BACKGROUND: Heart Rate Score (HRSc)≥70%, a novel parameter, predicts risk of mortality in patients with implantable defibrillators and identifies patients who have survival benefit with DDDR versus DDD pacing. OBJECTIVE: DDDR pacing lowers HRSc and dual-sensor with minute ventilation (MV) and accelerometer (XL) improves HRSc more than accelerometer (XL) alone in patients requiring pacemakers (PM). METHODS: HRSc, the percent of all beats in the predominant 10 bpm bin, was calculated...

BACKGROUND: The subcutaneous implantable cardioverter-defibrillator (S-ICD) lacks the antitachycardia pacing (ATP) capability of tranvenous ICDs (TV-ICD). S-ICD patient selection can be challenging as some patients may benefit from ATP. We aim to identify clinical predictors of ATP benefit, in order to improve patient selection for S-ICD or TV-ICD therapy. METHODS: De novo single- and dual-chamber TV-ICD patients implanted between March 2011 and December 2015 were included...

A 72-year-old man with a dual-chamber implantable defibrillator was referred to our center for transvenous lead extraction because of pocket infection and presence of an abandoned lead. We decided to proceed with a video-assisted thoracoscopic approach because of patient history and documented complete occlusion of the right subclavian vein. During the use of excimer laser for persistent adhesions, the ventricular lead broke down at the level of cavoatrial junction. To successfully remove the remaining portion of lead, we decided to use the excimer laser by femoral route...

BACKGROUND: In the United States, over 350,000 cardiac arrests occur outside of the hospital and 209,000 occur in the hospital. Shockable rhythms such as ventricular fibrillation (VF) have a survival rate of 20-30% outside of the hospital setting. Dual Sequential Defibrillation (DSD) has demonstrated success in terminating VF that is refractory to multiple attempts using a single defibrillator. METHODS: The PubMed, and MEDLINE databases were reviewed in February of 2018 and literature reviewed on dual sequential defibrillation...

Dual-chamber implantable cardioverter-defibrillator is generally used in patients with atrioventricular block and hypertrophic cardiomyopathy with preserved left ventricular ejection fraction. In the current case, a cardiac resynchronization therapy-defibrillator device was implanted in a patient with non-obstructive hypertrophic cardiomyopathy with preserved ejection fraction and atrioventricular block to achieve both more physiological pacing and life-threatening ventricular arrhythmia management.

We herein report the successful treatment of a 4-year-old girl with left ventricular noncompaction (LVNC) who presented with incessant ventricular fibrillation at 5 months of age. An implantable cardioverter defibrillator (ICD) was implanted, and dual chamber (DDD) pacing was initiated at 7 months of age. At her 10-month follow-up, her left ventricular ejection fraction (LVEF) had decreased from 45% to 20% with mechanical dyssynchrony. After upgrading to cardiac resynchronization therapy (CRT), the LVEF improved to 50%...

Aims: Comparison of outcomes between subcutaneous and transvenous implantable cardioverter-defibrillator (S-ICD and TV-ICD) therapy is hampered by varying patient characteristics and complication definitions. The aim of this analysis is to compare clinical outcomes of S-ICD and TV-ICD therapy in a matched cohort. Methods and results: Patients implanted with de novo implantable cardioverter-defibrillators without need for pacing were selected from two studies: SIMPLE (n = 1091 single and n = 553 dual chamber TV-ICDs) and EFFORTLESS (n = 798 S-ICDs)...

OBJECTIVES: This study sought to evaluate the effects of programming a long detection in single-chamber (VVI) implantable cardioverter-defibrillators (ICDs) in the multicenter prospective ADVANCE III (Avoid DeliVering TherApies for Non-sustained Arrhythmias in ICD PatiEnts III) trial. BACKGROUND: Programming strategies may reduce unnecessary ICD shocks and their adverse effects but to date have been described only for dual-chamber ICDs. METHODS: A total of 545 subjects (85% male; atrial fibrillation 25%, left ventricular ejection fraction 31%, ischemic etiology 68%, secondary prevention indications 32%) receiving a VVI ICD were randomized to long detection (30 of 40 intervals) or standard programming (18 of 24 intervals) based on device type, atrial fibrillation history, and indication...

OBJECTIVES: This analysis evaluated temporal trends and factors associated with the use of dual-coil implantable cardioverter-defibrillator (ICD) leads. BACKGROUND: Data suggest that dual-coil ICD leads are not associated with lower mortality and can be more difficult to extract than single-coil leads. METHODS: A total of 435,772 patients at 1,690 hospitals underwent ICD lead insertion in the National Cardiovascular Data Registry's ICD Registry between April 2010 and December 2015...

RATIONALE: Inadvertent pacemaker/defibrillator lead placement into the left ventricle is an unusual cardiac device-related complication and its diagnosis is not always easy and often misunderstood. Thromboembolic events are frequently associated with this procedural complication. Percutaneous lead extraction should be performed when diagnosis is made early after device implantation while long-life oral anticoagulation is a wise option when the diagnosis is delayed and the lead is not removed...

In the setting of cardiac arrest, refractory ventricular fibrillation (VF) is difficult to manage, and mortality rates are high. Double sequential defibrillation (DSD) has been described in the literature as a successful means to terminate this malignant rhythm, after failure of traditional Advanced Cardiac Life Support (ACLS) measures. The authors herein present a case of refractory VF in a patient with cardiac arrest, on whom DSD was successful in reversion to sinus rhythm, and provide a thorough review of similar cases in the literature...

Patients with cardiac implantable electronic devices (CIED) and endovascular infection represent a difficult management group. The explantation of an implantable cardioverter-defibrillator (ICD) system deprives the patient of the protection against life-threatening ventricular tachyarrhythmias. In this study, we describe feasibility and clinical outcomes of bridging with temporary dual-coil ICD lead and external ICD following the extraction of a CIED due to endovascular infection and compare the performance of this approach to other available options...

BACKGROUND: Implantable hypoglossal nerve upper airway stimulation (HNS) is a novel strategy approved by the US Food and Drug Administration for the management of moderate-to-severe obstructive sleep apnea (OSA) in patients with continuous positive airway pressure therapy intolerance or failure. Because of the proximity of a cardiac implantable electronic device (CIED) to this stimulator, interaction between these devices is theoretically possible. OBJECTIVE: The purpose of this study was to assess interactions between an implantable HNS device and a CIED...

We performed a retrospective review of 402 consecutive patients who underwent heart transplantation at our institution between January 2009 and March 2017. A retained cardiovascular implantable electronic device (CIED) fragment was identified after transplantation in 49 of the 301 patients (16.2%) with CIED at baseline. Patients with retained fragments had leads with longer dwell times (median 2596 [1982, 3389] vs 1384 [610, 2202] days, P < .001), higher prevalence of previously abandoned leads (14.3% vs 2...

BACKGROUND: The Biotronik DX lead is an attractive option due to its floating atrial bipole and its noninferiority compared to dual-chamber defibrillators. METHODS: We describe the case of atrial undersensing by the DX lead resulting in failure of the device to appropriately treat a slow ventricular tachycardia. CONCLUSION: This case underlies the importance of understanding the limitations to each lead technology as well as the underlying assumptions inherent to detection enhancement algorithms...
