Integrated Management of Persistent Atrial Fibrillation

Biomedicines
The global incidence of atrial fibrillation is on the rise. Atrial fibrillation, a complex disease, heightens the likelihood of heart failure, stroke, and mortality, necessitating careful attention.

Longstanding Persistent Atrial Fibrillation Ablation: How Do You Perform It? [PDF]

Journal of Cardiac Arrhythmias, 2020
Longstanding-persistent atrial fibrillation is one of the most challenging arrhythmias to treat. While radiofrequency catheter ablation is highly effective in paroxysmal atrial fibrillation, pulmonary vein antral isolation (including posterior wall ...

Altered excitation-contraction coupling in human chronic atrial fibrillation [PDF]

, 2012
This review focuses on the (mal)adaptive processes in atrial excitation-contraction coupling occurring in patients with chronic atrial fibrillation. Cellular remodeling includes shortening of the atrial action potential duration and effective refractory ...

Ablation Therapy for Persistent Atrial Fibrillation

Current Cardiology Reviews, 2022
: Atrial Fibrillation (AF) is the most common form of electrical disturbance of the heart and contributes to significant patient morbidity and mortality. With a better understanding of the mechanisms of atrial fibrillation and improvements in mapping and ablation technologies, ablation has become a preferred therapy for patients with symptomatic AF ...

Ablating Persistent Atrial Fibrillation Successfully [PDF]

Current Cardiology Reports, 2012
The ablation of persistent atrial fibrillation (AF) poses many challenges compared with ablation for paroxysmal AF, including greater procedural complexity, longer procedural time, unclear endpoints, increased patient comorbidity with a greater risk of procedural complications, and lower success rate.

Comparison of electrogram characteristics in persistent atrial fibrillation

Journal of Cardiovascular Electrophysiology, 2023
AbstractIntroductionMultiple analysis techniques evaluate electrograms during atrial fibrillation (AF), but none have been established to guide catheter ablation. This study compares electrogram properties recorded from multiple right (RA) and left atrial (LA) sites.MethodsMultisite LA/RA mapping (281 ± 176/239 ± 166 sites/patient) was performed in 42 ...

Catheter ablation of atrial fibrillation : radiofrequency catheter ablation for redo procedures after cryoablation [PDF]

, 2013
Aim: To evaluate the effectiveness of two different strategies using radiofrequency catheter ablation for redo procedures after cryoablation of atrial fibrillation. Methods: Thirty patients (paroxysmal atrial fibrillation: 22 patients, persistent atrial

The Antimalarial Chloroquine Reduces the Burden of Persistent Atrial Fibrillation

Frontiers in Pharmacology, 2019
In clinical practice, reducing the burden of persistent atrial fibrillation by pharmacological means is challenging. We explored if blocking the background and the acetylcholine-activated inward rectifier potassium currents (IK1 and IKACh) could be ...

Integrating the Left Atrium Diameter to Improve the Predictive Ability of the Age, Creatinine, and Ejection Fraction Score for Atrial Fibrillation Recurrence After Cryoballoon Ablation

Anatolian Journal of Cardiology, 2023
Background: Several clinical trials have assessed predictors for atrial fibrillation recurrence following cryoballoon catheter ablation. With these predictors, a practical and new scoring system can be developed to evaluate atrial fibrillation recurrence.

Simultaneous Thoracoscopic Approach in a Patient with Long-Standing Persistent Atrial Fibrillation and Primary Lung Cancer: the First Described Case [PDF]

Brazilian Journal of Cardiovascular Surgery, 2020
Cardiac rhythm disorders are common in many patients with cancer. The management of synchronous long-standing persistent atrial fibrillation and pulmonary lesions remains a serious surgical dilemma due to the lack of clinical data and surgical guidelines.
