Hyper-Dominant Left-Circumfl ex Artery Supplying Left Anterior Descending Artery Territory

Abstract

We report an interesting case of a 77-year-old woman who presented with a non-ST-segment-elevation myocardial infarction. Coronary angiogram revealed a critical stenosis of the

proximal right coronary artery as the culprit lesion. Left coronary angiography showed an extraordinarily long vessel supplying left circumfl ex and partly left anterior descending

artery territory. We aimed to present and discuss this very rare congenital coronary abnormality and its possible clinical consequences.

Sol Ön Inen Arter Bölgesini Besleyen Hiper-Dominant Sol Sirkümfl eks Arter

Abstract

Bu olgu sunumunda 77 yaşında ST-segman elevasyonu olmayan miyokart enfarktüsü ile değerlendirilen bir bayan hastaya değinilecek. Yapılan koroner anjiyografi de proksimal sağ

koroner arterde ciddi bir darlık bu duruma neden olan lezyon olarak saptandı. Sol koroner anjiyografi de alışılagelmişin dışında uzun bir sol sirkümfl eks arteri görüldü. Bu damar aynı

zamanda sol ön inen koroner arter bölgesinin belirli bir kısmını besliyordu. Amacımız bu çok seyrek görülen konjenital koroner anomaliyi oluşabilecek klinik sonuçlarıyla sunmak ve

tartışmaktır. ( Sakarya Med J 2017, 7(2):112-115 ).
