FDA warns of deaths, adverse events with the Lariat device

The FDA issued a safety alert on July 13, warning of deaths and severe adverse events associated with the use of SentreHEART's Lariat suture delivery device for left atrial appendage (LAA) exclusion and preventing strokes in patients with atrial fibrillation.

Study finds 7% malfunction rate in CIEDs attributable to radiotherapy

A retrospective analysis found 7 percent of patients with cardiovascular implantable electronic devices (CIEDs) had a malfunction attributed to radiotherapy. All of the cases occurred during neuron-producing radiotherapy, prompting lead researcher Jonathan D. Grant, MD, to recommend the use of non-neutron-producing radiotherapy when clinically feasible.

Fewer than 10% of Medicare beneficiaries receive an ICD after MI

Fewer than 10 percent of older adults received an implantable cardioverter-defibrillator (ICD) following an MI, according to an analysis of Medicare beneficiaries who had low ejection fraction. Although the patients were at an increased risk of sudden cardiac death, only 8.1 percent were implanted with the device within a year of their MI event.

No anticoagulation bridging for elective procedures offers benefits

Here’s a bridge you may consider burning: anticoagulation bridging therapy for patients with atrial fibrillation who undergo an elective operation. A randomized clinical trial found no bridging after discontinuing warfarin led to no more thromboembolic events than bridging, with a lower risk of bleeding.

Sudden cardiac deaths are rare with pacemakers or ICDs

A prospective analysis found 4.3 percent of sudden cardiac deaths in San Francisco were in patients with pacemakers or implantable cardioverter-defibrillators (ICDs). Half of the deaths were related to the devices, and the most common cause of death was ventricular tachycardia or ventricular fibrillation.

Medtronic acquires CardioInsight and expands its AF business

Medtronic acquired CardioInsight Technologies in a debt-free deal announced on June 19 that increases Medtronic’s focus on atrial fibrillation and other arrhythmias. The deal was valued at approximately $93 million.

Life-threatening arrhythmias are rare when reducing cardiac telemetry

If hospitals and health systems reduce their use of cardiac telemetry in nonintensive care settings, they are unlikely to miss life-threatening arrhythmias, according to a single-center study. Life-threatening arrhythmias occurred in one of 2,645 patients.

Obesity contributes to increased risk of AF across clinical settings

A meta-analysis of 51 studies found that increases in body mass index were associated with a significant risk of atrial fibrillation (AF). The results were consistent across different clinical settings.

Riata, TAVR & legacies

Are Riata concerns a thing of the past and transcatheter aortic valve replacement (TAVR) for almost anyone with severe aortic stenosis the way of the future? Presentations at recent cardiology conferences addressed those questions.

Survival rates increase with more activity in patients with ICDs and CRT devices

Patients with implantable cardioverter-defibrillators (ICDs) or cardiac resynchronization therapy (CRT) devices who were most active had improved health outcomes and were more likely to survive, according to a registry analysis.
