CT of valvular heart disease.

Although the incidence of valvular heart disease is significantly less than before the introduction of antibiotic therapy, chronic mitral and aortic valve disease continues to be found in the adult population. CT examination reveals characteristic chamber volume and myocardial mass changes expected in patients with valvular obstruction and regurgitation. Furthermore, CT provides sensitive visualization of annular and valve leaflet calcification, both of which are important findings for determining the presence of disease and estimating the significance of valvular dysfunction identified on examination. Although CT is by no means the first diagnostic modality to be employed in management of patients with valvular heart disease, it does reveal the sequelae of such disease, and may, in fact, provide insight into the significance of clinical or echocardiographic findings. Improved temporal resolution will increase the accuracy of CT diagnosis, and further expand its use for diagnosing and managing patients with cardiac disease in general, and valvular heart disease, in particular.
