Minimally invasive cardiac surgery or beating heart surgery requires very precise observation, explanation, diagnosis, and proper treatment of all changes in the cardiovascular system that occur during the procedure. A major concern in beating heart surgery is the risk of inducing myocardial ischemia without the circulatory support of cardiopulmonary bypass. Protection of myocardium in different stages of the perioperative period is crucial. The following issues should be taken into consideration: preoperative preparation of the myocardium, providing anesthesia techniques that may help to protect the myocardium, and the use of surgical techniques for myocardial protection. Hemodynamic alterations during dislocations of the heart require understanding of these changes and the effects they have on the myocardium. Proper monitoring during the whole procedure, correlation of all findings with the treatment and therapeutic maneuvers, and excellent cooperation between anesthesiologist and surgeon are essential for myocardial protection. New pharmacologic methods, some experimental, should be considered in near future for myocardial protection during beating heart surgery. [ABSTRACT FROM PUBLISHER] |
