REVIEW
Merrill H Stewart, Daniel P Morin
Periprocedural management of anticoagulation for cardiac device implantation has evolved over the past 20 years. The traditional paradigm of vitamin K antagonist interruption with heparin bridging has now been shown to be less safe than continuation of vitamin K antagonists at therapeutic levels. Dual antiplatelet therapy during device implantation poses substantial risk but is often necessary. The safest dosing strategy for newer direct oral anticoagulants is still not clear.

REVIEW

Long-term right ventricular apical pacing has been associated with detrimental effects, including an increased risk for heart failure, atrial fibrillation, and death. Most of these adverse effects result from ventricular dyssynchrony related to perturbed ventricular depolarization. In addition, biventricular pacing has limited benefits in patients with non-left bundle branch block and severely reduced ejection fraction. Consequently, alternative pacing strategies that mimic natural physiology are desired. Recently, permanent His bundle pacing has emerged as a true physiologic form of ventricular pacing that has been shown to be safe and feasible in clinical practice...

REVIEW
Jeremiah Wasserlauf, Rod S Passman
Device-detected atrial high-rate episodes (AHREs) are frequently encountered in patients with no history of atrial fibrillation (AF) and represent a challenge for clinicians because patients with device-only documented AF have not been included in clinical trials of anticoagulants and other AF therapies. For patients with known history of AF, wireless continuous rhythm monitoring and rapidly acting oral anticoagulants offer the possibility of tailored anticoagulation in response to AHREs, with studies ongoing to evaluate the safety of this approach...

REVIEW
Nitin Kulkarni, Mark S Link
Use of implantable cardioverter-defibrillators as a primary prevention therapy has been shown to reduce mortality in patients after cardiac arrest and also with left ventricular systolic dysfunction. Yet, inappropriate shocks are variably reported and associated with a reduction in quality of life. Inappropriate shocks are the result of environmental causes leading to electromagnetic interference and inappropriate sensing of external noise, device-related causes from inappropriate sensing of physiologic or pathologic signals, and supraventricular arrhythmias...

#7
REVIEW
Fahad Almehmadi, Jaimie Manlucu
The historical preference for dual-coil implantable cardioverter defibrillator leads stems from high defibrillation thresholds associated with old device platforms. The high safety margins generated by contemporary devices have rendered the modest difference in defibrillation efficacy between single- and dual-coil leads clinically insignificant. Cohort data demonstrating worse lead extraction outcomes and higher all-cause mortality have brought the incremental utility of an superior vena cava coil into question...

REVIEW
Maki Ono, Niraj Varma
This review aims to cover the latest evidence of remote monitoring of cardiac implantable electronic devices for the management of atrial fibrillation and heart failure. Remote monitoring is useful for early detection for device-detected atrial fibrillation, which increases the risk of thromboembolic events. Early anticoagulation based on remote monitoring potentially reduces the risk of stroke, but optimal alert setting needs to be clarified. Multiparameter monitoring with automatic transmission is useful for heart failure management...

REVIEW
Tharian S Cherian, Gaurav A Upadhyay
Long-term right ventricular pacing is associated with electrical and mechanical dyssynchrony and ultimately development of pacing-induced cardiomyopathy (PICM) in a subset of patients. Patients with a high degree of pacing burden and reduced left ventricular (LV) function prior to pacemaker implantation are at the greatest risk for developing PICM. Cardiac resynchronization therapy (CRT) has an established role in the treatment of patients with LV systolic heart failure and intraventricular delay and has been used to successfully treat PICM...

Leadless pacemaker therapy is a new technology that aims at avoiding lead- and pocket-related complications of conventional transvenous and epicardial pacing. To date, 2 self-contained leadless pacemakers for right ventricular pacing have been clinically available: the Nanostim Leadless Pacemaker System and the Micra Transcatheter Pacing System. Additionally, a new multicomponent leadless pacemaker for endocardial left ventricular pacing has been proposed as an alternative choice for cardiac resynchronization therapy...

