FREE RADICAL MODIFICATION OF PROTEINS AND LIPID IN ATRIAL FIBRILLATION

Кубанский научный медицинский вестник, 2016
At 105 patients with paroxysmal and permanent form of atrial fibrillation against the background of coronary heart disease (CHD) and without CHD were studied concerning the levels of peroxidation products and protein-Lipid rows.

Study of P wave dispersion in patients with paroxysmal atrial fibrillation and its role in prediction of atrial fibrillation recurrence

The Egyptian Heart Journal
Background It has been known that increased P wave duration and P wave dispersion reflect prolongation of intra-atrial and interatrial conduction time and the inhomogeneous propagation of sinus impulses, which are well-known electrophysiologic ...

Ultrasonic characterization of the pulmonary venous wall: echographic and histological correlation [PDF]

, 2002
Background: Pulmonary vein isolation with radiofrequency catheter ablation techniques is used to prevent recurrences of human atrial fibrillation. Visualization of the architecture at the venoatrial junction could be crucial for these ablative techniques.

Left Atrial Appendage Aneurysm with Paroxysmal Atrial Fibrillation

The Heart Surgery Forum, 2012
Aneurysm of the left atrial appendage is extremely rare, and afflicted patients most commonly present with atrial tachyarrhythmia or thromboembolism. For these patients, resection of the aneurysm is the recommended and preferred therapy. We present the case of a 57-year-old woman who was found incidentally to have a large aneurysm of the left atrial ...

Interplay of Probe Stability and Oscillation During Very‐High‐Power Short‐Duration Ablation in Pulmonary Vein Isolation for Atrial Fibrillation

Pacing and Clinical Electrophysiology, EarlyView.
This graphical abstract presents a comprehensive analysis of probe stability and oscillation during very high‐power short‐duration (vHPSD) pulmonary vein isolation (PVI) for atrial fibrillation. The findings indicate that oscillation velocity serves as a more reliable predictor of impedance drop and temperature changes than contact force alone ...

Recurring patterns of atrial fibrillation in surface ECG predict restoration of sinus rhythm by catheter ablation [PDF]

, 2014
Background Non-invasive tools to help identify patients likely to benefit from catheter ablation (CA) of atrial fibrillation (AF) would facilitate personalised treatment planning.

Intra‐Procedural Three‐Dimensional Rotational Angiography in Cryoballoon Ablation of Atrial Fibrillation: An RCT

Pacing and Clinical Electrophysiology, EarlyView.
ABSTRACT Background The impact of various imaging techniques on the safety and outcomes of atrial fibrillation (AF) ablation remains unclear. Intra‐procedural three‐dimensional rotational angiography (3DRA) is the least used imaging method despite some benefits.

Lifestyle modification in atrial fibrillation: Mechanisms, phenotypes and ablation outcomes

Experimental Physiology, EarlyView.
Abstract Atrial fibrillation (AF) is the most prevalent sustained cardiac arrhythmia and is associated with significant morbidity, mortality and healthcare utilization. Catheter ablation is increasingly used as a rhythm‐control intervention for patients with symptomatic paroxysmal and persistent AF, yet recurrence rates remain suboptimal.

Cryoballoon Ablation for Atrial Fibrillation

Indian Pacing and Electrophysiology Journal, 2012
Focal point-by-point radiofrequency catheter ablation has shown considerable success in the treatment of paroxysmal atrial fibrillation. However, it is not without limitations.
