Introduction: Coronary artery disease (CAD) and peripheral artery disease (PAD) increase the risks of cardiovascular events and death. Digital health technologies are rapidly expanding to improve healthcare quality and access. The Care4Today Connect (C4T CAD-PAD) mobile application is designed to help patients with CAD and/or PAD improve medication adherence, learn about their disease, make lifestyle modifications, and enhance healthcare provider (HCP) connection via an HCP-facing portal.

5-Year Results From the AMPLATZER Amulet Left Atrial Appendage Occluder Randomized Controlled Trial.
J Am Coll Cardiol
November 2024
University Hospital of Bern, Bern, Switzerland.
Background: The Amulet IDE trial (AMPLATZER Amulet Left Atrial Appendage Occluder [LAAO] Investigational Device Exemption [IDE] Trial) evaluated the safety and effectiveness of the Amulet occluder (Abbott) in patients with nonvalvular atrial fibrillation. The Amulet IDE trial is the largest randomized LAAO trial, comparing the Amulet occluder with the Watchman 2.5 device (Boston Scientific).

Section of Cardiovascular Medicine, Yale University, New Haven, Connecticut.
Article Synopsis
- Chronic kidney disease (CKD) and kidney failure with replacement therapy (KFRT) are common in patients with atrial fibrillation (AF), and this study aimed to investigate outcomes after left atrial appendage occlusion (LAAO) procedures in these patients.
- Data from over 59,000 patients indicated that both CKD and KFRT were linked to higher rates of complications during the procedure and increased risk of death and major adverse events within one year.
- However, the study found no significant difference in the rates of stroke over the same period among patients with CKD or KFRT compared to those without.
Association of Physician Certification and Outcomes Among Patients Undergoing Left Atrial Appendage Occlusion.
JACC Cardiovasc Interv
October 2024
Section of Cardiovascular Medicine, Department of Internal Medicine, Yale University School of Medicine, New Haven, CT, USA; Center for Outcomes Research and Evaluation, Yale New Haven Health Services Corporation, New Haven, CT, USA.
Article Synopsis
- The study examines outcomes of percutaneous left atrial appendage occlusion (LAAO) procedures performed by either electrophysiologists (EPs) or interventional cardiologists (ICs) between 2020 and 2022, focusing on patient safety and complications.
- Key findings indicate that EPs utilized intracardiac echocardiography more frequently and achieved lower radiation exposure; however, rates of major adverse events (MAE) and in-hospital mortality were comparable between the two groups.
- Overall, LAAO was deemed safe with no significant differences in outcomes based on operator certification, highlighting the importance of continued use of these techniques by both specialties for broader patient access.
State of the art of mobile health technologies use in clinical arrhythmia care.
Commun Med (Lond)
October 2024
Kansas City Heart Rhythm Institute, Overland Park, KS, USA.
The rapid growth in consumer-facing mobile and sensor technologies has created tremendous opportunities for patient-driven personalized health management. The diagnosis and management of cardiac arrhythmias are particularly well suited to benefit from these easily accessible consumer health technologies. In particular, smartphone-based and wrist-worn wearable electrocardiogram (ECG) and photoplethysmography (PPG) technology can facilitate relatively inexpensive, long-term rhythm monitoring.

Pulmonary Artery Injury Following Endocardial Left Atrial Appendage Occlusion: The Known and Unknown.
JACC Clin Electrophysiol
October 2024
Kansas City Heart Rhythm Institute, Overland Park, Kansas, USA. Electronic address:
Article Synopsis
- Left atrial appendage closure (LAAC) is used as an alternative stroke prevention method for patients who cannot take blood thinners, but pulmonary artery injury (PAI) is a rare and serious complication associated with it.
- A review of previous PAI cases and data from the FDA's MAUDE database identified 36 cases, predominantly involving older patients, and highlighted that PAI often presents soon after the procedure, with a significant percentage requiring surgery.
- The study emphasizes the need for heightened awareness of PAI symptoms post-LAAC, especially concerning rapid fluid accumulation around the heart, even without clear predictive signs from imaging or clinical details.

