CHADS-VASc Score as a Predictor of New-Onset Atrial Fibrillation After Catheter Ablation of Typical Atrial Flutter.

Front Physiol 2020 10;11:558. Epub 2020 Jun 10.

Department of Cardiology, The First Affiliated Hospital of Dalian Medical University, Dalian, China.

Purpose: Cavotricuspid isthmus (CTI) ablation is an effective procedure for typical atrial flutter (AFL), but patients remain at an elevated risk for developing new atrial fibrillation (AF). Currently, there are limited data on the utility of CHADS-VASc score to predict new-onset AF after typical AFL ablation. In this study, we assessed whether the CHADS-VASc score is a useful predictor of new-onset AF after CTI ablation in typical AFL patients without a prior history of AF. Read More

Epicardial bridge via the coronary sinus musculatures revealed by ultra-high-definition mapping.

J Electrocardiol 2020 Apr 24;61:106-111. Epub 2020 Apr 24.

Department of Cardiac Electrophysiology, University of Iowa, IA, USA.

Mapping and ablation of perimitral flutter, a macro-reentrant tachycardia, can be sometimes challenging. We describe a case of perimitral atrial flutter following the pulmonary vein isolation in which mitral isthmus ablation failed to terminate the arrhythmia due to epicardial-endocardial breakthrough via the muscle fibers of coronary sinus. Ultra-high-definition mapping system was utilized to locate the epicardial bridge, and spot ablation of the lesion subsequently terminated the arrhythmia. Read More

Electrophysiologic evidence of epicardial connections between low right atrium and remote right atrial region or coronary sinus musculature: relevance for catheter ablation of typical atrial flutter.

J Cardiovasc Electrophysiol 2020 Jun 20. Epub 2020 Jun 20.

Department of cardiology, Rouen University Hospital, Rouen, France.

Background: The coronary sinus (CS) is surrounded by a myocardial coat with extensive connections to the left and right atria that contributes to interatrial electrical connection. Whereas epicardial connections between CS musculature and the left atrium have largely been demonstrated, clinically relevant epicardial connections from the CS musculature toward the low right atrium (LRA) and epicardial connections between two regions of the right atrium remain questionable.

Methods: Five patients underwent electrophysiology (EP) study for typical atrial flutter (AFl) using either conventional multipolar catheters (4 patients) or 3D high-density mapping system (1 patient). Read More

Electrophysiological significance of the interatrial conduction including cavo-tricuspid isthmus during atrial fibrillation.

J Physiol 2020 Jun 4. Epub 2020 Jun 4.

Yonsei University Health System, Seoul, Republic of Korea.

Key Points: The interatrial conduction, including Bachmann's bundle, the posterior septal conduction, the anterior septal conduction, and the cavo-tricuspid isthmus, contributes to the maintenance mechanisms of atrial fibrillation in a 3D biatrial model. The interatrial conduction ablation including a cavo-tricuspid isthmus ablation significantly affects the wave dynamics of atrial fibrillation (AF) and facilitates the AF termination or atrial tachycardia conversion of the AF after the circumferential pulmonary vein isolation. Additional cavo-tricuspid isthmus ablation after the circumferential pulmonary vein isolation improves long-term rhythm outcome after clinical AF catheter ablation. Read More

Utility of Contact Impedance Mapping in Differentiating the Mechanism of Focal Atrial Tachycardia.

J Innov Card Rhythm Manag 2019 May 15;10(5):3642-3650. Epub 2019 May 15.

Section of Electrophysiology, Division of Cardiovascular Disease, The Institute for Heart and Vascular Health, Einstein Medical Center, Philadelphia, PA, USA.

