Intraoperative assessment of myocardial viability in beating heart revascularization. Clinical case

Jalilov Adkham Kakhramonovich, Vischipanov Artem Sergeevich

Ischemic dysfunction of the left ventricle is an aggravating clinical, functional and prognostic factor in patients with various types of ischemic heart disease. Ischemic myocardial dysfunction is directly related to the concepts of reversible and irreversible dysfunction, which in turn depend on the presence of a viable myocardium in the area of dysfunction and its volume. The effectiveness of surgical revascularization of the myocardium in patients with ischemic dysfunction of the left ventricle depends on the presence of a sufficient volume of viable myocardium, as well as on the importance of damage to the coronary arteries that supply the dysfunction zone, and the "shuntability" of these arteries. Taken together, we can say that all these factors must be established before surgery to determine the tactics of treatment and predict the result.
