Figure 2 Examples of still-frames obtained from two-dimensional echocardiographic studies acquired using the miniaturized echocardiographic device. (A) Parasternal long-axis view obtained from a patient with hypertensive heart disease. (B) Parasternal long-axis view obtained from a patient with rheumatic mitral stenosis. (C) Parasternal long-axis view obtained from a patient with severe sclerocalcific aortic valve stenosis and calcification of the mitral valve. (D) Parasternal long-axis view obtained from a patient with a dilated cardiomyopathy. Ao = aorta; LA = left atrium; LV = left ventricle; RV = right ventricle.

Figure 3 Examples of color Doppler still-frames acquired using the miniaturized echocardiographic device. (A) Apical four-chamber view depicting moderately severe mitral regurgitation. (B) Apical four-chamber view depicting moderate tricuspid regurgitation. (C) Apical four-chamber view depicting moderately severe aortic insufficiency. (D) Parasternal short-axis view depicting pulmonic insufficiency. Ao = aorta; LV = left ventricle; PA = pulmonary artery; RA = right atrium; RV = right ventricle.
