Transesophageal Echocardiographic Examination of Left Subclavian Artery Branches.

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.

Three-Dimensional Echocardiographic Assessment of Lambl's Excrescences on the Aortic Valve.

The present case reports demonstrate the incremental value of three-dimensional echocardiography over multiplane transesophageal two-dimensional imaging in the assessment of Lambl's excrescences (strands) involving the aortic valve.

Transesophageal Echocardiographic Diagnosis of Coronary Stenosis in a Stroke Patient.

This study represents another example of the usefulness of transesophageal echocardiography in the assessment of stenosis involving the proximal, mid, and distal coronary arteries in stroke patients referred for exclusion of a cardiac source of embolism.

Transpharyngeal Echocardiographic Diagnosis of Carotid Bulb and Left Internal Carotid Artery Stenosis.

We report a patient in whom we were able to make an accurate diagnosis of left carotid bulb and left internal carotid artery stenosis by carefully and slowly withdrawing the probe from the esophagus into the pharynx.
