Case reports of two primary cardiac neoplasms

Two cases of a primary tumor of the left auricle have been presented in the hope that by the accumulation of clinical data on such cases more accuracy in diagnosis may eventually be possible. Both patients presented findings suggestive of rheumatic heart disease with mitral stenosis and cardic decompensation. They were atypical, however, in that they failed to respond to the initial therapy for congestive heart failure, and their illness progressed rather rapidly in spite of such therapy.
