Abstract:
Cardiac myxomas can be fatal and left ventricular (LV) myxomas with papillary muscle and mitral valve (MV) involvement are rare. The following case is that of a 55-year-old woman who developed signs and symptoms of pulmonary hypertension. Imaging revealed a contractile mass in the LV that was in continuum with the papillary muscles and affected MV function. Her clinical course, radiologic, and hemodynamic findings are discussed. Finally, her surgical extraction technique is described in addition to potential complications encountered.
