Why the study?
Can left ventriculography and coronary angiography effectively diagnose left atrial tumors?
Can left ventriculography and coronary angiography effectively diagnose left atrial tumors?
Left ventriculography is a sensitive diagnostic test for left atrial tumors, and coronary arteriography can provide independent evidence by visualizing tumor vessels.
May support adjunctive ventriculography for left atrial tumors; leaves open utility versus contemporary noninvasive imaging.
The left ventriculograms and pulmonary and coronary angiograms of eight patients with left atrial (LA) tumors were reviewed. The patients' ages ranged from 52 to 65 years. In each case the tumor was outlined during left ventriculography. Coronary arteriography allowed visualization of tumor vessels in six cases (six of seven myxomas). Two of the patients had significant coronary obstructions. It is concluded that a left ventriculogram is a sensitive diagnostic test for the presence of LA tumors. Coronary arteriography is indicated in patients with LA tumors in this age group and is likely to provide independent evidence of the presence of an LA tumor.
