International audienceLeft ventricular remodeling (LVR) typically manifests as compensatory changes in ventricular mass, composition, and volume as a response to cardiac performance inadequacy..
Introduction
Anomalous origin of the left circumflex artery from the pulmonary artery (ACXAPA) is a very rare coronary anomaly. Only a few cases have been reported until today, from incidental findings to autopsy report after sudden cardiac death.
Case
We report here for the first time the case of a man, previously monitored for asymptomatic left ventricular non-compaction cardiomyopathy (LVNC), who presented with non-ST myocardial infarction, and was diagnosed with ACXAPA. Complementary tests confirmed ischemia in the corresponding territory and the patient was referred to surgery for reimplantation of the circumflex artery.
Discussion
LVNC is a rare congenital cardiomyopathy whose association with coronary anomalies, but not with ACXAPA, had previously been described until now. A related embryological origin could potentially explain this association. The management of a coronary anomaly should indicate dedicated multimodal cardiac imaging in order to not disregard the association with an underlying cardiomyopathy.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