November 2024
Division of Cardiology, Northwestern University, Feinberg School of Medicine, Chicago, IL (R.S.P.).
Background: Atrial fibrillation (AF) is associated with an increased risk of stroke, yet the limitations of conventional monitoring have restricted our understanding of AF burden risk thresholds. Predictive algorithms incorporating continuous AF burden measures may be useful for predicting stroke. This study evaluated the performance of temporal AF burden trends as predictors of stroke from a large cohort with insertable cardiac monitors.

Background: The use of cardiopulmonary resuscitation (CPR) and automated external defibrillators (AEDs) significantly improve the chances of survival after out-of-hospital cardiac arrest. Subsequently, state laws mandate training in CPR and AED use for high school graduation. However, training and its impact vary and must be better understood.

Division of Cardiology, Cardiac Arrhythmia Service, Loma Linda University Health, 11234 Anderson St, Loma Linda, CA, 92354, USA.
Background: The safety and efficacy of CA for AF and left-sided atrial arrhythmias (AA) in patients with left atrial appendage occlusion (LAAO) devices are lacking.
Methods: This is a single-center retrospective registry that included all patients with prior LAAO who underwent catheter ablation for AF or left-sided atrial arrhythmia from January 2020-January 2023. The primary outcomes were procedure-related complications, device-related complications, AA recurrence, and stroke.

Outcomes of hybrid surgical ablation and concomitant left atrial appendage exclusion in long-standing persistent atrial fibrillation.
J Cardiovasc Electrophysiol
October 2024
Kansas City Heart Rhythm Institute (KCHRI), Overland Park, Kansas, USA.
Article Synopsis
- Management of long-standing persistent atrial fibrillation (LSPAF) is challenging, and hybrid convergent ablation with left atrial appendage (LAA) clipping shows better results compared to traditional endocardial-only procedures.!
- A study of 79 patients demonstrated a 73.8% success rate in maintaining freedom from atrial fibrillation after 12 months, but persistent posterior wall activity was noted in a significant number of cases.!
- The findings suggest that combining hybrid ablation and LAA clipping is effective for long-term AF-free survival in LSPAF patients, though recurrence of AF is associated with persistent activity in the posterior wall of the heart.!
Application repetition and electrode-tissue contact result in deeper lesions using a pulsed-field ablation circular variable loop catheter.
Europace

Department of Cardiology, Montefiore Medical Center, 111 E 210th Street, Bronx, NY 10467, USA.
Article Synopsis
- Pulsed-field ablation (PFA) is a new technique for treating heart arrhythmias that focuses on the heart muscle without using heat. The study aims to determine how repeated applications and the contact force of the catheter affect the creation of lesions in heart tissue.
- Researchers used a circular loop catheter to test these factors on a potato model and a swine heart model, observing that more repetitions and better contact lead to deeper and more effective lesions.
- The results suggest that successful PFA relies on the physics of the procedure rather than just the immediate disappearance of electrical signals, indicating a need for precise application techniques.

A novel scoring system and correlative analysis of the strength and effectiveness of nationwide high school cardiopulmonary resuscitation mandates: Insights from a high school CPR study.
Heart Rhythm
July 2024
Kansas City Heart Rhythm Institute, Overland Park, Kansas. Electronic address:
Article Synopsis
- Multiple states have implemented CPR training for high school students and staff to reduce sudden cardiac death (SCD), but the quality and execution of these mandates differ significantly across the country.
- A scoring system was created to objectively assess CPR training mandates in all 50 states and the District of Columbia, revealing a wide range in scores that indicate the robustness of these mandates.
- The study's findings suggest that although there is variability in state mandates, no strong link was found between CPR training requirements and reduced SCD rates, underscoring the need for more consistent and effective policies.
