BACKGROUND: Therapeutic uncertainty is inherent in decisions in patients with patent foramen ovale (PFO) and cryptogenic stroke. We aimed to determine clinical implications of PFO identification in transesophageal echocardiography (TEE) after a cryptogenic ischemic stroke. METHODS: Consecutive TEE done between 2011 and 2015 in patients with previous cryptogenic stroke was evaluated. Clinical implications of PFO identification (closure and/or medical therapy) were retrieved from the medical records and discharge summaries...

BACKGROUND: Indoxyl sulfate (IS), a uremic toxin, has been reported to have hypertrophic effects on the heart. Previous studies, however, have shown no association between elevated IS levels and cardiovascular outcomes in hemodialysis patients. We hypothesized that, despite left ventricular (LV) hypertrophy, myocardial contractility and ventricular-arterial coupling would remain preserved, and that this would explain the reason for the absence of prognostic impact of IS. METHODS: We evaluated the association of IS with LV structure, contractility, vascular function, and mechanical efficiency (ventricular-arterial coupling and stroke work/pressure volume area) in 154 patients on hemodialysis, using echocardiography-based pressure-volume loop assessment...

Exercise stress testing has been widely undertaken for the diagnosis of heart diseases. The accurate assessment of clinical conditions can be conducted by comparing the findings obtained from the results of stress echocardiography with the changes in the blood/heart rate and electrocardiograms. Numerous overseas studies have reported the utility of stress echocardiography in diagnosing myocardial ischemia; in Japan, the use of this modality for this purpose was included in the national health insurance reimbursable list in 2012...

BACKGROUND: It is unclear how upper septal hypertrophy (USH) affects Doppler-derived left ventricular stroke volume (SV) in patients with AS. The aims of this study were to: (1) validate the accuracy of 3D transesophageal echocardiography (TEE) measurements of the left ventricular outflow tract (LVOT), (2) evaluate the differences in LVOT geometry between AS patients with and without USH, and (3) assess the impact of USH on measurement of SV. METHODS: In protocol 1, both 3D TEE and multi-detector computed tomography were performed in 20 patients with AS [aortic valve area (AVA) ≤ 1...

BACKGROUND: The left atrial appendage (LAA) flow velocity is an important factor for thrombus formation in patients with non-valvular atrial fibrillation (NV-AF). Recently, the relation of plasma brain natriuretic peptide (BNP) levels and thromboembolism has been reported in patients with NV-AF. The aim of this study was to determine whether the plasma BNP is predictive of lower LAA flow velocity in patients with NV-AF and normal left ventricular (LV) systolic function. METHODS AND RESULTS: A total of 184 patients with NV-AF (132 men; 65 ± 12 years, LV ejection fraction; 65 ± 10%) underwent transthoracic echocardiography, transesophageal echocardiography (TEE), and measurement of plasma BNP...

Left ventricular (LV) diastolic function can be evaluated by echocardiographic indices of LV relaxation/restoring forces, diastolic compliance, and filling pressure. By using a combination of indices, diastolic function can be graded and LV filling pressure estimated with high feasibility and good accuracy. Evaluation of diastolic function is of particular importance in patients with unexplained exertional dyspnea or other symptoms or signs of heart failure which cannot be attributed to impaired LV systolic function and to assess filling pressure in patients with heart failure and reduced LV ejection fraction...

BACKGROUND: The purpose of this study was to investigate associations between right ventricular (RV) function and left ventricular (LV) diastolic function in patients with reduced LV ejection fraction (LVEF) and preserved LVEF. METHODS: A total of 139 patients who had undergone echocardiography were recruited. LV diastolic function was determined as the ratio of mitral inflow E to mitral e' lateral annular velocities (E/e'). RV function was determined as the RV index of myocardial performance (RIMP)...

BACKGROUND: Transthoracic echocardiography (TTE) has been used to assess coronary sinus blood flow (CSBF), which reflects total coronary arterial blood flow. Successful angioplasty is expected to improve coronary arterial blood flow. Changes in CSBF after percutaneous coronary intervention (PCI), as assessed by TTE, have not been systematically evaluated. HYPOTHESIS: TTE can be utilized to reflect increased CSBF after a successful, clinically indicated PCI. METHODS: The study cohort included 31 patients (18 females, 62 ± 11 years old) referred for diagnostic cardiac catheterization for suspected coronary artery disease and possible PCI, when clinically indicated...
