Recent research has identified cases of sustained FAT originating from the interatrial septum (IAS); a subset of cases presents a unique challenge, with foci originating from the peri-patent foramen ovale (peri-PFO), requiring specialized management during catheter ablation.

Atrial tachycardia (AT) originating from the left atrial appendage (LAA) is uncommon and the most difficult arrhythmia to eliminate. Therefore, we present the case of a 5-year-old girl with tachycardia-induced.

Recent data suggests that high PVC burden may lead to the development of PVC-induced cardiomyopathy (PVC-CM) even in patients without structural heart disease. Both antiarrhythmic drugs (AADs) and catheter ablation (CA) are recognized treatment modalities for any cardiac arrhythmias.

Atrial cardiomyopathy represents structural and electrophysiologic abnormalities associated with atrial fibrillation (AF). Fibrosis, visualized with late gadolinium enhancement on cardiac magnetic resonance imaging (MRI), is associated with low voltage on electroanatomic mapping1, and ablation outcomes 2.

Abstract Introduction In hypertrophic cardiomyopathy (HCM), atrial fibrillation (AF) has historically been regarded to have a deleterious impact on clinical course, strongly associated with progressive heart failure (HF) symptoms. Therefore, we evaluated the impact of AF on QoL utilizing patient reported outcome measures (PROMs).

ABSTRACT Atrial fibrillation (AF) is the most common cause of arrhythmia-induced cardiomyopathy. Effective management strategies include medical therapy for rate and rhythm control, catheter ablation (CA), and goal-directed medical therapy.

Fragmented QRS is a marker of myocardial scar and consequent arrhythmias in ischemic and nonischemic cardiomyopathy. Multiple accessory pathways can occur and radiofrequency catheter ablation is effective. Splintered and polyphasic QRS of Ebstein’s anomaly can also be considered as fragmented QRS as per the new terminology.

The patient was found to have a "concealed" posteroseptal pathway (WPW without delta waves) confirmed to have SVT at EP study and was ablated. Here is the Electrophysilogist's note: "Only 1 pathway attachment could be ablated, the second one deep within the CS could not be ablated with high power.

The prevalence in patients with co-existent atrial fibrillation (AF) and the impact of catheter ablation (CA) is unknown. CA improves both EOV and VE/VCO2 in AF-induced cardiomyopathy. Fewer patients had an abnormal VE/VCO2 gradient after CA [25 (48.1%) vs. 16 (34.0%), p =0.004].

Atrail electroanatomic voltage mapping (Atrial-EAVM) and late gadolinium enhancement imaging (Atrial-LGE) quantify the functional and anatomic extent of atrial fibrosis, a central component of atrial cardiomyopathy. Functional and anatomic measures of atrial fibrosis define the extent of atrial cardiomyopathy. Key Finding.
