Surgical revascularization of lesions of the left common trunk

A significant lesion of the left coronary common trunk (LCCT) is greater than or equal to 50% of the reference diameter. It is found in 5-7% of pathological coronary angiograms, and is often associated with multi-truncular involvement.The goals of myocardial revascularization in patients with tight CKGR stenosis are to treat angina, improve left ventricular function, prevent myocardial infarction, and improve the quality of life and life expectancy of coronary patients.Advances in interventional cardiology since the advent of active stents, the emergence of safe anti-platelet agents, and the growing experience of operators, have led to a renewed focus on the challenge of percutaneous revascularization of unprotected TCCG with greater ease and safety.The choice of treatment and the strategy for myocardial revascularization depend, on the one hand, on the patient's clinical profile and, on the other, on the angiographic characteristics of the coronary lesions.
