Summary: Detailed evaluations of left atrial function using speckle tracking echocardiography (STE) can predict outcomes after catheter ablation for atrial fibrillation. Parameters reflecting left atrial compliance - reservoir and conduit strain - are independent and strong predictors of catheter ablation outcome in patients with paroxysmal atrial fibrillation and normal standard echocardiographic assessment.

Summary: The study showed that combining left atrial appendage closure and catheter ablation in persistent atrial fibrillation patients significantly improved left atrial function. However, there was no significant difference in left atrial function improvement between the combined therapy group and simple ablation group after 1-year follow-up. This suggests that most of the effects on left atrial function resulted from ablation, not left atrial appendage closure.

Summary: This study investigated the association between left atrial (LA) strain and LA fibrosis in patients undergoing totally thoracoscopic ablation (TTA) for atrial fibrillation (AF). The results showed that patients with mild LA fibrosis had a significantly lower rate of AF recurrence at 5 years after TTA compared to those with moderate or severe fibrosis. Peak LA strain was the only predictor of mild LA fibrosis, with a cutoff value of approximately 14.7%.

Summary: This study examined the post-ablation left atrial (LA) function and its impact on AF recurrence in patients with de-novo long-standing persistent AF. The results showed that patients who maintained sinus rhythm had improved LA function and better left ventricular diastolic function compared to those with AF recurrence after ablation.

Summary: The present study aimed to evaluate the potential use of MRI-assessed left atrial strain and left atrial strain rate as parameters for the diagnosis and differentiation of cardiac amyloidosis. The results showed that LAS and LASR were significantly impaired in patients with CA, indicating that MRI assessment could be a non-invasive method for diagnosing and categorizing CA.

Summary: Catheter ablation is an effective method for treating atrial fibrillation, but it may lead to atrial tissue damage and increase the risk of stiff LA physiology. Factors such as diabetes, E/Em ratio, LA pulse pressure, low LA voltage, empirical extra-PV ablation, and radiofrequency ablation duration are associated with stiff LA physiology after AFCA.

Summary: This study aimed to investigate the relationship between anatomical and functional parameters measured by cardiovascular magnetic resonance (CMR) and the recurrence of paroxysmal atrial fibrillation (pAF) patients after catheter ablation. The study found that post-ablation minimum left atrial volume, expansion index, and baseline reservoir strain were associated with AF recurrence.

Summary: This study found that left atrial reservoir strain and strain rate are impaired in patients with rheumatic mitral stenosis, and the degree of impairment is associated with new-onset atrial fibrillation at follow-up.

Summary: This study found that left atrial deformation analysis by echocardiography may be useful in predicting the risk of ATA recurrence in patients undergoing CA for AF, even in those with a normal-sized LA.

Summary: This study aimed to evaluate the ability of speckle tracking echocardiography (STE) parameters acquired during persistent atrial fibrillation (AF) to assess atrial fibrosis and predict AF recurrence after catheter ablation. The results showed that STE parameters could predict the extent of low-voltage area and AF recurrence in patients with persistent AF undergoing catheter ablation.

Summary: This study compared percutaneous catheter ablation with minimally invasive surgical ablation in terms of treating atrial fibrillation and evaluating the impact on atrial function. Surgical ablation had a more negative impact on left atrial reservoir function but was slightly more effective in suppressing arrhythmia.

Summary: The treatment of atrial tachycardia following catheter ablation of atrial fibrillation is often challenging, but new ablation approaches have shown promising results. However, long-term data on the freedom from any atrial tachycardia or any arrhythmia are still limited. This study presents 12-month success and mean 30 month follow-up data of catheter ablation of left atrial tachycardia, demonstrating high long-term clinical success rates with individual ablation strategies.

Summary: In patients with chronic coronary syndromes, left atrial dilation and reservoir dysfunction are often present in paroxysmal and permanent atrial fibrillation. These abnormalities are associated with more frequent inducible ischemia and pulmonary congestion during stress.

Summary: Catheter ablation is an effective treatment for atrial arrhythmias such as atrial fibrillation and atrial flutter, with the use of advanced imaging techniques to inform key clinical decisions and treatment approaches. Advanced imaging, combined with specialized image analysis techniques and intra-procedural electrical measurements, may improve outcomes by personalizing ablation targets. Ongoing research aims to integrate imaging with advanced analyses for personalized ablation targets to enhance catheter ablation outcomes in the future.

Summary: The volume of left atrial epicardial adipose tissue (EAT), assessed using cardiac magnetic resonance imaging, is independently associated with atrial fibrillation (AF) recurrence following catheter ablation. Integration of EAT with clinical risk factors improves prediction of AF recurrence.