Contact impedance mapping can differentiate focal atrial tachyarrhythmias from macroreentry (atrial flutter) and localized reentry (atrioventricular nodal reentry tachycardia) by detecting different patterns of regional unipolar tissue impedance distribution. Specifically, focal atrial tachycardia (AT) is characterized by the finding of a contiguous low-impedance area (CLIA) adjacent to the site of origin, surrounded by normal tissue impedance levels. However, it remains unclear whether or not this finding could distinguish different mechanisms of focal AT. Read More

Here, we diagnosed a right coronary artery-right atrium fistula with giant coronary artery aneurysm (CAA) via fetal echocardiography at 35 weeks' gestation. An urgent caesarean delivery was performed at 36 weeks' gestation because CAA caused mitral obstruction, and fetal atrial flutter was present. Read More

Concomitant use of direct oral anticoagulants and aspirin versus direct oral anticoagulants alone in atrial fibrillation and flutter: a retrospective cohort.

BMC Cardiovasc Disord 2020 Jun 1;20(1):263. Epub 2020 Jun 1.

General Internal Medicine Division, Beaumont Health, Royal Oak, MI, USA.

Background: The benefit of combining aspirin and direct oral anticoagulants on the reduction of cardiovascular events in atrial fibrillation or flutter is not well studied. We aimed to assess whether concurrent aspirin and direct oral anticoagulant therapy for atrial fibrillation or flutter will result in less coronary, cerebrovascular and systemic ischemic events compared to direct oral anticoagulant therapy alone.

Methods: Retrospective study of adult patients between 18 and 100 years old who have nonvalvular atrial fibrillation or flutter and were started on a direct oral anticoagulant (apixaban, rivaroxaban, or dabigatran), between January 1, 2010 and September 1, 2015 within the Beaumont Health System.

Evaluating Effectiveness and Safety in Chronic Kidney Disease with Atrial Flutter Using an Anticoagulation Strategy.

Medicina (Kaunas) 2020 May 28;56(6). Epub 2020 May 28.

Division of Gastroenterology, Department of Internal Medicine, Taitung MacKay Memorial Hospital, Taitung 95054, Taiwan.

Recent randomized trials of oral antithrombotic drugs with atrial flutter (AFL) excluded patients with renal impairment because of their increased risk of bleeding. To date, no relevant studies have assessed the effectiveness and safety of different antithrombotic drugs in chronic kidney disease (CKD) patients with AFL. This cohort study evaluated the effectiveness and safety of different antithrombotic drugs in CKD patients with AFL. Read More

Long-term results of irrigated bipolar radiofrequency ablation in patients with recurrent arrhythmia after failed unipolar ablation.

Medicine (Baltimore) 2020 May;99(21):e19970

Department of Cardiology, Poznań University of Medical Sciences.

Introduction: The RF ablation of ventricular tachycardia (VT) or atrial flutter (AFl) can be unsuccessful due to lack of lesion transmurality. Bipolar ablation (BA) is more successful than unipolar ablation (UA). The purpose of our study was to investigate the long-term effect of BA ablation in patients after failed UA. Read More

This report discusses the mapping of an incomplete cavotricuspid isthmus flutter line with a high-density mapping catheter to visualize the arrhythmogenic substrate responsible for incomplete block. The relevant signals were unapparent when using a traditional ablation catheter but were evident with application of a high-density mapping catheter. High-density mapping holds promise for recording electrograms in gaps in other ablation lesion sets that may not be able to be easily identified using more traditional equipment alone. Read More

Revisiting an Underrecognized Strategy for Rhythm Management: Hybrid Therapy for Patients who Convert from Atrial Fibrillation to Flutter on Antiarrhythmic Drugs.

J Innov Card Rhythm Manag 2019 Oct 15;10(10):3842-3847. Epub 2019 Oct 15.

Division of Cardiovascular Medicine, University Hospitals Cleveland Medical Center, Cleveland, OH, USA.

Atrial fibrillation (AF) is often treated with antiarrhythmic drugs (AADs) or catheter ablation. In a unique subset of patients, AF can convert to atrial flutter (AFL) after the initiation of an AAD. It has previously been shown that, in this subset of patients, cavotricuspid isthmus (CTI) ablation followed by the continuation of the AAD regimen has an unusually high rate of successfully maintaining sinus rhythm.
