Po-03-050 incidence of inappropriate atrial fibrillation detection with remote cardiac monitoring by insertable cardiac monitor
An increasing number of patients are receiving long-term cardiac monitoring to detect and manage atrial fibrillation (AF). The Reveal LINQ insertable cardiac monitor (ICM) (Medtronic, Minneapolis, MN, U.S.A.), is a miniaturized, leadless, subcutaneous, long-term cardiac monitoring that is widely used to manage arrhythmias.

Po-711-01 catheter ablation of the mitral isthmus line using the novel diamondtemp ablation system: first experience using two different ablation protocols
Mitral ishmus ablation is an established approach to treat perimitral reentrant tachycardia, and often performed as substrat modification in patients with persistent atrial fibrillation (AF). Bidirectional block of the mitral isthmus line (MIL) is still a challenge using conventional ablation catheters, but is essential to prevent arrhythmia recurrence. Recently, the novel DiamondTempTM (DT) ablation system (Medtronic ®, Inc., Minneapolis, Minnesota) was introduced and allows for high-power, short-duration ablation in a temperature-controlled mode.

Association of Echocardiographic Measures of Left Atrial Function and Size With Incident Dementia
CONCLUSIONS AND RELEVANCE: In this exploratory analysis of a US community-based cohort, several echocardiographic measures of lower LA function were significantly associated with an increased risk of subsequent dementia. Measures of LA size were not significantly associated with dementia risk. These findings suggest that impaired LA function may be a risk factor associated with dementia.PMID:35315884 | DOI:10.1001/jama.2022.2518

What does LBBB look like in severe hypothermia? Is there a long QT? Is the QT appropriate for the temperature?
This patient was found down in a Minneapolis winter.  He was very cold with frostbitten fingers and toes.  He was alert but encephalopathic and delirious and very agitated and could not be adequately calmed with olanzapine and lorazepam, so we intubated him.  The first reliable temperature could only be obtained with a Foley thermistor, and it was 26.5 degrees C (79.7 F).His BP was 76/60.  K was 2.8 mEq/L.Here was his first ECG:There is sinus bradycardia with left bundle branch block (LBBB), with proportional ST-T, and VERY long QT and a PVC.  I measure the QT at 800 ms. Notice that there are ...

Electrophysiological ventricular substrate of stroke: a prospective cohort study in the Atherosclerosis Risk in Communities (ARIC) study
Conclusions PVC burden (reflected by cardiac memory) is associated with ischaemic stroke. Transient cardiac memory (likely through TD-IBBB) precedes ICH.

Meta-Analysis Comparing Antiplatelet Therapy Versus Direct Oral Anticoagulation in Percutaneous Left Atrial Appendage Closure
Percutaneous left atrial appendage closure (LAAC) is currently an alternative treatment in patients with nonvalvular atrial fibrillation who are not candidates for long-term oral anticoagulation.1 The typical devices used are either a Watchman (Boston Scientific, Marlborough, MA), Amplatzer Cardiac Plug (St. Jude Medical, Minneapolis, MN), or Amplatzer Amulet (St. Jude Medical, Minneapolis, MN). The rate of device-related thrombus (DRT) has a reported onset of 30 to 90 days after the procedure. Therefore, medical management is warranted to decrease the risk and direct oral anticoagulation medications (DOACs) are typically used.

Implantation of leadless pacing systems in patients early after tricuspid valve surgery: A feasible option
ConclusionsImplantation of an LPM early after TV surgery is a feasible option. LPM implantation does not affect TV or bioprosthesis performance in transthoracic echocardiography.

Leadless pacemaker for patients following cardiac valve intervention.
CONCLUSION: A leadless pacemaker is safe and efficient after valve intervention, and therefore represents an effective pacing option in patients after valve intervention. PMID: 32891563 [PubMed - as supplied by publisher]

Junkosha & #039;s Latest Innovation Makes Way for Next-Gen Catheters
A new catheter solution from Junkosha represents a major step toward smaller, more flexible, and higher data capacity catheters, according to the Japanese wire and cable supplier. Tokyo-based Junkosha launched its new Multi-Filar active catheter solution at the recent MD&M Minneapolis expo. The new cables have a capacity of up to 60 power lines depending on AWG size or pitch, and are designed to provide not only increased functionality but also more signals into formerly inaccessible areas of the body, the company said. Using Junkosha’s precision-engineered PTFE lamination tech...

Detection of atrial fibrillation using an implantable loop recorder following cryptogenic stroke: implications for post-stroke electrocardiographic monitoring
ConclusionThe likelihood of AF detection by an ILR in the first month post-CS is low. Thus, the diagnostic yield of 30  days of AECG monitoring is likely to be limited. These data suggest a rationale for proceeding directly to ILR implantation prior to hospital discharge in CS patients, as many have AF detected during longer follow-up.

Empowering Patients to Take Care of Their Hearts
Hypertension affects about 103 million Americans, according to the American Heart Association (AHA). Atrial fibrillation (AFib), which is often associated with hypertension and could affect up to 6 million people per CDC statistics, can be asymptomatic, so patients may be unaware they have it. The CDC also reports that more than 600,000 Americans die each year from heart disease, and coronary artery disease is the most common type of such disease. Also impacting the heart is diabetes—and more than 100 million Americans suffer from it, the CDC reported. “Heart dise...

Left Atrial Occlusion Device Implantation: the Role of the Echocardiographer
AbstractPurpose of ReviewAtrial fibrillation is the most common arrhythmia worldwide and is a major risk factor for embolic stroke. For patients with atrial fibrillation who are unable to tolerate systemic anticoagulation, left atrial appendage (LAA) occlusion has been shown to mitigate stroke risk. In this article, we describe the vital role of the echocardiographer in intraprocedural guidance of percutaneous LAA occlusion procedures as well as in the pre- and post-procedure assessment of these patients.Recent FindingsA few percutaneously delivered devices for LAA exclusion from the systemic circulation are available in c...
