Although cardiac papillary fibroelastoma is rare, it is the most common primary tumor of cardiac valves. The clinical presentation of these tumors varies from asymptomatic to embolic complications. We report an asymptomatic case of papillary fibroelastoma of mitral valve which was diagnosed by transthoracic echocardiography. The tumor was successfully resected by surgery.

10.Influence of pivot distance on the performance of a mechanic heart valve.

Based on the analysis of the influence of the valve pivot distance on the performance of mechanical heart valve (MHV), such as the valve opening and closing features, flow field characteristics and the valve assembly properties, value constraints of the valve pivot distance were established, and the reasonable valve was obtained by means of the finite element method. It can be shown that the central flow characteristics of the valve could be enhanced with the increasing of the ratio of pivot distance to valve inner diameter, but the plastic deformation of the ring could be liable to occur in the MHV assembly process. It is proved that the valve of specifications can be designed in similar ratio of pivot distance to valve inner diameter according to the result of the valve performance experiment.
