Hazim Rahbi, Mohammed El-Din, Mohammad Salloum, Naeem Shaukat, Mohsin Farooq
BACKGROUND AND PURPOSE: Complex cardiac pacing with either an implantable cardiovertor defibrillator (ICD) or a biventricular pacemaker with pacing only (CRT-P) or biventricular pacemaker with implantable cardiovertor defibrillator (CRT-D) plays an important role in the management of patients with heart failure. However, device implantation is associated with rare but significant complications which may limit the number of centres offering this treatment. The aim of this study is to define procedural success and complication rates associated with implantation of complex implantable cardiac devices in a district general hospital...

BACKGROUND: Left ventricular ejection fraction (LVEF) recovers during follow-up in a significant proportion of patients implanted with a cardioverter defibrillator (ICD) for primary prevention. Little is known about the midterm arrhythmic risk in this population, particularly in relation to the presence or absence of ischemic cardiomyopathy. METHODS AND RESULTS: We retrospectively analyzed 286 patients with an ICD implanted for primary prevention between 2002 and 2010...

We constructed an intracardiac vectorcardiogram from 3 configurations of intracardiac cardiovertor defibrilator (ICD) electrograms (EGMs). Six distinctive 3 lead combinations were selected out of five leads: can to right ventricular coil (RVC); RVC to superior vena cava coil (SVC); atrial lead tip (A-tip) to right ventricular (RV)-ring; can to RV-ring; RV-tip to RVC, in a patient with dual chamber ICD. Surface spatial QRS-T angle (119.8°) was similar to intracardiac spatial QRS-T angle derived from ICD EGMs combination A (101...

Persistent left superior vena cava, usually an incidental finding, is the most common thoracic vein anatomical variation draining into the coronary sinus. Central venous catheter procedures may be complicated secondary to the presence of a persistent left superior vena cava, leading to life-threatening complications such as arrhythmias, cardiogenic shock, and cardiac arrest. We present a case of persistent superior vena cava diagnosed on transthoracic echocardiogram (TTE) in a patient with congestive heart failure...

Sudden cardiac death (SCD) is still a major public health issue with an estimated annual incidence ranging from 184,000 to > 400,000 per year. The ACC/AHA/ESC 2006 guidelines define SCD as "death from an unexpected circulatory arrest, usually due to a cardiac arrhythmia occurring within an hour of the onset of symptoms". A recent study of sudden cardiac death using multiple sources of ascertainment found that coronary artery disease was present in more than 50% of patients older than 35 years who died suddenly and underwent autopsy...

BACKGROUND: Prevention of sudden cardiac death has always been a challenge for electrophysiologists and to date, automatic implantable cardiovertor defibrillator (AICD) is found to be the only remedy. This device delivers an intracardiac shock whenever it senses a fatal ventricular arrhythmia in order to achieve sinus rhythm. If the delivery of these intracardiac shocks becomes frequent, the situation is declared as an electrical storm. This article deals with the frequency, precipitating factors and prevention of electrical storms...

BACKGROUND: With the development of new technical devices and software more appropriate for pediatric patients, pacemaker implantations in children and young adults have increased over time. It is necessary to monitor the mid- and long-term consequences. The decision for the implantation of a cardiovertor defibrillator (ICD) in children remains challenging despite technical improvements. OBJECTIVE: To assess the safety of pacemaker implantation in children, to review old and new indications, and to point out changes of management over time...

Case report and review of literature of a 33-year-old-male patient who was suffering from recurrent events of loss of consciousness (syncope) found to have multiple events of sustained and non sustained left bundle-branch morphology ventricular tachycardia during Holter evaluation. Both, the echocardiographic and magnetic resonance studies demonstrated morphological changes as seen in Arrhythmogenic right ventricular cardiomyopathy. Arrhythmogenic Right Ventricular Dysplasia (ARVD) is a rare cardiomyopathy characterized by life-threatening ventricular arrhythmias in the absence of apparent structural left heart disease, predominantly occurring within the male gender...

BACKGROUND: Surveys of cardiac pacing and implantable cardiovertor defibrillators (ICD) have been reported since 1969 and 1993 respectively. Increasing costs of medical technology, budget constraints and emergent new clinical indications prompted our committee to conduct the first survey of cardiac rhythm management and device implant patterns in Puerto Rico. METHOD: Clinical and demographic data were obtained for all cardiac devices sold and implanted from 2000 to 2006, through a joint agreement with official representatives of the 2 largest manufacturers and distributors of cardiac pacemakers and ICD in Puerto Rico...

