one of the main causes of mortality in developed countries. Implantable cardioverter-defibrillators (ICDs) have become a widely used and efficient method for SCD prevention in high-risk populations. Nevertheless, there are clinical situations in which the benefit of ICD is uncertain, such as: early postinfarction left ventricular dysfunction, reversible causes of cardiomyopathy, presence of temporary or permanent ICD contraindications in high-risk populations, or when ICD is not accepted by SCD prevention candidates.

Leakage current from transvenous and subcutaneous implantable cardioverter defibrillators (ICDs): A risk to the rescuer?

Resuscitation 2019 Feb 19;137:148-153. Epub 2019 Feb 19.

NIHR Respiratory BRU, University Hospital Southampton, Southampton SO16 6YD, UK. Electronic address:

Background Implantable cardioverter-defibrillators (ICDs) are a well-established therapy for patients at risk of life-threatening ventricular arrhythmias. With rising implant rates, the risk of a rescuer performing chest compressions during discharge is increasing, leading to concerns over rescuer safety from the resultant leakage current. More recently, subcutaneous ICDs (S-ICD) have been developed, which utilise a higher energy and more superficial electrodes compared with transvenous ICDs (T-ICD), raising safety concerns further.

Feasibility of Cardiac Magnetic Resonance Wideband Protocol in Patients With Implantable Cardioverter Defibrillators and Its Utility for Defining Scar.

Am J Cardiol 2019 Jan 31. Epub 2019 Jan 31.

University of Chicago Medical Center, Chicago, Illinois. Electronic address:

Implantable cardioverter defibrillators (ICDs) have been a relative contraindication to cardiovascular magnetic resonance imaging. Although cardiovascular magnetic resonance provides valuable information regarding scar in patients with ventricular arrhythmias or cardiomyopathy, ICDs in these patients frequently cause artifacts hindering accurate interpretation of both cine and late gadolinium enhancement (LGE) images. We sought to quantify the frequency and severity of artifact on LGE images and assess whether a modified wideband LGE protocol could improve the diagnostic yield of scar identification in agreement with invasive electroanatomic mapping (EAM).

Driving with Cardiac Devices in Australia. Does a review of recent evidence prompt a change in guidelines?

Intern Med J 2019 Feb 6. Epub 2019 Feb 6.

Victorian Institute of Forensic Medicine, Monash University.

Australian Driving Guidelines for patients with pacemakers and implanted cardioverter defibrillators are in line with many around the world, with some minor differences. Some aspects of these guidelines lack contemporary evidence in key decision making areas and make broad recommendations regarding groups with heterogeneous populations. Additionally, more recent studies suggest lower rates of adverse events in some patients with these devices than previously thought. Read More

Inappropriate Defibrillator Shocks due to Mechanical Inference from an Investigational Device.

Case Rep Cardiol 2019 6;2019:2810396. Epub 2019 Jan 6.

Dayton Heart and Vascular Hospital, Dayton, OH, USA.

Cardiac contractility modulation (CCM) is an investigational device-based therapy to enhance ventricular contractility in systolic heart failure patients who are not candidates for cardiac resynchronization therapy (CRT) owing to the absence of wide QRS complexes or who have failed to respond on CRT. The principal mechanism is based on the stimulation of cardiac muscles by nonexcitatory electrical signals to augment the influx of calcium ions into the cardiomyocytes. The majority of patients receiving CCM therapy have concurrent implantable cardioverter defibrillators, and the manufacturer declares both devices can be used in parallel without any interactions.

Device Programming for His Bundle Pacing.

Circ Arrhythm Electrophysiol 2019 Feb;12(2):e006816

Geisinger Commonwealth School of Medicine, Geisinger heart Institute, Wilkes Barre, PA (P.V.).

Although permanent His bundle pacing was first reported almost 2 decades ago, it is only recently gaining wider adoption, following facilitation of the implant procedure by dedicated tools. An additional challenge is programming the system, as His bundle pacing may have specific configurations and require special considerations which current implantable pulse generators are not designed for. The aim of this article is to provide practical recommendations for programming His bundle pacing, to deliver optimal therapy and ensure patient safety. Read More

Right ventricular pacing is associated with increased rates of appropriate implantable cardioverter defibrillator shocks.

Ann Noninvasive Electrocardiol 2019 Feb 5:e12636. Epub 2019 Feb 5.

Section of Cardiology, Rady Faculty of Health Sciences, University of Manitoba, Winnipeg, Manitoba, Canada.

Background: Right ventricular (RV) pacing has been associated with increased risk of pacemaker-induced cardiomyopathy, hospitalization and death among patients with implantable cardioverter defibrillators (ICDs). Little is known about its association with ventricular tachyarrhythmias. We hypothesize that RV pacing is associated with increased incidence of appropriate ICD shocks and death. Read More

Managing Implantable Cardioverter-Defibrillators at End-of-Life: Practical Challenges and Care Considerations.

Am J Med Sci 2019 Feb 29;357(2):143-150. Epub 2018 Nov 29.

Division of Cardiology, University of Texas Southwestern Medical Center, Dallas, Texas. Electronic address:

Implantable cardioverter-defibrillators (ICDs) monitor for and terminate malignant arrhythmias. Given their potential as a life-saving therapy, an increasing number of people receive an ICD every year, and a growing number are currently living with ICDs. However, cardiopulmonary arrest serves as the final common pathway of natural death, and the appropriate management of an ICD near the end-of-life is crucial to ensure that a patient's death is not marked by further suffering due to ICD shocks.
