introduction: the correlation of central venous pressure (cvp) with inferior vena cava (ivc) sonographic diameter has been reported in several studies. however, few studies have attempted to find the best anatomic location of measurement. therefore, the purpose of this study was determining the best anatomic location to find precise correlation between cvp and ivc diameter using transesophageal...

To compare the diagnostic value of transesophageal and transthoracic echocardiography in infective endocarditis, paired transesophageal and transthoracic echocardiograms were obtained prospectively for 66 episodes of suspected endocarditis in 62 patients. Echocardiographic results were compared with the presence or absence of endocarditis determined by pathologic or nonechocardiographic data fr...

OBJECTIVE To report the role played by transesophageal echocardiography during implantation of self-expanding aortic endoprostheses (stent) at a hemodynamics laboratory. METHODS Thirteen patients underwent stent implantation in the descending thoracic aorta with the aid of transesophageal echocardiography during the entire procedure. Indications for stenting were as follows: 8 aortic dissecti...

Transesophageal atrial pacing study was used to document arrhythmias in 67 infants and children age 2 months to 16 years (mean, 8.3 years), who had palpitations or symptoms suggesting tachyarrhythmias but had no electrocardiographic documentation of cardiac dysrhythmias. The transesophageal pacing and medical records were reviewed retrospectively. In 47 of 67 (70%) of the infants and children w...

OBJECTIVE The present study was performed to compare coronary flow reserve by transesophageal Doppler echocardiography and intracoronary Doppler flow wire measurements in patients with LAD disease. METHODS 17 patients with various degree of LAD stenosis were studied. Intracoronary LAD Doppler measurements were performed at baseline and after intracoronary injection of 18 micrograms adenosine....

We have previously reported a standardized 10-step sequence of monoplane (transverse plane) transesophageal two-dimensional echocardiographic views and a standardized 7-step vertical plane examination, both suitable for expeditious intraoperative use by the beginning practitioner. A multiplane transesophageal examination involves transverse plane views, vertical plane views and the remaining "i...

Several formulas exist for estimating left ventricular volumes and ejection fraction using conventional two-dimensional echocardiography from transthoracic views. Transesophageal imaging provides superior resolution of endocardial borders but employs slightly different scan planes. The estimation of left ventricular volumes by transesophageal echocardiography has not been validated in human pat...

INTRODUCTION Transesophageal echocardiography was introduced 4 decades ago. Its use have had very limited clinical indication. Now it has become very useful clinical tool. Indications for its use are almost as indications for transthoracic echocardiography, especially to assess deeper cardiovascular structures. Transesophageal echocardiography is semi-invasive examination with small number of c...

background rheumatismal mitral stenosis is less common today than it was several decades ago, but it is a common cause of mitral stenosis (ms) in the developing world. mitral valve stenosis symptoms include fatigue, palpitations, and shortness of breath especially with exertion. objectives the purpose of this prospective study was to determine the incidence of left atrial (la) thrombus and the ...

background: stroke, one of the most important causes of morbidity and mortality in the world, is of great importance in young adults (15-45 years), amongst whom the causes of stroke and transient ischemic attack (tia) are different from those in older ages and a significant portion of them have no known etiology. patent foramen ovale (pfo) is considered a probable cause in this group. methods: ...
