Three-dimensional Parametric Imaging for Intraoperative Quantification of Regional Left Ventricular Function in Ischemic Cardiomyopathy

© 2017 Annals of Cardiac Anaesthesia | Published by Wolters Kluwer Medknow The Editor, The intraoperative assessment of regional left ventricular (LV) function using three‐dimensional (3D) echocardiographic parametric imaging is evolving as the technique has a steep learning curve. The two‐dimensional wall motion score index is a subjective and a semi‐quantitative way of describing segmental contractile dysfunction. Parametric imaging provides a finer approach; it processes more than 800 endocardial data points to develop bull’s eye diagrams of 17‐segmented LV model as described by the American Society of Echocardiography in transthoracic echocardiographic orientation.[1]
