BACKGROUND Preoperative recognition of the presence of bicuspid aortic valve can be important in the planning of procedures. Multiplane transesophageal echocardiography may allow more accurate detection of valvular morphology than does biplane transesophageal echocardiography. METHODS AND RESULTS The studies of 710 patients who subsequently underwent… (More)
The aim of the study was to compare the accuracy of multiplane transesophageal echocardiography (TEE) with the more conventional biplane technique in the direct assessment of aortic valve area in patients with aortic stenosis. Short-axis images of the aortic valve adequate for measuring aortic valve area were obtained in all 81 patients studied by… (More)
BACKGROUND In some patients with papillary muscle rupture, the ruptured head may not prolapse into the left atrium, which makes diagnosis by transthoracic or transesophageal echocardiography difficult. METHODS AND RESULTS In an attempt to find additional or more definite diagnostic echocardiographic features, we analyzed intraoperative transesophageal… (More)
This preliminary study demonstrates the feasibility of examining the proximal segments of the branches of the left subclavian artery during probe withdrawal toward the end of a routine transesophageal echocardiographic study. The branches identified most commonly were the vertebral and the internal mammary arteries.
Utilizing a new echocardiographic system, intramyocardial coronary arteries could be demonstrated by color Doppler in a small number of open chest animals. Both intravenous and intracoronary injections of a contrast agent (Levovist) resulted in significant enhancement of color flow signals with an increase in the length, width, and the number of these… (More)
The incremental value of three-dimensional echocardiography over transesophageal multiplane two-dimensional imaging in the assessment of sinus venosus atrial septal defect is demonstrated in the present study.
In the present study, we report our experience of using three-dimensional reconstruction of transesophageal two-dimensional echocardiographic images in the assessment of aortic dissection (22 patients), aortic rupture (1 patient), aortic aneurysm without dissection (2 patients), and aortic tumor (1 patient).