BACKGROUND: Electroconvulsive therapy (ECT) can be life-saving in treating depression, even for high-risk cardiac patients. A 56-year-old man with type 2 diabetes and dilated cardiomyopathy, using both a defibrillator and an experimental cardiac contractility modulator, had had episodes of severe depression superimposed on dysthymia for 27 years, with a current exacerbation over the past 2 years, and little response to antidepressant treatment. METHOD: He received a course of 12 ECTs (6 right-unilateral and 6 left-anterior/right-temporal electrode placements)...

PURPOSE OF REVIEW: Pacemaker and implantable cardiovertor defibrillator utilization is evolving rapidly. Expanding indications are reviewed. RECENT FINDINGS: Current pacemakers are smaller, more dependable, longer lasting and have rate-adaptive features. Implantable cardiovertor defibrillators use transvenous leads and have advanced pacing abilities. Primary pacing indications remain sinus node dysfunction or atrioventricular conduction abnormalities. Dual-chamber pacemakers compared with single chamber ventricular pacemakers, have small quality of life advantages and result in less atrial fibrillation, but decrease stroke rates and mortality...

Bundle branch reentrant (BBR) tachycardia is an uncommon form of ventricular tachycardia (VT) incorporating both bundle branches into the reentry circuit. The arrhythmia is usually seen in patients with an acquired heart disease and significant conduction system impairment, although patients with structurally normal heart have been described. Surface ECG in sinus rhythm (SR) characteristically shows intraventricular conduction defects. Patients typically present with presyncope, syncope or sudden death because of VT with fast rates frequently above 200 beats per minute...

Transient or permanent malfunction of implantable device may result from electromagnetic interference during delivery of radiofrequency energy for treatment of cardiac arrhythmias. Therefore, there is a clinical need for an alternative energy source for cardiac arrhythmia ablation in patients with implantable device. This report presents a case of the absence of electromagnetic interference to an implantable cardioverter defibrillator during atrioventricular nodal ablation for atrial fibrillation to avoid inappropriate shock...

We present an evidence-based overview of primary prevention of sudden cardiac death. Several recent studies have provided important data regarding pharmacologic and device-based therapy for patients with conditions that confer high risk for sudden death. A rational approach to these therapies, with emphasis on implanted cardiovertor defibrillators, is discussed.

A case of a patient with sustained ventricular tachycardia (VT) undergoing implantable cardiovertor defibrillator (ICD) implantation, using transesophageal echocardiography (TEE) and near infrared spectroscopy (NIR) is described. A 67-year-old man with sustained VT associated with old myocardial infarction underwent ICD implantation. Anesthesia was induced with fentanyl and propofol and maintained with nitrous oxide, oxygen, sevoflurane, and fentanyl. Global hypokinesis of the left ventricle was observed in the short-axis view provided by TEE...

OBJECTIVE: The clinical features of coronary artery spasm as a cause of cardiac arrest were determined in a prospective study on out-of-hospital cardiac arrest (OHCA). METHODS: Coronary angiography was performed at admission in 300 consecutive patients with no obvious non-cardiac cause of OHCA. In survivors with no or minimal coronary artery stenosis, a second angiography with provocation test and electrophysiological testing were performed at 1 month. RESULTS: Spasm was demonstrated in ten patients...

The destruction of the World Trade Center and associated terrorist activities of September 11, 2001 have spurred interest in understanding the medical consequences of terrorist activity. Currently, there is a paucity of data regarding this subject. Potential effects, however, can be garnered by studying the medical effects of other acute stressors, such as earthquakes, missile attacks, and the like. None of these stressors have been studied extensively, but there is enough data available concerning earthquakes to indicate that in some instances, the effects of the earthquake may last at least a period of weeks, if not months, following the earthquake...

Sub-Saharan Africa is dominated by diseases of poverty. HIV/AIDS affects 28.5 out of a total of 600 million in the region. South Africa is the only country in sub-Saharan Africa in which implantable cardiovertor defibrillators (ICDs) are implanted (0.8/million in 2001). Only 3 of the 35 new ICDs were implanted in state-funded public hospitals. The pacemaker implantation rate for South Africa was 41/million in 2001. Approximately 20% of the population consume 56% of the health care expenditure, mainly funded by Medical Insurance...
