Recommendations for participation in leisure-time physical activity and competitive sports in patients with arrhythmias and potentially arrhythmogenic conditions: Part 1: Supraventricular arrhythmias. A position statement of the Section of Sports Cardiology and Exercise from the European Association of Preventive Cardiology (EAPC) and the European Heart Rhythm Association (EHRA), both associations of the European Society of Cardiology.

Eur J Prev Cardiol 2020 Jun 29:2047487320925635. Epub 2020 Jun 29.

Italian National Olympic Committee, Institute of Sport Medicine and Science, Italy.

Symptoms attributable to arrhythmias are frequently encountered in clinical practice. Cardiologists and sport physicians are required to identify high-risk individuals harbouring such conditions and provide appropriate advice regarding participation in regular exercise programmes and competitive sport. The three aspects that need to be considered are: (a) the risk of life-threatening arrhythmias by participating in sports; (b) control of symptoms due to arrhythmias that are not life-threatening but may hamper performance and/or reduce the quality of life; and (c) the impact of sports on the natural progression of the underlying arrhythmogenic condition.

Endovascular Neuromodulation: Safety Profile and Future Directions.

Front Neurol 2020 24;11:351. Epub 2020 Apr 24.

Department of Medicine, Vascular Bionics Laboratory, Melbourne Brain Centre, The University of Melbourne, Melbourne, VIC, Australia.

Endovascular neuromodulation is an emerging technology that represents a synthesis between interventional neurology and neural engineering. The prototypical endovascular neural interface is the Stentrode, a stent-electrode array which can be implanted into the superior sagittal sinus via percutaneous catheter venography, and transmits signals through a transvenous lead to a receiver located subcutaneously in the chest. Whilst the Stentrode has been conceptually validated in ovine models, questions remain about the long term viability and safety of this device in human recipients. Read More

Heart failure management in dialysis patients: Many treatment options with no clear evidence.

Semin Dial 2020 05 13;33(3):198-208. Epub 2020 Apr 13.

William B. Schwartz MD Division of Nephrology, Tufts Medical Center, Boston, MA, USA.

Heart failure with reduced ejection fraction (HFrEF) impacts approximately 20% of dialysis patients and is associated with high mortality rates. Key issues discussed in this review of HFrEF management in dialysis include dialysis modality choice, vascular access, dialysate composition, pharmacological therapies, and strategies to reduce sudden cardiac death, including the use of cardiac devices. Peritoneal dialysis and more frequent or longer duration of hemodialysis may be better tolerated due to slower ultrafiltration rates, leading to less intradialytic hypotension and better volume control; dialysate cooling and higher dialysate calcium may also have benefits.

Clinical safety of ProMRI implantable cardioverter-defibrillator systems during head and lower lumbar magnetic resonance imaging at 1.5 Tesla.

Sci Rep 2019 12 3;9(1):18243. Epub 2019 Dec 3.

High-Field and Hybrid MR Imaging, University Hospital Essen, Essen, Germany.

Magnetic resonance imaging (MRI) has long been contraindicated in patients with implanted pacemakers, defibrillators, and cardiac resynchronisation therapy (CRT) devices due to the risk of adverse effects through electromagnetic interference. Since many recipients of these devices will have a lifetime indication for an MRI scan, the implantable systems should be developed as 'MRI-conditional' (be safe for the MRI environment under predefined conditions). We evaluated the clinical safety of several Biotronik ProMRI ('MRI-conditional') defibrillator and CRT systems during head and lower lumbar MRI scans at 1. Read More

Trends of Sex Differences in Outcomes of Cardiac Electronic Device Implantations in the United States.

Can J Cardiol 2020 Jan 22;36(1):69-78. Epub 2019 Aug 22.

Keele Cardiovascular Research Group, Centre for Prognosis Research, Institutes of Applied Clinical Science and Primary Care and Health Sciences, Keele University, Stoke-on-Trent, Staffordshire, United Kingdom; Royal Stoke University Hospital, Stoke-on-Trent, United Kingdom. Electronic address:

Background: The disparity in outcomes of cardiac electronic device implantations between sexes has been previously demonstrated in device-specific cohorts (eg, implantable cardioverter-defibrillators [ICDs]). However, it is unclear whether sex differences are present with all types of cardiac implantable electronic devices (CIEDs) and, if so, what the trends of such differences have been in recent years.

Methods: With the use of the National Inpatient Sample, all hospitalizations from 2004 to 2014 for de novo implantation of permanent pacemakers, cardiac resynchronization therapy with or without a defibrillator, and ICDs were analyzed to examine the association between sex and in-hospital acute complications of CIED implantation.

Cardiac conduction devices in the radiologic comparative identification of decedents.

Forensic Sci Med Pathol 2020 Mar 14;16(1):157-165. Epub 2019 Nov 14.

Department of Forensic Medicine and Imaging, Institute of Forensic Medicine, University of Zurich, Winterthurerstrasse 190/52, CH-8057, Zurich, Switzerland.

Cardiac conduction devices (CCDs), including pacemakers and implantable cardioverter-defibrillators (ICDs), are implanted in a significant part of the population, especially as the population becomes older. CCDs play an important role in forensic medicine; they are a valuable identification tool as the manufacturer information and unique serial numbers of the device can be matched with the medical records of the person of suspected identity after the device has been removed from the body. Radiological examinations such as X-ray or computed tomography (CT) can illustrate specific CCD features. Read More
