BACKGROUND: The left atrial appendage (LAA) is one of the major sources of cardiac thrombus formation. The morphology of the LAA correlates with stroke in patients with atrial fibrillation. In this study, we evaluated the correlation between LAA morphology and cardiac function by transthoracic echocardiography in patients with sinus rhythm. METHODS AND RESULTS: We studied 55 patients (36 men, 70 ± 11 years) who underwent cardiac computed tomography and transthoracic echocardiography...

Hypertrophic cardiomyopathy (HCM) is the most common non-ischemic cardiomyopathy, characterized by increased left ventricular wall thickness. Echocardiographic studies are essential for establishing the diagnosis, evaluating the extent of disease, and risk stratification. Echocardiography is also recommended in regular screening of the genotype-positive relatives. Two-dimensional, M-mode, and Doppler echocardiography are standard modalities in HCM diagnosis. Newer echocardiographic techniques as tissue Doppler, strain, and three-dimensional echocardiography are now widely used and can reveal subtle changes in the HCM patients...

BACKGROUND: Although assessment of left ventricular (LV) diastolic function (DF) using echocardiography is important, it is not always feasible in the clinical practice. On the other hand, left atrial (LA) overload shown by electrocardiogram (ECG) indicates LA pressure rise and LA dilatation. The purpose of this study is to examine whether LA overload by ECG can be used as an aid for evaluation of LVDF. METHODS: There were 117 subjects who underwent echocardiography and ECG on the same day...

BACKGROUND: A speckle tracking echocardiographic (STE) strain imaging can predict myocardial viability. The study compared the STE strain imaging using low-dose dobutamine stress with 18 fluoro-deoxyglucose positron emission tomographic (18 FDG-PET) imaging for the detection of myocardium viability. METHODS: We studied 57 patients with ST-elevation myocardial infarction (STEMI) having angiographic evidence of total arterial cut off and akinetic myocardium. These patients underwent low-dose dobutamine echocardiography and 18 FDG-PET imaging...

BACKGROUND: Early worsening heart failure (WHF), defined as worsening of symptoms and signs of heart failure requiring intensification of medical or mechanical therapy during an admission for acute decompensated heart failure (ADHF), has recently been recognized as a risk of morbidity or mortality after the discharge. Although echocardiographic parameters of left ventricular (LV) output has been shown to be associated with long-term outcome in heart failure patients, its predictive value for early WHF has not been elucidated...

BACKGROUND: Age-related changes in cardiac morphology and function have not been unknown in the elderly. The Japanese eLderly data Of Normal echocardioGraphy (J-LONG) study is a prospective multicenter cohort study and aimed to investigate the echocardiographic data in the healthy Japanese elderly. METHODS: Thirty domestic facilities participated in this study, and 130 healthy subjects (57 men, 73 women, 79.6 ± 4.7 years, range 75-98 years, interquartile range 76-82 years) were enrolled in this cohort...

This review focused on right ventricular (RV) three-dimensional echocardiography (3DE) and discussed the following agenda. First, we summarized the clinical RV anatomy and function-related RV3DE use followed by the explanations about 3DSTE image acquisition, including pitfall. Next, we reviewed the reliability and feasibility of RV volume and RV ejection fraction measurements during the last decade. Besides, we described the techniques that might overcome the dropout images at RV anterior and out tract including the current limitations...

BACKGROUND: The ratio of transmitral early filling velocity to early diastolic strain rate (E/e'sr) has recently emerged as a novel and accurate non-invasive measure of left ventricular (LV) filling pressure. This systematic review and meta-analysis aimed to give an overview of the possible clinical implications of E/e'sr. METHODS: We conducted a systematic review and meta-analysis of all studies involving E/e'sr. Of 598 identified studies, 16 met our inclusion criteria...

BACKGROUND: Previous studies showed that the mitral inter-commissural (IC) distance differed by a few millimeters between the systolic and diastolic cardiac cycles. However, sizing of the mitral annuloplasty ring with a ring sizer, which should be performed in the systole, is performed in diastole during hyperkalemic cardioplegic arrest. The aim of this study was to investigate whether three-dimensional transesophageal echocardiography (3D-TEE) measurements of the mitral valve in end-systole are effective to determine the size of the annuloplasty ring...

Cardiac imaging modalities are essential for the management of cardiac diseases. Multimodality imaging, such as echocardiography, cardiac computed tomography (CT), cardiac magnetic resonance imaging, and fluoroscopy, is required for assessing cardiac condition. In recent years, fusion imaging, which integrates different imaging modalities on the same screen, has been developed. Because the fusion imaging is able to merge the advantages of each modality, it has the potential to be valuable for accurate diagnosis as well as the planning of therapeutic strategies...

Lone atrial fibrillation (AF) can cause functional mitral regurgitation (MR), commonly referred to as "atrial functional MR (AFMR)." This type of MR has recently received much attention as an important cause of heart failure, and it represents a considerable therapeutic target in heart failure patients with AF. Mitral annular dilatation due to left atrial (LA) dilatation can be recognized as an original cause of AFMR, whereas the exact cascade of AFMR etiologies has not been established. AFMR is typically classified as Carpentier type I, and is likely to have a central jet...

BACKGROUND: Secondary or functional mitral regurgitation (FMR) has been reported associated with poor prognosis in patients with ischemic or non-ischemic cardiomyopathy. Prognostic impact of the FMR in myocardial infarction with preserved ejection fraction (MIpEF) is unknown. The aim of this study was to investigate predictors and prognostic impact of FMR in MIpEF. METHODS: A total of 556 patients with MIpEF were selected from the Bell Land General Hospital MI (BELAMI) registry (n = 953)...
