[ANOCOR registry]. / Le registre ANOCOR.

Anomalous aortic origin of the coronary arteries are congenital anomalies with many anatomical forms. Due to the varying risk of sudden death, these abnormalities must be classified accurately. There are still questions about the mechanism and individual risk of sudden death, the natural history of these abnormalities and the benefits of a surgical correction. Large-scale observational registries may provide more evidence-based data to practitioners caring for the patients concerned. The ANOCOR registry, the largest in size published to date, enrolled 472 patients (mean age 63 years) with 496 coronary abnormalities. The angiographic representation (with invasive coronary angiography or coronary CT angiography) according to the coronary artery and initial ectopic course could be specified with the identification of two main phenotypes: the circumflex artery (n = 235) with a retroaortic course in 97% of cases and the right coronary artery (n = 165) with an interarterial course in 89.7% of cases. Two left coronary anatomical forms have been confused by non-expert cardiologists: those with a retropulmonary or interarterial course. Sudden death related to coronary anomaly was a very rare mode of presentation (3 patients or 0.6% of the cohort) in this population with very few young patients < 35 years (11 cases or 2.3% of the cohort).

[Very late drug-eluting stent thrombosis by stent fracture]. / Thrombose coronaire très tardive par fracture du stent actif. Cas clinique et revue de la littérature.

The superiority of drug-eluting stents in reducing the risk of in-stent restenosis compared to bare-metal stents is no longer challenged. Nevertheless, the drug-eluting stents may carry long-term risk of late and very late stent thrombosis. The promoting factors of this complication are usually divided into three chapters depending on the patient, the procedure and the stent. Indeed, the literature has reported several parameters related to the stent itself, such as its length, the malapposition, its diameter, but also more rarely the occurrence of stent fracture. We present the case of a patient admitted for myocardial infarction after a very late thrombosis of Cypher drug-eluting stent four years after its implantation and related to stent fracture.
