Length of stay and cost of care associated with admissions for atrial fibrillation among patients with cancer.

BMC Cardiovasc Disord 2022 Jun 17;22(1):272. Epub 2022 Jun 17.

Section of Cardiac Electrophysiology, Division of Cardiovascular Medicine, Perelman School of Medicine, University of Pennsylvania, Philadelphia, PA, USA.

Background: The aim of this study is to assess the burden of AF-related hospitalizations inclusive of inflation-adjusted cost-of-care and length-of-stay (LOS) among cancer patients and the impact of direct current cardioversion (DCCV) on these outcomes.

Methods: Using the National Inpatient Sample (NIS), patients hospitalized with either a primary or secondary diagnosis of AF and comorbid cancer were identified and both cost of hospitalization and LOS were evaluated for each group. Subgroup analyses were performed for specific cancer types (breast, lung, colon, prostate and lymphoma), and those receiving DCCV. Read More

Displaced AICD Lead Presenting as Hiccups: A Rare Complication.

J Investig Med High Impact Case Rep 2022 Jan-Dec;10:23247096221103380

State University of New York Upstate Medical University, Syracuse, USA.

Ventricular fibrillation can lead to sudden cardiac death. Automatic implantable cardioverter defibrillator (AICD) devices have shown to be highly successful in the termination of these arrhythmias and are a first-line modality of treatment for the prevention of sudden cardiac death. We present the case of a 69-year-old female with a history of paroxysmal atrial fibrillation on anticoagulation with apixaban and rate controlled with metoprolol who presented from home with a chief complaint of hiccups.

Cardioversion of Post-Ablation Atrial Tachyarrhythmia with Ibutilide and Amiodarone: A Registry-Based Cohort Study.

Int J Environ Res Public Health 2022 May 28;19(11). Epub 2022 May 28.

Medical University of Vienna, Department of Emergency Medicine, Waehringer Guertel 18-20, 1090 Vienna, Austria.

Patients with recurrence of atrial tachyarrhythmia after catheter ablation for atrial fibrillation or atrial flutter constitute a rapidly growing cohort, but study-driven treatment recommendations are lacking. The present study aimed to compare the cardioversion success of ibutilide and amiodarone in patients with post-ablation atrial tachyarrhythmia. We included all episodes of post-ablation atrial tachyarrhythmia in patients treated with either intravenous ibutilide or amiodarone at an academic emergency department from 2010 to 2018. Read More

Terminating spiral waves with a single designed stimulus: Teleportation as the mechanism for defibrillation.

Proc Natl Acad Sci U S A 2022 Jun 9;119(24):e2117568119. Epub 2022 Jun 9.

School of Physics, Georgia Institute of Technology, Atlanta, GA 30332.

We identify and demonstrate a universal mechanism for terminating spiral waves in excitable media using an established topological framework. This mechanism dictates whether high- or low-energy defibrillation shocks succeed or fail. Furthermore, this mechanism allows for the design of a single minimal stimulus capable of defibrillating, at any time, turbulent states driven by multiple spiral waves. Read More

A Systematic Review and Single-center Experience of Azygos Vein Defibrillator Lead Insertion.

J Innov Card Rhythm Manag 2022 May 15;13(5):4987-4993. Epub 2022 May 15.

Department of Internal Medicine, University of Iowa Health Care, Carver College of Medicine, Iowa City, IA, USA.

Defibrillation threshold (DFT) testing is performed in individuals with higher predicted risks of defibrillation failure. Many strategies have been explored to overcome the challenge of high DFT, including an insertion of a defibrillator lead into the azygos vein. We performed a systematic review of the literature to evaluate the safety and efficacy of azygos vein implantable cardioverter-defibrillator insertion for high DFT combined with the analysis of a single-center experience of the procedure at our institution.

Frequency of cardioversions as an additional risk factor for stroke in atrial fibrillation - the FinCV-4 study.

Ann Med 2022 12;54(1):1452-1458

Heart Center, Turku University Hospital and University of Turku, Turku, Finland.

Background: Patients with atrial fibrillation (AF) are selected for oral anticoagulation based on individual patient characteristics. There is little information on how clinical AF burden associates with the risk of ischaemic stroke or systemic embolism (SSE). The aim of this study was to explore the association of the frequency of cardioversions (CV) as a measure of clinical AF burden on the long-term SSE risk, with a focus on patients at intermediate stroke risk based on CHADS-VASc score.

Pharmacological Cardioversion in Patients with Recent-Onset Atrial Fibrillation and Chronic Kidney Disease Subanalysis of the CANT II Study.

Int J Environ Res Public Health 2022 04 17;19(8). Epub 2022 Apr 17.

Department of Cardiology and Interventional Angiology, Kashubian Center for Heart and Vascular Diseases, Pomeranian Hospitals, 84-200 Wejherowo, Poland.

Pharmacological cardioversion (PCV) is commonly a primary option for termination of recent-onset atrial fibrillation (AF) in emergency departments (ED). This is a subanalysis of the CANT II study, evaluating the effectiveness and safety of antazoline in patients ( = 777) at three stages of chronic kidney disease (CKD): Group I > 60 mL/min ( = 531), Group II 45-59 mL/min ( = 149), and Group III < 45 mL/min ( = 97). Patients in Group III were older and with a higher prevalence of co-morbidities; however, we did not find statistically significant differences in the overall effectiveness of PCV in comparison with the other groups.

Influence of advanced life support response time on out-of-hospital cardiac arrest patient outcomes in Taipei.

PLoS One 2022 14;17(4):e0266969. Epub 2022 Apr 14.

Department of Emergency Medicine, Far Eastern Memorial Hospital, New Taipei City, Taiwan.

Background: The association between out-of-hospital cardiac arrest patient survival and advanced life support response time remained controversial. We aimed to test the hypothesis that for adult, non-traumatic, out-of-hospital cardiac arrest patients, a shorter advanced life support response time is associated with a better chance of survival. We analyzed Utstein-based registry data on adult, non-traumatic, out-of-hospital cardiac arrest patients in Taipei from 2011 to 2015. Read More

A review of progress and an advanced method for shock advice algorithms in automated external defibrillators.

Biomed Eng Online 2022 Apr 2;21(1):22. Epub 2022 Apr 2.

Posts and Telecommunications Institute of Technology, Hanoi, Vietnam.

Shock advice algorithm plays a vital role in the detection of sudden cardiac arrests on electrocardiogram signals and hence, brings about survival improvement by delivering prompt defibrillation. The last decade has witnessed a surge of research efforts in racing for efficient shock advice algorithms, in this context. On one hand, it has been reported that the classification performance of traditional threshold-based methods has not complied with the American Heart Association recommendations. Read More
