Evaluating valvular heart disease requires a multi-parametric analysis of valvular pathology, hemodynamic derangements, and impact on ventricular size and function. The capability to perform real-time three-dimensional (3-D) imaging has vastly strengthened the already established role of echocardiography. CT and MRI advances have led to their use as daily clinical tools. Two-dimensional and 3-D echocardiography and Doppler modalities allow for accurate assessment of valvular lesions, pressure gradients, stenotic valve orifice areas, pulmonary artery pressures, intracardiac pressures, and regurgitant volumes. Quantitation of chamber volumes has become more accurate and reproducible with 3-D echocardiography, CT, and cardiac MRI. Although ultrasound imaging is the primary tool, the other techniques provide adjuvant or alternate options to examine valvular heart disease. This array of imaging modalities is likely to provide greater insights into the pathophysiology of valvular heart disease, new pointers to prognosis, and also guide innovative treatment strategies.
