Exploring Hidden Left Ventricular Dysfunction in COPD Patients without Pulmonary Hypertension [PDF]

Al-Azhar International Medical Journal
Background: Atrial fibrillation (AF) is associated with left atrial (LA) mechanical dysfunction and an increased risk of thromboembolism, most commonly originating from the left atrial appendage (LAA).

Systematic Analysis of Gene Expression Differences between Left and Right Atria in Different Mouse Strains and in Human Atrial Tissue [PDF]

, 2011
Background: Normal development of the atria requires left-right differentiation during embryonic development. Reduced expression of Pitx2c (paired-like homeodomain transcription factor 2, isoform c), a key regulator of left-right asymmetry, has recently ...

Percutaneous or mini-invasive surgical radiofrequency re-ablation of atrial fibrillation: Impact on atrial function and echocardiographic predictors of short and long-term success

Frontiers in Cardiovascular Medicine, 2022
ObjectivesThe aim of this study was to compare percutaneous catheter ablation vs. minimally invasive surgical ablation, evaluating the impact of repeated ablation on atrial function, and evaluating predictors of atrial fibrillation (AF) recurrence ...

Impaired left atrial reservoir and conduit strain in patients with atrial fibrillation and extensive left atrial fibrosis

, 2021
Background Atrial fibrillation (AF) is associated with profound structural and functional changes in the atria. In the present study, we investigated the association between left atrial (LA) phasic function and the extent of LA fibrosis using advanced ...

Predictive value of left atrial strain in relation to atrial fibrillation following acute myocardial infarction

, 2022
Background: Atrial fibrillation (AF) is the most common arrythmia following ST-segment elevation myocardial infarction (STEMI) and can lead to stroke and other heart-related diseases. This study aimed to determine the prognostic value of left atrial (LA)

Left atrial strain as sensitive marker of left ventricular diastolic dysfunction in heart failure [PDF]

, 2020
Aims The purpose of this retrospective analysis was to examine the association of left atrial (LA) strain (i.e. LA reservoir function) with left ventricular diastolic dysfunction (DD) in patients with heart failure with reduced and preserved left ...
