BACKGROUND Despite the increasing recognition of thromboembolic complications of the Fontan procedure, data characterizing such events are limited. The total cavopulmonary connection is believed to be less prone to this complication than other modifications of Fontan operations. We examined our experience with thromboembolism after Fontan operations to(More)
BACKGROUND Stroke and systemic thromboembolism are serious problems for patients with atrial fibrillation (AF), but their incidence can be substantially reduced by appropriate anticoagulation. Bleeding is the major complication of anticoagulant treatment, and the relative risks for bleeding vs stroke must be considered when starting anticoagulation. (More)
AIMS Implantable cardiac defibrillator (ICD) implantation is a class IIA recommendation for patients with cardiac sarcoidosis (CS). However, little is known about the efficacy and safety of ICDs in this population. The goal of this multicentre retrospective data review was to evaluate the efficacy and safety of ICDs in patients with CS. METHODS AND(More)
BACKGROUND While previous studies using epidemiological data and ambulatory ECG monitoring have shown peak occurrence of sudden death and nonsustained ventricular tachycardia in the morning, none have examined circadian variation of potentially life-threatening ventricular tachycardia (VT), nor has any study observed circadian behavior of any arrhythmias in(More)
As the use of ICDs increases, more young patients will be eligible to receive these devices. Such patients may have different concerns than older patients who more commonly receive ICDs. We investigated quality-of-life issues in patients followed by the Yale electrophysiology service who were < or = 40 years old (mean = 28) at the time of ICD implant. Mean(More)
Before 1950, there was no clear perception of the interrelationship of serum lipids, atherosclerosis, and coronary heart disease. Since then, research laboratories have made conflicting claims for the most useful measurement of the serum lipid levels in detecting and managing coronary heart disease. Emphasis has been placed in turn on the measurement of(More)
Groups of St Peter's fish Sarotherodon galilaeus were trained during 28 days of classical conditioning to respond to an acoustic signal by approaching a feeder. Their ability to retain the acoustically conditioned behaviour was tested after eight different intervals ranging from 12 to 188 days from termination of training. Retention tests comprised 7(More)
UNLABELLED Previous studies have indicated that many anesthesiologists exhibit symptoms of chronic stress. There is a paucity of data, however, regarding the existence of acute stress signs among anesthesiologists. Anesthesiologists from three practice settings (n = 38) were studied while they were anesthetizing 203 patients. Heart rate (HR) was recorded(More)
