[Diagnostic angiography of antero-apical ventricular aneurysms. Contribution of multiple projections. Apropos of 42 cases].
The wide variety of definitions covering the term, left ventricular aneurysm, at the present time suggests the need for a radiological description based on pathological findings. The presence of the aneurysm on angiographic images is shown by a persistent left ventricular deformity during diastole causing a pocket separated from the contractile left ventricle by an annular constriction. A study of 42 cases of anterior apical ventricular aneurysms selected according to these criteria and investigated by multiple ventriculographic projections (LAO, RAO, anteroposterior and profile) demonstrated that the right anterior oblique projection alone is insufficient to ensure the diagnosis. An indirect sign suggestive of the diagnosis is a double outline due to the superimposition of aneurysmal and contractile zones. A complementary LAO projection, with or without a profile film, should be performed in order to confirm diagnosis and determine extent of lesion, this conditioning the result of surgery.
