Does beating heart coronary revascularization affect myocardial function, myocardial tissue injury, and clinical outcome in patients undergoing coronary artery bypass surgery?
Does beating heart coronary revascularization affect myocardial function, myocardial tissue injury, and clinical outcome in patients undergoing coronary artery bypass surgery?
This review evaluates the effects of beating heart coronary revascularization on myocardial function and clinical outcomes, addressing concerns about temporary regional myocardial ischemia during the procedure.
Current evidence on beating-heart CABG myocardial effects remains inconclusive; prospective trials needed before practice change.
Coronary artery bypass surgery on the beating heart either via a left anterior small thoracotomy (LAST) or a median sternotomy is becoming increasing popular world-wide. Concern still remains about the potential for a temporary regional myocardial ischaemia associated with the stabilisation and occlusion of the coronary during construction of the anastomosis. This review summarises the results of a series of studies intended to evaluate the effect of beating heart coronary revascularization on myocardial function, myocardial tissue injury and clinical outcome.
