The lead failure rate was about 14% overall in a registry of young people with ICDs; the slim Fidelis made up more than two-thirds of their failed leads. There are special considerations when selecting ICD leads for this age group.
The controversy continues over the cardiovascular side effects of both long-acting beta-agonist and long-acting anticholinergic drugs when newly prescribed for the management of chronic obstructive pulmonary disease.
New data from real-life experience of dabigatran for stroke prevention in AF shows that it is often used outside prescribing recommendations, and the risk of both thromboembolism and bleeding may be raised in patients switched from warfarin.
Applying only to primary-prevention patients with no pacing indications, an analysis suggests that more expensive dual-chamber implantable defibrillators, compared with single-chamber devices, pose a higher complication risk without any clinical advantage; yet they seem to be the ICD of choice for such patients, at least in the US.
When they saw reports documenting shortfalls in their programming of ICDs to guidelines, clinicians cleaned up their act and shock rates safely fell; but this kind of teaching might not accomplish enough, researchers say.
The Watchman left-atrial appendage occluder had previously been found noninferior to warfarin in patients with nonvalvular atrial fibrillation; now, with an average of 45 months of follow-up, it's not only noninferior, it's superior, by some statistical measures.
The FDA forbids the use of investigational transcatheter aortic-valve devices in live-case presentations being broadcast from US centers. A new study is offering some much-needed data into whether the agency's concerns are justified.
UPDATED // Guidelines recommend that patients at high risk for thromboembolic events be bridged with heparin therapy, but few randomized trials have compared this strategy with simply maintaining patients on warfarin for their procedures.
N-3 fatty-acid supplementation had no effect on the study's primary end point in this group of patients with multiple cardiovascular risk factors or atherosclerotic disease, but no previous MI. Researchers also saw no effects on the rate of death from coronary causes or sudden death from cardiac causes or major ventricular arrhythmias.
Speaking at the 2013 AATS meeting, Cheney describes his LVAD procedure the toughest of all his heart surgeries, while his transplant was a walk in the park. He and his cardiologist, Dr Jonathan Reiner, are coauthoring a book about Cheney's four-decade-long CVD odyssey.
The trial "confirms and reinforces" conclusions from last year's MADIT-RIT trial, that ICD programming that delays arrhythmia detection can prevent some inappropriate shocks and other unnecessary device treatments but extends the finding to patients with almost any kind of ICD.
It used to be easier deciding which oral anticoagulant to use in patients with nonvalvular atrial fibrillation. With all the choices now available, a new document sorts out their differences and can guide their use in various clinical settings.
A nationwide cohort study in Denmark helps to soften the message from a 2012 study linking the antibiotic to an increased risk of cardiovascular death in the elderly, likely from ventricular arrhythmias, according to researchers; the hazard doesn't seem to apply to younger people in the general population.
