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‐

The Role of MDCT Coronary Angiography in the Detection of Benign Varieties and Anomalies of Coronary Blood Vessels—A Narrative Review

Medicina (Lithuania)
Coronary arteries may vary in quantity, point of origin, or course. These variations fall under the category of anatomical variants/anomalies of the coronary arteries, representing congenital abnormalities of the coronary vascular system. Generally, they are benign, asymptomatic, and identified inadvertently during coronary angiography conducted for ...

Great Vessel and Coronary Artery Anatomy in Transposition and Other Coronary Anomalies

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.
