BACKGROUND: Implantable hypoglossal nerve upper airway stimulation (HNS) is a novel, FDA approved strategy for management of moderate to severe obstructive sleep apnea(OSA) patients with continuous positive airway pressure (CPAP) therapy intolerance or failure. Due to proximity of Cardiac Implantable Electronic Devices (CIED) and this stimulator, interaction between these devices is theoretically possible. OBJECTIVE: The purpose of this study was to assess interactions between implantable hypoglossal nerve upper airway stimulator device and cardiac implantable electronic devices...

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<0.001), 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 non-inferiority 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...

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...

Kearns-Sayre syndrome (KSS), a rare form of mitochondrial myopathy, is a triad of chronic progressive external ophthalmoplegia, bilateral pigmentary retinopathy, and cardiac conduction abnormalities. In this report, we show how a combined spinal epidural anesthesia can be useful for cesarean delivery, as we illustrate in a dual-chamber and VVI implantable defibrillator pacemaker/defibrillator parturient with a KSS and preeclampsia.

OBJECTIVES: Pacemakers and implantable cardioverter defibrillators have become more common in younger individuals, owing to broader indications and technological advances. Our goal was to report our long-term experience of implanting cardiac devices in young adults via a subaxillary approach with a hidden single incision, to minimize the aesthetic impact of the device. METHODS: From 2003 to 2012, 23 patients underwent cardiac device implantation via a subaxillary approach while they were under general anaesthesia...

A man with non-ischemic cardiomyopathy, EF 22%, permanent AF and ICD was admitted for elective device replacement. The need for the optimization of the ventricular rate and avoidance of right ventricular pacing made it necessary to up-grade the existing pacing system using direct His bundle pacing and dual chamber ICD. This enabled the regularization of ventricular rate, avoiding the RV pacing and optimize the beta-blocker dose. The one month follow-up already showed reduction in left ventricle diameter, improvement in ejection fraction, NYHA class decrease to II...
