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...

BACKGROUND: It has been reported that carotid intima-media thickness (IMT) correlates with the risk of stroke or cardiovascular disease. The purpose of this study was to analyze the relationships between echocardiographic findings and carotid atherosclerosis. METHODS: A total of 234 patients (62 ± 15 years) were referred for echocardiography to evaluate the left ventricular (LV) function. The LV ejection fraction, the ratio of the peak velocity of early rapid filling and the peak velocity of atrial filling (E/A), and the peak early diastolic mitral annular velocity (e') were obtained by echocardiography...

OBJECTIVES: The purpose of our study was to assess the echocardiographic and angiographic parameters in patients with symptomatic heart failure (HF) and mild diastolic dysfunction (grade I). BACKGROUND: It remains uncertain why some patients with mild diastolic dysfunction exhibit HF symptoms and others are asymptomatic. METHODS: The study enrolled 80 hospitalized patients with impaired left ventricular (LV) relaxation. Patients were divided into two groups; one group had chronic functional class II to III dyspnea and the other group had no symptoms of HF...

Left atrial (LA) function has a significant impact on cardiovascular diseases and has been assessed by several noninvasive methods. However, several limitations, including the dependence of image quality, single plane assessment, and time-consuming procedures, have prevented widespread clinical application of the assessment of LA function. Strain imaging using tissue Doppler echocardiography enables quantification of LA function. Recently, two-dimensional speckle tracking echocardiography (2D-STE) has been developed as a noninvasive, simple, and reproducible tool for assessment of LA function in patients with cardiovascular disease...
