BACKGROUND: It has been proved that multi-contrast cardiovascular magnetic resonance (CMR) vessel wall imaging could be used to characterize carotid vulnerable plaque components according to the signal intensity on different contrast images. The signal intensity of plaque components is mainly dependent on the values of T1 and T2 relaxation. T1 mapping recently showed a potential in identifying plaque components but it is not well validated by histology. This study aimed to validate the usefulnes...

OBJECTIVES: Increased arterial stiffness is currently recognized as an independent risk factor for atrial fibrillation, although the pathophysiological mechanisms remain unclear. This study aimed to investigate the association of arterial stiffness with left atrial (LA) volume and phasic function in a community-based cohort. METHODS: We included 1156 participants without overt cardiovascular disease who underwent extensive cardiovascular examination. Arterial stiffness was evaluated by cardio-an...

Background Atrial fibrillation (AF) is the most common arrhythmia in hypertrophic cardiomyopathy (HCM) and is associated with adverse outcomes in HCM patients. Although the left atrial (LA) diameter has consistently been identified as a strong predictor of AF in HCM patients, the relationship between LA dysfunction and AF still remains unclear. The aim of this study is to evaluate the LA function in patients with non-obstructive HCM (NOHCM) utilizing cardiovascular magnetic resonance feature tra...

Purpose of Review Atrial fibrillation (AF) is the most common arrhythmia in adults. The number of patients with AF is anticipated to increase annually, mainly due to the aging population alongside improved arrhythmia detection. AF is associated with a significantly elevated risk of hospitalization, stroke, thromboembolism, heart failure, and all-cause mortality. Echocardiography is one of the key components of routine assessment and management of AF. Therefore, the aim of this review is to brief...

: The critical role of the left atrium (LA) in cardiovascular homoeostasis is mediated by its reservoir, conduit, systolic, and neurohormonal functions. Atrial fibrillation is generally a reflection of underlying disease of the LA, especially in patients with heart failure. Disease-related LA remodelling leads to a decline in both atrial contractility and distensibility along with an impairment in the control of neurohormonal systems that regulate intravascular volume. Catheter ablation can lead...

Restoration of sinus rhythm in atrial fibrillation (AF) by radiofrequency catheter ablation (RFCA) is associated with a transient stunning of left atrial (LA) function. However, the long-term effects of different ablation strategies on LA function remain undetermined. We performed randomized controlled trial to evaluate the effects of RFCA, cryoablation, and 3D mapping-guided cryoablation on LA function of proximal AF patients within 1 year. The 3D mapping-guided cryoablation was defined as a ma...

Background Left atrial (LA) volume is a marker of cardiac remodeling and prognosis in heart failure (HF) with reduced ejection fraction (EF), but LA function is rarely measured or characterized. We investigated determinants and prognostic impact of LA reservoir function in patients with HF with reduced EF. Methods and Results In 405 patients with stable HF with reduced EF (EF, ≤40%) in sinus rhythm, we assessed LA reservoir function by both LA total EF (by phasic volume changes) and peak atrial ...

In patients with atrial fibrillation (AF), left atrial (LA) fibrosis is a major determinant of the progression to, and burden of AF. LA reservoir strain and total atrial conduction time (PA-TDI) reflect LA fibrotic content. We aimed to investigate the relation between LA reservoir strain and PA-TDI in AF patients and control subjects. Six-hundred two patients (mean age 56 years, 53% men) with first episode of AF and 342 controls (mean age 64 years, 71% men) without structural heart disease under...

Aims: Left atrial (LA) diameter is a predictor of atrial fibrillation (AF) recurrence following radiofrequency catheter ablation (RFA). However, LA volume (LAV) is more accurate in assessing LA size. Studies evaluating LAV as a predictor of AF recurrence are contradictory; therefore, we performed a meta-analysis to assess whether LAV is an independent predictor of AF recurrence following RFA. Methods and results: All studies reporting LAV/LAV index (LAVi) as a predictor of AF recurrence followin...

Aims Left atrial (LA) function index (LAFI) is a rhythm-independent index that combines LA emptying fraction (LAEF), adjusted LA volume (LAVi), and stroke volume. We evaluated LAFI as a predictor of long-term survival in outpatients with heart failure with reduced ejection fraction (HFrEF). Methods and results For 3 years, we followed up 203 outpatients with a left ventricular ejection fraction <40%, who were clinically stable and on optimal therapy. The endpoint was all-cause death. LAFI was ca...

Silent atrial fibrillation (AF) may be the cause of some cryptogenic strokes (CrS). The aim of the study was to analyse atrial size and function by speckle tracking echocardiography in CrS patients to detect atrial disease. Patients admitted to the hospital due to CrS were included prospectively. Echocardiogram analysis included left atrial ejection fraction (LAEF) and atrial strain. Insertable cardiac monitor was implanted, and AF was defined as an episode of ≥1 min in the first year after stro...
