Diagnostic medical sonogramUltrasound exam of the heart, also known as echocardiography, is performed to assess heart size, structural abnormalities or congenital anomalies. Sonography enables the physician to observe heart motion and blood flow in real time. Color and Spectral Doppler sonography are specific techniques that are used in echocardiography to evaluate the direction and velocity of blood flow throughout the heart chambers, valves, inflow and outflow vessels.

The parasitic disease Chagas is endemic in 21 countries in the Americas, with 28,000 new cases each year. Left untreated the disease can lead to irreversible damage to multiple organ systems, including the heart.

The effects of chronic Chagas disease on the heart include cardiomyopathy, abnormal heart rhythms, and aneurysms within the heart apex. Echocardiography could be utilized to identify and monitor progression of chronic Chagas disease.
