Introduction: The underlying mechanism of the residual left atrial thrombus (LAT)/spontaneous echo contrast (SEC) after the onset of cardioembolic stroke (CES) is unknown. This study aims to investigate the utility of CHADS2 and CHA2DS2-VASc scores f

The low-voltage areas of left atrium (LA-LVA) have recently been of significant focus. However, very few studies have focused on the association between LA function and LA-LVA, and the mechanism of appearance of LA-LVA remains unclear. We investigate

The transient left atrial appendage (LAA) dysfunction after electrical cardioversion (CV), which is called as LAA-stunning, was found to be an important etiology of thrombus formation. The aim of the present study was to investigate the risk factors

BACKGROUND Because premature ventricular contractions (PVCs) are one of the most common arrhythmias, but with unclear causative mechanisms, we studied the hemodynamic features that can cause symptomatic PVCs.Methods and Results:We studied 109 patient

INTRODUCTION Transforming growth factor-β1 (TGF-β1 ) is an important factor that induces atrial fibrosis and atrial fibrillation (AF). The purpose of this study was to evaluate the association between TGF-β1 level and clinical factors before cathe

Background Long-lasting atrial fibrillation (AF) has been reported to be associated with an increased risk of dementia, independent of clinical stroke. However, the mechanisms or association in patients with subclinical paroxysmal AF (S-PAF) remain u

Background In the current clinical guidelines, cardiac resynchronization therapy (CRT) is recommended in heart failure (HF) patients with left bundle branch block (LBBB) with QRS width ≥150ms as Class I indication. In terms of HF patients with inte

Background Left ventricular (LV) stiffness as the passive LV filling property in the LV diastolic function has been reported to be related with the prevalence of atrial fibrillation (AF). On the other hand, a novel insertable monitoring (ICM) system

Background It remains controversial whether or not to discontinue anticoagulation therapy after catheter ablation (CA) for atrial fibrillation (AF). The reduced flow velocity of the left atrial appendage (FV-LAA) during AF causes left atrial appendag
