Echocardiography has the long development history beginning with amplitude imaging. Nowadays, two- and three- dimensional imaging are standard tools available in almost every echocardiography machine. Myocardial deformation imaging is gaining popularity out of research projects. The future will bring new and sophisticated tools for echocardiographic analysis such intracardiac flow imaging and an automated 3D volume calculation.
Left ventricular ejection fraction (LVEF) is the most frequently used echocardiographic parameter. LVEF based heart failure classification, timely intervention in a patient with valvular disease (e.g. aortic stenosis, mitral regurgitation), deterioration of myocardial function in a patient treated with chemotherapy; all need a simple LVEF value for decision-making process.
