Efficacy of Ablation Lesion Sets in Addition to Pulmonary Vein Isolation for Paroxysmal Atrial Fibrillation: Findings From the SMASH‐AF Meta‐Analysis Study Cohort

Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, 2019
Background The objective was to explore the efficacy of ablation lesion sets in addition to pulmonary vein isolation (PVI) for paroxysmal atrial fibrillation.

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 ...

Prospective in silico trials identify combined SK and K2P channel block as an effective strategy for atrial fibrillation cardioversion

The Journal of Physiology, EarlyView.
Abstract figure legend In silico trials were conducted in 654 virtual patients with atrial fibrillation (AF) to assess the cardioversion efficacy of three pharmacological treatments: single SK and K2P channel block and combined SK+K2P channel inhibition. Left: representative virtual AF patient with the atria inside the torso.

Changes in C-reactive protein levels when choosing different treatment strategies for atrial fibrillation

Клинический разбор в общей медицине
Background. In recent years, the issue of the occurrence of immune remodeling, including the immune cell activation and changes in cytokine secretion, is a subject of considerable debate.

Anteroposterior Diameter of the Left Atrium Determines the Occurrence of Left Atrial Tachycardia in Non-paroxysmal Atrial Fibrillation Patients after Catheter Ablation

Majalah Kardiologi Indonesia
Objectives:             The relationship between left atrial (LA) size and atrial fibrillation (AF) is well-established. However, the specifics of LA regional remodeling and its connection to left atrial tachycardia (LA-AT) post-ablation in patients ...

Repolarization adaptation to rapid change in heart rate in human models – a review

The Journal of Physiology, EarlyView.
Abstract figure legend This review focuses on non‐invasive assessment of repolarization duration and dispersion (heterogeneity) adaptation to change in heart rate (HR). HR was increased incrementally by left atrial pacing during an electrophysiology (EP) study and by a bolus injection of atropine and in a step up/down fashion by repeated right atrial ...

Virtual left atrial appendage occlusion in paroxysmal atrial fibrillation during sinus rhythm predicts variable reductions in blood stasis

The Journal of Physiology, EarlyView.
Abstract figure legend Stasis before and after left atrial appendage occlusion (LAAO) in participants with high stasis and low stasis. Stasis is predominantly located in LAA and reduced after LAAO. But in the participant with high stasis, stasis remains close to the occlusion site, indicating a potential risk for device related thrombi.

Computational modelling of the pro‐ and antiarrhythmic effects of atrial high rate‐dependent trafficking of small‐conductance calcium‐activated potassium channels

The Journal of Physiology, EarlyView.
Abstract figure legend Small‐conductance calcium‐activated potassium (SK) channels are important for atrial repolarization and can be targeted for atrial‐specific antiarrhythmic treatments. We developed a computational model with a calcium sensor to study the effects of increased pacing rate (5 Hz), which enhances SK‐channel gating and forward ...
