Dynamic assessment of right ventricular volumes and function by real-time three-dimensional echocardiography: a comparison study with magnetic resonance imaging in 100 adult patients.
BACKGROUND The aim of this study was to validate a novel real-time three-dimensional echocardiographic (RT3DE) analysis tool for the determination of right ventricular volumes and function inExpand

Patent foramen ovale and cryptogenic stroke in older patients.
BACKGROUND Studies to date have shown an association between the presence of patent foramen ovale and cryptogenic stroke in patients younger than 55 years of age. This association has not beenExpand

In vivo analysis of aortic valve dynamics by transesophageal 3-dimensional echocardiography with high temporal resolution.
OBJECTIVES Knowledge of aortic valve function has been obtained from experimental studies. The aim of the present study was to investigate characteristics of aortic valve motion in humans. METHODSExpand

Left atrial appendage flow velocity as a quantitative surrogate parameter for thromboembolic risk: determinants and relationship to spontaneous echocontrast and thrombus formation--a transesophageal
BACKGROUND Hemostasis in the left atrial (LA) appendage (LAA) is an important cause in the formation of thrombi. Determination of the LAA flow velocity (LAAV) could be a quantitative parameter forExpand

Percutaneous aortic valve replacement: an experimental study. I. Studies on implantation.
OBJECTIVE The purpose of this preliminary study was to devise a new surgical procedure for minimally invasive aortic valve implantation with a transluminal technique. METHODS The new collapsibleExpand

Do stroke patients with normal carotid arteries require TEE for exclusion of relevant aortic plaques?
Objectives: This study investigated (a) the hypothesis that stroke patients with aortic atheroma would show comparable atherosclerotic changes in the carotid arteries, which are easily accessible forExpand

Myxoma of the mitral valve: diagnosis by 2-dimensional and 3-dimensional echocardiography.
In this report we describe a 39-year-old patient who had left-sided hemiparesis. In search of a source of embolism, we performed transthoracic echocardiography, which did not show any abnormalities.Expand

Assessment of left atrial functional parameters using a novel dedicated analysis tool for real-time three-dimensional echocardiography: validation in comparison to magnetic resonance imaging
Real-time three-dimensional echocardiography (RT3DE) is superior to two-dimensional echocardiography in assessing left atrial (LA) parameters, but to date algorithms developed for the left ventricleExpand

Vibrational spectroscopy of the amorphous silicates
Abstract It has been demonstrated that the Si 2 O unit instead of the SiO 4 unit approach would much better explain the IR spectra of crystalline and vitreous silica and framework alumino-silicates.Expand

Therapeutic Strategies After Examination by Transesophageal Echocardiography in 503 Patients With Ischemic Stroke
Background and Purpose— Transesophageal echocardiography (TEE) is the gold standard in detecting high-risk (ie, aortic thrombi) and potential sources (ie, patent foramen ovale [PFO]) of cerebralExpand