REVIEW
Jose M Marcial, Seth J Worley
Subclavian obstruction is common after lead implantation and the need to add or replace a lead is increasing. Subclavian venoplasty (SV) is a safe and effective option for venous occlusion. Peripheral venography overestimates the severity of the obstruction. A wire can usually be advanced into the central circulation for SV. Compared with dilators, SV improves the quality of venous access, providing unrestricted catheter manipulation for His bundle pacing and left ventricular lead implantation. SV preserves venous access and reduces lead burden...

REVIEW
Khalid Aljabri, Ann Garlitski, Jonathan Weinstock, Christopher Madias
The rate of cardiac implantable electronic device (CIED) infection has increased disproportionately to the rate of implantation. Expanded indications for CIED implantation combined with a sicker patient population contribute to this increased rate. Device-related infections are most commonly due to perioperative contamination, and infection risk increases in conjunction with procedural complexity. Early pocket re-exploration and upgrade procedures confer a higher infectious risk. Confirmed CIED infection requires prompt removal of the CIED system combined with antimicrobial therapy...

The efficacy of implantable cardioverter defibrillators in reducing the risk of sudden cardiac death has been well established by several clinical trials. Several factors relating to device characteristics, patient attributes, and comorbidities should be considered when selecting the appropriate implantable cardioverter defibrillators for each patient. This review examines some of these issues.

The implantable cardioverter defibrillator (ICD) is a life-saving therapy in various patient populations. Although data on the outcomes of initial ICD implants are abundant, data on ICD replacements, especially in patients with improved left ventricular (LV) function, are scarce. Therefore, it is not known when it is safe to not replace an ICD that has reached the end of battery life. This article reviews data on patients with primary prevention ICDs who have improvement in left ventricular ejection fraction during follow-up and provides some guidance, based on the available evidence, related to circumstances when replacement of an ICD may be forgone...

REVIEW
Charles J Love
Management of patients with cardiac implantable electronic devices (CIEDs) has become complex given the complications that can occur with implanted lead systems. Clinical problems such as infection, lead failure, and occluded vessels create situations that demand intervention to remove leads. Due to adhesions that occur in the venous system and at the endomyocardial attachment site, simple traction to remove a lead is often not sufficient. Infection is a mandatory reason to remove the entire CIED system. Tools and techniques are now available that enable a skilled operator to extract leads with a great deal of efficacy and safety...

Defibrillation testing (DFT) during implantable cardioverter-defibrillator (ICD) implantation is still considered standard of care in some, but in increasingly fewer centers. The goal is to ensure that the device system functions as intended by testing in the controlled laboratory setting. Although safe, complications can occur and DFT is associated with an increased procedural time and cost. DFT is useful in assessing device function when programming changes or patient characteristics raise concerns regarding ICD efficacy...

Cryptogenic stroke (CS) represents 10%-40% of ischemic strokes and is associated with significant morbidity and mortality and high risk of recurrence. Undetected atrial fibrillation is an important consideration in these patients. Tools for electrocardiographic monitoring range from 12-lead electrocardiogram to implantable loop recorders (ILRs). ILRs have become an important tool for long-term electrocardiogram monitoring in CS patients. Advancements in ILR technology are needed to ensure more robust connectivity and to help triage incoming data...

REVIEW
Jonathan Weinstock
The wearable cardioverter defibrillator has been shown to be effective in terminating ventricular arrhythmias in patients at risk for sudden cardiac death. There are numerous scenarios in which implant of a permanent implantable cardioverter defibrillator is temporarily contraindicated or not advisable and a wearable cardioverter defibrillator may be beneficial. There are no prospective randomized studies published that provide conclusive guidance toward the use of the wearable cardioverter defibrillator, and thus, patient management needs to be individualized based on the available data...

Battery depletion is the most common reason for device reoperation, which is associated with significant patient morbidity and mortality. This article describes the history of pacing and defibrillation power supplies and the factors that determine the longevity of pacing and defibrillator generators with a special emphasis on factors that can be adjusted or controlled by the implanting and following physician. Optimization of longevity is attained through device selection; shock minimization; avoidance of prolonged radiofrequency telemetry; selection of higher impedance vectors; avoidance of long pulse duration when possible; and avoidance of unnecessary feature activation, such as continuous electrogram storage...
