Catheter Ablation of Atrial Tachycardia in a Giant Right Atrium

JACC: Case Reports, 2020
A 25-year-old male patient with a giant right atrium presented with atrial tachycardia. Electroanatomic mapping revealed micro–re-entry from a low-voltage zone in the region of the right atrial appendage.

The 4q25 variant rs13143308T links risk of atrial fibrillation to defective calcium homoeostasis [PDF]

, 2019
Aims: Single nucleotide polymorphisms on chromosome 4q25 have been associated with risk of atrial fibrillation (AF) but the exiguous knowledge of the mechanistic links between these risk variants and underlying electrophysiological alterations hampers ...

Influence of the Residual Gensini Score on Prognosis of Patients With ST‐Elevation Myocardial Infarction

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background The residual Gensini score (rGS) was developed to quantify the severity of coronary atheroma burden after coronary revascularisation. The predictive value of the rGS for clinical outcomes in patients with ST‐segment elevation myocardial infarction (STEMI) remains unexplored.

Modes of Initiation of Two Types of Atrial Reentry in a Patient with Typical Atrial Flutter: Isthmus-dependent Micro-reentry versus Macro-reentry

Journal of Arrhythmia, 2005
We studied the modes of initiation of two types of atria] reentrant tachycardias (i.e., microreentry isthmus tachycardia and counterclockwise atrial flutter) in a 39-year-old male with typical atrial flutter.

Explainable artificial intelligence for heart rate variability in ECG signal

Healthcare Technology Letters, 2020
Electrocardiogram (ECG) signal is one of the most reliable methods to analyse the cardiovascular system. In the literature, there are different deep learning architectures proposed to detect various types of tachycardia diseases, such as atrial ...

Catheter Ablation of Tachyarrhythmias in Small Children [PDF]

, 2005
An estimated 80,000-100,000 radiofrequency ablation (RFA) procedures are performed in the United States each year.1 Approximately 1% of these are performed on pediatric patients at centers that contribute data to the Pediatric Radiofrequency Registry.2 ...

Association of COPD with adverse outcomes in heart failure patients with preserved ejection fraction

ESC Heart Failure, Volume 12, Issue 2, Page 799-808, April 2025.
Abstract We performed a systematic review and meta‐analysis to detect the impact of chronic obstructive pulmonary disease (COPD) on the prognosis of heart failure patients with preserved ejection fraction (HFpEF). We systematically screened eligible literature from three electronic databases, PubMed, EMBASE and Cochrane Library, up to April 2023.

Ablation of Focal Atrial Tachycardia from a Large Left Atrial Diverticulum Using 3D Printing

Methodist DeBakey Cardiovascular Journal
We present a case of a 45-year-old male with symptomatic supraventricular tachycardia. Electrophysiology study and 3-dimensional (3D) electroanatomic mapping showed a focal atrial tachycardia originating from a large left atrial diverticulum.

Inter/Intra‐Atrial Dissociation in Patients With Maze Procedure and Its Clinical Implications: Pseudo‐Block and Pseudo‐Ventricular Tachycardia

Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, 2020
Background Severe conduction delay and inter/intra‐atrial dissociation may occur in patients who undergo an extensive catheter ablation or a maze procedure for atrial tachyarrhythmia.
