Indications for pacemaker and implantable cardioverter defibrillator (ICD) implantations are rapidly expanding. Hence, device-related complications have increased the need for lead extraction. Lead extractions are performed percutaneously or by open surgery. We present a patient with isolated left ventricular noncompaction cardiomyopathy suffering from ICD pulse generator pocket and lead infect...

Device implantations may be challenging in patients with venous abnormalities. The most common congenital variation, frequently associated with other congenital abnormalities, is a persistent left superior vena cava (PLSVC), and successful atrial and ventricular lead implantation via a PLSVC have both been reported [1]. “Ratchet syndrome” has also been reported as a rare complication after a ne...

Introduction Pacemaker and implantable cardioverter-defibrillator (ICD) lead perforations are well described and may cause many complications. Delayed cardiac perforation (DCP) is a less recognized complication of device implantation and is believed to be rare. We present a case of DCP wherein 2 simultaneous ICD lead perforations occurred in the right ventricle (RV) and were overlooked on chest...

A 52-year-old man was brought to the emergency department because of multiple implantable cardioverterdefibrillator (ICD) shocks. His existing dual-chamber pacemaker was upgraded from a biventricular ICD 4 years ago. The ECG in the emergency department showed sinus tachycardia with left bundle-branch block at a rate of 135 bpm. In the emergency department, the patient received 5 additional shoc...

Introduction Persistent left superior vena cava (PLSVC) is a congenital developmental abnormality of the sinus venosus with an incidence of 0.47% in patients undergoing cardiac implantable electronic devices. The 2 variants include a double superior vena cava (right and left SVC, with or without an innominate vein connecting the two) or a single left-sided SVC (without a right SVC), which may o...

Atrial fibrillation is a common arrhythmia associated with significant morbidity including angina, heart failure and stroke. Medical therapy remains suboptimal with significant side effects and toxicities, as well as a high recurrence rate. Catheter ablation or modification of the atrio-ventricular node with pacemaker implantation provides rate control but subjects the patient to the risks of a...

Over 100,000 implantable cardiac pacemakers are currently being used to rehabilitate patients with heart block. The chemical batteries powering these pacemakers usually fail within a few years. A variety of nuclear batteries with the potential of providing long-lived (10-20 years) pacemaker power, are under development. This paper reviews the status of this development. Nuclear powered pacemake...

BACKGROUND Since the introduction of the dual chamber pacemaker (DDDR) in the early 1980s, researchers have repeatedly discussed and attempted to optimize the atrioventricular (AV) interval, in order to increase the cardiac performance of pacemaker patients. Nominal AV delay in a DDDR is not, by hemodynamics, the best option for the majority of patients with AV conduction disorders. Our researc...

Abstract Funding Acknowledgements Type of funding sources: Foundation. Main source(s): Karl G. Andersen Foundation Introduction External cardioversion (ECV) with transthoracic shock is a standard procedure to control atrial fibrillation and flutter in patients regardless whether cardiovascular implantable electronic devices (CIED) are situ. Studies have demonstrated infrequent ECV-related CIED ...
