title: [Evaluation of the severity of valvular heart disease and timing of surgery].
abstract: A better knowledge of the natural history of valvular disease and the advances in surgical techniques are allowing to improve the prognosis of patients with valvular heart disease. At present, imaging techniques, particularly Doppler-echocardiography, is the main tool to determine the diagnosis and prognosis of patients with valvular heart disease. Consequently, decision making in valvular heart disease is now days based on a combination of symptomatic status and echocardiographic findings. The main applications of Doppler-echocardiography with this purpose are summarized in this article. Therapeutic algorithms for patients with valvular heart disease are proposed, as well as the potential application of new imaging modalities appeared in the last years. The state of the art of clinical practice guidelines are also reviewed.
