Altered hypoxia‐inducible factor‐1 alpha expression levels correlate with coronary vessel anomalies [PDF]

Developmental Dynamics, 2009
AbstractThe outflow tract myocardium and other regions corresponding to the location of the major coronary vessels of the developing chicken heart, display a high level of hypoxia as assessed by the hypoxia indicator EF5. The EF5‐positive tissues were also specifically positive for nuclear‐localized hypoxia inducible factor‐1 alpha (HIF‐1α), the oxygen‐

Great Vessel and Coronary Artery Anatomy in Transposition and Other Coronary Anomalies [PDF]

JACC: Cardiovascular Imaging, 2013
In patients with transposition of the great arteries, the identification of coronary anatomy is fundamental to optimal surgical outcome. A number of classifications describing the coronary vessels' origin and course in transposition of the great arteries have been published. However, all are limited to operative or pathological case series.

A Case of Coronary Vessel Anomaly of the Left Circumflex Artery Originating from the Right Coronary Artery with Variant Angina

Korean Circulation Journal, 2004
Coronary vessel anomaly is a rare disease, with an incidence of about 0.6-1.3% of patients receiving coronary angiography. The ischemia in coronary vessel anomalies is due in most cases to atherosclerosis or compression of the coronary artery by a great vessel, but occasionally spasm of a coronary vessel anomaly is responsible for the pathogenesis of ...

Short Chronic Total Occlusion Stump Creating an Optical Illusion of an Anomalous Coronary Artery: A Pseudo Anomaly

Journal of the Practice of Cardiovascular Sciences, 2023
Coronary artery anomalies are often asymptomatic and detected incidentally during coronary angiography, cardiac surgery, or autopsy. However, sometimes in chronic total occlusion, the distal part of a vessel is well collateralized from the contralateral ...

Hemodynamic Relevance of Anomalous Coronary Arteries Originating From the Opposite Sinus of Valsalva-In Search of the Evidence

Frontiers in Cardiovascular Medicine, 2021
Coronary artery anomalies (CAA) represent a heterogeneous group of congenital disorders of the arterial coronary circulation, defined by an anomalous origin of the coronary ostium and/or vessel course.
