BACKGROUND: There is no echocardiographic predictor of the effectiveness of tolvaptan in patients with heart failure (HF). The aim of this study was to investigate the echocardiographic predictor of responders to tolvaptan in patients with HF. METHODS: This observational study consisted of 62 consecutive in-hospital patients with HF who received tolvaptan with volume overload despite standard therapies. The echocardiography data were obtained within 1 week before the administration of tolvaptan...

BACKGROUND: Transthoracic echocardiography (TTE) is not recommended as the first-line diagnostic modality for Stanford type B aortic dissection (type-B AD). PURPOSES: The aims of this study were to evaluate the usefulness and factors influencing for the diagnosis of type-B AD using the transthoracic echocardiographic paravertebral approach (PVA). METHODS: We compared the image acquisition rate of descending thoracic aorta (DTA) and the diagnostic rate of type-B AD using TTE versus PVA...

BACKGROUND: Several studies have shown the utility of left atrial (LA) function determined by two-dimensional or three-dimensional speckle tracking echocardiography (2D- or 3D-STE) for identifying patients with paroxysmal atrial fibrillation (AF). However, whether 3D-STE is applicable for prediction of the recurrence of AF after catheter ablation (CA) remains unknown. We examined whether any 3D-STE parameters are better than 2D-STE parameters for the prediction of AF recurrence. METHODS: Forty-two patients with paroxysmal AF (58 ± 10 years old, 69% male) underwent 2D- and 3D-STE within 3 days before first-time CA...

Echo Doppler is widely available in the clinical setting, and the feasibility of coronary flow detection in the left anterior descending coronary artery has been reported as >90% with the use of a high-frequency transducer. Coronary flow detection takes only a few minutes by skilled echocardiologists, and this noninvasive technique can provide useful physiological information in patients with various types of coronary artery disease. Coronary flow velocity reserve measurement by echo Doppler is a simple and easy technique...

BACKGROUND: Surgical timing of chronic aortic regurgitation (AR) remains a matter of debate because of limited data. This study assessed the prognostic value of exercise echocardiography in asymptomatic AR. METHODS: This prospective study included 60 consecutive asymptomatic patients with isolated moderate or severe AR (mean regurgitant volume 56.7 ± 11.8 ml) and preserved ejection fraction who underwent exercise echocardiography. The clinical outcomes were defined by the presence of major adverse cardiovascular events (MACE) and the indication for aortic valve replacement (AVR) with class I or IIa classification in the current guidelines...

BACKGROUND: The accuracy of vector flow mapping (VFM) was investigated in comparison to stereo particle image velocimetry (stereo-PIV) measurements using a left ventricular phantom. VFM is an echocardiographic approach to visualizing two-dimensional flow dynamics by estimating the azimuthal component of flow from the mass-conservation equation. VFM provides means of visualizing cardiac flow, but there has not been a study that compared the flow estimated by VFM to the flow data acquired by other methods...

BACKGROUND: We evaluated the ability of transthoracic echocardiography (TTE) to correctly identify abnormal left ventricular (LV) size, function, and mass when compared to cardiac magnetic resonance (CMR). Whilst numerous studies have compared TTE and CMR with respect to correlation between measurements and study reproducibility, few have employed categorical analysis relevant to clinical practice. METHODS: Two hundred and fifteen consecutive patients who underwent both TTE and CMR were evaluated for the presence of abnormal LV size, systolic function, and mass...

BACKGROUND: Accurate quantification of left ventricular (LV) volumes [end-diastolic volume (EDV) and end-systolic volume (ESV)] and ejection fraction (EF) is of critical importance. The development of real-time three-dimensional echocardiography (RT3DE) has shown better correlation than two-dimensional (2D) echocardiography with magnetic resonance imaging (MRI) measurements. The aim of our study was to assess the accuracy of RT3DE and 64-slice computed tomography (CT) in the evaluation of LV volumes and function using MRI as the reference standard in a real-world population with various types of heart disease with different chamber geometry...

Diastology is a study to treat diastole of the heart. Transmitral flow and pulmonary venous flow velocities recorded by pulsed Doppler echocardiography provide more important information about left ventricular (LV) diastolic dysfunction [left atrial (LA)-LV coupling] than cardiac catheterization in clinical practice; however, these waveforms are influenced by loading conditions, particularly preload. The early diastolic mitral annular and LV wall motion indices measured by tissue Doppler echocardiography can evaluate LV relaxation abnormality and filling pressure by being relatively preload independent...
