| pubmed-article:4039738 | pubmed:abstractText | Experience with 30 consecutive patients who had a total of 32 primary cardiac tumors and who underwent two-dimensional echocardiographic examinations between January 1977 and June 1983 was reviewed. Most of the tumors were atrial myxomas (20 left and 4 right), and 30 were identified on echocardiography. Twenty-five patients, including 21 of 22 with atrial myxoma, underwent surgical resection on the basis of the echocardiographic examination, without preoperative angiocardiography. When the morphologic characteristics of the left atrial myxomas were studied statistically in relation to clinical abnormalities, large tumor size was most closely related to the number and type of associated clinical and laboratory abnormalities. The single exception was embolization, which correlated with echocardiographic tumor consistency. Since the introduction of two-dimensional echocardiography, the yearly incidence of cardiac tumor diagnosis at this clinic has increased several fold and the incidence of unexpected intraoperative diagnosis has been very low (one case). Echocardiography is the method of choice for clinical diagnosis. It has replaced angiocardiography for routine preoperative assessment, permits early diagnosis of cardiac neoplasms and provides insight into the pathophysiology of primary cardiac tumors. | lld:pubmed |
