Einstein Health Papers

Background

Percutaneous left atrial appendage occlusion (LAAO) has been rapidly evolving since FDA’s approval in 2015 and has become more of a same-day-discharge procedure. Cancer patient with atrial fibrillation/flutter (AF) population can benefit from the procedure but the in-hospital outcomes and readmission data were rarely studied.

Objectives

We investigated the utilization, in-hospital and readmission outcomes in cancer patients with AF who underwent LAAO.

Methods

Data were derived from the National Inpatient Sample and National Readmissions Database from 2016 to 2019. Patients with primary diagnosis of AF admitted for LAAO (ICD-10 code 02L73DK) were grouped by cancer as a secondary diagnosis. …

Einstein Health Papers

Protein–energy malnutrition (PEM), which leads to a reduced ability of tissues to regenerate and repair themselves, may exacerbate many chronic diseases, including atrial fibrillation (AF), which occurs as a response of the heart to chronic inflammation. However, population-based studies examining the association between PEM and the prevalence and health care burden of AF are lacking. The aim of this retrospective cohort study was to estimate the impact of PEM on the prevalence and clinical outcomes of hospitalization for AF. The National Inpatient Sample (NIS) 2016 and 2017 datasets were searched for data on hospitalized adult patients with AF as a …

A Unique Case Of Atrial Fibrillation Secondary To Squamous Cell Lung Carcinoma, Mohammad J. Malik, Emily K. Wilson, Vijay Bandhakavi

Research Day

Atrial fibrillation (AF) is widely considered to be the most prevalent cardiac arrhythmia with an incidence of roughly 1-2% in the United States alone. The incidence of AF has been known to increase with advancing age and thus presents a significant burden on healthcare systems across the globe. AF arises as a result of several mechanisms including structural changes that occur to the heart overtime. Here we present a case in which a 63-year-old male with no past medical history except heavy tobacco use presented to the emergency department complaining of shortness of breath. He also endorsed having palpitations and …

Department of Medicine Faculty Papers

Direct-acting oral anticoagulants (DOACs) represent the standard for preventing stroke and systemic embolization (SSE) in patients with atrial fibrillation (AF). There is limited information for patients ≥ 80 years. We report a retrospective analysis of AF patients ≥ 80 years prescribed either a US Food and Drug Administration (FDA)-approved reduced (n = 514) or full dose (n = 199) DOAC (Dabigatran, Rivaroxaban, or Apixaban) between January 1st, 2011 (first DOAC commercially available) and May 31st, 2017. The following multivariable differences in baseline characteristics were identified: patients prescribed a reduced dose DOAC were older (p < 0.001), had worse renal function (p = 0.001), were more often prescribed aspirin (p = 0.004) or aspirin and clopidogrel (p < 0.001), and more often had new-onset AF (p = 0.001). SSE and central nervous system (CNS) bleed rates were low and not different (1.02 vs 0 %/yr and 1.45 vs 0.44 %/yr) for the reduced and full dose groups, respectively. For non-CNS bleeds, rates were 10.89 vs 4.15 %/yr (p < 0.001, univariable) for the reduced and full doses, respectively. The mortality rate was 6.24 vs 1.75 %/yr (p = 0.001, univariable) for the reduced and full doses. Unlike the non-CNS bleed rate, mortality rate differences remained significant when adjusted for baseline characteristics. Thus, DOACs in patients ≥ 80 with AF effectively reduce SSE with a low risk of CNS bleeding, independent of DOAC dose. The higher non-CNS bleed rate and not the mortality rate is explained by the higher risk baseline characteristics in the reduced DOAC dose group. Further investigation of the etiology of non-CNS bleeds and mortality is warranted.

The Undesirable Communication: A Case Of Cerebral Air Emboli In The Setting Of Atrio-Esophageal Fistula Following Atrial Fibrillation Catheter Ablation, Momin Islam, Hussam Al Hennawi, Anwar Khedr, Khaled Harmouch, Mohammad F. Mathbout Jul 2022

The Undesirable Communication: A Case Of Cerebral Air Emboli In The Setting Of Atrio-Esophageal Fistula Following Atrial Fibrillation Catheter Ablation, Momin Islam, Hussam Al Hennawi, Anwar Khedr, Khaled Harmouch, Mohammad F. Mathbout

Abington Jefferson Health Papers

Atrial-esophageal fistula is an extremely rare condition but is often a deleterious complication following catheter ablation for atrial fibrillation. The associated iatrogenic communication acts as a conduit for air and bacterial translocation, which may lead to cerebral air embolism and polymicrobial sepsis, respectively. Coupled with a history of invasive procedures, the diagnosis is largely based on the accompanying neurological symptoms. In this report, we present the case of a 73-year-old female who presented with neurological deficits attributed to cerebral vascular emboli three weeks after catheter ablation for the treatment of chronic atrial fibrillation.

