Following patients with prosthetic valve replacement is quite difficult. Indeed, fibrosis, calcification and tearing of the leaflet are probably the fate of most bioprosthetic valves after 10 years. Separating valve dysfunction from other causes of symptoms, such as diminished left ventricular contractility, coronary arterial disease and pulmonary disease may be difficult. Catheterization is frequently different and risks are reported. Nowadays, the echo color Doppler is much more reliable even when the metallic structures in the mechanical valve cause echo reflections and shadowing which mask events distal to the struts. Therefore, detection of thrombus or vegetation around the metallic struts is not easy.
