Abstract Myocardial protection during cardiac surgery aims to preserve myocardial function while providing a bloodless and motionless operating field to make surgery easier. The term Myocardial Protection refers to strategies and methodologies used either to attenuate or to prevent post ischemic myocardial dysfunction that occurs during and after heart surgery, Post ischemic myocardial dysfunction is attributable, in part, to a phenomenon known as ischemia-reperfusion-induced injury. Warm Heart Surgery, the use of normothermia myocardial protection has increased and routinely achieved with good results by intermittent cardioplegia with antegrade warm blood or by retrograde continuous warm blood cardioplegia, although cold crystalloid cardioplegia is associated with an excellent clinical outcome in elective surgery, blood cardioplegia techniques seem to offer superior cardiac protection in high risk situations, such as advanced left ventricular dysfunction, acutely ischemic myocardium, heart transplantation, hypertrophied myocardium. |