Dronedarone For Atrial Fibrillation Prophylaxis In Patients Undergoing Open Heart Surgical Interventions: A Case Series, Jay D. Patel, Mrhaf Alsamman, Dewansh Goel, Sai Gudduru, Rakesh Prashad

Journal of Community Hospital Internal Medicine Perspectives

Atrial fibrillation (a-fib) is one of the most frequently encountered and studied arrhythmias in medicine. The presence of A-fib in the post-operative period of coronary artery bypass graft (CABG) surgery is of particular concern for clinicians as this presents risks of post-operative stroke, hospital readmission, or anticoagulation dilemmas depending on the patient’s comorbidities. In this case study, we present 5 patients who were treated with dronedarone prior to undergoing open heart procedures. We subsequently followed each patients clinical course paying close attention for any evidence of post-operative a-fib.

New Technologies For Detection And Management Of Atrial Fibrillation, Adel K. Hamad Jul 2021

New Technologies For Detection And Management Of Atrial Fibrillation, Adel K. Hamad

Journal of the Saudi Heart Association

Atrial fibrillation (AF) is a common and prevalent form of arrhythmia. It is associated with various morbidities with stroke being the major hazard. Since AF is often reported to be asymptomatic, many individuals remain unaware of their condition and may not receive the requisite treatment. Hence, screening for AF has gained substantial attention recently. Growing advancement in technology has paved way for numerous approaches for AF screening using medical-prescribed devices as well as consumer electronic devices. However, there still lies scope for large-scale randomized trials which would explore additional aspects associated with AF. This review very concisely summarizes AF, screening, …

Hemodynamic Management Of Patients With Ejection Fraction < 50% Undergoing Pulmonary Vein Ablation, Aaron B. Hesselson, Heather Hesselson

Internal Medicine Faculty Publications

There is no consensus regarding optimal methodology forblood pressure monitoring inpatients with a depressed ejection fraction undergoingcatheter ablationfor atrial fibrillation. Our goalswere to determine ifhemodynamicmanagementdifferences exist during radiofrequency ablation for atrial fibrillation in patients with and without an ejection fraction< 50%, and whether management was influenced by the utilization of invasive arterial blood pressure monitoring. This single-center trial retrospectively compared blood pressure management during catheterablation of atrial fibrillationin all patients with an ejection fraction< 50% over a 2-year span (n=44), and compared to an age-matched cohort with preserved ejection fraction ablated over the same span in time (n=44). Blood pressure was not significantly managed differently between the groups, and did not appear to be influenced by the use of invasive arterial blood pressure monitoring. Hemodynamic management is similar across the spectrum of ejection fraction, regardless of invasive arterial blood pressure monitoring, which challenges the need for invasive arterial blood pressure monitoringduringcatheter ablation ofatrial fibrillationin left ventricular systolic dysfunction.

Algorithm For Cavo-Tricuspid Isthmus Flutter On Surface Ecgs: The Actions Study., Daniel Frisch, Eitan Frankel, Deanna Gill, Jad Al Danaf

Division of Cardiology Faculty Papers

OBJECTIVE: Cavo-tricuspid isthmus atrial flutter (CTI-AFL) is an important arrhythmia to recognise because there is a highly effective and relatively low-risk ablation strategy. However, clinical experience has demonstrated that providers often have difficulty distinguishing AFL from atrial fibrillation.

METHODS: We developed a novel ECG-based three-step algorithm to identify CTI-AFL based on established CTI flutter characteristics and verified on consecutive ablation cases of typical flutter, atypical flutter and atrial fibrillation. The algorithm assesses V1/inferior lead F-wave concordance, consistency of P-wave morphology and the presence of isoelectric intervals in the inferior leads. In this observation study, the algorithm was validated on a …
