USE OF TEE IN MINIMALLY INVASIVE CARDIAC
SURGERY
Dr. Hossam El Ashmawi
Department of Anesthesia, Cairo University, Egypt
The term “Minimally Invasive Cardiac Surgery” includes a range of surgical
procedure including off-pump coronary artery bypass grafting (OPCAB), minimally
invasive direct access coronary artery bypass grafting (MIDCAB), and Port access
procedures. Such procedures are becoming more and more popular everyday.
In OPCAB procedures TEE can be of help in assessing how well the ventricle is
tolerating the procedure, which inevitably involves manipulation of the heart by the
surgeon. Assessment of ischemia is very useful by TEE as positioning of the heart can
interfere with ECG readings.
In Minimally invasive procedures requiring cardiopulmonary bypass (CPB) and
cardioplegia a number of catheters and cannulae are inserted. As this cannot be done
under direct vision, TEE can be of help in verifying the correct positioning of these
catheters. The aim of this presentation is to summarize the clinical applications and
significance of TEE in minimally invasive cardiac procedures.
