Implication
May support intraoperative high-frequency epicardial echocardiography for CABG anastomosis assessment; leaves open prospective validation before routine adoption.
Structured PICO
Does intraoperative high-frequency epicardial echocardiography accurately measure coronary artery bypass graft anastomoses and detect technical errors?
P
Population
12 dogs studied after coronary artery bypass grafting (experimental validation) and 12 patients undergoing coronary artery bypass grafting (clinical applicability)
I
Intervention
Intraoperative high-frequency epicardial echocardiography
C
Comparator
Histological measurement after perfusion fixation (in the animal model)
O
Outcome
Maximum luminal diameter of the anastomosis and detection of technical errorssurrogate
High-frequency epicardial echocardiography is a feasible and accurate method for the intraoperative evaluation of coronary artery bypass graft anastomoses and the detection of technical errors.
