Within time, the walls become adherent but until that happens the presence of two walls can be easily confused with a root abscess * * * * * * * * * * * * * * * * * * * * * * * Evaluate prosthetic valves at baseline When valve is known to be functioning normal for reference for future evaluations. * Evaluate prosthetic valves at baseline When valve is known to be functioning normal for reference for future evaluations. * * In this image taken immediately post surgery, mild perivalvular regurgitation is present. In most cases mild perivalvular regurgitation resolves over time. * VALVED CONDUITS Part of repair of some forms of complex congenital heart disease Not all conduits contain valves and those that do may use either bioprosthetics or mechanical prostheses. Conduit itself often has a characteristic echocardiographic appearance due to the conduit material and the ribbed design * REPAIR Adult patients with aortic valve pathology are seldom candidates for valve repair. Valve replacement is usually necessary for significant aortic stenosis or regurgitation. * MITRAL VALVE REPAIR * MITRAL VALVE REPAIR Repairing rather than replacing Several advantages and is being performed with increasing frequency. Mitral and tricuspid valve pathologies should be considered for valve repair Operative mortality associated with repair of these valves is lower than that associated with their replacement. * MITRAL VALVE REPAIR Selection of repair vs. replace is dependent upon Etiology, morphology and severity as well as the status of the left ventricle. Replacement for :severe scarring and deformation by a disease process such as advanced rheumatic heart disease advanced lupus another inflam
