Background Many echocardiographic features of constrictive pericarditis (CP) have been reported, but each alone has a limitation either in sensitivity or in specificity. Continuous-wave Doppler–derived flow velocity of pulmonary regurgitation…
Background Computed tomographic (CT) angiography provides high sensitivity for the detection of coronary stenosis, while its specificity is relatively low. The aim of this study was to determine the incremental…
Background Atrial fibrillation (AF) and atrial flutter (AFL) are strong atrial thrombosis (THR) risk factors. In recent-onset tachyarrhythmias, the incidence of left atrial appendage (LAA) THR, detected by transesophageal echocardiography…
Background The aim of this study was to test the effect of endurance training on the age-related changes of left ventricular (LV) twist-untwist mechanics. Aging has been shown to induce…
Background Atrial fibrillation (AF) is a risk factor for ischemic stroke and congestive heart failure. AF may cause left atrial (LA) dyssynchrony as well as electrical and mechanical remodeling. The…
Background Left atrial (LA) strain is a sensitive measure of LA mechanics. However, its relationship with rhythm outcomes after catheter ablation in patients with atrial fibrillation (AF) is not well…
Background When stratifying thromboembolic risk to patients with atrial fibrillation (AF), left atrial appendage (LAA) thrombus is currently the only echocardiographic index that absolutely contraindicates cardioversion. The aim of this…
Background Implantable device leads can cause tricuspid regurgitation (TR) when they interfere with leaflet motion. The aim of this study was to determine whether lead-leaflet interference is associated with TR…
Background Three-dimensional (3D) color Doppler transesophageal echocardiography (TEE) enables accurate planimetry of the effective regurgitant orifice (ERO) of a mitral paravalvular leak (PVL). The aim of this study was to…
Background An understanding of aortic root anatomy in bicuspid aortic valve (BAV) has not been well established. The aims of this three-dimensional transesophageal echocardiographic study were (1) to examine whether…
