Electrophysiology & Arrhythmia

 - deal

Abbott will buy two companies that develop electrophysiology products in a move designed to make Abbott a player in the catheter-based electrophysiology market. It also named a chief to lead the business.

 - TactiCath

The FDA approved St. Jude Medical’s contact-force ablation catheter for treating patients with atrial fibrillation.

 - electrophysiology, ICD, pacemaker

Some patients treated with cardiac resynchronization therapy-defibrillators (CRT-Ds) may qualify for pacemaker mode. After long-term improvements were seen with some patients, researchers posited that when left ventricular ejection fraction (LVEF) normalizes and it’s time to change the batteries, it may also be time to flip the switch from D to P.

 - heart_drawing

When comparing risk of inappropriate implantable cardioverter-defibrillator (ICD) shocks in two types of therapy, researchers in the OPTION study found a significant advantage in dual-chamber therapy. Fewer inappropriate shocks were delivered to patients on dual-chamber than on single-chamber settings, especially those programmed with algorithms for minimizing ventricular pacing.

 - anticoagulants

The beauty of novel oral anticoagulants is that they come in fixed doses and don’t require monitoring, as warfarin does. Still, some circumstances warrant an assay, and clinicians should be aware of the potential pitfalls.

Afib patients living longer with ablation-maintained sinus rhythm

Can a little heat really mend a broken heart? Patients with atrial fibrillation were found to have a better mortality rate when sinus rhythm was maintained through radiofrequency ablation (RFA) according to a study published in the September issue of Heart Rhythm.

Get With The Guidelines' newest kid on the block: Afib

The American Heart Association has made improvements to guideline adherence in the treatment of atrial fibrillation a priority, according to a paper published Sept. 2 in Circulation: Cardiovascular Quality and Outcomes.

Force-sensing SMART-AF proves safe and effective

A force-sensing ablation treatment for paroxysmal atrial fibrillation (PAF) helped to improve outcomes in the SMART-AF study, according to results published Aug. 19 in the Journal of the American College of Cardiology. But an accompanying editorial raised questions.

Heart flutter in surgery presages stroke risk

Can atrial fibrillation (AF) or flutter during surgery predict stroke? Research published in the Aug. 13 issue of JAMA appears to confirm that it does.

Is digoxin safe for use in atrial fibrillation? Maybe not

Digoxin, for its wide use and history, may not be as safe for use in atrial fibrillation patients as it is assumed to be. Or is it? A study published Aug. 19 in the Journal of the American College of Cardiology attempted to answer this question.

RF ablation to dominate market growth into 2020

The ablation market is expected to top $10 billion by 2020, according to Transparency Market Research, with radiofrequency ablation leading the charge.

Advancing on ADVANCE III: ICD interval affects hospitalizations, costs

A programming strategy for implantable cardioverter-defibrillators (ICDs) reduced hospitalizations, length of stay and costs compared with standard care, according to a research letter published in the Aug. 6 issue of JAMA.

Complications increase risk for ICD infections

With surgery and introduction of a foreign object into a patient always comes some risk of infection. However, according to a study published online July 31 in Circulation, reducing that risk may involve more than just a clean site.

Older patients with severe dementia 2.9 times more likely to receive pacemaker

A team of researchers reviewing decisions to implant cardiac devices found that older patients with cognitive impairment were more often implanted with pacemakers, according to a study published online July 28 in JAMA Internal Medicine.

Many patients unaware of options, risks with ICD replacement

More than half of patients due for replacement of their implantable cardioverter-defibrillator (ICD) generator did not realize they could opt out and many underestimated the risks of ICD replacement, according to a research letter published online July 28 in JAMA Internal Medicine.

Meta-analysis finds sex differences in acute MI hard to track

We haven’t always spoken the same language in acute MI studies, researchers found when trying evaluate differences and changes to mortality in male and female patients using 46 years of data. The meta-analysis published online July 22 in Circulation found that study differences made comparisons difficult.

Perspective on Pradaxa

Much of the information published this week in BMJ about the oral anticoagulant dabigatran has appeared piecemeal throughout the years. But putting individual events into a narrative paints a more comprehensive picture.

Score predicts patients at risk of ICD testing glitch

Researchers developed and validated a simple risk model that identifies implantable cardioverter-defibrillator (ICDs) patients at risk of an inadequate defibrillation safety margin during defibrillation testing. By predicting who is at risk, physicians may be able to avoid related complications and better manage patients.

Heart-breaking benders: Liquor, wine, binge drinking may raise risk of AF

Jack, Jim and Jose may be doing more than hurting heads; they may be breaking hearts. According to a study published July 22 in the Journal of the American College of Cardiology, what people drink is as important as how much and how often they drink in developing atrial fibrillation (AF).

1 in 38 ICD patients experience major complications to lead revisions

Surgery to revise implantable cardioverter-defibrillator (ICD) leads had the highest overall incidence of major complications compared to initial implantation or procedures that did not involve the leads.

Pacemaker coders: Mind you Ps, Qs and KXs

The Centers for Medicare & Medicaid Services (CMS) initiated a national determination coverage decision July 7 for permanent cardiac pacemakers that will require a modifier to receive Medicare reimbursement for procedures.

Dabigatran on par with warfarin for in-hospital mortality

In-hospital mortality for patients with atrial fibrillation who experienced intracranial bleeding was similar whether they were treated with dabigatran or warfarin in a study published online July 3 in Stroke. The findings may help physicians and patients who are choosing between the two types of anticoagulants.

Device monitoring allows more defined AF classifications

Using data derived from patient monitoring devices, researchers found clearer, more reproducible results on burden and persistence in atrial fibrillation (AF) patients than through clinical observations alone.

It’s not personal: Genotyping may add no value for warfarin dosing

Personalized medicine may not be best means of guiding warfarin therapy, a study published online June 16 in JAMA suggests. In an analysis of outcomes of nine studies across the U.S., Europe and Israel, no benefit to utilizing genetic testing for markers CYP2C9, VKORC1, and CYP4F2 vs.  standard algorithms for dosing were seen.
