PO-05-111 CLINICAL OUTCOMES OF CATHETER ABLATION FOR ATRIAL FIBRILLATION, ATRIAL FLUTTER, AND ATRIAL TACHYCARDIA IN WILD-TYPE TRANSTHYRETIN AMYLOID CARDIOMYOPATHY: A PROPOSED TREATMENT STRATEGY FOR CATHETER ABLATION IN EACH ARRHYTHMIA

HeartRhythm

Wild-type transthyretin amyloid cardiomyopathy (ATTRwt-CM) is often accompanied by atrial fibrillation (AF), atrial flutter (AFL), and atrial tachycardia (AT), which are difficult to control because beta-blockers and antiarrhythmic drugs can worsen heart failure (HF).

Atrial dilatation in Atrial fibrillation : A query with multiple twists!

Dr. S. Venkatesan MD

When atrial fibrillation (AF) begins, it can start with a single focus, degenerating to multiple wavelets, and it spreads throughout the entire surface area of both atria. A fibrillatory wave that occurs at a rate of more than 600 beats per minute can cause fatigue in the long run, leading to atrial dilation.

ATTR-ACT Post Hoc Analysis: AFib/AFL Not Predictive of Mortality in Patients With ATTR-CM

American College of Cardiology

Although atrial fibrillation/atrial flutter (AFib/AFL) are common manifestations of transthyretin amyloid cardiomyopathy (ATTR-CM), a post hoc analysis of the ATTR-ACT study, published April 30 in JACC: CardioOncology, found they do not predict all-cause mortality.

Wide Complex Tachycardia -- VT, SVT, or A Fib with RVR? If SVT, is it AVNRT or AVRT?

Dr. Smith's ECG Blog

male with pertinent past medical history including Atrial fibrillation, atrial flutter, cardiomyopathy, Pulmonary Embolism, and hypertension presented to the Emergency Department via ambulance for respiratory distress and tachycardia. Of course, this is NOT atrial fib, but rather PSVT, and so adenosine should work.

Case Report: Multiple types of arrhythmias in a late-confirmed Danon disease

Frontiers in Cardiovascular Medicine

Introduction Danon disease is an X-linked disorder caused by pathogenic variants in lysosome-associated membrane protein 2 ( LAMP2 ) gene, typically characterized by the triad of hypertrophic cardiomyopathy, myopathy, and intellectual disability. However, many patients may not present the typical presentation, especially in the early stage.

Wide-complex tachycardia that didn’t follow the rules

Dr. Smith's ECG Blog

They had a history of non-ischemic cardiomyopathy (EF 30%), as well as PCI with one stent. The WCT is interrupted by a series of variable-morphology QRS complexes, with atrial flutter waves note in II, III, and aVF. The subsequent EP study could not induce VT, only atrial fibrillation.

A fascinating electrophysiology case. What is this wide complex tachycardia, and how best to manage it?

Dr. Smith's ECG Blog

She also has a hx of paroxysmal atrial fibrillation and is on oral anticoagulant treatment. The ECG was interpreted as showing atrial flutter with 2:1 conduction. The heart rate could be compatible with that of a 2:1 conducted atrial flutter. The last echocardiography 12 months ago showed HFmrEF.
