Assessing flow during minimally invasive coronary artery bypass: an Allen's test equivalent.
The use of a provocative test to elicit selective regional myocardial dysfunction (detected with intraoperative TEE) as a method to infer adequacy of regional myocardial perfusion following MIDCAB is described. We liken the similarity of this technique to the originally described "Allens test" for determination of collateral blood flow adequacy.
