Sanatorio Otamendi. CABA. One of the main causes of left ventricular dysfunction is coronary artery disease. A transient ischemic event generates an imbalance between oxygen supply and demand with reversible damage to myocardial tissue. If persistent in time, this eventevolves from progressive ventricular dysfunction into heart failure. The management of this condition is based on the optimal medical therapy including drugs and, in some cases, combined with myocardial revascularization as an option to improve both quality and quantity of life.The correct identification of a viable myocardium is essential to know what treatment strategy should be followed. The cardiac magnetic resonance imaging is considered the best imaging modality for the study of myocardial viability, its size, function, valves, and even the aorta. The positron emission tomography imaging modality is also a viable option for a complete study of myocardial viability. Revascularization in patients with severe ventricular dysfunction and myocardial viability reduces mortality, cardiovascular mortality, and hospital stays. heart failure, myocardial viability, severe left ventricular dysfunction, coronary revascularization http://www.raci.com.ar/contenido/art.php?recordID=MTgwNA== http://recursos.meducatium.com.ar/contenido/articulos/24201090116_1804/pdf/24201090116.pdf
