REVIEW
Tsutomu Takagi
Evaluation of diastolic dysfunction and diagnosis of heart failure with preserved ejection fraction (HFpEF) by echocardiography are routinely performed at rest. However, many patients with modest HFpEF develop symptoms such as dyspnea only during exercise. Therefore, echocardiographic analysis at rest could be insufficient to identify these patients. Recent studies have demonstrated the utility of diastolic stress echocardiography to evaluate diastolic dysfunction during exercise. This review attempts to summarize and discuss current studies in diastolic stress echocardiography...

BACKGROUND: This study aimed to assess the prevalence of right ventricular diastolic dysfunction (RVDD) and its potential predictors in peripartum cardiomyopathy (PPCM) patients. METHODS: This was a cross-sectional study carried out in Nigeria. RVDD was defined and graded using Doppler filling and myocardial tissue Doppler velocities obtained at tricuspid annular level. RESULTS: Forty-three subjects with PPCM and mean age of 26.6 ± 7.0 years were recruited over 6 months...

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...

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...

BACKGROUND: Fetal echocardiography is a complete two-dimensional and Doppler ultrasound evaluation of the human fetal cardiovascular system. It is completely noninvasive, harmless, and also serves as the fetal electrocardiogram. AIM: To analyze the fetal echocardiographic cases referred to a tertiary cardiac center. MATERIALS, METHODS, AND RESULTS: A total of 478 cases of fetal echocardiograms performed over a period of 5.5 years were compiled and analyzed...

The Valsalva maneuver is an easily performed maneuver with an interesting hemodynamic effect which can be used to aid accurate echocardiographic diagnosis. However, correct adequate performance is often missed. Here, we aim to describe the performance of an adequate Valsalva maneuver and the correct interpretation of its effect. The Valsalva hemodynamic effect consists of four basic phases which can be used in echocardiography to yield an accurate diagnosis. Valsalva is used to decrease preload and provoke left ventricular outflow tract (LVOT) gradient in dynamic LVOT obstruction...

BACKGROUND: Chagas disease (CD) is highly endemic in Latin America, and has been emerging in developed countries. Early diagnosis of left ventricular (LV) systolic dysfunction, routinely done by echocardiography, is crucial for therapy. Speckle tracking echocardiography allows determination of LV segmental rotations, twist/torsion, and this analysis may disclose an unapparent myocardial contractile deficit in initial stages of CD. Therefore, this study aimed to highlight a possible unapparent myocardial contractile deficit in CD indeterminate form (IF) by a comprehensive torsional mechanics analysis...

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...
