[Coronarography in the study of myxoma. Apropos of a case diagnosed by this technic].
In a 59 years old woman presenting a rudimentary picture of myocardial infarction, ventriculograms confirm a limited necrosis and coronarography shows an abnormal vascular image, evoking an intracardiac tumor, while the arteries are free of atherosclerosis or thrombosis on angiography. Although auscultation and echography are normal, the diagnosis of myxoma will be confirmed by angiocardiography, then by surgery and pathology. The advantage of selective coronary angiography in myxomas is considered with 24 cases from the literature having undergone this examination, including 20 cases, among which ours, which present an aspect of "tumoral vascularisation". The particularities of coronarography (aneurysms, embolic obstruction, origin and aspect of hypervascularisation) are analyzed. This technique appears very useful, not only to detect a complication of the tumor or an associated coronaritis, but also to help in the diagnosis of myxomas in cases where angiocardiography or mostly echocardiography are deficient.
