The diagnosis is usually first suggested by a transthoracic echocardiogram, part of the standard pre-transplantation work-up.
12.
In this setting, a much more accurate measurement of ejection fraction, than a transthoracic echocardiogram can provide, is necessary.
13.
The anterior / posterior position is preferred as it minimizes transthoracic electrical impedance by " sandwiching " the heart between the two pads.
14.
Radionuclide ventriculography gives a much more precise measurement of left ventricular ejection fraction ( LVEF ) than a transthoracic echocardiogram ( TTE ).
15.
Dr Sloth was the first non-cardiologist who took up transthoracic echocardiography as a part of the clinical evaluation of every patient he examined.
16.
Cardiac pacemaker therapy would not become reality in clinical medicine until the 1950s ( transthoracic and temporary pacing ) and the 1960s ( permanent pacing ).
17.
A transthoracic echocardiogram ( TTE ) indicates if there is an aortic regurgitation, but a 3-D transesophageal echocardiogram can give a better view of the aortic valve.
18.
Transthoracic lung biopsies are preferable for diagnosis of constrictive BO compared to transbronchial biopsies; regardless of the type of biopsy, a diagnosis may only be achieved by examination of multiple samples.
19.
Because of inability to obtain accurate images of the left atrium and the pulmonary veins with a transthoracic echocardiogram, a transesophageal echocardiogram may be necessary in some cases to determine the severity of MI.
20.
Below is a transthoracic image-for those with TEE / TOE experience, simply invert the image mentally, but the concept is the same . ( Edit : Image is not present currently.
