The conduction system of the heart initiates and coordinates the electric signal that causes the rhythmic and synchronized contractions of the atria and ventricles. In higher vertebrates, this system comprises the sinuatrial (SAN) and atrioventricular nodes (AVN) and the “wiring” of the ventricles. The latter comprises the atrioventricular bundle (AVB), the left and right bundle branches (BBs),...

Introduction In this case report, we present an unusual and potentially lifethreatening complication of cardiac electronic device lead extraction during which a peripherally inserted central venous catheter (CVC) coursing ipsilaterally to the pacemaker leads was fractured with the use of mechanical extraction tools. Subsequently, a fragment of this catheter embolized distally into the right atr...

Figure 2 Also from the initial interrogation of device. Note the date of SureScan on and off, 16-Jan-1996 (underlined in red), and the evidence of pacer dependence, with 499.9% ventricular pacing. Introduction Patients with cardiac implantable electronic devices were historically unable to undergo magnetic resonance imaging (MRI). In 2011 the Food and Drug Administration approved the first MRI ...

The Surgical Research Laboratory at Sinai Hospital of Detroit has as its primary goal the development of mechanical and biological technics for augmenting or replacing the function of a damaged heart. Scientific contributions from our group include the development of a cardiac pacemaker, a method for electronic control of bladder evacuation, technics for chronic stimulation of nerves, and a met...

Damage to the coronary arteries and related structures from pacemaker and implantable cardioverter-defibrillator lead implantation is a rarely reported complication that can lead to myocardial infarction and pericardial tamponade that may occur acutely or even years later. We summarize the reported cases of injury to coronary arteries and related structures and review the causes of troponin ele...
