Abstract
Left ventricular pseudoaneurysm and left ventricular free wall rupture are rare but
life-threatening complications of acute myocardial infarction. Dynamic systolic compression
of the coronary arteries is almost always due to myocardial bridging. However, it
has rarely been described in patients with ventricular aneurysms and pseudoaneurysms.
We present a case of a patient with recent myocardial infarction who presented with
recurrence of chest pain and coronary angiogram showing patent vessels however with
systolic compression of the distal left anterior descending coronary artery as a first
clue to postinfarct left ventricular pseudoaneurysm.
Résumé
Le pseudoanévrisme du ventricule gauche (PVG) et la rupture de la paroi libre du ventricule
gauche sont rares, mais les complications de l’infarctus aigu du myocarde mettent
en danger la vie du malade. La compression systolique dynamique des artères coronaires
est presque toujours due aux ponts myocardiques. Toutefois, elle a rarement été décrite
chez les patients ayant des anévrismes ventriculaires et des pseudoanévrismes. Nous
présentons le cas d’un patient qui, après avoir récemment subi un infarctus du myocarde,
a eu une récurrence de la douleur thoracique. Il a passé une angiographie coronarienne
qui montrait des vaisseaux non obstrués, mais une compression systolique de l’artère
interventriculaire antérieure distale comme premier signe de PVG post-infarctus.
