How to follow patients with mitral and aortic valve disease

Valvular heart diseases (VHDs) place a hemodynamic load on the left and/or right ventricle that, if severe, prolonged, and untreated, damages the myocardium, leading to heart failure and death. Because all VHDs are mechanical problems, definitive therapy usually requires valve repair or replacement. In most valve disease the onset of symptoms marks a change in disease prognosis and is usually an indication for prompt surgical correction. Echocardiography is an indispensable modality for assessing lesion severity, its effect on cardiac function, and the proper timing for lesion correction. Intervention enhanced with percutaneous options now allows patients to benefit from mechanical correction.
