Figure 1. Echocardiographic images of valvular heart disease. Degenerative calcific aortic stenosis is shown on a mid-esophageal aortic valve short-axis view on transesophageal echocardiography (A); rheumatic mitral stenosis is shown on the parasternal short-axis view aortic level on transthoracic echocardiography (B); aortic regurgitation detected on color Doppler in the parasternal long-axis view on transthoracic echocardiography (C); mitral valve posterior prolapse with significant mitral regurgitation on 2-dimensional (D) and color Doppler (E) in the mid-esophageal 2-chamber view on transesophageal echocardiography; and failure of tricuspid valve coaptation during systole (F) and significant tricuspid regurgitation on color Doppler (G) in the apical 4-chamber view on transthoracic echocardiography.
