Abstract

Mechanical stresses on the walls (endocardium) of the heart (myocardium), play an important role in the development of heart disease. One tool used by cardiologists in making a diagnosis is the echocardiogram. An echocardiogram uses ultrasonic pulses to produce images of the changes of shape of the left ventricle of the heart in two dimensions over time. The present research involved the development of software to automatically calculate wall stress maps and eventually provide a graphical representation as a diagnostic tool for a cardiologist. The fluid mechanics program [1] has been described previously. The program uses the shapes of the ventricle at various time
